1.Fire clay brick Description |
Fire Clay bricks are refractory bricks made of various raw materials including refractory clay, calcined soft clay, and soft clay. The alumina content is generally 30% -48% alumina refractory. It is a weakly acidic refractory product that can resist acid slag and acid gas erosion, has good thermal performance, and is resistant to rapid cooling and high temperature.
