Ferrosilicon manganese alloy characteristics：
Main components: Manganese, silicon, iron, a small amount of carbon and other elements. Common grades include FeMn68Si18, FeMn65Si17, FeMn60Si14, etc. The manganese and silicon contents of different grades vary.
Strong deoxidation ability: Silicon and manganese have a high affinity with oxygen. When silicon manganese alloy is used in steelmaking, the deoxidation products MnSiO3 and MnSiO4 have melting points of 1270℃ and 1327℃ respectively, which have the advantages of low melting point, large particles, easy floating, and good deoxidation effect. Compared with the use of manganese or silicon alone for deoxidation under the same conditions, the burnout rate of silicon-manganese alloy is lower.
Ferrosilico manganese uses：
Wide application: Silico manganese is a ferroalloy with a wide range of uses and a large output. Its consumption ranks second among electric furnace ferroalloy products. It is an indispensable composite deoxidizer and alloy additive in the steel industry. It can be used to remove oxygen from steel, improve the quality and performance of steel, and improve the strength, hardness and wear resistance of steel. It can also be used as a reducing agent for the production of low-carbon alloys and the production of metallic manganese by the electric silicon thermal method. In the cast iron industry, it can also be used as an inoculant and spheroidizer.
Synergistic effect with other alloys: Manganese can form silicides with silicon, such as MnSiO, MnSiO3 and Mn2SiO4. the most stable silicide is MnSi. Since the negative value of the free energy of manganese silicide formation is much greater than the negative value of the free energy of manganese carbide production, the higher the silicon content in the silicon-manganese alloy, the lower the carbon content.
Silicon manganese market situation and price in early September：
Market situation: In terms of supply, although the raw materials of silicon manganese are on a downward trend, the production cost is still high, and the production of silicon manganese plants continues to be inverted. Some large plants have recently suspended production. Most silicon manganese plants have closed their orders and are waiting for the mainstream steel bidding prices. In terms of demand, the purchasing enthusiasm of downstream steel mills is weak, and the first round of inquiries from the mainstream steel bidding did not meet expectations. Overall, the silicon manganese market continues to be sluggish.
Price: On August 29, the price of silicon manganese 6517 in the northern market was 6100-6300 yuan/ton, a decrease of 50 yuan/ton from the previous Wednesday; the price of silicon manganese 6517 (cash) in the southern market was 6200-6400 yuan/ton, a decrease of 50 yuan/ton from the previous Wednesday.
