Ferro-silicon products can be used in many industries such as steelmaking, foundry, other ferro-alloys, chemical industry, etc. The composition of ferrosilicon varies greatly from region to region. Silicon can increase the magnetic permeability of steel and reduce the hysteresis loss of steel. Therefore, FeSi has many advantages as an alloying agent.
Because silicon and oxygen readily combine to form silica, FeSi is often used as a deoxidiser in steelmaking. At the same time, because silicon releases a lot of heat, it deoxidises and raises the temperature of molten steel. Ferro-silicon is widely used as a reducing agent in the production of ferro-alloys and in the chemical industry. It therefore has a wide range of applications.
The production of FeSi is continuous. Depending on the discharge situation of the furnace, a small batch of materials is continuously added to the furnace and the alloy accumulated in the furnace is periodically discharged. The materials prepared for the furnace are accurately weighed according to the prescribed ratio. Dosing is carried out in a prescribed manner to ensure uniform mixing of the furnace materials. The density of the silica, the density of the steel scrap and the density of the raw materials shall be in appropriate proportions.
In order to ensure that the charge is uniformly mixed after descending from the tube, it is important whether or not the charge is uniformly mixed as this has a great influence on the melting. To ensure that the charge is evenly mixed Only one batch of material should be weighed at a time and no more than two batches of material should be stored for each material. Ferro-silicon can be melted continuously in large, medium and small immersion furnaces.
