Products Description
Ferrosilicon briquettes are a metallurgical material made by pressing ferrosilicon alloy powder, mainly used in steelmaking and foundry industries. They usually consist of silicon, iron and a small amount of other elements, with stable chemical properties and good metallurgical properties. Compared with traditional ferrosilicon alloys, ferrosilicon briquettes have more advantages in transportation, storage and use, so they have been widely used in modern metallurgical production.
The production of ferrosilicon briquettes mainly includes raw material processing, mixing, pressing and curing. The fine powder formed after the ferrosilicon alloy is crushed is screened to ensure uniform particle size, and then mixed with a binder to improve the molding strength. The mixed materials are pressed into briquettes under high pressure, and then naturally cured or baked at low temperature to finally form a block product with a certain strength and density. This process reduces the loss of powdered ferrosilicon during transportation and use, while improving the utilization rate of materials.
In the steelmaking process, ferrosilicon briquettes are mainly used as deoxidizers and alloy additives. Silicon combines with oxygen in molten steel to form silicon dioxide, which effectively reduces the oxygen content in steel, thereby improving the purity and mechanical properties of steel. In addition, the silicon element in ferrosilicon briquettes can improve the fluidity of steel and reduce casting defects. Compared with the direct addition of ferrosilicon alloy, the dissolution rate of ferrosilicon briquettes is more uniform, which is conducive to accurately controlling the composition of steel and reducing component segregation. In electric arc furnace steelmaking, the use of ferrosilicon briquettes can shorten the smelting time and reduce energy consumption. Due to its high density, it sinks quickly after being put into molten steel, reducing the loss in the slag and improving the recovery rate of silicon. At the same time, the block shape of ferrosilicon briquettes reduces dust pollution and improves the production environment.
In cast iron production, ferrosilicon briquettes are often used to adjust the silicon content of molten iron to improve the casting and mechanical properties of cast iron. Silicon can promote graphitization, giving cast iron better toughness and machinability. The uniform dissolution characteristics of ferrosilicon briquettes make their composition distribution in molten iron more stable, which helps to produce high-quality castings. In addition, ferrosilicon briquettes play an important role in ductile iron production. As an inoculant, it can promote graphite spheroidization and improve the strength and ductility of cast iron. Its stable chemical composition ensures the consistency of cast iron properties and reduces fluctuations in the production process.
