Silicon calcium cored hlau yog cov khoom siv metallurgical feem ntau siv rau hauv cov txheej txheem steelmaking, uas feem ntau muaj silicon (Si) thiab calcium (Ca) ua cov khoom tseem ceeb, thiab yog qhwv nrog steel sawb lossis aluminium tawv ntawm txheej txheej. Hom tub ntxhais hlau no yog dav siv rau deoxidation, desulfurization thiab microalloying kev kho mob hauv steel ua, tshwj xeeb tshaj yog ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau zoo.
silicon calcium cored hlau muaj pes tsawg leeg thiab cov qauv
- Cov ntsiab lus tseem ceeb: Calcium-silicon alloy (feem ntau yog sib xyaw ntawm Si thiab Ca, nrog Si cov ntsiab lus feem ntau yog li ntawm 30% mus rau 60% thiab cov ntsiab lus Ca txog li 10% txog 30%).
- Txheej txheej txheej: steel sawb lossis txhuas daim tawv nqaij, siv los tiv thaiv kev ruaj ntseg ntawm calcium silicate alloy thaum khaws cia thiab siv, tiv thaiv oxidation thiab deliquescence.
calcium silicon cored hlau thov
Calcium silicate cored hlau muaj ntau yam kev siv hauv kev lag luam steelmaking, tshwj xeeb tshaj yog haum rau cov xwm txheej hauv qab no:
- Kev tsim cov hlau purity siab: xws li cov pa roj carbon tsawg, cov pa roj carbon tsawg tsawg, cov hlau tsis muaj steel thiab lwm cov qib siab xav tau steel.
- Kev tsim cov hlau alloy: Calcium silicate cored hlau yog siv los tswj cov kab hauv cov hlau thiab txhim kho kev ua haujlwm ntawm cov hlau alloy.
- Lub Hom Phiaj Tshwj Xeeb: xws li cov hlau hluav taws xob, cov kabmob steel, lub caij nplooj ntoos hlav steel thiab lwm yam steel qib uas yuav tsum tau muaj cov khoom siv siab thiab purity.
calcium silicon cored hlau zoo
- Cov nyhuv deoxidizing tseem ceeb: Kev sib xyaw deoxidizing nyhuv ntawm silicon thiab calcium ua rau nws muaj peev xwm tshem tawm cov pa tawm ntawm cov hlau kom zoo dua thiab txhim kho cov purity ntawm cov hlau.
- Txo cov naj npawb thiab qhov loj ntawm kev suav nrog: Los ntawm kev ua kom zoo dua cov kev suav nrog, nws txo qhov tsis xws luag hauv cov khoom siv thiab txhim kho qhov toughness, lub zog thiab lwm yam khoom ntawm cov hlau.
- Zoo desulfurization: Calcium zoo tshem cov sulfur los ntawm cov hlau molten, txhim kho cov tawv tawv thiab ua haujlwm ntawm cov hlau.
- Tus nqi siab: Piv nrog rau lwm cov ntsiab lus alloying, calcium silicate cored hlau muaj ntau dua deoxidation thiab desulfurization efficiency, thiab tib lub sijhawm, nws tuaj yeem txo cov khoom siv alloying thiab txhim kho kev lag luam ntawm kev tsim khoom.
