Product Introduction
Silicon-manganese alloy is mainly used as an intermediate material for deoxidizers and alloying agents in steel production, and is also the main raw material for the production of medium and low carbon ferromanganese.
Commonly used brands are: silicon-manganese 6517 (Mn65Si17), silicon-manganese 6818 (Mn68Si18), silicon-manganese 6014 (Mn60Si14), silicon-manganese briquette(Mn55Si15). The number after the element name indicates the percentage of the element in the alloy.

How to use silicon manganese alloy
In order to achieve the best results, you need to pay attention to the following points when using it:
1
Accurately calculate the amount of silicon-manganese alloy added according to the required chemical composition and temperature of molten steel.
2
Spread the silicon-manganese alloy evenly on the surface of the molten steel, or put it into the bottom of the molten steel.
3
Ensure the adding process is safe and rapid to avoid oxidation of silicon-manganese alloy at high temperatures.
4
Before use, make sure the surface of the silicon-manganese alloy is clean and free of attachments or impurities.
Depending on the actual situation, the addition speed, time and temperature may need to be adjusted to achieve the best results.
Uses of silicon-manganese alloy in steelmaking
Deoxidation use
It is one of the main deoxidizers in the steelmaking process. In the steelmaking process, it can combine with oxygen to produce silicon dioxide, and the generated oxygen product has a low melting point and is easy to float, so it can more effectively reduce the oxygen content in the steel.
Uses to increase toughness
It can be used in steelmaking to enable steel to be hot rolled, forged and other processes without breaking, and improve the toughness of steel. In addition, silicon-manganese alloy is also an important ferroalloy element in various types of steel. More than 15% manganese will be added to alloy steel to increase the structural strength of the steel.
Uses of graphitization
In the cast iron industry, silicon-manganese alloy is a graphitization medium that can convert carbon in cast iron into free graphite carbon. This plays an important role in improving the mechanical properties and processing properties of cast iron.
