喷洒焦炭添加剂高炉工业性试验

Coke Sprayed with Coke Additive

针对昆明钢铁股份有限责任公司的现场情况,选择合适的喷洒点向焦炭喷洒焦炭添加剂溶液后,在6号高炉(2 000 m3)进行工业性试验。试验结果表明:焦炭添加剂在试验期间,喷洒过焦炭添加剂溶液的焦炭反应性(CRI)较未喷洒焦炭添加剂溶液的CRI降低了3.13个百分点,CSR提高了4.72个百分点;与基准期相比,试验期间6号高炉的产量日平均提高66.69 t,入炉焦比日平均降低5.21 kg/t(铁),炉温波动幅度小,w([S])合格,生铁合格率达到100%。

The coke was sprayed with coke additive at suitable site and used for experiment. The results are as follows： the coke additive additive has no pollution to environment, is harmless to human beings. The coke reaction index （CRI） of the coke sprayed with coke additive is decreased by 3. 13 percentage, and the coke strength after reaction （CSR） is increased by 4.72 percentage in eomparsion with non sprayed coke. During the industrial experiment, the average hot metal output was increased by 66.69 ton per day, the coke rate is reduced by 5.21 kg per ton hot metal, the fluctuations of furnace temperture is small, sulphur content of hot metal is qualitified and qualification rate of hot metal is 100%.
