First of all, from the chemical composition, 65 high-carbon ferro manganese is mainly composed of iron, manganese and carbon three elements. Among them, iron is the main component, manganese is the key component, and the content of carbon is relatively low, but it has an important effect on the properties of the alloy.
Secondly, the physical properties of 65 high-carbon ferro manganese mainly include its density, melting point, hardness and so on. These properties are closely related to the composition and structure of the alloy. For example, the density of 65 high-carbon ferro manganese is usually between 7.8-7.85g/cm³, the melting point is between 1200-1300℃, and the hardness is high.
In addition, 65 high carbon ferro manganese also has good wear resistance, corrosion resistance and high temperature strength and other properties. These properties make it widely used in metallurgy, machine building and other industrial fields.
65 High carbon ferro manganese application range
Steel smelting: In the process of steel smelting, 65 high-carbon ferro manganese is used as an alloying element additive, which can significantly improve the strength, wear resistance and corrosion resistance of steel. At the same time, it is also an important raw material for the production of special steel.
Casting: In the casting process, 65 high-carbon ferro manganese is used as inoculant and modifier, which can effectively improve the density and mechanical properties of the casting and extend the service life of the equipment.
Mechanical manufacturing: In the field of mechanical manufacturing, 65 high-carbon ferro manganese is used to manufacture various parts and structural parts, such as gears, bushings, bearings, etc. Its excellent wear resistance and corrosion resistance can effectively improve the working efficiency of the equipment and extend its service life
65 High carbon ferro manganese production method
There are two main types of flux method and non-flux method.
The flux method uses alkaline slag operation, in addition to manganese ore and coke, the charge is also equipped with a certain flux (lime) and enough reducing agent. High basicity slag is used for operation, and the basicity of slag (CaO/SiO2) is controlled at 1.3-1. In order to reduce the manganese content in slag as much as possible and improve the recovery rate of manganese.
The fluxless method uses acid slag operation, the charge does not add lime, and smelting under the condition of insufficient reducing agent. Through this method, ferro manganese can be obtained, and low phosphorus rich manganese slag containing about 30% manganese can be obtained for the production of manganese silicon alloy and low carbon ferro manganese for the production of manganese silicon alloy. The advantages of flux-free smelting are low energy consumption and high comprehensive recovery of manganese. The disadvantage is that due to the operation of acid slag, the corrosion of carbon lining in the smelting process is serious, and the lining life is short.
