Classification of kiln refractory bricks

The main chemical composition of refractory bricks can be divided into six categories: aluminum-silicon refractory bricks, magnesia series refractory bricks, carbon-containing refractory bricks, zirconium-containing refractory bricks, siliceous refractory bricks, silicon carbide refractory bricks,

The size and shape of refractory bricks can be divided into standard refractory bricks, general refractory bricks, and special refractory bricks. Refers to refractory bricks whose size and shape meet certain requirements, including that the ratio of the length of the refractory brick to the size of the short side should not be too large, and the angle of the refractory brick should not be too small. Special type refractory brick means that the number of dimensions cannot be more than five, the ratio of the length of the long side to the dimension of the short side cannot be greater than 4, and the minimum angle of the refractory brick cannot be less than 15°.

According to the classification of the chemical properties of refractory bricks, refractory bricks are divided into acid refractory bricks, alkaline refractory bricks, neutral refractory bricks, such as silica bricks, zirconium quartz bricks are refractory bricks whose chemical properties are acidic, magnesia bricks, magnesia chrome bricks, magnesia bricks Calcium bricks are classified as alkaline refractory bricks, and high alumina bricks, clay bricks, and corundum bricks are classified as neutral refractory bricks.

According to the classification of the manufacturing process of refractory bricks, refractory bricks can be divided into fired bricks, non-fired bricks, fused cast bricks, and thermal insulation bricks. Corundum bricks are classified as pouring bricks and thermal insulation bricks are also classified as-sintered bricks, but they are reprocessed after sintering. High alumina bricks do not need reprocessing. Fused zirconium corundum bricks also require a lot of grinding processes in the later stage, and the manufacturing process is very characteristic.

The characteristics of refractory bricks, it is divided into high-alumina wear-resistant refractory bricks, heat-insulating lightweight heat-insulating refractory bricks, and anti-shedding high-alumina refractory bricks.
