UB Groups manufactures and supplies the full range of refractory materials: high alumina bricks, fireclay bricks, castables, ceramic fibre products, and monolithic refractories for industrial furnaces, rotary kilns, boilers, and high-temperature processing equipment across India.
What Are Refractory Materials?
Refractory materials are engineered heat-resistant materials designed to maintain structural integrity and chemical stability at temperatures exceeding 1,000°C, conditions that would cause conventional construction materials to soften, deform, or react. They form the working lining of furnaces, kilns, boilers, reactors, and other thermal processing equipment across virtually every major industry
The defining properties of quality refractory materials include high refractoriness (the ability to withstand extreme heat without melting), thermal shock resistance under rapid temperature cycling, abrasion resistance in environments with moving charge or material, corrosion resistance against molten slag, metal, glass, or chemical attack, and the mechanical strength to carry loads at operating temperature.
Refractory materials divide broadly into two families: shaped products such as high-alumina bricks, fireclay bricks, insulation bricks, and refractory fire bricks; and unshaped or monolithic refractories such as castables, mortars, ramming mixes, and gunning compounds. Industrial furnace design typically combines both a dense working lining in direct contact with the heat source and a thermal insulation layer behind it to manage heat loss and improve energy efficiency.
Selecting the right refractory material for a given application requires precise knowledge of operating temperature, thermal cycling pattern, chemical environment, mechanical load, and maintenance access. A wrong specification leads to premature lining failure, unplanned downtime, and significantly higher operating costs
Leading Refractory Materials Manufacturer for Industrial Applications
For over two decades, UB Groups has built its reputation as one of India’s reliable refractory materials manufacturers, supplying shaped bricks, monolithic refractories, and ceramic fibre products to customers in the steel, cement, glass, foundry, petrochemical, power, and non-ferrous metal sectors.
Operating from Ludhiana, a strategically located industrial hub in Punjab, UB Groups combines in-house manufacturing capability with deep application engineering knowledge. The company does not simply supply products; it works with procurement teams, plant engineers, and maintenance managers to specify the right refractory solution for each zone of every furnace or kiln.
This application-level engagement, backed by 23 years of field experience across diverse industrial heating systems, is what separates UB Groups from commodity refractory suppliers. The team understands that a rotary kiln burning zone has different demands from a ladle lining, that a glass tank wall operates under chemical conditions entirely different from a heat treatment furnace, and that specifying the wrong alumina content or density grade can cost a plant weeks of production.
Types of Refractory Materials We Manufacture and Supply
UB Groups manufactures and supplies a complete range of shaped and monolithic refractory products. Every product category below is available in multiple grades to match specific operating conditions.
High Alumina Bricks
Manufactured with 45% to 90%+ Al₂O₃ content, high alumina bricks deliver superior refractoriness, excellent slag resistance, and high load-bearing capacity at elevated temperatures. Used extensively in the burning zones of rotary kilns, steel furnace linings, glass tank walls, and petrochemical reactors where standard fire clay bricks reach their performance limits.
Up to 1,800°C | Dense & Low-Porosity Grades
Fire Clay Bricks
Fireclay bricks are the workhorses of the refractory industry reliable, cost-effective, and available in a wide range of grades suited to temperatures up to 1,500°C. UB Groups’ fire clay bricks are used in boiler linings, heat treatment furnaces, foundry cupolas, and the cooler sections of cement kilns where the chemical environment is moderate.
Up to 1,500°C | Standard & Dense Grades
Refractory Fire Bricks
UB Groups manufactures refractory fire bricks in standard, special shapes, and tapered formats to accommodate the geometry of different industrial furnaces, arches, and kilns. These bricks combine good thermal shock resistance with adequate compressive strength for general-purpose high-temperature applications across multiple industries.
Custom Shapes | High Thermal Shock Resistance
Insulation Bricks
Lightweight insulation bricks provide the thermal barrier behind the working lining in most industrial furnace and kiln designs. Their low thermal conductivity and low thermal mass reduce heat loss through the shell, improving fuel efficiency and cutting operating costs. UB Groups supplies insulation bricks in grades suited to backup lining in heat treatment furnaces, boilers, and kilns.
Low Thermal Conductivity | Multiple Density Grades
Refractory Castables
Refractory castables are mixed with water and cast or vibrated into position, making them ideal for complex geometries, curved surfaces, furnace roofs, ladle linings, kiln hoods, and areas where brick installation is impractical. UB Groups supplies standard, low-cement, ultra-low-cement, and insulating castable grades for different temperature and service requirements.
Pourable | Pumpable | Complex Geometries
Refractory Mortars
Refractory mortars bond brickwork joints and prevent hot gas penetration through the lining. UB Groups supplies air-setting and heat-setting mortars formulated to match the composition and thermal expansion of the adjacent brickwork, maintaining joint integrity through thermal cycling.
Air-Setting & Heat-Setting | Joint Bonding
Ceramic Fiber Products
Ceramic fibre blankets, modules, boards, and papers are used for backup insulation, expansion joint filling, furnace door seals, and the lining of heat treatment furnaces and industrial heating systems where low thermal mass and rapid heat-up are priorities. Their light weight reduces structural loading compared to brick systems.
Low Thermal Mass | Fast Heat-Up | Lightweight
Refractory Bricks Manufacturers in India
The Indian refractory bricks manufacturing sector has grown significantly alongside the country’s steel, cement, and glass industries. UB Groups operates within this landscape as a manufacturer with direct technical capability — meaning the company controls the production process, raw material sourcing, and quality testing rather than acting as a trading intermediary.
As refractory brick manufacturers in India, the company supplies dense refractories and shaped bricks in consistent quality to customers across the country. This consistency matters in industrial procurement: a plant engineer specifying a high-alumina brick for a rotary kiln burning zone needs to know the alumina content, apparent porosity, and cold crushing strength will be the same batch to batch.
UB Groups maintains documentation for each product category covering chemical composition, physical properties, and temperature ratings, giving procurement teams and plant engineers the technical basis to compare and specify with confidence.
Refractory Fire Bricks Manufacturer in India
As a refractory fire bricks manufacturer in India, UB Groups produces both standard-format and custom-shape fire bricks for arches, cylindrical kilns, and irregular furnace profiles. The manufacturing process begins with raw material selection — the grade and purity of the fireclay or alumina aggregate determines the final product’s temperature rating and resistance properties.
UB Groups’ fire bricks are pressed at controlled pressure to achieve the target density and porosity values, then fired in kilns at temperatures that develop the ceramic bond and establish the final refractory properties. Each batch goes through dimensional checking, visual inspection for cracks and laminations, and physical testing before release.
The company supplies refractory fire bricks for use in steel plant reheating furnaces, cement plant kiln hoods and cooler sections, foundry furnace linings, industrial boilers, and a range of other high-temperature applications across India.
Trusted Refractory Fire Bricks Supplier
Being a reliable refractory firebrick supplier means more than having stock available. It means delivering consistent product quality, providing accurate technical datasheets, meeting lead times, and offering application guidance when a customer is selecting grades for a new lining or a repair campaign.
UB Groups has built its supplier relationships over 23 years on exactly these terms. Customers in the steel and cement industries, where an unplanned relining can cost significant production downtime, value the reliability of working with a supplier that understands the urgency and technical precision their operations demand.
The company supplies refractory fire bricks across India, with customers in Punjab, Haryana, Rajasthan, Gujarat, Maharashtra, and other industrial states. Whether the requirement is a full kiln relining campaign, a batch of specialty shapes, or an emergency supply for a running repair, UB Groups has the inventory depth and manufacturing flexibility to respond
Applications of Refractory Materials

Industries We Serve
UB Groups supplies refractory materials across seven major industrial sectors. Each sector has distinct refractory requirements shaped by its operating temperatures, chemical environments, and production cycles.
Steel Industry Foundry Industry Glass Industry Petrochemical Industry Power Plants Non-Ferrous Metal Industry
The steel industry is among the most demanding refractory consumers — ladle linings face thermal shock from liquid steel at 1,600°C+, combined with slag corrosion and mechanical impact. The cement industry requires robust kiln linings that handle steady high-temperature operation plus the chemical attack of clinker and alkali vapours. Foundries need linings that tolerate repeated heat cycles as furnaces are charged, melted, and tapped. Glass furnaces impose some of the harshest corrosion conditions in industry, with molten glass dissolving inadequately resistant refractories rapidly. Petrochemical plants combine high temperatures with chemically reactive atmospheres, demanding refractories with both thermal stability and chemical resistance. Power plant boilers require reliable firebox linings that operate continuously. Non-ferrous metal processing — aluminium, copper, and others — has specific flux and slag chemistry that calls for carefully selected refractory grades
Manufacturing Process and Quality Control
The quality of a refractory product is determined at every stage of its manufacture — not just at final inspection. UB Groups applies a structured process from raw material intake through shipment.
Raw Material Selection
Each batch of raw material — fire clay, calcined alumina, bauxite, or aggregate — is assessed for chemical composition and particle size distribution before entering production. Sub-specification raw material is rejected at intake.
Engineering & Forming
Mixes are prepared to established formulations. Bricks are pressed at controlled pressure in steel dies to achieve target density and porosity values. Custom shapes are produced using specialised tooling.
Firing
Pressed bricks are fired in kilns at temperatures calibrated to develop the ceramic bond and achieve the final refractoriness. Firing schedules are controlled for temperature uniformity and hold times.
Thermal Shock Testing
Samples from each production batch undergo thermal shock testing — rapid cycling between high and low temperatures — to verify the material’s resistance to cracking during service in industrial furnaces and kilns.
Strength Testing
Cold crushing strength, modulus of rupture, and, where relevant, hot modulus of rupture are tested to verify structural integrity at room and operating temperatures.
Final Inspection
Every pallet is checked for dimensional accuracy, surface condition, and absence of cracks, laminations, or foreign inclusions before packaging and despatch. Batch records are retained for traceability.

Frequently Asked Questions
Refractory materials are heat-resistant materials engineered to withstand temperatures above 1,000°C, mechanical stress, and chemical attack in industrial environments. They line furnaces, kilns, boilers, and reactors where standard materials would fail. Common types include fire bricks, high alumina bricks, castables, and ceramic fiber products
Fire bricks are a category within refractory bricks, typically made from fire clay and rated for temperatures up to around 1,400–1,500°C. ‘Refractory bricks’ is a broader term covering all heat-resistant shaped bricks, including high alumina bricks, silica bricks, magnesia bricks, and others rated from 1,100°C to well above 1,800°C depending on composition.
Refractory materials are used across steel, cement, glass, foundry, petrochemical, power generation, and non-ferrous metal industries. Any plant operating furnaces, kilns, boilers, or high-temperature reactors depends on quality refractory lining for operational safety and thermal efficiency
Choose a manufacturer with documented industry experience, the ability to provide application-specific recommendations, rigors quality testing, and a track record across industries similar to yours. Verify that they can supply technical datasheets with chemical composition and physical property data. UB Groups has 23+ years of experience serving steel, cement, glass, foundry, and petrochemical sectors.
Temperature ratings vary by product. Fireclay bricks handle up to approximately 1,400–1,500°C. High alumina bricks with 70–90% alumina content withstand 1,600–1,800°C. Specialised refractories for steel furnace and glass tank applications are rated higher depending on composition and density. Selecting the right temperature rating for your application is as important as selecting the rated temperature.
Refractory linings protect furnace and kiln shells from extreme heat, chemical corrosion, and mechanical wear. They retain heat inside the vessel, directly improving energy efficiency and reducing fuel costs. A degraded or failed refractory lining causes unplanned downtime, structural damage to the furnace shell, and significant production losses.
Monolithic refractories are unshaped or formed-in-place refractory products that do not use pre-formed bricks. They include castables, mortars, ramming mixes, gunning mixes, and plastics. Monolithic refractories are poured, gunned, or rammed into position, making them well-suited for complex furnace geometries, rapid repair applications, and large surface areas where bricklaying would be slow or impractical
UB Groups brings over 23 years of refractory manufacturing experience, led by directors Bipin Mishra and Sachin Mishra, who work directly with customers on specification and supply. The company covers seven major industrial sectors, manufactures a complete range of shaped and monolithic products, applies multi-stage quality control, and supplies pan-India with the responsiveness that industrial procurement demands
Dense refractories are heavy, high-strength materials for direct contact with flame, molten material, or abrasive environments. Insulation bricks are lightweight, low-thermal-conductivity materials placed behind the working lining to reduce heat loss. Most industrial furnace designs combine both: dense bricks at the working face and insulation bricks in the backup lining
Yes. UB Groups supplies refractory materials pan-India from its base in Ludhiana, Punjab, serving customers in the steel, cement, glass, foundry, petrochemical, power, and non-ferrous metal industries across multiple Indian states.
Refractory castable is a concrete-like mixture of refractory aggregate, binder, and additives mixed with water and placed by casting, vibration, or pumping. It is used for boiler linings, furnace roofs, ladle linings, kiln hoods, and complex shapes that shaped bricks cannot fill efficiently
Thermal shock resistance is a material’s ability to withstand rapid temperature changes without cracking or spalling. It is critical in applications with repeated heating and cooling cycles, such as foundry furnaces, ladle pre-heaters, and heat treatment furnaces. UB Groups tests all products for thermal shock resistance before despatch.
Refractory mortar bonds brickwork joints and prevents hot gas penetration through the lining. It must match or exceed the temperature rating of the bricks it bonds and have compatible thermal expansion to prevent joint failure during thermal cycling in furnaces and kilns.
Yes. Bipin Mishra and Sachin Mishra lead a team that provides application-specific recommendations based on your operating temperature, chemical environment, thermal cycling pattern, and structural requirements. This technical advisory support is part of UB Group’s standard engagement with customers
High alumina bricks contain 45–90%+ Al₂O₃, giving them superior refractoriness, better resistance to chemical slag attack, higher load-bearing capacity at elevated temperatures, and better abrasion resistance. They are preferred for the most demanding zones in steel furnaces, rotary kilns, and glass tanks where fire clay bricks reach their performance limits.
UB Groups applies multi-stage quality control covering raw material verification, in-process checks on dimensions and composition, thermal shock testing, cold crushing strength testing, and final visual and dimensional inspection before despatch. Batch records are maintained for traceability.
