Silicon da oxygen cikin sauƙin haɗuwa don samar da siliki. Sabili da haka, ana amfani da ferrosilicon sau da yawa azaman deoxidizer a aikin ƙarfe. A lokaci guda kuma, saboda SiO2 yana fitar da babban adadin zafi lokacin da aka samar da shi, yana da amfani don ƙara yawan zafin jiki na narkakkar karfe yayin da ake deoxidizing.
Ana amfani da Ferrosilicon azaman abin haɗakarwa. An yadu amfani da low gami tsarin karfe, bonded karfe, spring karfe, hali karfe, zafi-resistant karfe da lantarki silicon karfe. Ferrosilicon galibi ana amfani dashi azaman wakili mai ragewa a masana'antar ferroalloy da masana'antar sinadarai. Abubuwan da ke cikin silicon sun kai 95% -99%. Ana amfani da siliki mai tsafta don yin silikon kristal guda ɗaya ko shirya kayan haɗin ƙarfe mara ƙarfe.
Amfani: Ferrosilicon ana amfani dashi sosai a cikin masana'antar ƙarfe, masana'anta da sauran masana'antu.
Ferrosilicon shine mahimmin deoxidizer a cikin masana'antar yin ƙarfe. A cikin ƙera ƙarfe, ana amfani da ferrosilicon don hazo deoxidation da difffusion deoxidation.
