The primary aim of this discovery grant is to advance our knowledge on 1) how to improve the intrinsic quality of liquid steel (as measured by lower concentrations of smaller inclusions below 50 microns), in order to significantly improve the general properties of steels, and 2) how to develop a better way to cast steels versus the current technology for steel sheet production. This uses machines to continuously cast thick (350 mm), or thin (60 mm), slabs, followed by slab reheat furnaces, and six, or seven, stands of hot rolling mills, to finally produce hot rolled coils. The new Near Net Shape Casting (NNSC) technology, proposed some twenty years ago, is vital for the production of new, advanced high strength, high ductility (HSHD) steels for the transportation sector. These advanced steels are high in manganese (~30%) and aluminum (~7%), using TRIP [transformation induced plasticity] and TWIP [Twinning induced plasticity] strengthening mechanisms. Such steel grades are beyond the capabilities of the current technology, but can triple the strength and quintuple elongations of conventional steels! Given these attributes, one can "lightweight" automobile and truck bodies, very significantly. To meet these objectives, we have unique equipment at hand, on which our graduate students can perform their experimental research; a full scale water model of a typical ladle-tundish-mold facility, and a large, pilot scale, Horizontal Single Belt Caster (HSBC), together with appropriate induction furnaces plus various resistance furnaces operating between 1000 C and 1800 C. These will be used in conjunction with our high performance SGI computer cluster, also at our Stinson Laboratory, as well as smaller ancillary equipment, so that we can formulate, and experimentally verify, various research strategies, and plan associated follow-up research projects, to accomplish these objectives. It will simultaneously lead to the training of High Quality Personnel, specialized in both the practical and theoretical aspects of Process Metallurgical Engineering. This HSBC casting research is also of great relevance to the aluminum industry. Thus, over the next five year granting period, we expect to graduate a total of about ten doctoral students for industry, academia, and government. Whilst Canada presently has strong steel and aluminum companies, and well trained engineers, University Researchers must help this situation by continuing to produce graduates trained and familiar with leading edge advances in technologies of relevance to these industries. Cleaner steels and HSBC casting are two such areas of great importance in the future of steelmaking, where the MMPC is working in collaboration with QIT (Quebec Iron and Titanium) of RTIT, with AMD (Dofasco) and HATCH, as well as its other globally dispersed companies that have supported us, to help effect these transformations.*** **

这项发现资助的主要目的是增进我们对以下方面的认识：1）如何提高钢水的内在质量（通过低于 50 微米的较小夹杂物的较低浓度来衡量），以显着提高钢的一般性能，以及2) 如何开发一种与当前钢板生产技术相比更好的铸钢方法，该方法使用机器连续铸造厚板坯（350 毫米）或薄板坯（60 毫米），然后使用板坯再热炉，以及六台，或七个，大约二十年前提出的新近净成形铸造 (NNSC) 技术对于生产新型先进高强度、高延展性 (HSHD) 钢材至关重要。这些先进钢的锰含量 (~30%) 和铝含量 (~7%) 高，使用 TRIP [相变诱导塑性] 和 TWIP [孪生诱导塑性] 强化机制超出了此类钢种的能力。凭借当前技术的优势，强度和伸长率可以达到传统钢材的三倍！鉴于这些特性，我们可以非常显着地“轻量化”汽车和卡车车身，以实现这些目标，我们拥有独特的设备，我们的毕业生可以使用这些设备。学生可以进行实验研究；典型的钢包中间包结晶器设施的全尺寸水模型，以及大型中试水平单带连铸机（HSBC），以及适当的感应炉以及在其之间运行的各种电阻炉。 1000 C 和 1800 C。这些将与我们的高性能 SGI 计算机集群（也在我们的 Stinson 实验室）以及较小的辅助设备结合使用，以便我们可以制定、并通过实验验证、研究各种策略并规划相关的后续研究项目，以实现这些目标，同时将培养专门从事工艺冶金工程实践和理论方面的高素质人才。汇丰铸造研究也与此密切相关。因此，在未来五年的资助期内，我们预计将为工业界、学术界和政府部门培养大约十名博士生，而加拿大目前拥有强大的钢​​铁和铝业公司以及训练有素的工程师和大学研究人员。清洁钢材和汇丰铸造是未来炼钢业中非常重要的两个领域，MMPC 正在与这两个领域合作。 QIT（魁北克RTIT 的铁和钛）与 AMD (Dofasco) 和 HATCH 以及其他支持我们的全球分散公司一起帮助实现这些转型。*** **
