摘　　要：研究了珠钢150 t Fuchs竖式电弧炉的各种钢铁料及布料方式对电耗、冶炼周期和冶金质量的影响。结果表明,配料时必须参照生铁、海绵铁最大加入量、上下工序产能匹配、产品中残余元素的控制、冶炼指标等要求,在质量、成本、效率等方面寻求一合理的平衡点。为加速熔化,在第一篮料的下部适当多装一些生铁和/或较优质的废钢;在最后一篮料的上部装一些质量较好的废钢,下压轻薄废钢避免结团挂料,上部不可装入过多生铁,避免化清后碳太高而导致冶炼时间延长。The effect of grade of iron and steel scrap and charge matching mode on electric power consumption, tap to tap time and metallurgical quality of an 150 t Fuchs shaft furnace at Zhusteel. Results show that the requirements of max adding amount of pig iron and sponge iron, match of capacity of up and down procedure, control of residual elements in products and steelmaking indexes must be consulted in mixture charging process to get a reasonable balance in terms of quality, cost and efficiency. To speed scrap melting, it is available to add more pig iron and/or quality scrap at bottom of first basket, and charge a number of quality scrap at top of final basket above light and thin scrap to avoid the scrap knot while the overburden of pig iron is not available at top to avoid over carbon content in liquid led to prolonging tap to tap time.
