Description

Silicon-Calcium-Barium Alloy for steel-making

Si-Ca-Ba is an new and high efficent complex alloy of Ba Series;Can be used as deoxidizer and dusulfurizer, 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,useBa-Ca-Ba alloy as the Ca source added into molten steel ,the added quatity of Ca is the half of Si-Ca alloy ,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.
