Khoom Description
Seamless ntshiab calcium cored hlau yog tsim los ntawm ib txheej hlau txheej thiab ib sab hauv hlau ntshiab calcium hlau. Qee cov khoom kuj tseem yuav teeb tsa cov txheej txheem tiv thaiv ntawm cov hlau txheej thiab cov hlau calcium ntshiab, xws li txheej txheej txheej txheej txheej silicone roj rau saum npoo ntawm cov ntshiab calcium hlau thiab ziab nws. Cov qauv no ua rau lub seamless ntshiab calcium cored hlau kom cov calcium tivthaiv ruaj khov thaum pub cov hlau molten thiab tiv thaiv nws los ntawm oxidized los ntawm huab cua.
Seamless ntshiab calcium cored hlau tsis muaj qhov sib txawv ntawm cov khoom siv hlau, uas tuaj yeem tiv thaiv cov khoom los ntawm oxidized los ntawm huab cua thaum lub sij hawm cia thiab siv, yog li ua kom ruaj khov ntawm calcium Cheebtsam. Cov hlau ntshiab calcium hlau nrog cov tub ntxhais hauv cov khoom muaj cov calcium uas ruaj khov thiab txhim khu kev qha, uas tuaj yeem ua kom ruaj khov Ca / Al piv tom qab pub calcium hlau, yog li txhim kho cov nyhuv ntawm cov hlau molten.
Nyob rau hauv cov txheej txheem ntawm cov hlau pub, seamless ntshiab calcium cored hlau tuaj yeem noj ntawm qhov ceev ceev, kom cov calcium hlau tuaj yeem ncav cuag hauv qab ntawm lub ladle thiab tag nrho yaj thiab yaj, yog li txhim kho cov txiaj ntsig ntawm calcium. Raws li cov ntaub ntawv sau tseg, cov txiaj ntsig tuaj yeem ncav cuag 3 ~ 5 npaug ntawm cov hlau-calcium zoo tib yam, thiab cov txiaj ntsig ntawm cov hlau calcium tuaj yeem nce ntxiv ntawm 10% ~ 15% mus rau 30% ~ 50%. Kev siv cov kab noj qis qis tuaj yeem tiv thaiv qhov teeb meem tuag taus ntawm kev txaws loj thiab ua rau cov txheej txheem smelting ruaj khov. Oxygen thiab nitrogen nce thaum lub sij hawm kho calcium yog tsawg, thiab theem nrab oxidation ntawm molten steel thiab huab cua kuj raug zam, yog li txhim kho kev huv ntawm molten steel.
Ua kom tiav, seamless ntshiab calcium cored hlau yog ib qho ntxiv nrog rau daim ntawv thov tseem ceeb hauv cov hlau thiab hlau smelting. Los ntawm nws cov qauv tshwj xeeb thiab cov yam ntxwv ua tau zoo, nws ua lub luag haujlwm tseem ceeb hauv cov txheej txheem refining sab nraum qhov cub.
