Corundum silicon carbide slide brick refers to the refractory brick used for the slide of steel rolling heating furnace, which is mainly produced with fused brown corundum and silicon carbide as the main raw materials. It is mainly in the temperature range of 800 ℃ - 1450 ℃. It can improve the billet heating quality, improve the steel quality, increase the heating furnace pad efficiency by about twice, reduce the fuel consumption by 20%, increase the heating capacity by 30%, and the service life is more than 12 months.
Corundum silicon carbide slide brick has high high temperature strength, good wear resistance, good thermal conductivity, excellent thermal shock resistance and strong corrosion resistance to iron oxide slag. The main indicators of the product are as follows
Al2O3 % | SiC % | Fe2O3 % | Apparent porosity % | Normal temperature compressive strength Mpa | Load softening temperature ℃ |
≥79 | 14 | ≤0.8 | ≤15 | ≥75 | ≥1600 |
