Fundamentals of Metal Processing and Casting Operations

这项发现补助金的主要目的是提高我们在以下方面的知识：1）如何提高钢水的内在质量（通过降低50微米以下较小夹杂物的浓度来衡量），以显着提高钢的一般性能，以及2）如何开发一种更好的方法来铸造钢与当前的钢板生产技术。这使用机器连续铸造厚（350 mm）或薄（60 mm）板坯，随后通过板坯再加热炉和六个或七个热轧米尔斯机架，以最终生产热轧卷。近净形铸造（NNSC）新技术在大约20年前提出，对于生产用于运输行业的新型先进高强度、高延展性（HSHD）钢至关重要。这些先进的钢是高锰（~30%）和铝（~7%），使用TRIP [相变诱导塑性]和TTRIP [孪生诱导塑性]强化机制。这种钢种超出了现有技术的能力，但可以使传统钢的强度增加三倍，伸长率增加五倍！鉴于这些属性，人们可以“轻量化”汽车和卡车车身，非常显着。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-连铸-结晶器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电阻炉，在1000 C和1800 C之间运行。这些将与我们的高性能SGI计算机集群一起使用，也在我们的Stinson实验室，以及较小的辅助设备，这样我们就可以制定和实验验证，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。它将同时导致高素质人才的培养，专门从事过程冶金工程的实践和理论方面。汇丰的这项铸造研究也与铝行业有很大的相关性。因此，在未来五年的资助期内，我们预计将为工业界、学术界和政府部门培养约十名博士生。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受过培训并熟悉与这些行业相关的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炼钢领域中两个非常重要的领域，MMPC正在与RTIT的QIT（魁北克铁和钛），AMD（Dofasco）和HATCH以及其他支持我们的全球公司合作，以帮助实现这些转型。**

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.*** **
