武钢炼铁厂1989年1～6月四座高炉实产生铁207.68万吨,与1988年同期比较(下同),少产铁19.92万吨,降低率为8.75％;入炉焦比498.6公斤/吨,升高2.9公斤/吨,上升率为0.59％;综合焦比为541.6公斤)吨铁,升高10.1公斤/吨,上升率为1.9％;燃料比559.4公斤/吨铁,上升5.8公斤/吨,上升率为1.05％;工序能耗484.9公斤标煤/吨铁,升高3.5公斤标煤/吨,上升率为0.73％。同公司1989年节能降耗方针目标值入炉焦比470公斤/吨铁、工序能耗465公斤标煤/吨铁要求有较大差距。现将能耗升高因素与降低措施剖析如下。
Iron and steel plant in WISCO from January to June 1989 produced a total of 2,076,800 tons of iron, compared with the same period of 1988 (the same below), with a small iron production of 1,992,000 tons, a reduction rate of 8.75%; a coke ratio of 498.6 kg / ton , An increase of 2.9 kg / tonne, an increase of 0.59%; consolidated coke ratio of 541.6 kg) ton of iron, an increase of 10.1 kg / tonne, an increase of 1.9%; fuel ratio of 559.4 kg / tonne of iron, up 5.8 kg / tonne , The rate of increase of 1.05%; process energy consumption of 484.9 kilograms of standard coal / ton of iron, raising 3.5 kg standard coal / ton, the rate of increase of 0.73%. With the company’s energy-saving target in 1989, the target value into the furnace coke ratio of 470 kg / ton of iron, the process energy consumption of 465 kg of standard coal / tonne iron requires a larger gap. Now the factors that increase energy consumption and reduce the following analysis.
