Yuav ua li cas nrog lub silicon - calcium cored hlau ntawm hloov
Hauv qhov cub tawg ua kom sov, cov khoom siv tseem ceeb ntshiab calcium kab feem ntau siv los hloov cov txheej txheem ntawm cov kab mob calcium silicon kab, vim li cas? Vim li cas thiaj ua ib qho kev hloov pauv? Cia' s saib cov txheej txheem hauv kev nthuav dav.
Cov tshuaj tiv thaiv ntawm cov tub ntxhais txoj hlua ntshiab calcium hlau nrog molten steel yog qhov kev khaus ntau dua li ntawm silicon calcium hlau. Yog li ntawd, yuav tsum tau them nyiaj rau kev ua haujlwm ntawm kev kho mob calcium, xws li pub qhov tob thiab pub noj mov kom sai dua. Thaum lub sijhawm ua haujlwm rau cov khoom noj xaim hlau, cov khoom tseem ceeb ntawm cov ntshiab calcium hlau yuav tsum tau muab pub rau kom thiaj li tiv thaiv tau lub ntuj ntawm cov calcium vim tias lub vapor siab vapor siab ntawm cov tub ntxhais txoj kab ntshiab calcium calcium hlau.
Ib txoj kev yog los ua kom tuab ntawm cov ntawv hlau txhawm rau tiv thaiv nws lub cev tsis ntev los ntawm cuam tshuam rau kev tso tawm qhov tob ntawm calcium.
Lwm txoj hauv kev yog nce qib kev pub noj kom nce qhov tob ntawm calcium tso tawm, ntau dua kev pub mis ua rau cov khoom tseem ceeb ntawm calcium kab tuaj yeem nkag mus rau txheej slag thiab ncav cuag qee qhov tob, txo qhov oxidation ntawm slag rau Ca, nce qhov kev nqus ntawm molten steel rau Ca, txhim kho kev rov qab los ntawm Ca.
Kev pub ceev thiab kev pub mis noj yog qhov ntsuas qhov tseem ceeb ntawm cov txheej txheem pub mis ntawm cov khoom tub ntxhais ntshiab calcium hlau hlau. Lub vas nthiv lossis nrawm dhau kev pub mis ceev thiab lub cav xa khoom noj yuav cuam tshuam rau lub sijhawm melting thiab oxidation degree ntawm cov khoom tseem ceeb ntshiab calcium hlau, uas yuav cuam tshuam rau cov nyhuv metallurgical.
Tus neeg teb xov tooj yuav tsum xyuam xim rau qhov xwm txheej ntawm cov hlau nchuav hlau. Thaum cov hlau nchuav hlau yob kev ua phem, tus neeg teb xov tooj yuav tsum nres ib pliag ua ntej txuas ntxiv pub rau cov hlau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau.
Calcium silicate thread yog kho los ntawm tib lub tshuab, tab sis cov tshuaj lom neeg tsis tshua muaj zog, yog li kev ua haujlwm ntawm calcium silicate xov noj yog qhov yooj yim.
