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. High compressive strength (200-500 kg/cm²), high thermal shock resistance, as well as being chemically resistant and abrasion resistant, are other characteristics of fire bricks. Some of their main attributes are good insulation against heat, longevity, accurate dimensions, and energy efficiency. These qualities make them perfect to minimize fuel costs at high temperatures. Due to the high temperature and the need for safety in the industries of Ludhiana, such as steel plants and foundries, fire bricks are extremely important.
