Mullite bricks are high-alumina refractory products with mullite (3Al2O3·2SiO2) as the main crystal phase. The products are divided into sintered mullite bricks and fused mullite bricks. Sintered mullite bricks are mostly made of synthetic mullite clinker and high-alumina bauxite clinker as raw materials, and are made through batching, high-pressure molding, and high-temperature firing, with the firing temperature being above 1600℃.
1. High temperature resistance: Mulet bricks have excellent thermal stability and deformation resistance in high temperature environments, and the firing temperature exceeds 1600℃.
2. Thermal shock stability: It has excellent thermal shock stability and can maintain integrity in an environment with rapid temperature changes.
3. Low high temperature creep rate: Low creep rate at high temperature ensures that its shape and performance remain stable under high stress conditions.
4. Corrosion resistance: It has strong corrosion resistance to acid slag and is suitable for use in various corrosive environments.
1. Blast furnace hot blast stove: suitable for lining of industrial furnaces with temperatures exceeding 1200℃.
2. Steel industry: Applicable to torpedo tank car parts, slag lines, and electric arc furnace tops.
3. Ceramic and glass industry: Applicable to the regenerator arch and top structure of ceramic kilns and glass melting furnaces.
