Clay refractory bricks are more widely used in industry than other refractory bricks. This is not only due to its physical - chemical properties (neutral chemical properties, good thermal stability, adequate satisfactory refractoriness, slag resistance, etc.), but also because of the manufacture of clay refractory brick raw material base , While the process of manufacturing process research and improvement are also more. It is no exaggeration to say that any kind of thermal equipment should be used with some clay refractory bricks. For example, blast furnace, flat furnace, the production of various silicate kilns (ceramics, refractory bricks, glass, cement, enamel, etc.), a variety of heat exchange equipment (hot air gun, regenerator, heat exchanger), gas Furnace, coke oven, electric melting furnace, melting a variety of non-ferrous metal furnace, boiler equipment, combustion chamber and other thermal equipment.
