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.*** **

这项发现基金的主要目的是推进我们的知识：1)如何提高钢液的内在质量（通过低于50微米的较小夹杂物的较低浓度来测量），以显着改善钢的一般性能；2)如何开发一种更好的铸钢方法，而不是目前的钢板生产技术。它使用机器连续铸造厚（350毫米）或薄（60毫米）的板坯，然后是板坯再加热炉和六台或七台热轧机，最后生产热轧卷板。近净形铸造（NNSC）技术是20多年前提出的，它对交通运输行业生产新型、先进的高强度、高塑性（HSHD）钢至关重要。这些高级钢含有高锰（~30%）和高铝（~7%），采用TRIP（相变诱发塑性）和TWIP（孪生诱发塑性）强化机制。这样的钢种超出了当前技术的能力，但它的强度是传统钢的三倍，延伸率是传统钢的五倍！鉴于这些属性，人们可以“轻量化”汽车和卡车的车身，非常显著。为了实现这些目标，我们手头有独特的设备，我们的研究生可以在上面进行实验研究；一个典型的钢包-中间包-模具设施的全尺寸水模型，一个大型的中试规模水平单带连铸机（HSBC），以及适当的感应炉和各种运行在1000摄氏度到1800摄氏度之间的电阻炉。这些将与我们高性能的SGI计算机集群（也在我们的斯廷森实验室）以及较小的辅助设备一起使用，以便我们可以制定并实验验证各种研究策略。并计划相关的后续研究项目，以实现这些目标。它将同时导致高质量的人才培训，专门在实践和理论方面的过程冶金工程。这项汇丰铸造研究对铝工业也有很大的相关性。因此，在未来五年的资助期内，我们预计将为工业界、学术界和政府培养大约10名博士生。虽然加拿大目前拥有强大的钢铁和铝公司以及训练有素的工程师，但大学研究人员必须通过继续培养训练有素并熟悉这些行业相关技术前沿进展的毕业生来帮助这种情况。清洁钢和汇丰铸造是未来钢铁制造的两个非常重要的领域，MMPC正在与RTIT的QIT（魁北克铁钛），AMD （Dofasco）和HATCH以及其他支持我们的全球分散公司合作，以帮助实现这些转型。* * * * *
