Introduction to Silica Brick
Silica brick is a type of refractory brick that is mainly composed of silica (SiO₂). It has excellent thermal stability, high refractoriness under load, and good resistance to acid slag corrosion. These properties make silica bricks widely used in various high - temperature industries, such as steelmaking, glass manufacturing, non - ferrous metal smelting, and the cement industry. In steelmaking, silica bricks are commonly used in the roofs of open - hearth furnaces, soaking pits, and some sections of electric arc furnaces. In the glass industry, they are used in the superstructures of glass melting furnaces due to their ability to withstand high temperatures and resist the chemical attack of glass - forming materials.
