Research and development of tundish auto-casting technology for slab casters of WISCO

Based on the equipment of continuous casting plant of the 4th Sub-Works of the General Steelmaking Plant of WISCO the technology processes of auto-casting,start-up and control of the withdrawal straightening stands and auto-control of the liquid level of mould by stopper system under the condition of flow control by the stopper system were introduced.The critical function of mould level controlling was emphasized as well.Through repetitive test and application several problems were solved in the industrial producing process and as the results the auto casting rate of the works rises steadily from original 39 % to 98 % monthly on average.
