This is the continuation and expansion of our previous Collaborative Research Development projects "CRDPJ 412640-11" and "CRDPJ 381693-09" for the development of thermodynamic databases for the steelmaking de-phosphorization process and mold fluxes. The demand for high alloy high strength steels is increasing to reduce the weight of automobiles. In order to understand the complex chemical reactions between the slag, metal, refractories, inclusions, mold flux and gases during the production of high alloy steels, accurate thermodynamic knowledge of related systems is a necessary prerequisite. In this new 3-year project, the thermodynamic database developed from the two previous CRD projects will be expanded to include ZrO2, TiOx, VOx, B2O3, MnO and CrOx to the CaO-SiO2-MgO-Al2O3-FeO-Fe2O3-Na2O-K2O-Li2O-(F) system. In addition, the liquid steel database will be expanded to high alloy systems in order to deal with refining impurities like O, N, S, P, and C during the steelmaking process. To apply the thermodynamic databases to industrial processes, a simple process simulation model will be developed for each step of the secondary steelmaking process. This project will be carried out in collaboration with our previous and new partners (three Canadian partners: Rio Tinto-QIT, Nucor Steel, and RHI, and 6 non-Canadian partners: Posco, Hyundai Steel, Nippon Steel and Sumitomo Metals Corp., JFE Steel, Voestalpine and Tata Steel). The industrial partners will evaluate and provide feedback on the thermodynamic database and process model. In addition, they will also provide valuable in-house process data or operation knowledge for process simulation model developments. Results of the project will be used to improve the industrial steelmaking process for conventional and new high alloy steels. At a larger scale, this study will be useful to general pyrometallurgy, cement, glassmaking and combustion industries as well as to the geological community.

这是我们之前合作研究开发项目“CRDPJ 412640-11”和“CRDPJ 381693-09”的延续和扩展，用于开发炼钢脱磷工艺和保护渣的热力学数据库。为了减轻汽车的重量，对高合金高强度钢的需求正在增加。为了了解高合金钢生产过程中渣、金属、耐火材料、夹杂物、保护渣和气体之间复杂的化学反应，对相关系统准确的热力学知识是必要的前提。在这个新的3年项目中，从先前的两个CRD项目开发的热力学数据库将扩展到包括ZrO 2、TiOx、VOx、B2 O3、MnO和CrOx到CaO-SiO2-MgO-Al 2 O3-FeO-Fe 2 O3-Na 2 O-K2 O-Li 2 O-（F）系统。此外，钢水数据库将扩展到高合金系统，以处理炼钢过程中的O、N、S、P和C等精炼杂质。为了将热力学数据库应用于工业过程，将为炉外炼钢过程的每个步骤开发一个简单的过程模拟模型。该项目将与我们以前和新的合作伙伴（三个加拿大合作伙伴：Rio Tinto QIT，Nucor Steel和RHI，以及六个非加拿大合作伙伴：Posco，Hyundai Steel，Nippon Steel和Sumitomo Metals Corp.，JFE Steel、Voestalpine和Tata Steel）。工业合作伙伴将对热力学数据库和过程模型进行评估并提供反馈。此外，他们还将为过程模拟模型开发提供有价值的内部过程数据或操作知识。该项目的成果将用于改进传统和新型高合金钢的工业炼钢工艺。在更大的范围内，这项研究将有助于一般火法冶金，水泥，玻璃制造和燃烧工业以及地质界。
