Ferrosilicon72

Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel scrap, quartz(or silica) as raw materials and smelted in an electric furnace. Because silicon and oxygen can be easily synthesized into silicon dioxide, ferrosilicon is often used in steelmaking as a deoxidizer, while the generation of SiO2 due to the release of a large amount of heat, in the deoxidation at the same time, the temperature of the steel is also beneficial to improve. At the same time,ferrosilicon can also be used as an alloying element adding agent, widely used in low-alloy structural steel, spring steel,bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in the production of ferroalloys and chemical industry, commonly used as a reducing agent.

Product Description

INTRODUCTION

Uses of Ferrosilicon 72:

(1) Ferrosilicon 72 is an essential deoxidizer in the steel industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.

(2) Ferrosilicon 72 is used as an inoculant and spheroidizing agent in the cast iron industry. In the production of nodular cast iron, ferrosilicon 72 is an important inoculant (helping to precipitate graphite) and nodulizer.

(3) Ferrosilicon 72 is used as a reducing agent in the production of ferroalloys. Not only is the chemical affinity between silicon and oxygen great, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a commonly used reducing agent in the production of low-carbon iron alloys in the ferroalloy industry.

(4) Ferrosilicon 72 is often used in the high temperature smelting process of magnesium metal according to the Pidgeon method of magnesium smelting. The magnesium in CaO. MgO is replaced, and each ton of magnesium metal will consume about 1.2 tons of ferrosilicon. The production of magnesium metal plays an important role.
