Application case of wear-resistant ceramic lining plate on furnace top equipment.

The charge must be equipped with wear-resistant ceramic linings at the blanking points and material flow rubbing points of the charging strip on the top of the bell furnace. The working conditions of the wear-resistant ceramic linings determine their high-temperature resistance, wear resistance, and the performance requirements of impact resistance, high-temperature resistance, wear resistance, and impact resistance the wear-resistant ceramic liner determines its service life, and its service life is directly related to the reliability of the furnace top charging equipment, which directly affects the blast furnace. Stabilizing the production cycle is also closely related to the blast furnace shutdown rate and the economic loss of the iron smelting plant.

The wear-resistant ceramic lining plate is made of aluminum oxide as the main raw material and rare metal oxides as the flux. After melting at a high temperature of 1700 ° C, it is combined with special rubber and high-strength organic adhesives. It can also be used alone. Ceramic backing plate as lining. The wear-resistant ceramic lining plate has high hardness, the Rockwell hardness is 80-90, which is higher than that of minerals such as ore and coal ash; the wear resistance is strong, the wear resistance is 266 times that of the steel plate, the density is small and easy to process, and the rubber Vulcanized together can be cut, twisted and assembled, not limited by the shape, size, and installation position of the equipment.

The wear-resistant ceramic lining plate is used as the lining plate of the blast furnace charging the car, which reduces the wear and tear of the equipment, improves the reliability of the blast furnace charging equipment, and ensures the stability and high output of the blast furnace. The size of the wear-resistant ceramic lining is mainly related to the size of the ore, impact force, temperature, etc. It is also a specific analysis of the specific situation and is not limited to which one is used.
