The Function Of Semi Silica Brick

Semi - silica bricks are produced with using clay - based refractory materials of high SiO₂ content. They are finished by machine pressing and fired at high temperatures. The products feature low porosity, high density and high strength. In particular, the creep rate is very low, only about 0.08% at 1050℃ for (5 - 25h). During application, their outstanding advantages are high anti - penetration and acid - corrosion resistance. Therefore, semi - silica bricks are currently widely used in the linings of equipment such as coke ovens, non - ferrous metal smelting facilities and torpedo car.
