silicon alloys

The ferroalloys can be divided into three types include the silicon alloys, chrome alloys and manganese alloys, followings will describe more about the silicon alloys.

The first type need to describe is the ferro silicon alloy, it is one of the mainly and earliest product of ferroalloys, it has widely used in the industries such as steelmaking, ferroalloys, cast iron etc. In the steelmaking it can be used as deoxidizer and alloy additive, in the production of steel making, except for partially boiling steel, almost all steel grades are using ferrosilicon as a strong deoxidizer, what is more, adding some silicon in the steel can improve the strength, hardness and elasticity, adding some silicon into the steel can also improve the inversion rate,reduce hysteresis loss and eddy current loss;In the foundry industry, the ferro silicon can be used as inoculant and nodulizer, adding the ferro silicon into the cast iron can prevent to form carbide, promote graphite precipitation and spheroidization; In the ferroalloys industry, the ferro silicon will be used as the raw materials to product other composite ferroalloys.

There is the second of silicon alloy need to speak about the calcium silicon, it is always be used in the steel making as the deoxidizer, desulfurizer and warming agent, the silicon and calcium is great affinity for oxygen and sulfur, and the slag formed is easy to removed, now it can replace the aluminum for final deoxygenation. What is more, calcium silicon alloy can also be used in cast iron not only as deoxidizer and desulfurizer, but also be used as inoculant, compared with ferro silicon it can improve the performance of cast iron more effectively.

What is more, there are much more composite silicon alloys, such as silicon aluminum alloy,silicon aluminum barium alloy,silicon calcium barium alloy,ferro silicon barium alloy etc, they will be used as deoxidizer or desulfurizer for the steel making, increase the performance of steel, Anyang Huatuo Metallurgy can export several different types of silicon alloys for the steel making and casting, if you have any need or confused, welcome for your contact.
