以中冶京诚工程技术有限公司为江西九钢3 500 mm轧板厂开发的中厚板层流冷却过程控制系统为例,介绍了该过程控制系统的架构、冷却模型的组成、冷却策略、冷却规程计算方法和均匀性控制策略、系统界面以及实际应用效果。生产应用表明,该系统终冷温度控制精度达到±20℃,纵向温差小于30℃,各项指标达到了国外同类产品的水平,具有进一步推广应用的价值。
Taking MCC Jingcheng Engineering Technology Co., Ltd. As the control system of laminar flow cooling in medium and heavy plate developed by Jiangxi Jiu Steel 3 500 mm rolling mill as an example, the structure of the process control system, the composition of cooling model, the cooling strategy, Cooling procedure calculation method and uniformity control strategy, system interface and practical application results. The production application shows that the precision of this system is ± 20 ℃ and the longitudinal temperature difference is less than 30 ℃. The indexes have reached the level of similar foreign products and have the value of further popularization and application.
