Resumo
The free opening rate of the steel ladle not only affects the efficiency of steel production due to reduced casting speed, process interruptions and the production of non-clean steel, but also exposes the operators a personal accident, which has a great impact on the cost and quality of the steel produced. In this study, two chromite-based filler sands were analyzed and the free opening rate was evaluated by considering the effect of chromite sand concentration in the filler sand. The higher content of chromite in the filler sand changed the sintering behavior of the filler sand and improved the free opening rate of in 0.45%.
