This product is used as a reducing agent in the manufacture of low-carbon ferromanganese. Medium- and low-carbon ferromanganese. To obtain a product of low carbon and silicon content, manganese ore, lime flux, and coal are fused in a furnace, forming a melt rich in MnO. This is then contacted with silicomanganese or low-carbon …
In modern industry, manganese and its compounds are used in various fields of the national economy. Among them, the iron and steel industry is the most important field, which uses 90%-95% of manganese. It is mainly used as a deoxidizer and desulfurizer in the process of ironmaking and steelmaking, as well as for the manufacture of alloys.
As a German based manufacturer since 1947 Nabertherm offers a wide range of melting furnaces for non-ferrous metals. Energy saving insulation and high performance heating elements ensure an efficient operation of the furnace. The melting furnaces are available electrically or gas fired, in tiltable versions or bale-out design or even as combi ...
This ratio for carbon ferromanganese smelting varies from 246 to 560–750 and higher at 7.8–81 MV A furnaces for ferrosilicium smelting to 610–650 and higher at 7.5–105 MV A furnaces. In fact, the increase in the ratio of electrode current to operation voltage indicates at decrease in resistance of furnace circuit of ferroalloy electric ...
