本文简要介绍了一种由最佳加热曲线、热状态模型、出炉钢坯温降模型、最佳设定值计算组成的加热炉最佳化控制系统。在本系统的控制下,当装炉钢坯品种规格变化大或轧线出现计划、非计划生产停顿时,仍能精确控制钢坯出炉温度和温度均匀性,达到提高产量和节约能源的目的。 In this paper, a heating furnace optimization control system consisting of the best heating curve, the thermal state model, the billet temperature drop model and the optimal setting calculation is briefly introduced. Under the control of this system, the temperature and temperature uniformity of the billet can be precisely controlled when the variety of the specifications of the billet or the rolling line appear planted or unplanned production stops, so as to achieve the purpose of increasing output and saving energy.
