Ferromanganese is divided into three categories according to its carbon content: low carbon category: carbon is no more than {{0}}.7%; medium carbon category: carbon is no more than 0.7% to 2.0%; high carbon category: carbon is no more than 2.0% to 8.0%.
The proizvod metoda of high carbon ferromanganese has blast peć metoda metoda i električna peć proizvodnja, the following are uvedeno the karakteristike of these two methods:
Blast Peć Metoda: Manganse ore, koks i lime are dodano into the Blast Peć for taljenje to get the Blast Peć Ferromanganese With Manganse content of 52%~76%%%/phosphorus content of 0.4%~0.6. As the only difference between blast furnace and electric furnace for smelting high carbon ferromanganese is the toplinski source, so the structure, geometrija and operation method of the two peći are different, the the principle of smelting high carbon ferromanganese in the two peći is the same.
Međutim, the two peći use the the same kind of mangan ore talje to make the the dobiven proizvod fosfor content is not the same, the higher the blast peć proizvod is than the electric peć proizvod {{{{{0}.07%~0.11%. This is due to the the blast furnace smelting charge kompozicija of the coke ration for the electric peć taljenje 5 ~ 6 with, so there are more coke fosfor into the legura, the the Blast Furnace Smelting Furnace Temperature Is Lower, THUS The Volatilization of fosfor In The Process of Smelting THAN The Electric OL Is Lower Than The Volatilization Amount of About 10%.
Tu su tri metode za taljenje visoko ugljik ferromangane by električna peć metoda, naime, solvent metoda, otapala metoda, otapala metoda i otapalo manje metoda. The following is a description of the method commonly used for smelting high-carbon ferromangane: solvent metoda.
Otapalo metoda. Solvent metoda je a a uobičajeno usvojena metoda for taljenje visoko ugljik ferromangan. In dodatak to mangan ore, koks in the composition the charge, there are lime, smelting with high alkality slag operation alkalnost, B=1.3 ~ 1.4, the use of sufficient reductant, has been to minimize the manganse content in the slag, improve the recovery rate of mangan. Ova metoda koristi se to talina visoko ugljik ferromangane s sirom i bogatom manganom rudom.
