Due to the working environment requirements of the glass melting furnace, the applied refractory castable should have the characteristics of good high temperature resistance, strong resistance to glass liquid erosion, and low porosity. The main refractory castable used are fused silica castable, corundum castable, and lightweight mullite önthető.
Refractory castable for iron-making systems In iron-making systems, there are many refractory castable for blast furnace tapping trenches, and ASC refractory castable are generally used. ASC castable are generally low-cement or ultra-low-cement castable, mainly composed of Al2O3 aggregates, SiC, carbon, cement and various additives.
In the application of tűzálló önthető, aluminum silicon carbide carbon castable are mainly used in the furnace bottom, molten pool and slag line. The spray gun is an important device for the pretreatment of molten iron. The spray gun refractory material has gradually developed into a castable integral pouring spray gun, and its material is mainly Al2O3-SiO2 system. The overall spray gun made of the castable has the characteristics of uniform organization, no joints, good thermal shock resistance and long service life.
