Performance and Features
Cast：
● It can nucleate in a wide temperature range, has a ability of strong spheroidizing and anti-recession. It also can effectively prevent the casting chill tendency.
● The deoxidation effect is relatively thorough, better than other deoxidation alloy, and the added amount is 35-50% of 75 ferrosilicon.
Steelmaking：
● When the FeSiBa alloy containing 10-35% barium is used for deoxidizing steelmaking, the utilization rate is high, the desulfurization ability is strong, which is superior to the silicon calcium alloy.
● Putting the right amount of silicon-barium alloy can improve the ductility and toughness at high and low temperatures. FeSiBa alloy is most effective for improving the cold resistance of steel.
Applications
It is widely used in steelmaking, cast steel and foundry industry to improve the quality of casting. It is an efficient and long-acting deoxidizer. It also has the effect of dephosphorization and desulphurization. It is especially suitable for casting of large thin-walled parts, uneven-walled parts, thin and rapid cooling.
