为了摆脱“取-造-弃”的经济，有一种重新使用和回收材料的动力。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期望的残留物，这对所生产的钢的质量具有后果。在这项工作中，英国钢铁行业利用国家废钢库存，以满足英国的钢铁需求的影响，探讨通过迭代生产模型。从汇编的文献数据中获得废料质量和体积，以生成可靠的原料。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留物富集。结果发现，在目前的工艺和产品规格下，英国可以可持续地向高炉-转炉/电炉之间50/50的生产分工过渡。这一转变将使英国钢铁行业的排放量减少20%。
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%.
