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.

Abstract: 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.
