Significantly increasing the use of steel scrap in steel production has become a strategic decision for the UK steel industry. This is driven by the government compulsory target of reducing CO2 emissions by 80% before 2050 for industry and is motivated by the current over-supply of steel scrap and its projected growth in quantity into the 2020's. Therefore strategies to increase the amount of scrap steel used in future steelmaking operations have attracted a good deal of research interest particularly in recent years, including significant current work within UK academia and the UK steel industry and are a key part of the discussions around sustainability, net zero and materials circularity. This is a topic that is important not only to scrap based electric arc furnace based steelmakers, but also to integrated steelmakers, who are interested in increasing the use of scrap steel in both the blast furnace (BF) process used to make iron, and the basic oxygen process (BOF) used to make steel. In addition, many integrated steel makers are already exploring the requirements for the transition to more scrap based steelmaking operations in the future.Therefore the need to understand some of the limitations and challenges, and solve some of the problems associated with the increased use of scrap will become even more crucial to the industry in the years ahead. This project would complement the current portfolio of existing scrap projects and will approach the problem using both experimental techniques and life cycle thinking methodology. The principal aims of this project are 1. To understand more about the chemical nature and physical form of existing scrap streams, and how that affects the melting behaviour, heat transfer and chargeability of the scrap2. What changes would be required to these scrap streams in terms of physical form, quality and chemistry to allow for increased use of scrap within both the BOF and BF3. How these changes might affect product design for an electric steelmaking route compared with an integrated route and what would be required for the design of steel products to make the re-use, recovery and recycling of them at end of life much easier in terms of exploitation in the steelmaking processes. 4. To carry out an environmental assessment of scenarios involving the increased use of scrap in both basic oxygen and blast furnace ironmaking operations

钢铁生产中钢废料的使用显着增加已成为英国钢铁行业的战略决定。这是由于政府强制性的目标是将二氧化碳排放量减少到2050年之前的80％的行业，并且是由于目前的钢铁废料的过度供应以及其预计将其数量增长到2020年代所激发的。因此，增加在未来的炼钢行动中使用的废钢量的策略吸引了很多研究兴趣，尤其是近年来，包括英国学术界和英国钢铁行业的当前大量​​工作，并且是围绕可持续性，净零和材料循环的讨论的关键部分。这个话题不仅对基于废料的电弧炉基于钢铁制造商，而且对集成的钢铁制造商很重要，他们有兴趣增加用于制造铁的爆炸炉（BF）工艺中的废钢的使用，以及用于制造钢的基本氧气工艺（BOF）。此外，许多钢铁制造商已经在将来探索过渡到过渡到更多基于废料的钢制造业务的要求。因此，需要了解一些局限性和挑战，并解决与SCRAP的使用相关的一些问题将在未来几年对行业变得更加重要。该项目将补充现有废料项目的当前投资组合，并将使用实验技术和生命周期思维方法来解决问题。该项目的主要目的是1。更多地了解现有废料流的化学性质和物理形式，以及如何影响SCRAP2的熔融行为，传热和费用。这些废料流对物理形式，质量和化学反应需要什么变化，以增加BOF和BF3中的废料使用。与集成路线相比，这些变化如何影响电炼钢路线的产品设计，以及设计钢产品的设计需要使重新使用，恢复和回收在生命结束时更容易在钢制过程中的剥削方面。 4。进行环境评估，涉及在基本氧气和爆炸炉熨烫操作中增加废料的使用
