  Refractory castable is a new type of refractory that does not need to be fired at high temperature and is directly used after construction and baking. Unshaped refractory castable has simple production process, saves energy and labor, can be mechanized construction, has good integrity, is easy to repair and has a long life. Unshaped r efractory castables are usually classified according to the size of the porosity, the selected bonding agent or bonding method, the type of aggregate and the construction method. According to the porosity, it can be divided into dense refractory castables and insulated refractory castables. 1.High alumina bauxite. The high-alumina bauxite clinker calcined at high temperature is mainly used for high-alumina refractory materials, and can also be used to make fused brown corundum and sub-white corundum. In recent years, the homogenized bauxite clinker produced in my country has achieved good results in the application of monolithic re...
