Ferro silicon 75yog ib qho tseem ceeb alloy raw khoom, feem ntau yog siv nyob rau hauv steel smelting thiab alloy manufacturing. Cov khoom tseem ceeb yog silicon thiab hlau, thiab nws cov tshuaj muaj pes tsawg leeg feem ntau Si 70% -75% thiab Fe 20% -25%. Tsis tas li ntawd, nws feem ntau muaj me me ntawm carbon, aluminium, sulfur thiab lwm yam khoom.
Siv
Hlau smelting
Ferro silicon 75 yog siv los ua cov khoom siv hlau ntxiv los kho thiab txhim kho cov khoom sib xyaw thiab cov khoom ntawm cov hlau thaum lub sij hawm steelmaking txheej txheem, xws li nce cov silicon thiab carbon cov ntsiab lus thiab txhim kho lub zog thiab hardness ntawm hlau.
Alloy manufacturing
Ferro silicon 75 feem ntau yog siv rau hauv kev tsim cov hlau, xws li cov hlau tsis muaj steel, cov hlau tshwj xeeb, thiab lwm yam, los kho cov muaj pes tsawg leeg thiab cov khoom ntawm cov hlau.
Khoom thiab yam ntxwv
Lub zog thiab hardness
Vim tias qhov sib ntxiv ntawm silicon hauv Ferro silicon, lub zog thiab hardness ntawm cov hlau tuaj yeem txhim kho tau zoo.
Thaum tshav kub kub kuj
Ferro silicon 75 muaj kev ruaj ntseg zoo thiab kub tsis kam nyob rau hauv qhov kub thiab txias, thiab yog tsim rau siv nyob rau hauv kub kub smelting thiab ua cov txheej txheem.
Deoxidation
Cov silicon hauv Ferro silicon 75 tuaj yeem siv los ua lub zogdeoxidizerlos pab tshem tawm oxides los ntawm molten steel thiab txhim kho qhov zoo thiab nto tiav ntawm hlau.
Kev faib tawm los ntawm cov ntsiab lus carbon
Ordinary Ferro silicon:Cov ntsiab lus carbon feem ntau siab dua, feem ntau ntawm 0.5% thiab 2%. Hom Ferro silicon no tsuas yog siv rau hauv cov hlau smelting, uas tuaj yeem ua rau cov ntsiab lus ntawm silicon thiab carbon thiab txhim kho lub zog thiab hardness ntawm cov hlau.
Tsawg carbon Ferro silicon:Cov ntsiab lus carbon tsawg, feem ntau ntawm {{0}}.05% thiab 0.5%. Hom Ferro silicon no tsuas yog siv rau hauv kev tsim cov hlau tsis muaj steel, tshwj xeeb hlau thiab lwm yam alloys, thiab tuaj yeem tswj tau cov ntsiab lus carbon ntawm cov hlau zoo.
Ultra-tsawg carbon Ferro silicon:Cov ntsiab lus carbon tsawg heev, feem ntau tsawg dua 0.05%. Qhov no Ferro silicon yog siv nyob rau hauv smelting ntawm tshwj xeeb hlau, uas yuav txo tau cov pa roj carbon residue thiab xyuas kom meej cov kev ua tau zoo ntawm cov alloy.
Classification los ntawm Aluminium cov ntsiab lus
Tsawg aluminium Ferro silicon:Cov ntsiab lus aluminium yog tsawg, feem ntau tsawg dua 0.5%.
Medium Alumina Ferro silicon:Cov ntsiab lus txhuas yog nyob nruab nrab ntawm {{0}}.5% thiab 1.0%.
High aluminium Ferro silicon:Cov ntsiab lus txhuas yog qhov siab, feem ntau siab dua 1.0%.
Ferro silicon aluminium: Muaj cov ntsiab lus siab aluminium, feem ntau tshaj 30%. Ferro silicon feem ntau yog siv los ua deoxidizer, uas tuaj yeem tshem tawm cov oxides ntawm cov hlau molten thiab txhim kho cov hlau zoo.
Txhua hom Ferro silicon muaj nws cov kev siv tshwj xeeb thiab kev siv ntau yam. Ntau hom Ferro silicon raug xaiv los siv raws li kev xav tau tshwj xeeb.
