ABSTRACT To move away from the ‘take-make-dispose’ economy there is a drive to reuse and recycle materials. For the steel industry this means using more steel scrap. This has a consequence on the quality of the steel produced due to the presence of undesirable residuals from steel scrap. In this work, the effect of the UK steel industry utilising national scrap stocks to meet the UK demand for steel is explored through an iterative production model. Scrap qualities and volumes were obtained from compiled literature data to generate a reliable feed stock of material. The scrap feed is considered in the BF-BOF and EAF production routes to model the enrichment of residuals through cycles of the materials use. It was found that with current process and product specification the UK could sustainably migrate towards a 50/50 production split between BF-BOF/EAF. This shift would reduce the UK’s steel industry emissions by ~20%.

模拟英国循环钢铁行业中废钢使用的累积效应——残余元素聚合

摘要 为了摆脱“获取-制造-处置”经济，需要再利用和回收材料。对于钢铁行业来说，这意味着使用更多的废钢。由于存在来自废钢的不希望的残余物，这对所生产的钢的质量有影响。在这项工作中，通过迭代生产模型探索了英国钢铁行业利用国家废料库存满足英国钢铁需求的效果。从汇编的文献数据中获得废料质量和体积，以生成可靠的材料原料。在 BF-BOF 和 EAF 生产路线中考虑废料进料，以模拟通过材料使用循环的残余物富集。结果发现，根据当前的工艺和产品规格，英国可以可持续地向高炉转炉/电弧炉之间的 50/50 生产分配过渡。这一转变将使英国钢铁行业的排放量减少约 20%。
