Fundamentals of Metal Processing and Casting Operations

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
