Main components of refractory materials such as breathable bricks, water-resistant bricks, and castables

Refractory materials are widely used in various industrial sectors, including metallurgy, chemical processing, petrochemicals, machinery manufacturing, and power generation, with significant consumption in the metallurgical industry. In steelmaking, commonly used refractory materials include permeable bricks, water-cooled bricks, electric furnace lids, castables, runner brick, and magnesia-carbon bricks for steel ladles and refining furnaces. These refractory materials vary significantly in their main and additive components. From a chemical perspective, refractory materials are composed of minerals such as corundum, mullite, and magnesia, with major components including alumina and magnesia.
