Ukuhlelwa kwe-ferrosilicon

Ulwahlulo lwe-ferrosilicon:

I-Ferrosilicon 75, ngokubanzi, i-ferrosilicon enomxholo we-silicon ye-75%, i-carbon ephantsi, i-phosphorus kunye nomxholo wesulfure,

I-Ferrosilicon 72, ngokuqhelekileyo iqulethe i-72% ye-silicon, kunye nomxholo wekhabhoni, isulfure kunye ne-phosphorus phakathi.

I-Ferrosilicon 65, i-ferrosilicon enomxholo we-silicon ye-65%, umxholo ophezulu wekhabhoni, isulfure kunye ne-phosphorus.

Indima ye-ferrosilicon ekwenzeni intsimbi:

Okokuqala: Isetyenziselwa i-deoxidizer kunye ne-agent alloying 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 buphezulu kakhulu, ngoko ke i-ferrosilicon yi-deoxidizer eyomeleleyo yokwenza intsimbi.Imvula kunye ne-diffusion deoxygenation.

Okwesibini: Isetyenziswe njenge-inoculant kunye ne-nodulizer kwishishini lentsimbi.Intsimbi yentsimbi yinto ebalulekileyo yentsimbi kwishishini lanamhlanje.Ixabiso eliphantsi kunentsimbi, kulula ukunyibilika kunye nokunyibilika, inokusebenza okugqwesileyo kokusa kunye nesakhono esingcono sokufunxa ukothuka kunentsimbi.Ukongeza inani elithile le-ferrosilicon ukuphosa isinyithi kunokuthintela isinyithi kwiFom carbides, ukukhuthaza imvula kunye ne-spheroidization ye-graphite, ngoko ke ekuveliseni isinyithi se-ductile, i-ferrosilicon ibalulekile inoculant kunye ne-spheroidizer.

Okwesithathu: Isetyenziswa njenge-arhente yokunciphisa kwimveliso ye-ferroalloys.Ayisiyiyo kuphela indibaniselwano yeekhemikhali phakathi kwesilicon kunye neoksijini inkulu, kodwa nomxholo wekhabhoni we-silicon ferrosilicon ephezulu uphantsi kakhulu.Ke ngoko, i-silicon ferrosilicon ephezulu yiarhente yokunciphisa esetyenziswa ngokuqhelekileyo kwimveliso ye-carbon ferroalloys ephantsi kwishishini le-ferroalloy.

Okwesine: Ukusetyenziswa okuphambili kwezigaqa zendalo ze-ferrosilicon njenge-agent edibeneyo kwimveliso yentsimbi.Unako ukuphucula ubulukhuni, amandla, kunye nokumelana umhlwa yentsimbi, kwaye kwakhona ukuphucula weldability kunye machinability yentsimbi.

Okwesihlanu: Ukusetyenziswa kwezinye iindawo.Umgubo ocoliweyo okanye i-atomized ferrosilicon powder ingasetyenziswa njengesigaba sokunqunyanyiswa kwishishini lokulungisa izimbiwa.
