Ferro Silicon Aluminum

Ferro silicon aluminum is one type of composite strong deoxidizer. For many years, It always adopt the aluminum cakes or aluminum ingot added into the steel-making furnace or ladle steel directly,this is the primary aluminum, which is not only costly, but aluminum is oxidized by oxygen in the air and slag to 70%-90% which caused excessive aluminum burnout and large fluctuations in residual aluminum content in molten steel.

Real Testimonials from Customers

20 days ago, I purchased 15 tons of metal silicon powder for the manufacture of refractory materials. After receiving the goods, they were inspected and met our requirements. Thank you for providing me with high quality metal silicon powder.
