项目摘要
The development of new steel products continues to play an important role in the economy and society. The ever increasing pace of steel development is driven by the demands of critical sectors like automobile manufacturing, construction and energy. Developing new steels requires to deepen the knowledge in the underlying metallurgy and constant modernization of steel production facilities. Accelerated cooling has become a key technology to produce thermo-mechanically controlled processed hot-rolled steels with fine grained and/or multi-phase microstructures and the mechanical properties that are now increasingly required for demanding applications. Using well-designed processing paths rather than alloying additions is an attractive approach to manufacture these high-performance steels. The cooling path on the runout table takes a critical role as it can be used to tailor the phase transformation from austenite with a face-centred cubic (FCC) crystal structure to ferrite with a body-centred cubic (BCC) crystal structure. In detail, depending on steel chemistry and processing path, different transformation products can be obtained to create complex multi-phase microstructures which offer new paradigms for the design of properties. The Canadian steel industry, including ArcelorMittal Dofasco (AMD), is actively engaged in upgrading their runout table cooling capabilities. A particular challenge is here the production of thicker gage steels, e.g. line pipe, because the intense cooling, e.g. in a pressurized spray unit, may lead to through-thickness microstructure/property variations. The development of process models will have an increasing impact for making these value-added products with high quality and minimum variability. The proposed project is conductecd in collaboration with AMD to develop a next generation runout table model that combines heat transfer and phase transformation kinetics for line pipe steels. Experimental studies will be carried out on a pilot scale runout table facility and the thermo-mechanical processing laboratory to provide guidance for the model development. The proposed model will be validated with industrial data. The project offers training opportunities for three graduate students.
钢铁新产品的开发继续在经济和社会中发挥重要作用。钢铁发展的步伐不断加快是由汽车制造、建筑和能源等关键行业的需求推动的。开发新的钢材需要加深基础冶金知识和钢铁生产设施的不断现代化。加速冷却已经成为生产具有细晶粒和/或多相显微组织以及现在对苛刻应用越来越要求的机械性能的热机械控制加工的热轧钢的关键技术。使用精心设计的加工路径而不是合金添加剂是制造这些高性能钢的一种有吸引力的方法。输出台上的冷却路径起着关键作用,因为它可用于定制从面心立方(FCC)晶体结构的奥氏体到体心立方(BCC)晶体结构的铁素体的相变。具体而言,根据钢的化学成分和加工路径,可以获得不同的转变产物,以创建复杂的多相微观结构,为性能设计提供新的范例。包括ArcelorMittal Dofasco(AMD)在内的加拿大钢铁行业正在积极升级其热轧板冷却能力。这里的一个特殊挑战是生产较厚规格的钢,例如管线管,因为例如在加压喷射单元中的强烈冷却可能导致全厚度显微组织/性能变化。工艺模型的开发将对制造高质量和最小可变性的增值产品产生越来越大的影响。该项目将与AMD合作开发下一代跳动表模型,该模型结合了管线钢的传热和相变动力学。实验研究将在中试规模的跳动表设施和热机械加工实验室进行,为模型开发提供指导。该模型将与工业数据进行验证。 该项目为三名研究生提供了培训机会。
