I. Introduction to Ferrosilicon 72:
A ferro alloy composed of silicon and iron is Ferro Silicon. The silicon content in this ferro alloy is between 15% and 90%. There is high proportion of iron silicide in it. Other elements present in Ferro Silicon are calcium and aluminium. This corrosion and abrasion resistant ferro alloys is silvery grey to dark grey in color. Its particles are available in different forms, like milled, crushed and lumps. It might react with water for hydrogen production. Some of the largest producers of this odorless Ferro Silicon are India, USA and China, responsible for global supply.
Ii. Smelting Method:
Ferrosilicon 72 is made from coke, steel chips, quartz (or silica) and smelted in an electric furnace.Traditionally, ferric silicon is made by reducing the silicon from the silica containing SIO2.Most smelting of ferrosilicon uses metallurgical coke as reducing agent, and steel chip is the regulator of ferrosilicon.

Iv. Ferro silicon Applications
Ferro silicon is a great source of silicon, which is why it is used for reducing metals for their oxides and deoxidizing steel & other ferrous alloys.
Several ferro alloys can be made using ferro silicon.
Silicon can be manufactured along with silicon steel and ferrous silicon alloys that are resistant to corrosion and high temperature.
In the cast iron manufacturing, ferro silicon is used in iron inoculation process to increase graphitization.
It is used in electrode coatings in arc welding.
It can be used as an additive to cast irons to control the initial silicon content.
Magnesium ferrosilicon (MgFeSi) is a prealloy which can be manufactured for the production of ductile iron.
Magnesium from dolomite can be made in the Pidgeon process with the use of Ferro silicon.
It can also be used in the production of carbon steel, silicon steel and stainless steel.
It is used in metallurgical industry for different processes and reactions.
Electric industry buys this ferro alloy to use it as a source of pure silicon.
Chemical industry use it for the production of silicon copper.
V. Special Reminder:
A metal compound containing a small amount of phosphorus in ferrosilicon, which can release phosphine when exposed to moisture in transportation and storage, resulting in poisoning of the population and death in severe cases.
Vi. Packaging;
Tons bag packing, 1000kg/ bag
Vii. Delivery Time:
Delivery within 10 days upon receipt of advance payment.
Viii. Tips:
Customers often ask how to store ferrosilicon 72?In fact, like other ferrosilicon products, the most important is to do moistureproof treatment, in order to improve the efficiency of ferrosilicon use.
