High-carbon ferromanganese is used in steel making and engineering industries as deoxidizer and alloying addition. Ferromanganese of JSC KGIW production is notable for stable chemical composition and low content of harmful impurities phosphorus, silicon, sulfur, which allows to use it for manufacturing of special types of steel.
2020-5-2Ferromanganese PSK-78, State Standard 4755-91 Ferromanganese is an alloy in which there are basic components are manganese and iron. The addition of manganese increases the hardness of steel, its corrosion resistance and resistance to tearing.
After reaching the desired carbon content in the molten ferromanganese ferromanganese and ore-lime mixture jointly publish in the bucket and then poured into moulds. The cooled end of the ore-lime melt crushed and used as a component of the charge in the smelting of high-carbon ferromanganese.
2014-8-4Materials Preparation The industrial high-carbon ferromanganese slag was obtained crushed with a size fraction of 10 to 18 mm from Eramet Norway Sauda, Norway. The proximate analysis of the slag obtained is presented in Table I. For homogeneity, ...
2019-12-16Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc

Hydrogenetic ferromanganese crusts hereafter referred to as crusts on Pacific seamounts are formed by the precipitation of ironmanganese oxides from seawater on volcanic and biogenic substrate rocks. As crusts grow continuously and have very slow growth rates of between 1 and 10 mmm.y., they can potentially be used as records of the Neogene paleoceanographic and paleoclimatic ...
2013-12-24nese ferroalloys such as ferromanganese or silicomanga- nese alloys 1. The rapid expansion in the world and Egyptian steel industry in recent years and consequently the increasing demand on the essential ferromanganese necessitated the domestic production of this ferroalloy. Egyptian Manganese ores are located in Egypt in two

2014-5-22The ferromanganese industry is under pressure to deal with the slag arising from the production of ferromanganese, which is discarded in landfills or slag heaps. This material poses an environmental and health risk to surrounding ecosystems and communities, and disposal costs are increasing. Ferromanganese slag contains an appreciable amount of

2011-3-3the most important objectives during ferromanganese production. Raw material properties play a very important role in determining the whole process1. Knowledge about material properties, such as chemical composition, MnFe ratio, reactivity, and mechanical strength of raw materials, is essential to having good control of the ferromanganese furnace.
2014-6-19This work aims at studying the reactivity of Egyptian manganese ores to be used in the production of ferromanganese alloys in submerged electric arc furnace. Ores with different manganese content high-medium and low were selected and characterized by X-Ray Fluorescence XRF, X-Ray Diffraction XRD and Scanning Electron Microscope SEM. The main mineralogical compositions in
form of high carbon ferromanganese. Ferromanganese lumps of 1080mm are preferred in the steel making process to optimize the manganese recovery, deoxidation and losses during handling. Ferromanganese is made by carbothermic reduction of manganese ores in the electric arc furnace. Liquid hot metal is casted and crushed into 1080mm size.

Fe-Mn is a solid lumpy material practically odorless when dry and usually with a silvery metallic surface. The surface becomes generally covered with a dark layer of oxides during storage. It is generally free from extraneous contaminations such as slag and non-metallic inclusions etc. It is normally supplied as crushed and screened material.

The DC furnace is ideally suited for efficient reduction of both high and low-grade fine ores, using readily available reductants like fine coal and anthracite. Since fine raw materials can be fed directly into a DC furnace, no additional agglomeration facility is needed. Tenova Pyromet is a world leading company in the design and supply of Direct Current DC Furnaces for the production of ...
