我厂每年消耗烧结、球团炉篦子和台车档板两千多吨,只炉篦子一项就达一千五百多吨。六年多来,我们将侧送风冲天炉改为中央送风三节炉。我们体会这种炉子构造简单,便于制做;操作易掌握;能量损失少,热效率高,焦铁比低,熔化率高,可满足合金铸铁的技术条件。目前总焦铁比为1∶13左右,层焦铁比1∶15,每周开三次炉,每次作业六小时化铁18吨。原用冲天炉焦铁比为1∶5,现按1∶13计算,每年节约优质冶金焦185吨。现介绍如下。
Our annual consumption of sintering, pellet furnace grate and bogie billet more than two thousand tons, only a furnace grate up to more than one thousand five hundred tons. For more than six years, we changed the side blast furnace to the central blast furnace. We understand that this stove is simple in structure and easy to manufacture. It is easy to operate and operate. It has less energy loss, high thermal efficiency, low coke-iron ratio and high melting rate to meet the technical requirements of alloy cast iron. At present, the total iron and iron ratio of about 1:13, the ratio of iron coke layer 1:15, open three times a week furnace, each operation six hours of iron 18 tons. The original cupola than the iron and iron ratio of 1: 5, now 1:13 calculation, annual savings of 185 tons of high-quality metallurgical coke. Now introduced as follows.
