1. Cov tswv yim thiab kev siv cov cam khwb cia hlau thiabferrosilicon
Cam khwb cia hlau yog ibhlau alloycov khoom uas muaj cov pa roj carbon ntau, silicon thiab lwm yam hlau. Nws muaj castability zoo thiab yog dav siv nyob rau hauv ntau yam mechanical qhov chaw, yeeb nkab fittings, tsheb qhov chaw thiab lwm yam teb nyob rau hauv industrial ntau lawm. Ferrosilicon tseem yog ib qho ntawm cov khoom siv ferro alloy, muaj cov feem ntau ntawm cov khoom silicon, thiab feem ntau yog siv hauv steelmaking thiab casting ntau lawm.
2. Qhov ntau npaum li cas ntawm cam khwb cia hlau thiab ferrosilicon
Hauv kev tsim khoom, qhov kev faib ua feem ntawm cov hlau cam khwb cia thiab ferrosilicon yog qhov tseem ceeb heev. Kev siv qhov sib txawv ntawm qhov sib txawv yuav cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm cov casting. Raws li ib txwm muaj, qhov ntau npaum li cas ntawm ferrosilicon tso nyiaj rau qhov sib piv me me hauv kev tsim cov casting, txog 1-3% ntawm cov hlau cam khwb cia, thiab tuaj yeem tsim nyog ntxiv rau qee kis. Qhov sib ntxiv ntawm ferrosilicon tuaj yeem txhim kho cov khoom siv kho tshuab, hnav tsis kam thiab corrosion tsis kam ntawm cov hlau cam khwb cia, ua rau cov castings muaj zog thiab ruaj khov.
3. Yog vim li cas rau kev noj ntau npaum li cas
Qhov ntau npaum li cas ntawm cov cam khwb cia hlau thiab ferrosilicon feem ntau yog nyob ntawm cov kev xav tau ntau lawm thiab alloy muaj pes tsawg leeg. Hauv kev tsim khoom, kev siv thiab kev ua haujlwm yuav tsum tau xav txog. Yog hais tias cov khoom siv xws li toughness thiab gripability ntawm casting yuav tsum tau txhim kho, qhov ntau npaum li cas ntawm ferrosilicon yuav tsum tau nce; Yog hais tias lub hardness thiab hnav tsis kam ntawm cov casting yuav tsum tau txhim kho, cov tshuaj ferrosilicon yuav tsum tau txo. noj npaum li cas.
4. Cov ntsiab lus
Hauv kev tsim cov casting, qhov kev faib ua feem ntawm cov cam khwb cia hlau thiab ferrosilicon yuav tsum tau hloov kho raws li cov kev xav tau ntau lawm thiab kev ua tau zoo, kom qhov zoo thiab kev ua tau zoo ntawm cov castings tuaj yeem ua tau raws li qhov yuav tsum tau ua. Tsis tas li ntawd, hlau alloy cov ntaub ntawv xws li cam khwb cia hlau thiab ferrosilicon yuav tsum tau muab khaws cia thiab siv thaum lub sij hawm casting txheej txheem los xyuas kom meej cov khoom zoo thiab kev siv cov teebmeem.
