Featured Products Ferro Silicon 72

Ferro Silicon 72：The main use of ferrosilicon 72 is as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel and other varieties, but also can be used as a inoculant for the manufacture of ductile iron and malleable cast iron.

1.Ferro silicon 72 is one of the important raw materials in the iron and steel industry, and the output, quality and variety of ferroalloy are directly related to the quality of steel and its products.

2.In making Ferro Silicon 72, when smelting medium carbon steel, ferrosilicon needs to be added to the molten steel, which can effectively deoxidize and also act as an alloying agent to improve the performance of the steel. In casting production, when casting iron castings with low phosphorus and low sulfur, ferrosilicon can be added as an inoculant to effectively promote the precipitation and nodularization of graphite and improve the performance of cast iron.

3.The quality of ferro silicon 72 products is stable and good, and the smelting process can reduce the production cost of silicon, reduce energy consumption and improve the service life of the furnace.

4.The production of ferro silicon 72 is to produce ferrosilicon 72 by using three raw materials: silica, blue carbon or coke, and iron oxide under conventional smelting conditions. It is the organic combination of iron oxide scale and the escape gas from the furnace mouth to promote the violent reduction reaction of SiC. It increases the air permeability of the charge, eliminates SiC and SiO2 and insoluble substances at the bottom of the melt pool, and creates favorable conditions for the deep insertion of electrodes and the expansion of the crucible.
