PRODUCT DESCRIPTION:

Low-Carbon Ferromanganese

Low carbon ferromanganese is a low carbon content of ferromanganese products, low carbon ferromanganese is mainly used in steelmaking with enhanced steel hardness and toughness, effective deoxidation in the process of steelmaking, low carbon ferromanganese is necessary for many special steel smelting raw materials, but for low carbon ferromanganese production method is little known, in fact, low carbon ferromanganese production method is mainly based on blast furnace method is more common, The production method of low carbon ferromanganese by blast furnace is one of the more common production methods. The production method is basically the same as that of cast iron. The principle is to extract manganese and iron from ore, but the difference is that steel ferromanganese has some special rules, and these rules are the basic system basis for the establishment of blast furnace ferromanganese production operation.

The main raw materials for the production of low carbon ferromanganese alloy are manganese ore, coke and flux as well as air or oxygen rich. The raw materials from the top of the furnace into the furnace, high temperature air or oxygen rich through the tuyere into the furnace, so that coke combustion to obtain high temperature and reducing gas reduction response to the ore, melted slag, metal accumulation in the bottom of the furnace, through the slag, iron outlet time slag, iron. With the melting, reaction and discharge of the charge, and then continuously add new charge, production is continuous.

Low carbon ferromanganese contains a small number of trace elements, mainly manganese and iron elements accounted for about 92% of the elements, carbon content is also a relatively high type of ferromanganese, generally low carbon ferromanganese carbon content accounts for about 6%-7%, high carbon ferrochrome production is mainly based on blast furnace production, in steelmaking low carbon ferromanganese iron alloy application is also very wide, Electric furnace low carbon ferromanganese is mainly used for casting as deoxidizer, desulfurizer and alloy additive. Low carbon ferromanganese is mainly added when casting, most of the domestic steel mills use silicon manganese, high manganese also have some steel mills in use.

Mid-Carbon Ferromanganese

The characteristics of carbon ferromanganese is lower carbon content, carbon ferromanganese can be used in a variety of fields, but is still widely used in the field of steel, manganese is a better element used for steel, carbon ferromanganese in steel can greatly improve the hardness of steel, for the production of special steel, stainless steel and other special steel, the special treatment of carbon ferromanganese carbon can be reduced to about 0.2.

Due to the characteristics of carbon ferganese in the casting industry, in the iron and steel industry and in steel making is very widely used, it is mainly composed of manganese and iron, ferganese is widely used in steel making deoxidizer and alloy materials, it is made of manganese ore by blast furnace and electric furnace smelting, manganese density is 7.43g/cm3, melting point is 1245, C, boiling point 2150, Manganese and oxygen have a strong affinity, and can form stable manganese oxide with oxygen, in addition, as an alloy additive, ferro manganese can improve the hardness, plasticity, toughness and wear resistance of steel, widely used in structural steel, tool steel, stainless steel heat-resistant steel, wear-resistant steel and other alloy steel, manganese also has the harmful effect of desulfurization and reducing sulfur.

In the iron and steel industry, ferromanganese is an essential deoxidizer and desulfurizer in the steel making industry. Good steel needs to be deoxidized and desulfurized in the smelting process, and the use of deoxidizer will greatly increase the cost. Therefore, ferromanganese is a cheap deoxidizer. Desulfurization is the separation of sulfur and other harmful substances in steel, so that ferromanganese to achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, improve the quality of steel. In the steelmaking industry, 75% manganese is consumed in about 3-5 kilograms per ton of steel produced. According to the different carbon content, ferromanganese can be divided into three categories: medium carbon: carbon does not exceed 0.7%; Medium carbon: carbon does not exceed 0.7%~2.0%; High carbon: carbon does not exceed 2.0%~8.0%. Carbon ferromanganese can be divided into carbon ferromanganese carbon content is less than 0.7% and carbon content is 0.7%-2.0% of this product.

In the casting industry, adding carbon ferromanganese in cast iron can be used as the inoculation material and nodular material of nodular cast iron, which can prevent the formation of carbide, promote the precipitation of graphite, greatly shorten the nodular time, greatly reduce the formation of impurities in hot iron, improve the quality of cast iron, improve the performance of cast iron. In addition, the water inlet blockage of the melting furnace is reduced, and the service life of the melting furnace is extended effectively.

In steelmaking, carbon ferromanganese as deoxidation materials and alloy addition materials, is commonly used alloy, carbon ferromanganese smelting manganese ore is generally required to contain 30-40% manganese, carbon ferromanganese ratio is greater than 7, phosphorus manganese ratio is less than 0.003, before smelting should be roasted manganese carbonate ore, and then burnt into powder ore, iron, phosphorus content of high ores can only be used together, Or through selective reduction to obtain iron, phosphorus low content of manganese rich slag, coke is used as reducing agent, some plants also use lean coal or anthracite, auxiliary raw material is mainly lime, usually added in manganese silicon alloy when smelting.

High Carbon Ferromanganese

High carbon ferromanganese contains a small number of trace elements, mainly manganese and iron elements accounted for about 92% of the elements, carbon content is also a relatively high type of ferromanganese, generally high carbon ferromanganese carbon content accounts for about 6%-7%, high carbon ferrochrome production is mainly based on blast furnace production, in steelmaking, high carbon ferromanganese iron alloy application is also very wide, Electric furnace high carbon ferromanganese is mainly used for casting as deoxidizer, desulfurizer and alloy additive. High carbon ferromanganese is mainly added when casting, most of the domestic steel mills use silicon manganese, high manganese also have some steel mills in use.

High carbon ferromanganese production technology has reached the point of pure, but good ferroalloy production technology in production should also pay attention to some small problems exist, so that in the case of saving materials produced high carbon ferrochrome, production of high carbon ferromanganese, the first raw materials should be prepared fully, the use of good raw materials is very important, this is the first condition for the production of high carbon ferromanganese, In the process of smelting, the ratio of raw materials is also particularly important. Generally, the proportion of phosphorus and manganese in the normal production of high carbon ferromanganese into the furnace should be less than 0.0014.

In the production of high carbon ferromanganese slag alkalinity control is also very important, should be controlled between 0.55 and 0.60, improve the quality of silicon in high carbon ferromanganese, so that the liquid phosphorus element replaced into the slag, slag iron should be controlled below 0.9, can obtain high carbon ferromanganese.
