Products Description
The refractory degree of mullite bricks is relatively high, reaching above 1790 ℃. The starting temperature for load softening is 1600-1700 ℃. The compressive strength at room temperature is 70-260MPa. Good thermal shock resistance. There are two types of bricks: sintered mullite bricks and fused mullite bricks. Sintered mullite bricks are mainly made from high alumina bauxite clinker, with a small amount of clay or raw alumina added as a binder, and are formed and fired. Electric melted mullite bricks are made from high alumina, industrial alumina, and refractory clay as raw materials, with the addition of charcoal or coke particles as reducing agents. After forming, they are manufactured using the reduction electric melting method. The crystallization of fused mullite is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high-temperature performance mainly depends on the content of alumina and the uniformity of the distribution of mullite phase and glass.
