6818 silicon manganese alloy, mainly composed of manganese, silicon, iron, carbon and other elements. This alloy has a Si content of 18%, Mn content of 68%, and also contains small amounts of vanadium, titanium and other elements. It is a kind of ferro alloy with wide use and large yield.

 

6818 silicon manganese alloy is widely used in steelmaking, as a composite deoxidizer, it can also effectively improve the quality and performance of steel. At the same time, it is also a reducing agent for the production of low carbon ferro manganese and the production of metallic manganese by electrosilicothermal method.

Silicon manganese alloy 6818 characteristics

 

Efficient deoxidation:

6818 silicon manganese alloy has a high content of silicon and manganese, and these two elements have a strong affinity with oxygen. In the process of steelmaking, they can react with oxygen and be converted into slag deoxidation. These deoxidizes have large particles, low melting point and easy to float, so that the impurities in the liquid steel can be effectively removed.

 

Wide use:

6818 silicon manganese alloy has a wide range of applications in the iron and steel industry. It can not only be used as a deoxidizer and alloy additive in steelmaking, but also for the production of low carbon ferro manganese and the production of metallic manganese by electrosilicothermal method.

 

Excellent performance:

6818 silicon manganese alloy has high strength, corrosion resistance, oxidation resistance and good processing performance. These characteristics make it particularly suitable for the manufacture of mechanical parts that need to withstand certain loads and corrosive environments.

 

Good economy:

Compared with other alloys, the price of 6818 silicon manganese alloy is more economical. This makes it more cost-effective to use in the steel industry.

 

Easy to handle:

6818 silicon manganese alloy is easy to cut, polish and weld, which makes it more convenient in the manufacturing process.

 

 

The main uses are as follows:

 

  • In the process of steelmaking, FeMn68Si18 silicon manganese alloy is commonly used as the intermediate material of composite deoxidizer and alloying agent. Compared with manganese or silicon alone, simultaneous deoxidation with FeMn68Si18 silicon manganese alloy can reduce the burn rate from 46% and 37% to 29%, improving the quality and purity of the steel.

 

  • FeMn68Si18 silicon manganese alloy can also be used for the production of medium and low carbon ferro manganese and electrosilicothermal metal manganese semi-finished products. It is the main raw material for the production of medium and low carbon ferro manganese, and the consumption accounts for the second place in the ferro alloy products of electric furnace.

 

  • FeMn68Si18 silicon manganese alloy with carbon content below 1.9% can be used to produce metal manganese and ferro manganese alloys.
