Features of refractory prefabricated parts: 1. Can meet the needs of high-temperature industrial kilns. The parts to be constructed cannot be constructed with refractory bricks and castables, and prefabricated parts can be used. 2. When refractory bricks cannot be made due to factors such as weight, volume, size, etc. of the construction site, refractory prefabricated parts can be used. 3. The refractory prefabricated parts are integrally cast with refractory castables specially formulated according to customer requirements. They have the advantages of high temperature resistance, corrosion resistance, wear resistance, high strength, and good thermal shock stability. They can fully meet the use environment and conditions required by customers.
