refractory solutions for industries across India & beyond.
Fireclay Bricks
Fireclay bricks are the foundation of many industrial furnaces and kilns. With an alumina content of 30–45%, they provide excellent thermal resistance up to 1600°C. These bricks are known for their durability, mechanical strength, and resistance to thermal spalling, making them ideal for cement plants, ceramic kilns, boilers, and incinerators. Industries choose fireclay bricks because they balance affordability with performance, offering a long lining life at competitive pricing. At JK Refractory, our fireclay bricks are sourced and manufactured under strict quality standards, ensuring consistent performance and reliability.
High Alumina Bricks
High Alumina Bricks, with alumina content ranging from 45–90%, offer superior refractoriness of up to 1750°C. They are the preferred choice for steel plants, rotary kilns, ladles, and glass furnaces where both chemical resistance and high strength are critical. These bricks exhibit excellent resistance to slag and abrasion, significantly reducing downtime and replacement cycles. Compared to fireclay bricks, they provide a longer service life in high-demand applications. JK Refractory supplies high alumina bricks that meet stringent industrial standards, ensuring better productivity and efficiency for heavy industries.
Magnesia Bricks
Magnesia bricks are made from high-purity magnesite and are highly suited for basic slag environments, particularly in steelmaking and cement industries. They can withstand temperatures beyond 1800°C and provide superior resistance against basic slags, making them essential for converters, electric arc furnaces (EAFs), and cement rotary kilns. Their excellent thermal conductivity and volume stability help reduce heat loss while maintaining strong structural integrity under extreme conditions. JK Refractory delivers magnesia bricks trusted by steel and cement plants for high-stress areas that demand long-lasting linings.
Magnesia Carbon Bricks
Magnesia Carbon (Mg-C) bricks combine magnesia with carbon additives like graphite to provide unmatched resistance against thermal shock, slag penetration, and erosion. Widely used in steel converters (BOF/LD), EAFs, and ladle linings, these bricks are designed to perform in the most aggressive conditions. The carbon component helps resist slag corrosion while providing thermal shock stability. This makes Mg-C bricks indispensable in modern steelmaking, where longer lining life directly impacts production costs and efficiency. At JK Refractory, our magnesia carbon bricks are engineered for maximum durability and performance in high-temperature steelmaking operations.
Castables & Mortars
Refractory castables and mortars provide flexibility where shaped bricks cannot fit. Castables are used to line boilers, incinerators, induction furnaces, and other complex structures, ensuring seamless protection against heat and corrosion. Mortars, on the other hand, are used for joining bricks and repairing linings, ensuring strong bonds and consistent durability. Both materials offer superior thermal resistance and are easy to apply, making them ideal for maintenance and new construction projects. JK Refractory’s castables and mortars are formulated with high-quality raw materials to ensure maximum performance and reliability in diverse industrial environments.
