High carbon ferromanganes


 High carbon ferromanganese

High carbon ferromanganese is an iron alloy with iron and manganese as the main components. It is used as deoxidizer, desulfurizer and alloying agent in steel work.
This product is not only suitable for low-carbon alloy structural steel, but especially for high-quality steel. Without changing the original steel-making process technology, it can optimize the alloy, improve the inherent quality of steel, and reduce the cost of steel-making alloys. It has obvious advantages. economic benefits.
The appearance of high carbon ferromanganese has a bright metallic luster without powder and slag inclusions.
In addition to manganese and iron, the components also contain impurities from silicon, carbon, sulfur and manganese ore.
According to the different carbon content, it can be divided into high carbon ferromanganese (carbon content ≤7.5%-2%), medium carbon ferromanganese (carbon content ≤2%-0.5%)
And low-carbon ferromanganese (carbon content ≤ 0.5%), and nitrogen-containing ferromanganese.
There are two types of reduction smelting of high carbon ferromanganese: flux method (also known as low manganese slag method) and flux-free method (high manganese slag method). The principle of the flux method is the same as that of blast furnace smelting, except that electric energy is used instead of coke for heating. By adding lime to form high basicity slag (CaO/SiO2 is 1.3-1.6) to reduce the loss of manganese. The flux-free smelting method does not add lime, resulting in a low-iron, low-phosphorus, and manganese-rich slag with low alkalinity (CaO/SiO2 less than 1.0) and high manganese content.
Manganese in high carbon ferromanganese can also be used as alloy, and also used in free cutting steel, alloy structural steel, spring steel, bearing steel, tool steel, etc. Among them, wear-resistant high manganese steel can also be widely used in the manufacture of excavators and crushing equipment.
