The presence of silicon in silicon aluminum alloy can improve the fluidity of the alloy, reduce the tendency of hot cracking, reduce porosity, and improve air tightness. This type of alloy has good corrosion resistance and medium machining performance, has medium strength and hardness, and has low plasticity. It is used to manufacture low and medium strength castings with complex shapes, such as cover plates, motor housings, and brackets. And so on, also used as brazing solder.
Silicon-copper alloys are used to refine grains and improve electrical conductivity.
Ferrosilicon alloy is an iron alloy composed of silicon and iron. Ferrosilicon is a ferrosilicon alloy made of coke, steel scraps, and quartz (or silica) smelted in an electric furnace. Because silicon and oxygen are easily synthesized into silicon dioxide, ferrosilicon is often used as a deoxidizer during steelmaking. At the same time, since SiO2 emits a lot of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. Used as inoculant and spheroidizing agent in the cast iron industry. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of nodular cast iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent . At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry. 75# Ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pidgeon method of magnesium smelting. The magnesium in CaO.MgO is replaced. Each ton of metal magnesium will consume about 1.2 tons of ferrosilicon. Production plays a big role. In addition, the ground or atomized ferrosilicon powder can be used as the suspended phase in the mineral processing industry. It can be used as coating for welding rod in welding rod manufacturing. High-silicon ferrosilicon can be used to make silicone and other products in the chemical industry. Among the above applications, the steelmaking industry, foundry industry and ferroalloy industry are the largest users of ferrosilicon. They consume more than 90% of ferrosilicon. Among the various grades of ferrosilicon, the most widely used is 75% ferrosilicon. In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed per ton of steel produced.
Silico-manganese alloy Silico-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is an iron alloy with a wide range of uses and a large output. Manganese-silicon alloy is a commonly used composite deoxidizer for steelmaking, and it is also a reducing agent for the production of low-carbon ferromanganese and electro-silicothermal production of metallic manganese. Manganese and silicon are the main alloying elements used in carbon steel. Manganese is one of the most important deoxidizers in the steelmaking process. Almost all steel grades require manganese to deoxidize. Because the melting point of the oxygen product generated when manganese is used for deoxidation is low, it is easy to float; manganese can also increase the deoxidation effect of strong deoxidizers such as silicon and aluminum. All industrial steels need to add a small amount of manganese as a desulfurizing agent, so that the steel can be hot rolled, forged and other processes without breaking. Manganese is also the most important alloying element in various steel grades, and 15% is also added to alloy steel The above manganese can increase the structural strength of steel. Silicon is the most important alloying element in pig iron and carbon steel after manganese. In steel production, silicon is mainly used as a deoxidizer for molten metal, or as an alloy additive to increase steel strength and improve its performance. Silicon is also an effective stone grinding medium, which can turn the carbon in cast iron into free stone grinding carbon. The silicon added to standard gray cast iron and ductile iron can reach 4%. A large amount of manganese and silicon are added to the molten steel in the form of iron alloys: ferromanganese, silicomanganese and ferrosilicon.
