The good effect has been gained on the hypereutectic Al Si alloys treated with some double refining and modifying agents such as P, S, RE, Sr, Na, C, etc.
采用磷、硫、稀土、锶、钠、碳等进行双重细化变质处理过共晶铝硅合金已取得了良好的效果。
Control on harmful elements such as K, Na, f, s in smelting is short of effective measures, which results in BF capacity factor low, BF process not smoothly and serious environment pollution.
对冶炼中有害元素钾、钠、氟、硫的控制还缺乏有效手段,致使出现高炉利用系数偏低、高炉不畅和造成环境的严重污染。
The modifying elements used in hypoeutectic Al Si alloys, besides Na, there are also Sr, Te, Ba, Sb, K, RE, B, S, etc.
亚共晶铝硅合金的变质元素除钠以外,还有锶、碲、钡、锑、钾、稀土、硼、硫等。其中,应用较多的是含钠和锶的变质剂。
