company news about Ferro Silicon production

Ferro silicon is typically produced in submerged arc furnaces or electric arc furnaces using the following steps:

Raw materials preparation: The first step in ferro silicon production is the preparation of the raw materials. The main raw materials used are quartz (silica) and iron scrap or iron ore. These raw materials are crushed and mixed in the appropriate proportions.

Furnace charging: The mixture of raw materials is then charged into the furnace. The furnace is usually lined with refractory bricks to withstand the high temperatures and chemical reactions that occur during the process.

Heating and reduction: Once the furnace is charged, it is heated to the desired temperature using electric arcs or fossil fuel burners. The heat causes the raw materials to undergo a reduction reaction, in which the silicon in the quartz is reduced by the carbon in the iron to produce ferro silicon. The reaction takes place in the presence of a fluxing agent, such as limestone or dolomite, which helps to remove impurities from the metal.

Tapping and casting: Once the reaction is complete, the molten ferro silicon is tapped from the furnace and cast into molds or allowed to solidify into ingots. The castings are then cooled and broken into the desired size for shipment.

Post-production processing: The final step in ferro silicon production involves post-production processing, such as crushing, screening, and packaging, to prepare the material for shipping and use in various industries.
