高炉焦比目标优化模型应用及结果分析

Optimization Aimed at the Lowest Coke Consumption by Model and Analysis of the Application

介绍了目标高炉应用焦比优化模型在线运行的环境．通过模型在线运行，得到了有 关参数的优化结果．将优化结果与实际生产参数比较，结果是目标高炉降低烧结矿在熟料中的 比例，提高球团矿比例，同时提高风温和富氧率．在煤粉喷吹量达１８６ ｋｇ／ｔ的基础上，可望将焦 比降低到３００ｋｇ／ｔ左右水平．

Optimization by model aimed at the lowest coke consumption at the given condition of the blast furnace. The environment of the optimization model used was introduced. Some parameters were obtained by modeling on line. Comparing the results parameters of optimization with that of real production, it was shows that the rate of the sinter quantity used ought to be reduced and the pellet quantity increase. The temperature of the blast and the oxygen enrichment should use at the highest level that the blast furnace could supply. Based on the condition the pulverized coal injection at 186 kg/t, the coke consumption may be lowers to the level of 300 kg/t or so.
