针对某钢厂1号方坯连铸机的高效化改造,采用方坯连铸二维传热模型对其连铸过程进行了二冷仿真研究。为进一步提高仿真运算的精度以及二冷设计的准确性,对传热数学模型作出了一定的改进措施。二冷仿真设计结果已投入到实际的生产过程中,从反馈信息看,现场废品率已明显减少,铸坯质量得到了明显的改善,且产量也有大幅提升,说明针对方坯连铸二冷仿真模型采用的改进措施提高了仿真设计精度,对于铸坯质量和产量的保证是比较有利的。
Aiming at the high-efficiency transformation of No.1 billet caster in a steel mill, the second-order cooling simulation of its continuous casting process was carried out by using the two-dimensional heat transfer model of billet continuous casting. In order to further improve the precision of the simulation and the accuracy of the second cooling design, some improvements are made to the mathematical model of heat transfer. Second cooling simulation design results have been put into the actual production process, from the feedback information, the on-site scrap rate has been significantly reduced, the slab quality has been significantly improved, and the yield has also been significantly improved, indicating the second continuous casting billet simulation The improvement measures adopted by the model improve the accuracy of the simulation design and are more favorable for the guarantee of the slab quality and output.
