硅鐵的用途有哪些看金屬硅廠家來解答!

發布:安陽坤鑫達冶金耐材有限公司瀏覽:713次


  硅鐵是以焦炭、鋼屑、石英為原料,用電爐冶煉制成的。但是大部分的人對硅鐵只是簡單地了解,知道它主要用于重工業中。那么它的主要用途是什么呢?金屬硅廠家的技術人員今天就給大家來解釋一下。


金屬硅廠家

  硅鐵是煉鋼工業中必不可少的脫氧劑。炬鋼中,硅鐵用于沉淀脫氧和擴散脫氧。在鋼中添加一定數量的硅,能顯著的提高鋼的強度、硬度和彈性,因而在冶煉結構鋼時,也把硅鐵作為合金劑使用。特別是球墨鑄鐵,其機械性能達到或接近鋼的機械性能。在鑄鐵中加入一定量的硅鐵能阻止鐵中形成碳化物、有利于石墨的析出和球化,因而在球墨鑄鐵生產中,硅鐵是一種重要的孕育劑和球化劑。高硅硅鐵或硅質合金在鐵合金工業中用作生產低碳鐵合金的還原劑。硅鐵加入鑄鐵中可作球墨鑄鐵的孕育劑,且能阻止碳化物形成,有利于石墨的析出和球化,改化鑄鐵性能。硅鐵在皮江法煉鎂中常用于金屬鎂的高溫冶煉過程中,將其鎂置換出來,對金屬鎂生產起著很大的作用。在其他方面的用途。磨細或霧化處理過的硅鐵粉,在選礦工業中可作為懸浮相。在焊條制造業中可作為焊條的涂料。高硅硅鐵在化學工業中可用于制造硅酮等產品。
