Induction furnace lining material
Mgo | Al2O3 | Cr2O3 | SiO2 | Fe2O3 | Cao | |
Neutral | ≥9 | ≥85 | ≤1 | ≤1 | ≤0.5 | ≤1 |
Acid | ≤3 | ≤1 | ≥85 | ≤1 | ≤1 | |
Basic | ≥70 | ≥16 | ≤1 | ≤3 | ≤1 | ≤2 |
Remark:
1. High manganese steel and stainless steel can be used in over 100 heats on basic lining material.
2. If large furnace, we can suggest that you use neutral materials.More heats , high safety factor, and high cleanliness of molten steel produced (i.e. good composition of molten steel)
