Usuku lweKrisimesi
Ixesha leKrisimesi lifikile.Ndiyathemba ukuba ube noNyaka oMtsha omangalisayo.Ngamana yonke imihla ingabamba iiyure ezimnandi kuwe.
Nyumisa
I-silicon ephezulu ye-ferrosilicon inyibilikiswa kwiziko lombane elicuthayo kunye ne-carbon lining, isebenzisa i-silica, iifayili zentsimbi (okanye izikali zentsimbi), kunye ne-coke njengezinto eziluhlaza.Ukunyibilikiswa kwesithando sombane se-ferrosilicon yindlela yasimahla ye-slag, kwaye izinto ezikrwada kufuneka zicoceke kwaye zingabi naludaka, isanti, kunye nobunye ukungcola.Ukongeza iinkuni zokhuni kunye namalahle kwizinto zesithando somlilo kunokuphucula ukusebenza kwayo.Ngethuba lenkqubo yokunyibilika, ubuso bezinto eziphathekayo buxhomekeke kwi-crust and "stinging" (surface spraying), kwaye kuyimfuneko rhoqo "ukubetha isithando somlilo".Isithando somlilo sivelisa i-silicon iron rhoqo kwiiyure ezi-2-4 kwaye siyibumba ibe yi-ingots ezinobunzima obungaphantsi kwe-100 millimeters.Ukunyibilikiswa kwe-ferrosilicon ngokuqhelekileyo kuthatha iziko lombane elivulekileyo.Kwiminyaka yakutshanje, ukuze kuthintelwe ukungcoliseka kwendalo, "i-hood ephantsi" okanye "i-semi enclosed" iziko zombane ziye zasetyenziswa ngokuqhelekileyo, ezilungele ukubuyisela amandla obushushu kunye nokuphelisa umsi nothuli;Ukuveliswa kwesilicon ferrosilicon ephezulu (equlathe ngaphezu kwe-75% yesilicon) ubukhulu becala iqhutywa kusetyenziswa isithando sombane esijikelezayo ukunciphisa ukungcangcazela kwesithando somlilo.
Injongo
1. Isetyenziswe njenge-inoculant kunye ne-spheroidizer kwishishini lentsimbi.Intsimbi yentsimbi yinto ebalulekileyo yentsimbi kwishishini lanamhlanje.Ixabiso eliphantsi kunentsimbi, kulula ukunyibilika kunye nokunyibilika, kwaye inokusebenza okugqwesileyo kokusa kunye nokuxhathisa okungcono kwenyikima kunentsimbi.Ngokukodwa i-iron ductile, iimpawu zayo zomatshini zifikelela okanye zisondele kwezo zentsimbi.Ukongeza inani elithile le-ferrosilicon ukuphosa isinyithi kunokuthintela ukubunjwa kwe-carbides kwintsimbi, ukukhuthaza 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.
2. I-Ferrosilicon isetyenziswa ngokubanzi kwi-industry yensimbi, i-industry casting, kunye neminye imveliso yemveliso.I-Ferrosilicon yi-deoxidizer ebalulekileyo kwishishini le-steelmaking.Kwi-steelmaking, i-ferrosilicon isetyenziselwa i-precipitation deoxygenation kunye ne-diffusion deoxygenation.Intsimbi yentsimbi yezitena iphinda isetyenziswe njenge-alloying agent ekwenzeni intsimbi.Ukongeza inani elithile le-silicon kwintsimbi kunokuphucula kakhulu amandla ayo, ukuqina, kunye nokunwebeka, ukonyusa amandla ayo ombane, kunye nokunciphisa ilahleko ye-hysteresis yentsimbi yesiguquli.I-aluminium ephantsi ye-ferrosilicon luhlobo olukhethekileyo lwe-ferrosilicon oluye lwavela kwiminyaka yamuva.Inkqubo yokunyibilika kwayo iyinkimbinkimbi kwaye ixabiso elongezelelweyo lemveliso liphezulu, eliyindawo ephononongwa ngokusebenzayo ngabavelisi abahlukeneyo be-ferrosilicon.
Iitoni ezingama-300 ze-ferrosilicon eziza kuthunyelwa
