Silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements, which is a kind of iron alloy with wide use and large yield. The chemical composition of silicon-manganese alloy is mainly silicon and manganese, the content of silicon is generally between 10% and 35%, and the content of manganese is generally between 60% and 85%. In addition, there are some other impurities in silicon manganese alloy, such as calcium, magnesium, aluminum, titanium and so on.
Silicon manganese alloy pellet binder is white solid powder, made of organic and a variety of chemical raw materials through chemical reaction and physical processing. Non-corrosive, does not contain sulfur, phosphorus and other harmful elements, for manganese ore powder manganese dust and other powder molding, 1 ton can produce 40-50 tons of pellets, product yield of 95%, wet ball more than 2 meters high fall does not disperse, no sintering natural curing or drying, high strength, does not reduce grade. Replacing some manganese ore blocks into the furnace, it has the characteristics of stable furnace condition, fast feeding, good air permeability, no slag turning, no fire, normal gas recovery, etc. The silicon manganese alloy ball used in smelting has the characteristics of stable furnace condition, good permeability of the charge, improving product quality, eliminating the hidden danger of blast furnace, energy saving and emission reduction, and clean production.
First, the use of silicon manganese alloy
Silicon manganese alloy has many uses in steel production, the most important of which is used as a steel deoxidizer. The silicon in the silicon manganese alloy can be combined with the oxygen in the steel to form a solid deoxidizing compound, which can prevent the harm caused by oxygen to the steel and improve the quality of the steel. Another important use of silicon manganese alloy is as an alloy additive, which can improve the properties and strength of steel and extend the service life of steel. In addition, silicon manganese alloy can also be used as heap collapse materials, casting AIDS and so on. At the same time, in the casting industry, silicon manganese alloy can also be used as an alloy additive in casting to improve the quality and hardness of castings.
Second, the properties of silicon manganese alloy
Silicon manganese alloy has good oxidation resistance and high temperature stability. It can effectively reduce the oxidation reaction of steel when it comes into contact with gases and liquids at high temperatures, thereby improving the stability and durability of steel. At the same time, silicon manganese alloy also has good thermal conductivity and electrical conductivity, which can effectively improve the electrical and thermal conductivity of steel, so that the processing efficiency of steel is higher.
Third, the manufacturing process of silicon manganese alloy
The manufacturing process of silicon manganese alloy mainly includes raw material selection, melting, casting and processing. First, select high-purity silicon, manganese and iron and other raw materials, and then these raw materials are mixed evenly according to a certain proportion, and put into the furnace for smelting. In the smelting process, the content of silicon and manganese in the alloy needs to be controlled to ensure that the properties of the alloy meet the requirements of the standard. Finally, the smelted alloy is cast and formed, and processing measures are carried out to meet the needs of various industrial fields.
Through the analysis of the uses, properties and manufacturing processes of silicon manganese alloy, we can find that silicon manganese alloy is a very important alloy material in metallurgy and casting industry. It can not only improve the quality and performance of steel and castings, but also has good high temperature stability and electrical conductivity, and has a wide range of applications.
