Refractory Products
JK Refractory manufactures and supplies a range of refractory bricks, castables, mortars and custom shapes for industrial furnaces, kilns and high-temperature process equipment.
Fireclay Bricks
Fireclay bricks are widely used in industrial furnaces and kilns due to their balanced thermal resistance and mechanical strength. With alumina content typically ranging from 30–45%, these bricks provide reliable service up to approximately 1600°C.
Common applications include cement plants, ceramic kilns, boilers and incinerators where durability and cost efficiency are important.
High Alumina Bricks
High alumina bricks are designed for applications requiring higher refractoriness, improved load-bearing capacity, and resistance to aggressive operating conditions. These bricks are manufactured with alumina content ranging from medium to high grades, depending on application requirements.
They are commonly used in critical zones of steel furnaces, cement kilns, reheating furnaces and other high-temperature industrial equipment where thermal stability and mechanical strength are essential.
Refractory Grog
Refractory grog is a crushed and graded refractory material used in the manufacture of bricks, castables and ramming masses. It improves dimensional stability, reduces shrinkage, and enhances resistance to thermal shock in refractory products.
JK Refractory supplies grog in controlled particle sizes suitable for various refractory formulations and repair applications across multiple industrial sectors.
Custom Refractory Shapes
Custom refractory shapes are manufactured to meet specific design and operational requirements of industrial furnaces and kilns. These shapes are produced based on drawings, dimensions and material specifications provided by the client.
Custom shapes help optimize lining performance, reduce installation time, and ensure accurate fitment in complex furnace zones where standard bricks are not suitable.
Refractory Mortars
Refractory mortars are used for bonding refractory bricks and shapes, ensuring joint integrity and structural stability of furnace linings. These mortars are formulated to match the thermal and chemical properties of the associated refractory products.
JK Refractory supplies mortars suitable for various temperature ranges and applications, supporting reliable installation and long-term lining performance.
