新抚钢厂这几年来焦比和成本连年下降,经济效益逐年上升。究其原因是在高炉开展了如下的节能工作: (1) 炼铁工序能耗的高低与其上下工序有着密切关系,因此该厂通过科学调度、整体协作和科研攻关等管理措施,为炼钢工序节能降耗创造有利条件。 (2) 投资175万元,为高炉安装了喷吹煤粉的装置。这几年来,喷煤量逐年稳定上升,不仅解决了焦炭不足的问题,而且提高了高炉产量,改善了生铁的质量。
The new steel plant in recent years, coke ratio and cost decline year after year, economic efficiency increased year by year. The reason is that the following energy-saving work is carried out in the blast furnace: (1) The energy consumption of the ironmaking process is closely related to the process of its up-and-down process. Therefore, through scientific management, overall coordination and scientific research, Save energy and create favorable conditions. (2) Invest 1.75 million yuan to install a pulverized coal injection device for the blast furnace. In recent years, the amount of coal injected steadily increased year by year, not only solved the problem of insufficient coke, but also increased the production of blast furnace and improved the quality of pig iron.
