FERROALLOY

Ferroalloy wani abu ne da ya ƙunshi ƙarfe ɗaya ko fiye da ƙarfe ko ƙarfe wanda aka haɗa da ƙarfe.Misali, ferrosilicon silicide ne da silicon da baƙin ƙarfe suka yi, irin su Fe2Si, Fe5Si3, FeSi, FeSi2, da sauransu. Su ne manyan abubuwan da ke cikin ferrosilicon.Silicon a cikin ferrosilicon galibi yana wanzuwa a cikin sigar FeSi da FeSi2, musamman FeSi yana da kwanciyar hankali.Narke batu na daban-daban sassa na ferrosilicon shi ma daban-daban, misali, 45% ferrosilicon yana da wani narkewa batu na 1260 ℃ da 75% ferrosilicon yana da wani narkewa batu na 1340 ℃.Iron manganese wani abu ne na manganese da baƙin ƙarfe, wanda kuma ya ƙunshi ƙananan abubuwa kamar carbon, silicon, da phosphorus.Dangane da abubuwan da ke cikin carbon, an raba baƙin ƙarfe na manganese zuwa babban ƙarfe na manganese na carbon, matsakaicin ƙarfe na manganese, da ƙananan ƙarfe na manganese na carbon.Manganese baƙin ƙarfe gami da isassun abun ciki na silicon ana kiransa silicon manganese gami.
Ferroalloys ba kayan ƙarfe ba ne waɗanda za a iya amfani da su kai tsaye, amma galibi ana amfani da su azaman tsaka-tsakin albarkatun ƙasa don Scavenger Oxygen, rage wakili da ƙari na gami a cikin samarwa da masana'antar simintin ƙarfe.
Rarraba na ferroalloys
Tare da haɓaka kimiyya da fasaha na zamani, masana'antu daban-daban suna daɗaɗa buƙatu masu yawa don nau'ikan nau'ikan ƙarfe da aikin ƙarfe, don haka sanya buƙatu mafi girma akan ferroalloys.Akwai nau'ikan ferroalloys iri-iri da hanyoyin rarrabuwa daban-daban, waɗanda galibi ana rarraba su bisa ga hanyoyin masu zuwa:
(1) Bisa ga rarrabuwa na manyan abubuwa a cikin ferroalloys, za a iya raba su zuwa jerin ferroalloys kamar silicon, manganese, chromium, vanadium, titanium, tungsten, molybdenum, da dai sauransu.
(2) Dangane da abun ciki na carbon a cikin ferroalloys, ana iya rarraba su zuwa babban carbon, matsakaicin carbon, ƙananan carbon, micro carbon, ultrafine carbon, da sauran nau'ikan.
(3) Bisa ga samar da hanyoyin, shi za a iya raba zuwa kashi: fashewa tanderu ferroalloy, lantarki makera ferroalloy, daga tanderun (karfe thermal Hanyar) ferroalloy, injin m rage ferroalloy, Converter ferroalloy, electrolytic ferroalloy, da dai sauransu Bugu da kari, akwai akwai. musamman baƙin ƙarfe gami irin su oxide blocks da dumama baƙin ƙarfe gami.
(4) Bisa ga rarrabuwa na biyu ko fiye alloying abubuwa kunshe a cikin mahara baƙin ƙarfe gami, manyan iri sun hada da silicon aluminum gami, silicon calcium gami, silicon manganese aluminum gami, silicon calcium aluminum gami, silicon calcium barium alloy, silicon aluminum barium calcium. gami, da sauransu.
Daga cikin manyan nau'ikan ferroalloy guda uku na silicon, manganese, da chromium, silicon iron, silicon manganese, da chromium iron sune nau'ikan da suka fi girma.
