摘 要：<正> Based on the detailed analysis of the third coke oven in BaoSteel, a feedback control strategy of longitudinal temperature and finished carbonization time of coke ovens was proposed and it was applied to the thkd coke oven in BaoSteel. As a result, the ratio of the instance that the absolute deviation of the longitudinal temperature is within ±7℃ and the finished carbonization time within±10 min is more than 80%, having acquired the patent saving effect of an energy consumption lowered by 2.92%. At the same time, it can provide an example for the same coke ovens inside and outside the nation.
