鞍钢炼铁厂从1950年起,先后在三座中型高炉(容积600～800M~3)冶炼铸造生铁,1951～1952年全部改制炼钢生铁,1953～1956年又恢复了铸造生铁的冶炼,前后五年当中,特别是初期,由于没有找着冶炼铸造生铁的合适的操作制度,往往经过一个时期冶炼之后,高炉工作就会严重失常如:悬料、崩料、炉缶堆积、风口渣口大量烧坏,并且不间断地结瘤.1955年,失常情况扭转,可以在一座高炉上长期冶炼铸造铁,炉子工作没发生困难,各种经济技术指标有很大的改进.过去五年冶炼期中有66个炉月冶炼铸造铁,由于部份炉月检修、炸瘤、停炉、开炉、使用小送风机,
Ansteel Iron and Steel Works from 1950 onwards, has three medium-sized blast furnace (volume 600 ~ 800M ~ 3) smelting cast iron, 1951 ~ 1952 all the restructuring of pig iron, cast iron foundry from 1953 to 1956, before and after During the five years, especially in the early days, because of not finding a suitable operating system for smelting and casting pig iron, after a period of smelting, the work of the blast furnace would be seriously disrupted such as: suspended material, collapse material, furnace slag accumulation, Burned, and continue to nodulate .1955, the anomaly reversed, you can long-term smelting cast iron on a blast furnace, the furnace did not work hard, a variety of economic and technical indicators have greatly improved over the past five years in the refining period 66 furnace smelting cast iron, as part of the furnace overhaul, blasting, shutdown, open furnace, the use of small blower,
