基于LCA评价方法结合高炉喷吹废塑料技术开展节能减排研究，进行高炉喷吹废塑料情景下钢铁主?纺芎暮虲O2气体减排分析。高炉喷吹废塑料后铁水、热轧卷和冷轧卷的能耗在钢厂边界内部有小幅度增加，随着喷吹比例的提高，增加幅度上升；而生命周期能耗有所减少，减少幅度随着喷吹比例的提高而增加；铁水、热轧卷和冷轧卷在钢厂边界内的CO2排放以及生命周期CO2排放都有不同程度的减少，随着喷吹比例的提高，CO2减排幅度迅速增加。
Combined with the injecting waste plastic into BF technology, LCA methodology was used to do analysis of the energy consumption and CO2 reduction of main products in steelworks. After injecting waste plastic into BF, the energy consumption of hot metal, hot rolling coil and cold rolling coil will have small increase in the boundary of steelworks. With a higher proportion of injection,the rate of increase is increased. The energy consumption of steel product will decrease in the boundary of whole life cycle. The rate of decrease is reduced with increasing injection ratio. The CO2 emission of hot metal, hot rolling coil and cold rolling coil will decrease both in the boundary of steelworks and the whole life cycle. Along with higher injection ratio, CO2 emissions reduction rate will be rapidly increased.
