Calcium los ntawm calcium-silicon cored hlau yog cov khoom siv feem ntau siv cov hmoov hmoov. Txawm hais tias nws yog ib qho deoxidiser muaj zog, nws muaj qhov tshwj xeeb tsis tshua muaj lub ntiajteb txawj nqus thiab cov ntsiab lus melting tsis tshua muaj, thiab nws yooj yim rau kev tsim npuas ntawm qhov kub thiab txias. Yog li ntawd, yog tias calcium hlau siv ib leeg los ua cov hmoov txheej ntawm cov hlau cored, cov hlau cored yuav pib hlawv sai li sai tau thaum nws tau noj rau hauv qhov cub ua kom zoo dua lub qhov cub ua kom zoo, nws yuav pib hlawv. Yog hais tias cov hlau cored tsis ncav cuag hauv qab nruab nrab ntawm cov hlau molten, cov nyhuv purification xav tau tsis tuaj yeem ua tiav.
Txawm hais tias kev ntsuas xws li siv cov ntaub ntawv kub-resistant sheath thiab siv ceev nrooj, nws tsis tuaj yeem tiv thaiv kom tsis txhob hlawv. Nyob rau tib lub sijhawm, kev sib xyaw ntawm cov hmoov txheej hauv cov txheej txheem ua haujlwm no yuav tsis ua tiav qhov kev xav tau kev lim dej, thiab nws tseem yuav ua rau cov khoom siv calcium uas kim dua.
