项目摘要
Micro-alloyed steels are very cost-effective steels for a wide range of applications where improved mechanical properties, namely strength, hardness, creep and toughness, are desired. Careful control of the chemistry of the steel, coupled with controlled processing of the slabs through hot working and cold forming result in achieving the desired properties for microalloyed steels. Typically, these properties are achieved metallurgically in thermomechanical processing through a combination of grain refinement, solute strengthening and precipitation hardening. One of the key operations in achieving these properties is on the run out table (ROT). Here the strip steel is cooled after the last rolling pass to achieve the desired microstructure and properties of the skelp. Recent advances in modeling the heat losses on the ROT and the CCT diagram provides the opportunity to further enhance and control the finished microstructure and properties as well as the homogeneity and consistency of the product from the start of a coil to its end. In this project, we aim to further validate this combined heat transfer-microstructure evolution model for the ROT using different grades of pipeline microalloyed steels. This project will involve the carrying out of plant trials, coupled with the generation of CCT Diagrams for the steels, mathematical modeling of the heat loss from the skelp coupled with the steel transformation. Two Graduate Students per year will be trained in this 4 year project. The fundamental understanding of the fabrication, microstructure, properties and performance of these higher strength microalloyed steel grades for pipeline applications will have significant socio-economic benefits to Canada.
微合金钢是非常具有成本效益的钢,用于需要改善机械性能,即强度、硬度、蠕变和韧性的广泛应用。 仔细控制钢的化学成分,再加上通过热加工和冷成形对板坯进行控制加工,可以实现微合金钢的所需性能。 通常,这些性能是在热机械加工中通过晶粒细化、溶质强化和沉淀硬化的组合以热塑性方式实现的。 实现这些性能的关键操作之一是在运行表(ROT)上。 在这里,带钢在最后一个轧制道次之后被冷却,以获得所需的微结构和性能。 在ROT和CCT图上建模热损失的最新进展提供了进一步增强和控制成品微观结构和性能以及产品从线圈开始到结束的均匀性和一致性的机会。 在这个项目中,我们的目标是进一步验证这一组合传热组织演变模型的ROT使用不同等级的管线微合金钢。 该项目将涉及进行工厂试验,再加上生成的CCT图的钢,数学建模的热损失从耦合到钢的转变。 每年有两名研究生将在这个为期4年的项目中接受培训。 对这些用于管道应用的高强度微合金钢的制造、微观结构、性能和性能的基本了解将对加拿大产生重大的社会经济效益。
