1985年我厂炼铁生产各项经济技术指标取得建厂近30年来的最好水平(见下表)。而指标历史最好水平 1985年利用系数T/m~3 1.83 1.96入炉焦比kg 565 559综合焦比kg 624 612工序能耗kg 575 556CO_2％ 13.84 14.49风温℃ 1027 1014冶炼强度T/m~3 0.995 1.012这一年中的原、燃料条件以及设备状况,都是相当困难的。入炉矿石品位低,渣铁比升高,三座高炉设备比较陈旧,且受碱、铅的危害,炉体破损,炉底侵蚀,炉基温度逐步上升,严重威胁生产的正常进行。然而,依靠技术进步,我厂1985年三座84m~3高炉,
In 1985, the economic and technical indexes of our ironmaking production achieved the best level in the past 30 years (see the table below). While the index of the best level of history in 1985 utilization factor T / m ~ 3 1.83 1.96 into the coke ratio kg 565 559 integrated coke kg 624 612 energy consumption kg 575 556CO_2% 13.84 14.49 air temperature ℃ 1027 1014 smelting strength T / m ~ 3 0.995 1.012 The conditions of the original fuel and the condition of the equipment during the year were quite difficult. The quality of ore into the furnace is low, slag-iron ratio is increased, the three blast furnace equipment is relatively old, and by the alkali, lead hazards, furnace damage, bottom erosion, furnace base temperature gradually increased, a serious threat to the normal production. However, relying on technological progress, our factory in 1985 three 84m ~ 3 blast furnace,
