由于能源成本和二氧化碳排放量的降低以及英国废钢供应充足，钢铁行业越来越强烈地希望增加高炉（BF）-碱性氧气炉（BOF）一体化路线中的废钢使用量，并扩展基于废钢的电弧炉（EAF）路线进行钢铁生产。一般来说，废钢可能含有高含量的不良残留元素，这可能对钢铁生产的铸造过程产生显着影响。本文批判性地回顾了当前冶金学对铸造过程中各种残余元素在高温（>1200°C）和低温（<1200°C）下单独和协同行为的理解，重点关注残余元素引起的局部富集和裂纹。本文旨在通过识别当前的限制和机遇，帮助钢铁界提高钢铁生产中废钢的利用率。
There is a growing drive within the steel industry to increase scrap usage in the Blast Furnace (BF)-Basic Oxygen Furnace (BOF) integrated route and extend the scrap-based Electric Arc Furnace (EAF) route for steel production due to the resultant reduced energy costs and CO2 emissions and the abundant steel scrap supply in the UK. In general, steel scrap may contain high levels of undesirable residual elements, which may have pronounced effects on the casting process of steel production. This article critically reviews current metallurgical understanding about the behaviour of various residual elements, individually and synergistically at high (>1200°C) and low (<1200°C) temperatures during the casting process, with a focus on local enrichment and cracking caused by the residual elements. This review article aims to help the steel community to increase the utilisation of steel scrap for steel production by identifying the current constraints and opportunities.
