Ziziphi izinto ezisetyenziswa kwi-ferrosilicon?

I-Ferrosilicon, i-alloy ye-silicon kunye nentsimbi, ifumaneka kwi-45%, i-65%, i-75% kunye ne-90% yamabanga e-silicon.Ukusetyenziswa kwayo kubanzi kakhulu, ngoko umenzi we-ferrosilicon u-Anhui Fitech Materials Co., Ltd uya kuhlalutya ukusetyenziswa kwayo okuthe ngqo kula manqaku mathathu alandelayo.

Okokuqala, isetyenziswa njenge-deoxidizer kunye ne-agent alloying kwishishini lokwenza intsimbi.Ukuze ufumane isinyithi kunye nokubunjwa kweekhemikhali ezifanelekileyo kunye nokuqinisekisa umgangatho wensimbi, i-deoxidation kufuneka iqhutywe ekupheleni kwe-steelmaking.Ubudlelwane bekhemikhali phakathi kwesilicon kunye neoksijini inkulu kakhulu.Ngoko ke, i-ferrosilicon yi-deoxidizer enamandla yokwenza i-steelmaking, esetyenziselwa imvula kunye ne-diffusion deoxidation.Ukongeza inani elithile le-silicon kwintsimbi kunokuphucula kakhulu amandla, ukuqina kunye nokuqina kwentsimbi.
Ngoko ke, i-ferrosilicon iphinda isetyenziswe njenge-alloying agent xa i-smelting structural iron (equlethe i-silicon 0.40-1.75%), insimbi yensimbi (equlethe i-silicon 0.30-1.8%), insimbi yasentwasahlobo (equlethe i-silicon 0.40-2.8%) kunye ne-silicon yensimbi ye-transformer ( equlethe i-silicon 2.81-4.8%).

Ukongeza, kwishishini lokwenza intsimbi, i-ferrosilicon powder inokukhulula inani elikhulu lobushushu phantsi kobushushu obuphezulu.Ihlala isetyenziswa njenge-ejenti yokufudumala ye-ingot cap ukuphucula umgangatho kunye nokubuyiswa kwe-ingot.

Okwesibini, isetyenziswa njenge-inoculant kunye ne-spheroidizing agent kwishishini lentsimbi.Intsimbi yentsimbi yinto ebalulekileyo yentsimbi kwishishini lanamhlanje.Ixabiso eliphantsi kunentsimbi kwaye kulula ukuyinyibilika nokunyibilika.Ineempawu zokuphosa ezigqwesileyo kunye nobuchule obungcono bomothuko kunentsimbi.Ngokukodwa i-nodular cast iron, iimpawu zayo zomatshini zifikelela okanye zisondele kwiimpawu ze-mechanical of steel.Ukongeza inani elithile le-ferrosilicon ukuphosa isinyithi kunokuthintela ukubunjwa kwe-carbide kwintsimbi kunye nokukhuthaza imvula kunye ne-spheroidization ye-graphite.Ngoko ke, i-ferrosilicon yinto ebalulekileyo ye-inoculant (ukunceda i-graphite ye-precipitate) kunye ne-agent ye-spheroidizing ekuveliseni i-nodular cast iron.

Ukongeza, isetyenziswa njenge-arhente yokunciphisa kwimveliso ye-ferroalloy.Ayisiyiyo kuphela indibaniselwano yeekhemikhali phakathi kwesilicon kunye neoksijini inkulu, kodwa kunye nomxholo wekhabhoni we-silicon ferrosilicon ephezulu iphantsi kakhulu.Ngoko ke, i-silicon ferrosilicon ephezulu (okanye i-siliceous alloy) yinto eqhelekileyo yokunciphisa i-agent yokunciphisa imveliso ye-low-carbon ferroalloy kwishishini le-ferroalloy.
