Properties of Ferro Silicon
Ferro Silicon has a melting point of 1200°C to 1250°C with a boiling point of 2355°C and Ferro Silicon contains about 2% of calcium and aluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat-resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
Production of Ferro Silicon
A large portion of the global Ferro Silicon supply is manufactured in China, USA and India. The most basic definition of the Ferro Silicon production process would be that the silica (or sand) is mixed with coke, and then a reduction process takes place in the presence of millscale, scrap or another source of iron. A blast furnace is employed for Ferro Silicon production, but for larger contents of silica, an electric arc furnace is used. Ferro Silicon is usually supplied in bags of particles in pallet boxes or shrink-wrapped on pallets or in steel drums (50kg and dual layer plastic bags or 1000kg packed in drums). The granularity of particles varies from 10 mm to 100mm.
Uses of Ferro Silicon
There are many practical applications of Ferro Silicon to include carbon steel and stainless steel production, and when using the Pidgeon process to produce magnesium from dolomite. Applications in the production of other alloys include the manufacture of silicon steel for electro motors and cores, as well as coatings used during arc welding. One useful by-product of the production processes is silica fume, which is later added to concrete mixes to improve compressive and bonding strength there.
Ferro Silicon is an important as an additive to cast irons for controlling the initial content of silicon and in coming in contact with water, it may slowly produce hydrogen.
Ferro Silicon is
used for:
-
Steel making and foundries as a source of silicon in production of carbon steels, stainless steels, and other ferro alloys for its deoxidizing properties.
-
Used in manufacturing silicon steel for electro-motors and transformer cores.
-
It is used for inoculation of the iron.
-
To prevent loss of carbon from the molten steel.
-
In arc welding, ferro silicon can be found in some electrode coatings.
