Silicon-barium alloy is an inoculant for casting and a deoxidizer for steelmaking. When used as an inoculant for casting, it can promote the formation of A-type graphite, refine the eutectic group, improve the distribution of graphite, and have strong anti-recession ability. And it can eliminate and prevent the whitening tendency of the casting and reduce the sensitivity of the section. When the silicon-barium alloy is used as a deoxidizer in steelmaking, there is no smoke and no spark, and the deoxidation effect is higher than that of the silicon-calcium alloy, and it can improve non-metallic inclusions. The shape of the material improves the quality of the steel.
use:
It is widely used in steelmaking, cast steel, and foundry industry. It is a high-efficiency and long-lasting deoxidizer. It also has desulfurization and dephosphorization effects. It is especially suitable for casting large thin-walled parts, uneven wall thickness and thin and small quenched parts. It can be used for Improve the quality of castings.
Performance and features:
1. The inoculant is suitable for gray cast iron and nodular cast iron, and can promote the formation of "A" type graphite and the integrity of graphite nodules.
2. It can nucleate in a wide temperature range, has strong spheroidizing ability and anti-recession ability, and can effectively prevent the whitening tendency of castings.
3. The deoxidation effect is relatively thorough, superior to other deoxidation alloy agents, and the added amount is 35%-50% of 75# ferrosilicon.
Steelmaking:
1. When silicon-barium alloy containing 10%-35% barium is used for deoxidation in steelmaking, it has high utilization rate and strong desulfurization ability, which is better than silicon-calcium alloy.
2. After the silicon-barium alloy is added, the nature and distribution characteristics of non-metallic inclusions in steel can be changed significantly.
3. Putting an appropriate amount of silicon-barium alloy into steel can improve the plasticity and toughness at high and low temperatures, and silicon-barium iron is the most effective for improving the cold resistance of steel.
