Products Description
According to the material, it can be divided into clay refractory bricks, high-alumina refractory bricks, first-class high-alumina refractory bricks, special-grade high-alumina refractory bricks, etc
Products Specifications
The national standard size of T-43 refractory brick is 230×114/94×65mm, and the size of T-44 refractory brick is 230×114/74×65mm.
Clay bricks are made of 40% soft clay and 60% hard clay clinker, and are properly proportioned according to certain particle size requirements. After being machine-shaped and dried, they are fired at a high temperature of 1380~1450C.
Clay bricks are weakly acidic refractory products, which can resist the erosion of acid slag and acid gas, and have slightly poor resistance to alkaline substances. Clay bricks have good heat resistance, can withstand rapid cooling and rapid heating, and have good thermal shock stability.
High alumina brick is an aluminum silicate refractory product with a content of aluminum oxide (Alz0,) higher than 48%. It is made of bauxite clinker or other raw materials with high alumina content after reasonable batching, machine pressing, drying and calcination. The softening temperature under load is high, and the refractoriness is above 1770°C.
It has good slag resistance and is used for the lining of masonry steelmaking electric furnaces, blast furnaces, hot blast furnaces, heating furnaces, and non-ferrous industrial smelting furnaces.
Aluminum melting furnaces and zinc smelting furnaces generally choose first-grade high-alumina refractory bricks and special-grade high-alumina bricks to build linings due to their special working conditions in the furnaces. They have good wear resistance, high strength, and strong erosion resistance. Long service life.
