Refractory Materials for Iron

Refractory materials for iron making are mainly divided into sintering, blast furnace, iron field, molten iron bale and refractory materials for pretreatment. Refractories for blast furnaces and sintering machines belong to refractories for capital construction. But the molten iron bag, the iron field and the molten iron pretreatment are consumable refractory materials. Infrastructure kilns are mainly measured by their service life, while in places where refractories are consumed continuously, in addition to their service life, the quality and use level of the materials should also be measured by their single consumption. In iron - making systems, slag is characterized by neutral and acidic slag, and slag is less oxidizing. According to the selection rule of similar materials and inertias to erosion medium, the neutral refractory containing non-oxide should be selected, that is, the area should be containing silicon carbide, silicon nitrite, carbon and other aluminum-Silicon series refractory, such as aluminum-silicon series refractory, Al2O3-SIC -C material.
