Key Competitive DriverThe largest technical challenge approaching Tata Steel UK in the next 20 years is to decarbonise product. 80% of CO2 in steel production is generated in the process steps leading up to casting. The current process technology portfolio has overall similarities to others internationally which achieve up to 20% lower carbon emission production than the average at port-talbot due to the incorporation of high proportions of ferrous scrap both in the BF and BOF.This project aims to add to the body of investigations developing knowledge on the potential of higher ferrous scrap proportion use now, through transition periods and into potential future steel production conditions for the business.Although aspects such as residual levels will become critical factors in the application of scrap in the production of strip steels, the current control factors which limit scrap usage on a daily basis in PT are:1. Reaching tapping temperature (1o average gain = £#.##/t/a)2. Maintaining quality of steel within the BOF - process control such as slag properties and steel cleanness (Al, Si, P and S contamination)3. Time taken for scrap to melt (Size, shape and packing)PT is investing in a new scrap pre-heating lance which will enable use of increased scrap volume in the BOF, however this has the potential to have several negative impacts including increased in process time, high levels of scrap oxidation in the vessel, and the formation of intermediate scrap skulls which may impact melting times negatively. With this in mind this project intends to focus on the potential of scrap usage for BOF process stability in order to maximize gain of the heating lance instalment and limit potential negative impacts. In addition, this specific institute is chosen to deliver the project due to the expertise of identified personal, synergistic activities such as SUSTAIN, I-space, TFI-Demo, SWITCH...etc, the locality of training increasing likely hood to inhouse newly skilled personal and the leverage of funding from EMR to fund a synergistic studentship exploring fundamental questions for the application of scrap in EAF processing.Objectives:1. To understand the composition of strategic high volume scrap grades such as heavy basic and incinerator scrap 2. To re-asses the effect of scrap composition on BOF temp after interaction with the pre-treatment lance.3. Develop understanding for scrap basket mix importance under variable load volumes and with/without pre-heating4. To inform the steelmaking VIU model as to the better application of scrap grades under new working conditions of pre-heating and high scrap volume use in the steelmaking process.

关键竞争驱动力 塔塔钢铁英国公司未来 20 年面临的最大技术挑战是脱碳，钢铁生产中 80% 的二氧化碳是在铸造过程中产生的。目前的工艺技术组合与国际上其他工艺技术组合总体相似。由于高炉和转炉中含有高比例的黑色金属废料，塔尔伯特港的碳排放产量比平均水平低 20%。该项目旨在增加研究主体，开发有关碳排放的知识现在、过渡时期以及未来潜在的钢铁生产条件中使用较高黑色废钢比例的潜力。尽管残留水平等方面将成为废钢在带钢生产中应用的关键因素，但目前的控制因素PT 中每天的废钢用量限制如下： 1. 达到出钢温度（1o 平均增益 = £#.##/t/a） 2. 保持转炉内的钢材质量 - 过程控制，例如炉渣特性和钢材清洁度。 （艾尔， Si、P 和 S 污染）3. 废钢熔化所需的时间（尺寸、形状和包装）PT 正在投资一种新的废钢预热喷枪，这将能够在转炉中使用增加的废钢量，但这具有潜力。产生一些负面影响，包括加工时间增加、容器中废钢氧化程度高以及可能对熔化时间产生负面影响的中间废钢壳的形成，考虑到这一点，该项目打算重点关注废钢利用的潜力。转炉工艺稳定性为了最大限度地提高加热喷枪安装的收益并限制潜在的负面影响，由于 SUSTAIN、I-space、TFI-Demo、 SWITCH...等，培训地点增加了培训新技能人员的可能性，并利用 EMR 的资金为协同学生提供资金，探索在 EAF 中应用废料的基本问题目标：1. 了解战略性高产量废钢的成分，例如重碱废钢和焚烧炉废钢。 2. 重新评估废钢成分与预处理喷枪相互作用后对转炉温度的影响。3. 加深理解。了解可变负荷量和有/无预热情况下废钢混合的重要性4。
