本专利所叙述的是钢铁工业中所应用的非粉化性脱氧用硅铝铁合金。以往作为脱氧剂通常是用 FeSi、FeMn、CaSi 等合金,而 FeAlSi 合金虽然具有良好的复合脱氧的效果,但几乎还没有进入实用的阶段,其原因是大多数的 FeAlSi 合金极易产生粉化现象。特别是作为脱氧剂之用的 FeAlSi 合金,在贮藏过程中一旦粉化,使用起来比较困难,而且导至脱氧作用及效率都降低了,因此如何使这种合金成为非粉 Described in this patent is the non-powdered deoxidation silicon-aluminum-iron alloy used in the steel industry. In the past as the deoxidizer is usually used FeSi, FeMn, CaSi and other alloys, while the FeAlSi alloy has good composite deoxidation effect, but almost no practical stage, the reason is that most of the FeAlSi alloy prone to chalking . Particularly, the FeAlSi alloy used as a deoxidizing agent is difficult to use once it is pulverized during storage and leads to deoxidation and efficiency reduction. Therefore, how to make this alloy non-powder
