Bricks

Hard firebrick is a kind of alumina silicate brick containing 35-45%, and the refractories are SK 32-34. Brick is made of refractory clay, calcined limestone, mullite and other raw materials, with good wear resistance, peeling resistance, corrosion resistance. It has the characteristics of low porosity,

Hard firebrick is a kind of alumina silicate brick containing 35-45%, and the refractories are SK 32-34. Brick is made of refractory clay, calcined limestone, mullite and other raw materials, with good wear resistance, peeling resistance, corrosion resistance. It has the characteristics of low porosity, high strength, heat peeling, wear resistance, creep resistance, etc., and is widely used in the lining of coke oven, glass kiln, cement rotary kiln, lime kiln, various incinerators and heating furnaces.

Silica brick is made of quartz containing more than 93% of silicon as the main raw material. It is a firebrick made by high temperature firing. It has strong corrosion resistance to acid slag, high softening degree under load, and does not shrink after refiring. It is mainly used for the partition wall of the carbonization chamber and the combustion chamber of the coke oven, the regenerator chamber of the steel furnace, the soaking furnace, the glass kiln and the ceramic firing kiln, and other supporting parts of the kiln. It is also used for high temperature bearing parts of hot blast furnaces and flat tops of acid furnaces. Characteristics of silicon brick: It has good high temperature fire resistance Ultra-high cold compression strength characteristics High temperature resistance, good fire resistance Low impurity content Excellent resistance to slag wear Repeated burns do not shrink. Application of silicon brick: Hot blast stove Coke oven Glass kiln Steel furnace Silicon brick specifications: Silica content is 94% to 96% Widely used in hot blast furnace, coke oven, glass kiln, steel furnace.
