Ferrosilicon is an ferro alloy composed of iron and silicon. The color of ferro silicon is gray. According to the content of Si, Fe, Al, etc., it is divided into different grades. 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.
Ferro silicon has two kinds of blocks and powders. Common particle sizes are 0-3mm, 10-60mm, 10-100mm, etc. Manufacturers and suppliers can be customized according to user requirements.
