通过对首秦公司天然气消耗情况对标分析,得出减少钢包、中间包以及鱼雷罐等设备烘烤使用天然气,是降低天然气消耗的重要手段.通过理论计算及工艺试验,证明低热值转炉煤气可以替代天然气进行工艺烘烤,保证用能设备内衬温度均衡、稳定.同时通过回收试验获得最佳的转炉煤气回收区间,提高转炉煤气回收水平,确保钢包、中间包、鱼雷罐等设备的转炉煤气烘烤用量需求,达到停用天然气烘烤的目的.燃气资源的梯级利用,有效降低了首秦公司天然气消耗水平,提高了转炉煤气回收利用率,降低了能源成本,减少了环境污染,对国内同类型钢铁企业燃气资源梯级利用具有一定的借鉴意义.“,”Based on the benchmarking about the natural gas consumption in Shouqin Company,it was found that re ducing the natural gas baking of the ladle,tundish and torpedo bottle during baking was an important means to re duce the natural gas consumption.Through the theoretical calculation and process experiment,it was proved that the low heat value LDG can replace the natural gas during baking process and can keep the temperature of the energy consumption equipment lining balanced and stable.And the best LDG recovery interval range of converter blowing process was obtained by the recovery experiments,which can increase the level of LDG recovery,meet the demand of the converter gas for baking the ladle,tundish and torpedo ladle,and achieve the goal of stopping using the natu ral gas.Through the cascade utilization of the fuel gas resource,the level of natural gas consumption was effectively reduced,the LDG utilization ratio was increased,the energy cost was decreased,and the environmental pollution was reduced,which can provide a certain reference for the cascade utilization of the fuel gas resource in the steel en terprises of the same type in China.
