Tata Steel is one of the leading global suppliers of automotive steel products and one of the future challenges will be to produce steels with good formability for use in body in white applications. Currently this is done using ultra low carbon (ULC) interstitial free (IF) steels. IF steels allow automotive manufactures to produce aesthetically pleasing designs but one of the current challenges facing the steel industry is the need to decarbonise and utilise increasing levels of recycled steel. In order to meet these challenges various options will need to be explored. One option being considered by a number of European steelmakers, is to convert to electric arc furnace (EAF) steelmaking. For a range of specifications, EAF provides minimal challenges for switching from basic oxygen steelmaking. We believe IF steels will present a challenge due to the need for low carbon and low nitrogen levels not typically seen from EAF process routes. It is hoped that this project will develop knowledge in this field and the Research Engineer will accomplish the following objectives: - Understand capability of EAF to produce low carbon and low nitrogen levels. Evaluate options to produce high formability steel specifications (DX56+Z/DX57+Z) via the EAF route. Proposed Activities:- Understand capability of EAF steel making especially with regards to producing interstitial free steel.- Evaluate impact of steel cleanliness compared to BOF/RH route.- Evaluate feasible levels of interstitial free elements and create lab casts to simulate (VIM).- Develop lab-based processing route and evaluate mechanical properties (CASIM).- Evaluate suitability for hot dip galvanising (HDSIM).- Provide recommendations for future capability and process routes.

塔塔钢铁是全球领先的汽车钢材供应商之一，未来的挑战之一将是生产具有良好成形性的钢材，用于白色应用中。目前，这是使用超低碳（ULC）无间隙（IF）钢来完成的。IF钢允许汽车制造商生产美观的设计，但钢铁行业目前面临的挑战之一是需要脱碳和利用越来越多的再生钢。为了应对这些挑战，需要探讨各种备选办法。许多欧洲钢铁制造商正在考虑的一种选择是改用电弧炉（EAF）炼钢。对于一系列规格，EAF为从碱性氧气炼钢切换提供了最小的挑战。我们认为IF钢将面临挑战，因为需要低碳和低氮水平，而这在EAF工艺路线中并不常见。希望该项目将发展该领域的知识，研究工程师将实现以下目标：-了解电弧炉生产低碳和低氮水平的能力。评估通过电弧炉生产高成形性钢规格（DX 56 +Z/DX 57 +Z）的方案。建议的活动：-了解电弧炉炼钢的能力，特别是关于生产无间隙原子钢。与BOF/RH工艺路线相比，评估钢洁净度的影响。评估无间隙元素的可行水平，并创建实验室铸件进行模拟（Vim）。开发基于实验室的加工路线并评估机械性能（CASIM）。评估热浸镀锌（HDSIM）的适用性。为未来的能力和工艺路线提供建议。
