Ferrosilicon 70 is a ferrosilicon alloy with a silicon content of about 70%. FeSi 70 is an ferro alloy with iron and silicon as the main components. The silicon content is generally about 70%, and the rest is mainly iron. It may also contain a small amount of impurity elements such as aluminum, calcium, manganese, phosphorus, and sulfur. It is usually in lump or granular form, with a silver-gray metallic luster on the surface. It has strong reducing properties and can react with a variety of metal oxides at high temperatures to reduce metals from their oxides. Chemical reactions may occur in humid environments or in the presence of corrosive media such as acids and alkalis. The silicon in 70 ferrosilicon has a large chemical affinity with oxygen and is easily combined with oxygen to form silicon dioxide.

Products Application

Deoxidizer:

It is a commonly used deoxidizer in the steelmaking process, which can effectively remove oxygen from molten steel and reduce oxide inclusions in steel.

Alloy additives:

It can improve the strength, hardness, elasticity and toughness of steel. The production of structural steel, spring steel, bearing steel, etc. requires the addition of ferrosilicon 70 to adjust the composition of steel.

Inoculant:

In cast iron production, it can be added to molten iron as an inoculant to promote graphitization and improve the morphology and distribution of graphite.

Ferroalloy production:

It can be used as a reducing agent to produce other ferroalloys, such as in the production of ferromolybdenum, ferrotungsten, etc.

Chemical industry:

It can be used to manufacture silicone and other products in the chemical industry.

Welding rod manufacturing industry:

Can be used as one of the coating components of welding rods, which helps to improve the welding performance and weld quality of welding rods.
