A Brief Introduction To Low Carbon Ferromanganese

A brief introduction to low carbon ferromanganese

Low carbon ferromanganese is a ferromanganese product with low carbon content. Low carbon ferromanganese is mainly used in steelmaking to improve the hardness and toughness of steel and effectively deoxidize during the steelmaking process. Low carbon ferromanganese is Many special steels are necessary smelting raw materials, but little is known about the production method of low carbon ferromanganese. In fact, the production method of low carbon ferromanganese is mainly the blast furnace method. The production of low carbon ferromanganese by the blast furnace method is a common production method. One of the methods, the production method is basically the same as that of cast pig iron. The principle is to extract manganese and iron from the ore, but the difference is that steelmaking ferromanganese has some special rules. These rules are the basic institutional basis for establishing the blast furnace ferromanganese production operation. !

The main ferroalloy raw materials for making low-carbon ferromanganese are manganese ore, coke and flux, as well as combustion-supporting air or oxygen-rich. The raw materials are loaded into the furnace from the top of the furnace. High-temperature air or rich oxygen is blown into the furnace through the tuyere, so that the coke is burned to obtain high temperature and reducing gas to reduce the ore. The melted slag and metal accumulate at the bottom of the furnace and pass through the slag port. , The taphole discharges slag and iron regularly. As the charge is melted, reacted and discharged, and new charge is added continuously, the production is carried out continuously.

Low-carbon ferromanganese contains a small amount of trace elements, mainly manganese and iron, which account for about 92% of the elements. The carbon content is also a relatively high type of ferromanganese. Generally, the carbon content in low-carbon ferromanganese is The content accounts for about 6%-7%. The production of high-carbon ferrochrome is mainly based on the blast furnace production method. In terms of steelmaking, low-carbon ferromanganese ferroalloys are also widely used. Electric furnace low-carbon ferromanganese is mainly used for castings. Deoxidizer, desulfurizer and alloy additives. Low carbon ferromanganese is mainly added during casting. Most domestic steel plants use silicon manganese, and high manganese is also used by some steel plants.
