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。这种钢种超出了当前技术的能力，但可以

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
