Low carbon ferro manganese

Low-carbon ferro manganese is a ferro manganese product with low carbon content. Low-carbon ferro manganese is mainly used in steelmaking to improve the hardness and toughness of steel and effectively deoxidize the steelmaking process. Low-carbon ferro manganese is Many special steels are necessary raw materials for smelting, but little is known about the production method of low-carbon ferro manganese. In fact, the production method of low-carbon ferro manganese is mainly the blast furnace method, which is the most common production method for low-carbon ferro manganese. One of the methods, the production method is basically the same as casting pig iron, the principle is to extract manganese and iron from ore, but the difference is that ferro manganese steelmaking has some special rules, which are the basic system basis for the establishment of blast furnace ferro manganese production operations. The main ferro alloy raw materials for low-carbon ferro manganese production are manganese ore, coke, flux, and combustion-supporting air or oxygen-enriched. The raw materials are loaded into the furnace from the top of the furnace, and high-temperature air or oxygen-enriched air 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 molten slag and metal accumulate at the bottom of the furnace and pass through the slag port , Tapping the slag and tapping the iron at regular intervals. With the melting, reaction and discharge of the charge, and the continuous addition of new charge, the production is carried out continuously. Low-carbon ferro manganese contains a small amount of trace elements, mainly manganese and iron, which account for about 92% of the elements. The carbon content is also relatively high in ferro manganese. Generally, the carbon in low-carbon ferro manganese The content accounts for about 6%-7%. The production of high-carbon ferro chromium is mainly based on the blast furnace production method. In steelmaking, low-carbon ferro manganese ferro alloys are also widely used. Electric furnace low-carbon ferro manganese is mainly used for casting. Deoxidizer, desulfurizer and alloy additive. Low-carbon ferro manganese is mainly added during casting. Most domestic steel mills use more silicon manganese, and some high-manganese steel mills are also using it.
