Research of BOF Protection Technology by Slag Splashing

Abstract:

Based on the application of slag splashing for building up a protective coating layer on the refractory lining, a technique for comprehensive maintenance of converter refractory linings has been developed in this paper. The effect of slag properties, slag amount, tapping temperature, and lance height on the splashing was investigated by physical model experiments. The facilities and regimes of 50-ton converter at the Long-steel had been modified. At present, the life of converter lining has already reached to 15,000 heats, the productivity reached 87 %.
