铁前系统的成本决定着钢铁企业成本的走向,降低铁前生铁制造成本是钢铁企业降本增效的重中之重。1、界定物料综合成本,为采购确定导向。精料是铁前系统努力方向,但铁前系统应测算物料成本与生铁制造成本的盈亏平衡点,优化 The cost of the pre-iron system determines the trend of the cost of the iron and steel enterprises. Reducing the manufacturing cost of the iron before the iron is the most important factor in reducing costs and increasing efficiency of the steel enterprises. 1, define the overall cost of materials, to determine the direction for the procurement. Concentrate is the direction of the system before the iron, but the iron system should be measured before the cost of raw materials and pig iron manufacturing cost break-even point, optimization
