Kusanthula mwachidule zifukwa zochepetsera mpweya wa ferrosilicon wosungunuka

Ferrosilicon ndi aloyi wachitsulo wopangidwa ndi chitsulo ndi silicon. Masiku ano, ferrosilicon ili ndi ntchito zambiri. Ferrosilicon itha kugwiritsidwanso ntchito ngati chowonjezera cha alloying ndipo chimagwiritsidwa ntchito kwambiri muzitsulo zotsika, zitsulo zamasika, zitsulo zokhala ndi chitsulo, chitsulo chosagwira kutentha ndi chitsulo chamagetsi cha silicon. Mwa iwo, ferrosilicon nthawi zambiri amagwiritsidwa ntchito ngati chochepetsera pakupanga ferroalloy ndi makampani opanga mankhwala. Komabe, anthu ambiri amangomvetsetsa ntchito za ferrosilicon ndipo samamvetsetsa kusungunula kwa ferrosilicon ndi mavuto omwe angapezeke pakusungunula. Pofuna kukulitsa kumvetsetsa kwa aliyense za ferrosilicon, ogulitsa ferrosilicon adzasanthula mwachidule zifukwa zomwe zili ndi mpweya wochepa mu ferrosilicon.

Chifukwa chachikulu chomwe ferrosilicon yosungunuka imakhala ndi mpweya wochepa wa carbon ndikuti pamene opanga amasungunula ferrosilicon, amagwiritsa ntchito coke monga chochepetsera, kotero kuti ma electrode ophika okha omwe ndi osavuta kuyika carburize amagwiritsa ntchito njerwa za coke kuti apange ma tapholes ndi Flow iron through. , nthawi zina gwiritsani ntchito ufa wa graphite kuti muveke nkhungu ya ingot, gwiritsani ntchito supuni ya carbon chitsanzo kuti mutenge zitsanzo zamadzimadzi, etc. Mwachidule, panthawi ya smelting wa ferrosilicon kuchokera momwe mu ng'anjo mpaka chitsulo chikugwedezeka, mwachiwonekere pali mipata yambiri yokhudzana ndi carbon panthawi yothira. Kukwera kwa silicon mu ferrosilicon kumachepetsa mpweya wake. Pamene silicon zili mu ferrosilicon ndi wamkulu kuposa 30%, ambiri a carbon mu ferrosilicon alipo mu boma la pakachitsulo carbide (SiC). Silicon carbide imasungunuka mosavuta ndikuchepetsedwa ndi silicon dioxide kapena silicon monoxide mu crucible. Silicon carbide imakhala ndi kusungunuka kochepa kwambiri mu ferrosilicon, makamaka kutentha kukakhala kochepa, ndipo ndikosavuta kugwa ndikuyandama. Chifukwa chake, silicon carbide yotsalira mu ferrosilicon ndiyotsika kwambiri, kotero kuti mpweya wa ferrosilicon ndiwotsika kwambiri.
