Refractory materials are generally divided into two categories, namely unshaped refractory and shaped refractory. The unshaped refractory material, also called as casting material, is a mixed powder granule composed of various aggregates or aggregates and one or more kinds of adhesives, and when in use, the unshaped refractory material must be matched with one or more kinds of liquids to be stirred uniformly, and has stronger fluidity. The firebricks are called firebricks for short. The refractory material is made by burning refractory clay or other refractory raw materials. Yellowish or brownish. Also called fire brick. A shaped and sized refractory material. The brick is divided into baked brick, unburnt brick, fused brick and refractory heat-insulating brick according to the preparation process; can be divided into standard bricks, common bricks, special shaped bricks, etc. according to the shape and size.
