炼钢生产中,在炉后向盛钢桶定量地加入铝块进行脱氧和调整含铝量的操作方法已实施多年。由于铝的比重小,高温下极易氧化,其加入方法受加入方式、生产工艺条件的影响较大,因而铝在钢中的收得率不够稳定,且铝的消耗量较大。因此,如何有效地将铝加入钢水中,是炼钢工作者十分关注且 Steelmaking operations, after the furnace to the ladle quantitatively adding aluminum blocks for deoxidation and adjustment of aluminum content has been implemented for many years. As the proportion of aluminum is small, extremely easy to oxidize under high temperature, the adding method is affected by adding method and production process conditions, so the yield of aluminum in steel is not stable enough and the consumption of aluminum is larger. Therefore, how to effectively add aluminum to molten steel is a concern of steel makers
