Si-Ca-Ba is an new and high efficient complex alloy of Ba Series;Can be used as deoxidizer and desulfurizer, and dephosphorization effect.
in Steel-making industry,for foundry it can be used as Inoculant and metamorphic agent .
Ba can effectively reduce the vapor pressure of Ca,increase the solubility of Ca in the molten steel; Compared with Si-Ca Alloy,use Si-Ca-Ba
alloy as the Ca source added into molten steel ,the added quantity of Ca is the half of Si-Ca alloy ‘s ,but the Ca content in the molten steel is
about double than Si-Ca alloy’s.and the stability of calcium in molten steel also improved significantly.
It is proved that Ba effectively protect Ca in molten steel,
reduce the oxidation of Ca, so as to meet the purpose
of handling calcium in molten steel.
