Silicon-manganese alloys are mainly divided into the following two types according to different compositions and uses:
Depending on the composition and use, there are many different grades of silicon manganese alloy.
The common silicon manganese alloy grades are FeMn68Si18, FeMn65Si17, FeMn60Si14, etc. In these grades of silicon manganese alloy, the manganese content is high, the silicon content is low, and the use is wide.
In addition, there are low-carbon silicon manganese alloys, such as FeMn60Si14C0.3, etc., this alloy has a low carbon content, mainly used for the production of low carbon steel, stainless steel, heat-resistant steel and so on.
FeMn68Si18 silicon manganese alloy is a kind of iron alloy with wide application and large yield. Its main uses are as follows:
1.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.
2.FeMn68Si18 silicon manganese alloy can also be used for the production of medium and low carbon ferromanganese and electrosilicothermal metal manganese semi-finished products. It is the main raw material for the production of medium and low carbon ferromanganese, and the consumption accounts for the second place in the ferroalloy products of electric furnace.
3.FeMn68Si18 silicon manganese alloy with carbon content below 1.9% can be used to produce metal manganese and ferro manganese alloys.
6517 Silicon manganese alloy is a versatile iron alloy, which is mainly composed of manganese, silicon, iron, and some carbon and other elements. Its main uses can be divided into the following:
In the process of steelmaking, 6517 silicon manganese alloy is commonly used as a composite deoxidizer, but also as a reducing agent for the production of low carbon ferromangane and the production of metal manganese by electrosilicothermal method. It can effectively remove oxygen in steel and improve the purity and quality of steel. In addition, it can also be added to various types of steel to improve the structural strength and wear resistance of steel.
In the chemical industry, 6517 silicon manganese alloy can be used to manufacture chemical equipment, pipelines, valves, etc., with strong corrosion resistance. This is because it contains a certain amount of silicon and manganese in its composition, which can form a stable oxide when used in combination with other metal elements and improve the corrosion resistance of the material.
In the aerospace field, 6517 silicon manganese alloy can be used to manufacture aircraft parts, rocket engine casings, etc., requiring high strength and fatigue resistance. This is because 6517 silicon manganese alloy has good mechanical properties, can maintain high strength and stability at high temperatures.
In the power industry, 6517 silicon manganese alloy can be used to manufacture parts for generator sets, transformers and other equipment, requiring good electrical conductivity and high temperature resistance. This is because its composition contains silicon and manganese, two elements that can maintain good electrical properties and stability at high temperatures.
Silicon manganese alloy 6014 is mainly used as a deoxidizer and alloy additive in steelmaking, which can reduce the content of aluminum and nitrogen in steel, and at the same time can produce a reducing agent of low-carbon ferromangan-manganese and electrosilicothermal metal manganese.
In the smelting of ordinary steel, silicon is usually used as a deoxidizer, but because silicon can maintain a high content in steel, can reduce the plasticity and toughness of steel, so the deoxidizer is only suitable for smelting ordinary steel, not suitable for smelting low silicon low carbon steel. In contrast, silicon manganese alloy 6014 is more practical as an ideal deoxidizer. It can not only reduce the content of aluminum and nitrogen in steel to a lower level, but also because of its high affinity with oxygen, oxygen can be quickly converted into low melting point, easy to float deoxyte particles, thus avoiding the generation of a large amount of aluminum oxide.
In addition, the use of silicon manganese alloy 6014 can also avoid the use of aluminum manganese titanium, aluminum manganese calcium, aluminum wire and low-carbon ferromanganese and other higher cost alloy materials.
