The Ultimate Buyer's Guide for Purchasing Ferro Silicon

1.What is ferrosilicon ?

Ferrosilicon (FeSi) is an alloy of silicon and iron. It is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel.

2.Properties of ferrosilicon

Ferro Silicon has a melting point of &#; to &#; with a boiling point of &#;and Ferro Silicon contains about 2% of calcium and aluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat-resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.

3. Which field is ferrosilicon used in ?

FeSi finds application in the steel manufacture and alloy production industry. It serves as a sprout or bud in the molding industry, contributes to the production of steel and cast iron. It is used to make improvements in granulation and metallic structure in the molding of non-alloy and alloy cast iron and restoration of different types of ferroalloy, such as nouvelle steel.

*Used as a deoxidizer and alloying agent in the steelmaking industry. To get qualified steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very high. So, ferrosilicon is a strong deoxidizer for steelmaking.

*Used as an inoculant and spheroidizing agent in the cast iron industry.

*Used as a reducing agent in low carbon iron alloys.

4.Common grades of ferrosilicon

 Among the various grades of ferrosilicon, the most widely used is 75% ferrosilicon. In the steelmaking industry, about 3-5 kg of 75% ferrosilicon is consumed for every 1 t of steel produced.

5.How to buy ferrosilicon?

In order to buy high quality and cheap ferrosilicon, we need to pay attention to the following points. 

*Cooperative manufacturers to ensure quality and stable supply.

*Rich experience in foreign trade.

*Knowing the ferrosilicon market one can buy the material at the right time. Since the price of ferrosilicon is affected by raw materials, electricity, supply and demand, and other factors. Therefore, in order to save costs, we recommend that traders with stable customers can purchase ferrosilicon in large quantities when the price is low. 

6.How to store ferrosilicon?

Ferrosilicon storage needs to pay attention to the following issues.

*Ferrosilicon is packed in ton bags when stored. The ton bags are made of high-quality plastic woven bags, which are moisture-proof and waterproof.

*The stacking height of the ferrosilicon should not be too high, 4-6 layers are better, if there is enough space, it is better to be within 4 layers.

*The ferrosilicon is tightly sealed, and the block ferrosilicon is a product of various shapes, which is easy to puncture the bag. Avoid rubbing the bag during loading and unloading.

*When ferrosilicon is stored under dry conditions, its oxygen content will change little, but when it is exposed to moisture in storage, it will have a serious tendency to oxidation. When the oxidized ferrosilicon is added to the molten steel, it will reduce its utilization rate, which means that will increase the amount of ferrosilicon, and produce more slag, thus increasing the cost.
