Abstract: An analysis on various factors to influence 80 t ladle sliding nozzle free-opening rate is carried out. Combined with the situation of steelmaking plant at Xiang Steel, by adopting measures including increasing quality of initiate packing sand and improving its adding method, improving base brick and upper nozzle structure, and decreasing waiting time of liquid for casting, the ladle free-opening rate at steelmaking plant increases to 96. 2% from original 84.3%.
