分析了济钢350m3高炉高富氧对产量、理论燃烧温度、炉况顺行状况、焦比和生产效益的影响。高富氧可提高产量,但升高焦比和高炉理论燃烧温度,一定程度上影响高炉顺行,存在富氧效益最大化的适宜富氧率。高炉生产应低富氧高喷煤,根据济钢目前的情况,富氧率以2%～3%为宜。
The effects of high oxygen enrichment on yield, theoretical combustion temperature, furnace operating conditions, coke ratio and production efficiency of Jinan Iron and Steel 350m3 blast furnace were analyzed. High oxygen enrichment can increase the yield, but increasing the coke ratio and the blast furnace theoretical combustion temperature, to a certain extent, affect the blast furnace in the right direction, there is the optimum oxygen enrichment efficiency of oxygen enrichment rate. Blast furnace production should be low-oxygen high-jet coal, according to the current situation in Jinan Iron and Steel, oxygen rate of 2% to 3% is appropriate.
