Under the background of the Chongqing Iron and Steel Group New Iron and Steel one ladle systemprocess,this thesis elaborates the problem of molten iron settlement between iron and steel mills. According to the life cycle of molten iron tank and molten iron metering process,combining with molten iron field statue,we designed the molten iron settlement algorithm ultimately. The accurate and efficient algorithm,which achieves the sharing of data within the enterprise,plays an important role in the cost account...
