1炼铁在钢铁生产上的意义炼铁是钢铁生产中的一个重要环节。高炉冶炼出来的生铁，最主要的是炼钢生铁，其次是铸造生铁，另外还有少量的合金生铁。炼钢生铁质量的好坏，直接影响着钢的质量，炼出生铁的多少，则影响着钢的产量。所以炼铁工作者不但要保证高炉的正常生产，而且要 Iron and steel production in the significance of Iron and steel production is an important part. Blast furnace smelting pig iron, the most important is steelmaking pig iron, followed by cast iron, in addition to a small amount of alloy pig iron. The quality of steelmaking pig iron quality, a direct impact on the quality of steel, refining the number of pig iron, it affects the steel production. Therefore, ironmaking workers not only to ensure the normal production of blast furnace, but also
