INTRODUCTION
Silico manganese is a alloy of manganese silicon and Iron with small percentage of carbon and several elements. The silico Manganese have an important influence on the properties of steel depending on the amount added and the combined effect with other alloying metal. It has a strong affinity for oxygen and act as deoxidizer and play an important role in the manufacturing of steel as deoxidizing, desulphuring and alloying agents silico manganese is used as alloying elements in manufacturing of spraying steel, transformer steel and other type of alloy steels.
Silico manganese is a metallic ferroalloy composed principally of manganese, silicon, and iron. It is produced in a number of grades and sizes and is consumed in bulk form primarily in the production of steel as a source of both silicon and manganese, although some silicomanganese is used as an alloying agent in the production of iron castings. Manganese, intentionally present in nearly all steels, is used as a steel desulfurizer and deoxidizer. By removing sulfur from steel, manganese prevents the steel from becoming brittle during the hot rolling process. In addition, manganese increases the strength and hardness of steel. Silicon is a deoxidizer, aiding in making steels of uniform chemistry and mechanical properties. As such, it is not retained in the steel, but forms silicon oxide, which separates from the steel as a component of the slag. Silicomanganese generally contains 65 to 68 percent manganese and about 17 percent silicon
Silico-manganese (Si-Mn) is a metallic ferro alloy which is being used to add both silicon (Si) and manganese (Mn) as ladle addition during steelmaking. Because of its lower carbon (C) content, it is a preferred ladle addition material during making of low carbon steels.
Si-Mn is a ferroalloy composed principally of Mn, Si, and Fe (iron), and normally contains much smaller proportions of minor elements, such as C, phosphorus (P), and sulphur (S). The ferroalloy is also sometimes referred to as ferro-silicon-manganese.
Both Mn and Si play an important role in the manufacturing of steel as deoxidizing, desulphurizing, and alloying agents. Si is the primary and more powerful deoxidizer. Mn is a milder deoxidizer than Si but enhances the effectiveness of the latter due to the formation of stable manganese silicates and aluminates. It also serves as desulphurizer. Mn is used as an alloying element in almost all types of steel. Of particular interest is its modifying effect on the iron-carbon (Fe-C) system by increasing the hardenability of the steel.
There are two families of Mn alloys one is called Si-Mn while the other is known as ferro-manganese (Fe-Mn). Si-Mn adds additional silicon in liquid steel which is a stronger deoxidizer and which also helps to improve some mechanical properties of steel. In each family, content of C can be controlled and lowered when producing low C grades. Around 93% of all the Mn produced is in the form of Mn ferroalloys consists of the Fe-Mn grades and the Si-Mn grades.
The Fe-Mn grades are high carbon (HC), medium carbon (MC), low-carbon (LC) and very low carbon (VLC), whereas the Si-Mn grades include medium carbon (MC) and low carbon (LC). The steel industry is the only consumer of these alloys. However as the average consumption of Mn in one ton of steel is around 7 Kg, the requirement of these two ferro alloys amounts to considerable tonnages.
To cover the need for Mn and Si, the steelmaker has the choice of a blend of Si-Mn, HC Fe-Mn and Fe-Si governed of by specifications on C, Si, and Mn. Normally earlier a mixture of HC Fe-Mn and Fe-Si was used, but now a trend towards more use of Si-Mn is seen at the expense of the two others. This is primarily for economic reasons.
