The Application And Development Of Refractory Castable Should Conform To The Concept Of Environmental Protection And Economy

The application and development of refractory castables should conform to the concept of environmental protection and economy. The products should have the advantages of high wear resistance, long use time, low bulk density, high energy saving, etc. It can prolong the service life of refractory castable, effectively protect the equipment, reduce the heat loss of the system, reduce the system skinning and blocking, reduce the maintenance times and maintenance time, improve the operation rate of the system, and achieve the purpose of stable production, high yield and low energy consumption of the kiln system. The development trend of refractory castables is mainly to improve the wear resistance and thermal shock stability of the materials, extend the service life, and improve the wear resistance of the castables to reduce the critical particle size. From the original 8mm to 3mm, the bonding ability of the material matrix was improved. The results show that the preparation of multi-stage micro powder and super micro powder is the most compact, which is beneficial to the sintering trend at medium temperature.
