Hauv kev ua liaj ua teb steel ntau lawm, café cored hlau ua lub luag haujlwm tseem ceeb thiab yog cov khoom tseem ceeb rau kev txhim kho cov tawv hlau. Nws yog cov hlau xaim ua los ntawm cov wrapping calcium hlau hmoov nrog qee yam sib luag ntawm cov hmoov hlau hauv lub hlau stip. Qhov kev tsim qauv qauv tshwj xeeb no tso cai rau nws ua kom meej lub luag haujlwm hauv cov txheej txheem statmaking.

 

 

Cov calcium hlau cored hlau feem ntau yog siv rau ua kom ua kom cov roj carbon tsawg, cov hlau tsis muaj zog nrog cov qauv nruj ntawm daim ntawv thiab kom muaj nuj nqis. Nws cov cai ua hauj lwm yog ua raws li cov khoom ntawm calcium thiab hlau. Cov tshuaj calcium yog ib qho khoom hauv nws, thiab nws muaj kev muaj peev xwm muaj zog rau cov pa thiab leej faj. Thaum lub sij hawm steelmaking, calcium hlau cored hlau cored hlau yog pub rau hauv hlau av, thiab calcium reacts sai sai nrog cov pa roj oxygen sai sai nrog cov hlau loj. Calcium sib txuas nrog oxygen kom daim ntawv calcium oxide (cao), thiab sib xyaw nrog cov leej faj calcium sulfide (CAS). Cov tshuaj tiv thaiv no muaj qhov ntom ntom ntom ntom nti thiab yuav tshem tawm cov ntsiab lus ntawm kev phom sij hauv cov hlau thiab kev txhim kho cov hlau thiab txhim kho lub purity ntawm cov hlau.

 

 

Nyob rau tib lub sijhawm, calcium hlau cored hlau cored tuaj yeem kuj txhim kho morphology ntawm kev sib cais hauv cov hlau. Thaum cov tshuaj calcium tsis siv, cov suav nrog cov hlau yuav cuam tshuam ntev lossis cov duab tsis xwm yeem, uas yuav cuam tshuam cov kev ua tau zoo ntawm cov hlau, tshwj xeeb tshaj yog cov anisotropy. Calcium reacts nrog suav xws li Alumina hauv Molten Steel hlau, uas tuaj yeem ua rau lawv hloov mus ua cov ntaub ntawv thiab tus neeg mob hnyav ntxiv thiab cov neeg dawb huv. Qhov kev hloov pauv ntawm morphology thiab faib cov kev cuam tshuam nyuaj, cov khoom siv yas thiab ua haujlwm kub ruaj khov thiab txhim khu kev qha thaum ua thiab siv. Piv txwv li, daim ntawv thov ntawm cov calcium hlau cored hlau tshwj xeeb yog qhov tshwj xeeb ntawm cov hlau stainless, calcium-muaj cov cai tshwj xeeb rau cov khoom siv lub cev. Nws tuaj yeem zam kev tsim cov hlua ntev ntawm cov sulfide impurities, txhim kho lub anisotropy ntawm cov hlau, thiab paub meej tias cov hlau ua tau raws li kev yuav tsum tau ua tshwj xeeb.

 

 

Hauv ntej, calcium hlau cored hlau tau dhau los ua kev siv phom sij thiab muaj ntau yam zoo hauv kev siv nyiaj thiab kev kho kom zoo dua qub vim tias cov khoom siv tau zoo, thiab ntau yam khoom zoo txhim kho hauv kev lag luam steel.
