(1) Isetyenziswe njenge-deoxidizer kunye ne-alloying agent kwishishini le-steelmaking. Ukuze ufumane isinyithi kunye nokubunjwa kweekhemikhali ezifanelekileyo kunye nokuqinisekisa umgangatho wensimbi, i-deoxidation kufuneka iqhutywe kwinqanaba lokugqibela le-steelmaking. Ubudlelwane bekhemikhali phakathi kwesilicon kunye neoksijini inkulu kakhulu, ke i-ferrosilicon sisisidididi esiyimfuneko kwishishini lokwenza intsimbi. Kwimveliso yokwenza intsimbi, ngaphandle kwezinye iintsimbi ezibilayo, phantse zonke iintlobo zentsimbi zisebenzisa i-ferrosilicon njenge-deoxidizer eyomeleleyo yokukhupha imvula kunye ne-diffusion deoxidation. Ukongeza inani elithile le-silicon kwintsimbi kunokuphucula kakhulu amandla, ukuqina kunye nokuqina kwentsimbi. Ngoko ke, isetyenziswa ngokubanzi ekunyibilikiseni insimbi yesakhiwo (equlethe i-siO. 40% ~ 1.75%) kunye nensimbi yesixhobo (equlethe i-siO. 30%). ~ 1.8%), intsimbi yasentwasahlobo (equlethe i-Si O. 40% ~ 2.8%) kunye nezinye iindidi zetsimbi, umlinganiselo othile we-ferrosilicon kufuneka wongezwe njenge-agent alloying. I-Silicon nayo ineempawu zokuchasana okukhulu, ukungahambi kakuhle kwe-thermal kunye ne-conductivity enamandla yamagnetic. Insimbi iqulethe inani elithile le-silicon, elinokuphucula amandla ombane wentsimbi, ukunciphisa ilahleko ye-hysteresis, kunye nokunciphisa ilahleko yangoku ye-eddy. Ngoko ke, i-ferrosilicon iphinda isetyenziswe njenge-alloying agent xa inyibilikisa i-silicon yensimbi, njengentsimbi ephantsi ye-silicon yeemotor (equlethe i-Si O. 80% ukuya kwi-2.80%) kunye ne-silicon steel for transformers (equlethe i-Si 2.81% ukuya kwi-4.8%). sebenzisa.
Ukongezelela, kwi-industry ye-steelmaking, i-ferrosilicon powder inokukhulula inani elikhulu lobushushu xa litshiswa kumaqondo aphezulu kwaye lihlala lisetyenziswa njenge-ejenti yokufudumeza i-ingot caps yensimbi ukuphucula umgangatho kunye nezinga lokubuyisela i-ingots zetsimbi.
(2) Isetyenziswe njenge-inoculant kunye ne-spheroidizing agent kwishishini lentsimbi. Intsimbi yentsimbi yinto ebalulekileyo yentsimbi kwishishini lanamhlanje. Ixabiso eliphantsi kunentsimbi, kulula ukunyibilika kunye nokunyibilika, ineempawu zokuphosa ezigqwesileyo kunye nokuxhathisa okungcono kakhulu kweenyikima kunentsimbi. Ngokukodwa isinyithi se-ductile, iimpawu zayo zomatshini zifikelela okanye zisondele kwezo zentsimbi. ukusebenza. Ukongeza inani elithile le-ferrosilicon ukuphosa isinyithi kunokuthintela ukubunjwa kwe-carbides kwintsimbi kunye nokukhuthaza imvula kunye ne-spheroidization ye-graphite. Ngoko ke, ekuveliseni isinyithi se-ductile, i-ferrosilicon yinto ebalulekileyo ye-inoculant (inceda ukukhupha i-graphite) kunye ne-agent agent. .
(3) Isetyenziswe njenge-arhente yokunciphisa kwimveliso ye-ferroalloy. Ayisiyiyo kuphela indibaniselwano yeekhemikhali phakathi kwesilicon kunye neoksijini iphezulu kakhulu, kodwa umxholo wekhabhoni we-silicon ferrosilicon uphantsi kakhulu. Ke ngoko, i-silicon ferrosilicon ephezulu (okanye i-silicon alloy) sisixhobo sokunciphisa esisetyenziswa ngokuqhelekileyo kwishishini le-ferroalloy xa kusenziwa i-ferroalloys ephantsi kwekhabhoni.
