Refractory bricks are abbreviated as fire bricks. Refractory materials made by firing refractory clay or other refractory materials. Light yellow or brownish in color. Mainly used for building smelting furnaces, capable of withstanding high temperatures ranging from 1580 ℃ to 1770 ℃. Also known as fire bricks. Refractory materials with a certain shape and size. According to the preparation process, it can be divided into fired bricks, unburned bricks, electric melting bricks (cast bricks), and refractory insulation bricks; According to shape and size, it can be divided into standard bricks, ordinary bricks, special bricks, etc. High temperature building materials and structural materials that can be used as building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. For example, refractory clay bricks, high alumina bricks, silica bricks, magnesia bricks, etc.
