Fundamentals of Metal Processing and Casting Operations

这笔发现基金的主要目的是促进我们对以下方面的认识：1)如何提高钢液的内在质量(通过50微米以下较小夹杂物的较低浓度来衡量)，以显著改善钢的一般性能；2)如何开发一种比目前的钢板生产技术更好的铸钢方法。它使用机器连续浇铸厚(350 Mm)或薄(60 Mm)的板坯，然后使用板坯再加热炉，以及六个或七个热轧机架，最终生产热轧卷板。新的近终形铸造(NNSC)技术是近20年前提出的，对于生产新的、先进的高强度、高塑性(HSHD)钢来说是至关重要的，用于交通行业。这些先进钢采用TRIP[相变诱发塑性]和TWIP[孪生诱发塑性]强化机制，具有较高的锰(~30%)和铝(~7%)含量。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
