Koj puas tau hnov CaSi cored hlau? Tsis yog, nws tsis yog hom tshiab spaghetti, tab sis yog cov khoom siv tseem ceeb siv hauv kev lag luam metallurgical. Raws li lub tuam txhab tshwj xeeb hauv metallurgy, peb muaj kev txawj ntse heev hauv kev tsim cov CaSi cored hlau.
Ua ntej, cia peb tham txog dab tsi CaSi cored hlau siv rau. CaSi sawv cev rau Calcium Silicon, uas yog cov hlau ua los ntawm calcium, silicon, thiab hlau. Cov hlau no yog siv los deoxidize thiab desulfurize molten steel, uas ua rau kom muaj kev txhim kho tag nrho ntawm cov khoom kawg. CaSi cored hlau yog ib lub kauj ntawm cov hlau nrog lub hollow core, ntim nrog CaSi alloy. Nws yog ib txoj hauv kev yooj yim ntawm kev ntxiv cov hlau rau cov hlau molten, nrog rau qhov tseeb thiab tswj tau ntau npaum li cas.
Yog li, peb yuav ua li cas CaSi cored hlau? Zoo, nws yog me ntsis ntawm cov txheej txheem. Ua ntej, peb pib los ntawm melting cov ntshiab calcium thiab silicon nyob rau hauv ib tug induction rauv. Tom qab ntawd cov kua alloy yog tov nrog hlau hmoov thiab ncuav rau hauv graphite pwm. Tom qab cov pwm txias, peb tshem tawm cov khoom hlau thiab zuaj nws mus rau hauv me me pellets.
Cov kauj ruam tom ntej yog sau lub hollow core ntawm cov hlau nrog cov crushed pellets. Qhov no yog ua los ntawm kev siv lub tshuab tshwj xeeb uas pub cov hlau thiab cov pellets ib txhij. Cov hlau yog coated nrog ib txheej tiv thaiv kom tsis txhob oxidation thaum thauj thiab khaws cia.
Voila, peb tam sim no muaj ib lub kauj ntawm CaSi cored hlau! Tab sis ua ntej peb tuaj yeem muag nws, peb yuav tsum xyuas kom meej tias qhov zoo yog nce mus txog par. Peb sim txhua pawg ntawm CaSi cored hlau rau nws cov tshuaj muaj pes tsawg leeg, hlau txoj kab uas hla, thiab filling piv. Peb xav kom peb cov neeg muas zaub tau txais cov khoom zoo ib yam thiab txhim khu kev qha.
Raws li lub tuam txhab muaj keeb kwm ntev hauv kev lag luam metallurgical, peb txaus siab rau peb cov txheej txheem tsim khoom thiab qhov zoo ntawm peb cov CaSi cored hlau. Nws yog ib qho txiaj ntsig zoo thiab muaj txiaj ntsig ntawm kev ntxiv ib qho tseem ceeb alloy rau molten steel, uas ua rau cov khoom zoo dua zaum kawg. Yog li, lwm zaus koj pom ib daim hlau ci, nws tsuas yog ua tsaug rau peb CaSi cored hlau.
