Abstract

Although it is an old technique, research on the hot rolling process maintains its importance because of its widespread usage in steel production and its requirement for a vast amount of resources, especially energy. The roll pass design of the hot rolling process considerably affects many operational parameters such as energy requirement, wear of the rolls, working forces, and torques. Furthermore, due to the sequential nature of the rolling process, a design of any number of passes is strictly interrelated with all other passes in the process. This makes it very involved to find optimum design solutions that allow for the compromise between conflicting goals and restrictions. In this paper, a new optimized solution search strategy based on a desirability function is offered to deal with the sequential characteristics of the roll pass design. A novel optimization method utilizing response surfaces and the proposed solution search strategy is presented to reduce the shaping energy of the overall process while minimizing turning moments and radial forces on rolls during the rough rolling process. The method and solution search strategy developed are illustrated and validated via a case study. Comparing the case study's findings to three distinct pass designs used in industrial power plants, it was discovered that significant energy savings, low turning moments, and reduced radial forces had been made compared to the reference designs.

基于可取性的热轧过程序贯优化解搜索方法
尽管热轧工艺是一项古老的技术,但由于其在钢铁生产中的广泛应用以及对大量资源,特别是能源的需求,热轧工艺的研究仍然具有重要意义。热轧过程的孔型设计对许多操作参数有很大影响,如能量需求、轧辊磨损、工作力和扭矩。此外,由于轧制过程的顺序性,任何道次的设计都与该过程中的所有其他道次严格相关。这使得它非常需要找到最佳设计解决方案,以便在相互冲突的目标和限制之间达成妥协。针对孔型设计的时序性特点,提出了一种基于期望函数的优化求解策略。提出了一种利用响应曲面和所提出的求解搜索策略的新优化方法,以减少整个过程的成形能量,同时最大限度地减少粗轧过程中对轧辊的转动力矩和径向力。通过案例研究,对所开发的方法和解决方案搜索策略进行了说明和验证。将案例研究的结果与工业发电厂中使用的三种不同的孔型设计进行比较,发现与参考设计相比,显著节省了能源,降低了转动力矩,并减少了径向力。
