Ferro silicon aluminum alloy is a strong deoxidizer and a reducing agent for the production of other metals and alloys. It is also used for thermite welding, the manufacture of exothermic agents and explosives, etc.
Particle Size: 35mm, 40mm, 50mm, etc.
Package: 1Mton big bag.
The use of ferro silicon aluminum alloy for deoxidation has proved its good effect in practical applications. Compared with aluminum deoxidation, not only the yield of aluminum is high, the amount of residual aluminum is easy to control, and the shape of inclusions is also improved.
The element recovery rate of silicon aluminum alloy is high, mainly because the alloy has a large specific gravity, aluminum has a specific gravity of 2.7g/cm3, and ferro silicon aluminum(FeAl30Si20) has a specific gravity of 3.5-4.2g/cm3. The specific gravity of the steel making residue is generally 2.8-3.2g/cm3, so the ferro silicon aluminum alloy will sink below the scum after being added, which effectively controls the reaction of aluminum with air and oxygen in the slag.
It is generally believed that the good deoxygenation effect is due to the formation of complex deoxygenation products and the reduced oxide activity, which is beneficial to the progress of the deoxidation reaction. In addition, low-melting-point phases are easy to generate, which makes inclusions easy to polymerize and promotes the floating and removal of deoxidized products.

Ferro silicon is widely used as deoxidizer and alloy additive in steel making, and also can be used as an inoculant and nodulizer for cast iron. Ferro silicon powder or atomized ferro silicon powder can be used as coating for welding rod production.
Ferro silicon barium is suitable for inoculation treatment of gray cast iron or ductile iron with strict requirements on air tightness or leakage. Ferro Silicon Barium is easier to dissolve and absorb than ordinary inoculants, and can reduce the gas content in molten iron.
Rare earth magnesium ferro silicon alloy refers to an alloy made of ferro silicon, calcium, magnesium, rare earth, etc. through melting configuration. It is a good spheroidizing agent with strong deoxidation and desulfurization effects.
