Silica Mullite Brick
Product Information
Silicon-mullite brick is a high-grade refractory material. The main raw materials include high-alumina bauxite clinker and silicon carbide, which are made through processes such as mixing, molding, drying and high-temperature firing. The key step is the high-temperature firing stage, which forms an ideal mullite crystal structure by reasonably controlling the temperature and atmosphere. It has high refractoriness, excellent wear resistance and good thermal shock resistance. It can maintain stability in high temperature environments and is not easy to crack or peel off.
Feature: High refractoriness; Excellent thermal shock resistance; Good chemical resistance; High mechanical strength; Low thermal expansion.
Silicon-molybdenum andalusite bricks are mainly composed of special high-alumina bauxite, large-crystal silicon carbide, andalusite, fused white corundum and other raw materials. They are made by adding high-quality binders and additives, and are formed by high-pressure molding and high-temperature sintering. This production process ensures the high density and excellent physical properties of silicon-molybdenum red bricks.
Features: High strength and wear resistance; Good durability; Good thermal insulation performance; Good high temperature performance; High thermal shock resistance.

Application
Silicon-molybdenum andalusite bricks are widely used in transition zones and cooling zones of large and medium-sized cement rotary kilns. Due to its excellent fire resistance and wear resistance, silicon-molybdenum red bricks can effectively improve the service life and performance of equipment.
In cement rotary kilns, silicon-molybdenum bricks are mainly used in transition zones, preheating zones, tertiary air ducts, five-stage preheaters, and lime kiln unloading chutes. They are resistant to erosion, spalling, and good thermal shock stability.
