1. Introduction The application of Q-BOP and various top and bottom compound blowing processes can improve the refining effect of LD top-blown oxygen converter. However, when blowing high-phosphorus hot metal, many problems have not been solved because of the large amount of slag. At the same time to produce low-phosphorus steel and increase the tapping temperature to increase
