High Carbon Ferro Manganese
High Carbon Ferromanganese , also known as Standard ferromanganese , is one of the manganese ferroalloys smelted directly from manganese ores. Manganese content ranges from 74 to 82% and the carbon content from 7 to 7.5%. It is produced either by a blast furnace or a submerged arc furnace.
High Carbon Ferromanganese , also known as Standard ferromanganese , is one of the manganese ferroalloys smelted directly from manganese ores. Manganese content ranges from 74 to 82% and the carbon content from 7 to 7.5%. It is produced either by a blast furnace or a submerged arc furnace. The alloy is smelted either by high-manganese slag or discard slag practices. High-manganese slag practice operates with slag containing 30–42%Mn. Because of its high manganese value, the slag is recycled as feed for the production of manganese metal by electrolytic process or for the production of silicomanganese alloy. Addition of lime is avoided to keep the manganese content high. The discard slag practice operates with slag containing 10–20%Mn. This level of content is too low to extract further manganese value economically. Lime is used to keep the manganese content low in slag.
High Carbon Ferromanganese is an important manganese ore in metallurgical industry. High-quality steel is deoxidized and desulfurized in smelting. Adding a suitable amount of ferromanganese to the molten steel can reduce the harmful element, and improve the quality of the steel. In the steel industry, the consumption of ferromanganese is about 3-5kg FeMn75# to produce one-ton steel.
In the foundry industry ,High Carbon Ferromanganese as a nucleating agent and nodulizing agent for nodular cast iron. It accelerates the graphite precipitation, shortens the nodulizing time, reduces the impurity in the molt, and improves the ductility and hardness of the cast iron. In addition, ferromanganese is used in the foundry industry to increase the carbon content of the melt, which improves the hardness and wear resistance of the cast iron.
High Carbon Ferromanganese is also used as a deoxidizing agent and desulfurizing agent in the petroleum refining industry. The high-manganese slag from the refining process is recycled as a feed for the production of high-manganese steel, which is used for making turbine blades and other high-performance components.
In the manufacturing of refractories, abrasives, and other products that require high levels of hardness and wear resistance,High Carbon Ferromanganese is an idea material.The high-manganese slag from the refining process is also used as a feedstock for the production of refractories.
In summary, High Carbon Ferromanganese is widely used in the metallurgical industry. Its high manganese content makes it suitable for the production of high-quality steel, nodular cast iron, and other high-performance
