化铁炼钢的钢产量700万吨,约占全国钢产量的五分之一,年耗焦炭130万吨。现就化铁炼钢的节能潜力简述如下。 1.主要成绩和经验 1978年以来,合肥、长治、鸟鲁木齐等钢铁厂取消了二次化铁。唐钢一炼钢实现了热装三座高炉的铁水。全国化铁炉吨纲焦耗由1978年的250kg下降到今年一季度的165kg,涌现出了象上钢一厂三转炉车间(140kg/t)、上钢三厂二转炉车间(155 Iron steel production of 700 million tons of steel, steel accounts for about one-fifth of the country’s annual consumption of 1.3 million tons of coke. The energy saving potential of iron steelmaking is summarized as follows. 1. Main achievements and experience Since 1978, Hefei, Changzhi, Lujiazui and other steel mills canceled the ferric iron. Tangshan Iron and Steel achieved a hot blast three hot metal hot metal. The nationalized consumption of iron stoves tons of coke from 250kg in 1978 dropped to 165kg in the first quarter of this year, emerged as the first steel plant on the third converter (140kg / t), the second plant on the steel plant (155
