Product Introduction
Medium carbon ferromanganese (MCFM) is a type of ferrous alloy containing manganese and iron in combination with carbon. It is widely used for the production of electrodes, especially E6013 electrodes in the steel industry. In addition to its use in the steel industry, MCFM is also used in other industries such as the foundry industry.
MCFM can be produced by various processes, including refining high-C Fe-Mn (high-C MCFM) or by the silicothermic method, which uses silicon in the Si-Mn alloy to reduce additional MnO added as ore or slag. MCFM can also be produced by the carbon-carbon reduction process, in which carbon is added to iron or other ferromagnetic materials to produce a ferromagnetic material.
The carbon content of MCFM can range from 1% to 1.5%, with a carbon content of 1% to 1.5% being the most common. The manganese content can range from 75% to 85%, with Mn content ranging from 75% to 85%. The carbon and manganese content of MCFM can affect its properties, making it suitable for various applications.
In the steel industry, MCFM is used as a deoxidizer and alloying additive. MCFM with high Fe-Mn content or MCFM with high C content, which is produced during refining of Fe-Mn with high C content, can be used in smelting process to produce MCFM electrodes. The ratio of manganese to Fe-Mn is generally greater than 7, and the ratio of phosphorus to manganese is less than 0.003.
To produce MCFM electrodes, the Fe-Mn ore must be roasted to remove the carbon, and then the ore powder must be sintered and agglomerated. Ores with high iron and phosphorus content can only be used in combination or by selective reduction to obtain manganese-rich slag with low iron and phosphorus content. In smelting, coke is used as a reducing agent, and some mills also use lean coal or anthracite as auxiliary raw materials. Lime is usually added as an auxiliary raw material during the smelting process, as it can help adjust the pH and remove impurities from the slag.
In addition to its use in the steel industry, MCFM is also used in other industries such as the foundry industry. MCFM can be used as a deoxidizer and alloying additive in the casting process, which can improve casting properties such as durability, machinability and formability.
