Refractory brick inherited what excellent characteristics of refractory clay

Refractory clay is a refractory degree is higher than 1580 degrees Celsius, refractory clay and can be used as refractory bauxite. They except has high refractoriness outside, can maintain volume stability at high temperature, and has the slag resistance, resistance to thermal shock, and certain mechanical strength. Refractory clay calcined abnormal firm, can be made of refractory brick.

Soft clay general is earthy, easily dispersed in water, and the liquid after mixing can form plasticity mud pie; half the baptism of soft clay powder is poor, the leaching of powder and liquid mixing can be formed after plasticity mud pie. The two kinds of clay used as binder in the production of refractory bricks and refractory products.

Hard clay often with a block or plate, generally in the water can not soak powder, refractory degrees higher, and the main raw material for refractory products. High alumina clay Al2O3 content is higher, the hardness and the proportion of large, high refractoriness, used to make advanced clay products.

Refractory clay is mainly used in the metallurgical industry, as the production of  refractory materials (various specifications of the brick wood) and unshaped refractory materials. Refractory clay in building materials industry to make cement kilns and glass melting furnace with high alumina brick, high aluminum phosphate brick, high aluminum casting brick etc… Also has important use in grinding industry, chemical industry and ceramic industry, raw materials can also be used as a manufacturing daily-use ceramics, industrial ceramics and building ceramics.
