从1974年到1978年底,我厂四座高炉先后完成了大修和改造。每座高炉容积都扩大到17米~3,各种设备也比较完善。但是,由于原料的基础工作没做好,焦炭消耗占全厂总能耗80%以上,很难降低下来。近年来,我厂狠抓了原料基础工作,严格控制入炉原料质量,促使入炉焦比逐年下降,工序能耗逐年递减,取得了1983年平均折合焦比609公斤,工序能耗607公斤的好成绩,如表1所示。
From 1974 to the end of 1978, the four blast furnaces of our factory have successively completed overhaul and renovation. Each blast furnace volume has been expanded to 17 meters ~ 3, a variety of equipment is also more perfect. However, because the basic work of raw materials is not done well, the coke consumption accounts for more than 80% of the total energy consumption of the whole plant, so it is hard to be reduced. In recent years, I pay close attention to raw materials factory work, strictly control the quality of raw materials into the furnace, and promote the furnace coke ratio decreased year by year, process energy consumption decreased year by year, made in 1983 the average fold coke ratio 609 kg, process energy consumption 607 kg Good results, as shown in Table 1.
