Calcium siliconyog cov khoom siv raw khoom siv feem ntau siv hauv cov txheej txheem steelmaking. Nws feem ntau muaj nyob rau hauv daim ntawv ntawm calcium silicon alloy. Cov hauv qab no yog kev taw qhia thiab kev siv tseem ceeb ntawm calcium silicon steelmaking raw cov ntaub ntawv:
Muaj pes tsawg leeg thiab cov khoom ntawm calcium silicon
Calcium silicon alloy feem ntau muaj ob lub ntsiab: silicon (Si) thiab calcium (Ca). Feem ntau cov ntsiab lus silicon yog nyob nruab nrab ntawm 28% - 35% thiab cov ntsiab lus calcium nyob nruab nrab ntawm 55% - 60%. Qhov tshwj xeeb muaj pes tsawg leeg yuav nyob ntawm tus neeg tsim khoom. Nws txawv nyob ntawm cov khoom specifications.
yam ntxwv
1. Muab cov khoom silicon thiab calcium:Calcium silicon alloy tsuas yog muab ob lub ntsiab lus tseem ceeb, silicon thiab calcium. Cov ntsiab lus no muaj kev cuam tshuam loj rau cov txheej txheem smelting thiab lub cev kawg ntawm cov hlau.
2. Yooj yim rau yaj thiab txheej txheem:Calcium silicon alloy tuaj yeem sib npaug sib npaug thiab nrawm nrawm nrog cov hlau molten thaum yaj, uas yog qhov tsim nyog rau kev hloov kho sai thiab tswj cov txheej txheem alloying.
Kev siv lub ntsiab ntawm calcium silicon hauv steelmaking
1. Deoxygenation thiab desulfurization:
Deoxidation:Calcium silicon alloy ua raws li kev txo tus neeg sawv cev hauv cov hlau smelting thiab tuaj yeem hnov mob nrog hlau oxide los tsim SiO₂ thiab CaO, uas yuav pab txo qis cov pa oxygen hauv cov hlau molten, yog li txo cov teebmeem ntawm oxides ntawm cov hlau.
Cov nyhuv desulfurization:Calcium silicon alloy kuj muaj qee yam desulfurization muaj peev xwm, uas tuaj yeem txo cov sulfur (S) hauv cov hlau molten rau hauv cov roj hydrogen sulfide (H₂S), txo cov sulfur cov ntsiab lus hauv cov hlau, thiab txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov hlau. . kev ua tau zoo.
2. Kho qhov muaj pes tsawg leeg ntawm molten steel:tswj alloying: Raws li cov khoom siv ntxiv, silicon-calcium alloy tuaj yeem tswj cov silicon thiab calcium hauv cov hlau molten kom ua tau raws li cov hlau sib txawv thiab cov kev xav tau ntau lawm, thiab kho cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov hlau molten.
3. Txhim kho steel zoo:Txhim kho lub cev muaj zog: Los ntawm kev tswj cov txheej txheem alloying zoo, calcium silicon alloy tuaj yeem txhim kho lub zog, hardness, hnav tsis kam thiab lwm yam khoom siv lub cev ntawm cov hlau, ua rau cov khoom kawg ua tau zoo dua hauv ntau daim ntawv thov.
Raws li ib qho tseem ceeb ntawm cov khoom siv raw hauv cov txheej txheem steelmaking, calcium silicon tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau los ntawm muab ob qho tseem ceeb, silicon thiab calcium. Nws yog tsuas yog siv los deoxidize, desulfurize thiab kho cov muaj pes tsawg leeg ntawm molten steel. Nws yog ib qho tseem ceeb alloys dav siv nyob rau hauv niaj hnub steel kev lag luam.
