Abstract:ased upon the practice of hot metal predesulphurization at Baosteel, the production results, powder consumption,omanagement of production and economic benefits of several processes are analyzed.It was shown that for selection of resonable method of hot metal predesulfurization the raw material availability, layout of equipment, matching of hot metal and steel production,target of pretreatment,cost and so on must be considered. The best mode of hot metal predesulfurization at Baosteel is the predesulphurization in hot metal ladle, which has following merits:short treatment time, low powder consumption, final sulfur content and treatment cost. So it is a high efficiency predesulfurization technology and is good for popularization.
