The fire bricks in Ludhiana are highly advanced refractories that can stand up to very high temperatures and harsh conditions in the industry. Made from high-quality raw materials such as fire clay and high-alumina, these bricks are extensively used in furnaces, kilns, boilers, chimneys, and rolling mills to retain heat. The typical range of Al₂O₃ content in high alumina fire bricks is 40%-80%, and their temperature capacity goes from 1,200°C to 1,600°C. These bricks have a bulk density of 1.8-2.6 g/cm³, which provides them with great strength, besides having a low thermal conductivity (0.6-1.5 W/mK) and thus providing great insulation.
