Kev siv Calcium Hlau hauv Steelmaking Kev Lag Luam

Calcium hlau muaj ib daim ntawv thov tseem ceeb hauv kev lag luam steelmaking, uas tuaj yeem txhim kho kev ua tau zoo thiab zoo ntawm cov hlau.
1. Calcium kho tus neeg saib xyuas: hlau calcium feem ntau yog siv los ua tus neeg saib xyuas calcium hauv cov txheej txheem steelmaking.Los ntawm kev ntxiv cov hlau calcium uas tsim nyog rau hauv lub tshuab ua hlau, cov pa oxygen impurities xws li oxides, sulfides thiab nitrides hauv cov hlau molten tuaj yeem raug tshem tawm zoo, yog li txhim kho cov purity ntawm cov hlau molten.
2. Deoxidizer: Calcium hlau kuj tuaj yeem siv los ua deoxidizer hauv cov txheej txheem steelmaking.Thaum lub sij hawm smelting txheej txheem, los ntawm kev ntxiv metallic calcium rau molten steel, calcium tuaj yeem hnov ​​​​mob nrog oxygen hauv molten steel los tsim calcium oxide, thiab hnov ​​​​mob nrog impurities nyob rau hauv muaj pes tsawg leeg los tsim oxides, zoo txo ​​cov yaj cov pa oxygen thiab txhim kho cov nyhuv deoxidation ntawm hlau. .
3. Modifier: Calcium hlau kuj tuaj yeem siv los ua tus hloov kho los txhim kho cov qauv siv lead ua thiab cov khoom siv ntawm cov hlau.Nyob rau hauv cov txheej txheem steelmaking, hlau calcium tuaj yeem hnov ​​​​mob nrog silicon, aluminium thiab lwm yam hauv cov hlau molten los ua cov carbides thiab silicides zoo ib yam li calcium oxide, refine cov khoom, thiab txhim kho lub zog thiab toughness ntawm hlau.
4. Alloy additives: Calcium hlau kuj tseem siv tau los ua alloy additives hauv steel los txhim kho thiab kho cov tshuaj muaj pes tsawg leeg thiab cov khoom ntawm cov hlau.Raws li kev xav tau, cov hlau calcium uas tsim nyog tuaj yeem muab ntxiv rau cov hlau los kho cov ntsiab lus ntawm silicon, hloov cov martensitic kub ntawm cov hlau, thiab ua kom cov hardness.
Calcium hlau ua lub luag haujlwm tseem ceeb hauv kev lag luam steelmaking, txhim kho cov khoom zoo thiab cov khoom ntawm cov hlau.Los ntawm kev siv cov tshuaj calcium kev kho mob, deoxidizers, modifiers thiab alloy additives, purity, deoxidation nyhuv, siv lead ua qauv thiab txhua yam khoom ntawm hlau tuaj yeem txhim kho tau zoo kom tau raws li cov kev xav tau ntawm cov hlau hauv ntau daim ntawv thov.
