摘要
对H型钢超快速冷却设备作了简要介绍.通过基础自动化中信号传递和液压缸的协同工作,使超快冷系统能适应不同规格H型钢的冷却要求.根据钢种开发及生产工艺要求,针对超快速冷却过程,建立了空冷和水冷温降模型.通过模块化设计,实现了过程温度的控制;通过模型自学习,使超快速冷却工艺逐步合理.从运行情况来看,腹板和翼缘温度差值可以降至30℃,协同工作的两个液压缸中磁尺数值大致吻合,从而使超快速冷却系统具有良好的可控性以及高精度和低故障率.
Ultra-fast cooling （UFC） equipment for H-beam steel is outlined. The UFC system can be adapted for the cooling requirements of H-beams with different specifications through the signal transfer in basic automation and the co-operation of hydraulic cylinders. Based on the development of H-beams and the requirements of UFC process, the temperature-drop models of water/air cooling were established, and the temperature control was achieved by modular design. The UFC process became reasonable gradually through the self-learning of the models. Operation results showed that the temperature difference between web and flange can be reduced to 30 ＂C, and the readings of magnetic feet on the two hydraulic cylinders are broadly in line, thus the UFC system is controllable, precise and reliable.
