这次冶金部在我厂召开全国钢铁中小骨干企业铁前系统生产剖析会,必将促使我们把铁前系统生产水平提高到一个新的高度。现在将我厂近几年在铁前系统所做的工作作一简要汇报。我们厂于1958年开始建设。目前,炼铁系统有300m~3高炉3座、39m~2烧结机2台、42孔焦炉1组以及从日本引进的氯化球团设备1套。二十多年来,我厂生产几经起落,一直徘徊在低水平上,发展速度十分缓慢。1984年以后,由于集中力量从铁前系统抓起,重点在设备、原料、管理及操作上做了一些工作,生产水平才有了一定的提高,各项技术经济指标才有了一些起色。我厂的炼铁生产,大体经过了三个阶段:(1)1984年以前为徘徊阶段,高炉利用系数一直在1.33以下;焦比除1984年外,几乎都在700kg以上;(2)1985年为起步阶段,在于杭钢召开的地方骨干企业经济效 The Metallurgical Department in our plant held in the small and medium-sized iron and steel enterprises in the iron production system analysis before the meeting, will surely urge us to raise the production level before the iron system to a new height. Now I plant in recent years in the iron system before the work done for a brief report. Our factory started construction in 1958. At present, the ironmaking system has 3 300m ~ 3 blast furnaces, 2 sets of 39m ~ 2 sintering machines, 1 set of 42-hole coke oven and 1 set of chlorinated pellet equipment imported from Japan. Over the past 20 years, I plant a few ups and downs of production, has been hovering at a low level, the pace of development is very slow. Since 1984, due to the concentration of power from the pre-iron system, focusing on equipment, raw materials, management and operation of some work, the production level has been a certain increase, the various technical and economic indicators have some improvement. The ironmaking production of our factory has basically gone through three stages: (1) the hibernation stage before 1984, the blast furnace utilization coefficient has been under 1.33; the coke ratio is almost above 700kg except in 1984; (2) For the initial stage, is the economic efficiency of local key enterprises held by Hanggang
