摘　　要：结合京唐热轧2 250 mm加热炉烟气余热回收控制系统的调试过程,分析了增设烟气余热回收蒸发器后对原有汽化冷却控制系统及炉膛压力控制系统的影响,并最终通过调整仪表设备参数、升级老化仪表设备、优化控制策略,克服了在烟气量剧烈变化时对加热炉炉膛压力控制、汽包液位控制造成的波动,实现了全自动控制。Combined with the debugging process of flue gas waste heat recovery control system of 2 250 mm reheating furnace in Jingtang Hot Rolling Mill, the influence of adding flue gas waste heat recovery evaporator on original vaporization cooling control system and furnace pressure control system is analyzed. By adjusting the instrument parameters, upgrading the aging instrument and optimizing the control strategy, the fluctuation caused by the pressure control in the furnace and the level control in the drum when the smoke volume changes dramatically is overcomed, and realizes the fully automatic control is realized.
