Test Study and Application of Corundum Slag in Slag-Forming of BOF

The paper introduced the process of slag-forming by using corundum slag in converter. The results showed that Al2O3 in corundum can reduce converter slag melting point, in advance of slag melting. Using this material, slagging process can be ahead of schedule for 30~40 seconds and the whole process of slag melting is good, without splashing, getting drying and lance-sticking. The consumption of metallic material and lime is reduced, and it shortens the melting period.
