【摘要】 介绍了宝钢三期焦炉直行温度和火落时间双反馈控制系统的在线应用状况,结果表明,系统投运后焦炉直行温度的控制精度在±7℃以内,火落时间判定在±10min内的命中率达到80%以上,炼焦耗热量降低了2.92%。更多还原

【Abstract】 The on line application of the dual feedback system for the coke oven longitudinal temperature and coking end time in phase III of the Bao Steel is described. Results show that after the commissioning of the system the control accuracy of the coke oven longitudinal temperature is within ±7℃, the coking end time determination accuracy is up to 80%within ±10min and 2.92%of cokemaking heat consumption lowered.更多还原
