Refractory material is fired from refractory clay or other refractory raw materials. Pale yellow or brownish. Refractory bricks are mainly used for building smelting furnaces, which can withstand high temperatures from 1580 degrees Celsius to 1770 degrees Celsius, also called fire bricks. A refractory material of a certain shape and size. According to the preparation process, it can be divided into fired bricks, non-fired bricks, fused bricks (fused cast bricks), refractory and heat-insulating bricks; according to shape and size, it can be divided into standard bricks, ordinary bricks, special bricks, etc. Refractory bricks can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment and can withstand various physical and chemical changes and mechanical actions at high temperatures, such as refractory clay bricks, high alumina bricks, silica bricks, magnesium bricks, etc. Next, we will introduce the nature of refractory br
