Takaitaccen bincike na dalilan da ke haifar da ƙarancin abun ciki na ferrosilicon ya narke

Ferrosilicon wani ƙarfe ne wanda ya ƙunshi baƙin ƙarfe da silicon. A zamanin yau, ferrosilicon yana da aikace-aikacen da yawa. Ferrosilicon kuma za a iya amfani da a matsayin alloying kashi ƙari kuma shi ne yadu amfani a low-alloy tsarin karfe, spring karfe, hali karfe, zafi-resistant karfe da lantarki silicon karfe. Daga cikin su, ana amfani da ferrosilicon sau da yawa azaman wakili mai ragewa a cikin samar da ferroalloy da masana'antar sinadarai. Duk da haka, mutane da yawa sun fahimci amfani da ferrosilicon kawai kuma ba su fahimci narkewar ferrosilicon da matsalolin da za a iya samu a lokacin narkewa ba. Domin zurfafa fahimtar kowa game da ferrosilicon, masu samar da ferrosilicon za su yi nazari a taƙaice dalilan ƙarancin abun ciki na carbon a cikin ferrosilicon.

Babban dalilin da ya sa ferrosilicon da aka narke yana da ƙananan abubuwan da ke cikin carbon shi ne, lokacin da masana'antun suka narke ferrosilicon, suna amfani da coke a matsayin wakili mai ragewa, ta yadda na'urorin lantarki da suke gasa da kansu waɗanda suka fi sauƙi ga carburize suna amfani da bulo na coke don gina tapholes da Flow iron trough. , wani lokacin amfani da graphite foda don gashi ingot mold, amfani da carbon samfurin cokali don daukar ruwa samfurori, da dai sauransu A takaice, a lokacin smelting. ferrosilicon daga amsawa a cikin tanderun har sai an taɓa ƙarfe, a fili akwai dama da yawa don saduwa da carbon yayin aikin zubar da ruwa. Mafi girman abin da ke cikin siliki a cikin ferrosilicon, ƙananan abubuwan da ke cikin carbon. Lokacin da abun cikin siliki a cikin ferrosilicon ya fi kusan 30%, yawancin carbon a cikin ferrosilicon yana wanzuwa a cikin yanayin silicon carbide (SiC). Silicon carbide yana da sauƙi oxidized da kuma rage ta silicon dioxide ko silicon monoxide a cikin crucible. Silicon carbide yana da ƙarancin solubility a cikin ferrosilicon, musamman lokacin da zafin jiki ya yi ƙasa, kuma yana da sauƙin hazo da iyo. Saboda haka, siliki carbide da ya rage a cikin ferrosilicon yana da ƙasa sosai, don haka abun cikin carbon na ferrosilicon yana da ƙasa sosai.
