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 ye-smelting, ubuso bezinto eziphathekayo buxhomekeke kwi-crust kunye "nokubetha" (ukutshiza ubuso), 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
