Calcium Silicon Barium is the good deoxidizer and desulfurizer. In the process of deoxidation , silicon ,calcium and barium , three elements promote each other , improve the utlilzation rate .It can make the oxygen content in steel to a minimum. Recovery rate of Si, Ca and Ba is higer than other alloy .At the same time it can make the other complex oxide easy to rise from the liquid steel ,purifying liquid steel ,improve the impact toughness of steel and machining perfoemance.
