Calcium Silicon Cored Hlau yog ib hom hlau ladle refining khoom rau metallurgy, uas yog ua los ntawm calcium silicate alloy hmoov raws li cov khoom tseem ceeb, thiab txheej txheej yog them nrog steel daim tawv nqaij. Nws yog dav siv nyob rau hauv refining txheej txheem ntawm hlau nyob rau hauv metallurgical kev lag luam, tsuas yog rau deoxidation, desulfurization thiab tshem tawm impurities nyob rau hauv steel los txhim kho qhov zoo thiab kev ua tau zoo ntawm hlau.
calcium silicon Cored hlau daim ntaub ntawv
1. Deoxygenation: Silicon thiab calcium Cheebtsam nyob rau hauv silica-calcium cored hlau yog muaj zog deoxidizers. Lawv hnov mob nrog oxygen hauv cov hlau los tsim cov oxides ruaj khov, yog li txo cov pa oxygen hauv cov hlau thiab tiv thaiv cov oxide nyob hauv cov hlau.
2. Desulfurization: Calcium muaj peev xwm desulfurization zoo, thiab tuaj yeem ua rau cov sulfur hauv cov hlau los tsim cov calcium sulfide, yog li tshem cov sulfur hauv cov hlau, txo cov sulfur cov ntsiab lus hauv cov hlau, tiv thaiv thermal embrittlement, thiab txhim kho steel toughness.
3. Fine inclusions: Calcium tuaj yeem hloov cov morphology ntawm inclusions nyob rau hauv steel, ua rau nws ua spherical los yog zoo hais, faib yog ntau uniform, yog li txhim kho cov neeg kho tshuab zog thiab kev ua tau zoo ntawm steel.
4. Txhim kho cov kua steel fluidity: Kev siv cov calcium silicate core hlau tuaj yeem txhim kho cov kua steel fluidity thiab txo qhov tsis xws luag uas tshwm sim hauv cov txheej txheem casting, xws li shrinkage, porosity, thiab lwm yam, yog li txhim kho qhov zoo ntawm castings.
calcium silicon cored hlau zoo
- Kev tswj xyuas meej: Calcium-silicon core hlau tuaj yeem tswj hwm cov nyiaj calcium thiab silicon ntxiv los ntawm cov xaim feeder, thiaj li ua rau kev faib cov ntsiab lus alloying hauv cov hlau molten ntau dua, zam qhov tsis sib xws uas yuav tshwm sim nyob rau hauv txoj kev ib txwm muaj. ntawm kev ntxiv.
- Cov tshuaj tiv thaiv zoo: Kev siv cov tub ntxhais hlau ua kom cov calcium thiab silicon hnov mob tag nrho hauv cov hlau, txo lub sijhawm cov tshuaj tiv thaiv thiab txhim kho kev ua kom zoo dua qub.
- Txo cov khib nyiab: Cov tub ntxhais hlau qhia cov ntsiab lus alloying ncaj qha rau hauv cov hlau molten, txo cov khoom pov tseg thiab cov pa phem.
Calcium silicon cored hlau txheej txheem
Cov txheej txheem ntau lawm ntawm calcium-silicon cored hlau muaj qhov sib npaug ntawm cov calcium-silicon alloy hmoov rau hauv cov tawv nqaij steel, uas yog tom qab ntawd npog thiab nias rau hauv cov duab los ntawm cov cuab yeej tshwj xeeb. Nws thiaj li, ib tug nruam hlau yog tsim, uas yog ib qho yooj yim mus siv nyob rau hauv lub steelmaking txheej txheem.
Calcium silica cored hlau plays lub luag haujlwm tseem ceeb hauv kev lag luam steel, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hlau zoo, nws tuaj yeem txhim kho qhov purity thiab kev ua tau zoo ntawm cov hlau, thiab tau siv dav hauv kev tsim cov hlau hauv kev tsim kho, tsheb, nkoj tsim. , machinery manufacturing thiab lwm yam lag luam.
