Except for some raw materials, most of the raw materials used as refractory aggregates need to be calcined at high temperature. A series of physical and chemical reactions occur when raw materials are calcined, which plays a very important role in improving the composition, mineral composition and organizational structure of refractory materials and ensuring the volume stability and accuracy of appearance and size of refractory products.
