往钢包炉中加入合金已广泛地用于钢水的炉外精炼工艺过程。目前已开发的4种新钢液中加铝法,非但能减少铝的消耗量,且能使钢液纯净,具有命中率高、标准偏差小等优点,与传统的加入铝块脱氧法相比,其结果见下表。 Joining ladle furnace alloy has been widely used in the molten steel furnace refining process. At present, four kinds of new molten steel have been developed by adding aluminum method, which not only can reduce the consumption of aluminum, but also make the molten steel pure, with a hit rate, the standard deviation is small, compared with traditional aluminum deoxidation method, The results in the table below.
