45 atomized
Ferrosilicon powder is a special material that plays a crucial role in industrial production, especially in the welding field. With its unique production process, excellent product characteristics, and wide range of applications, it has become an indispensable auxiliary material in many manufacturing industries.
Production Process
1. Electric Furnace Smelting: Selected raw materials such as silica ore, coke, and steel scrap are put into an electric furnace in a specific proportion. In a high-temperature environment, coke acts as a reducing agent to reduce silicon from silica ore and fuse it with iron in steel scrap to form ferrosilicon alloy liquid.
2. Vacuum Water Atomization: The high-temperature ferrosilicon alloy liquid is rapidly broken and cooled into fine powder particles through a special device using high-pressure water atomization. This process ensures uniform particle size, spherical-like shape, and good fluidity of the product.
3. Drying and Sieving: The atomized powder contains a certain amount of moisture and needs to be dried. Subsequently, through sieving, products with different particle size specifications such as 40 mesh, 50 mesh, 60 mesh, and 100 mesh are screened out according to different industrial needs to ensure stable product quality.
Application Fields
1. Welding Material Manufacturing: As a key auxiliary material in the coating of special welding electrodes, 45 atomized ferrosilicon powder plays an important role as a deoxidizer. During welding, it can combine with oxygen in the weld to reduce the interference of oxygen on weld quality, enhance the deoxidation ability of the electrode, and thus improve the strength, toughness, and corrosion resistance of the weld. It is widely used in the welding of various metal structural parts, such as construction steel structures, bridges, machinery manufacturing, automobile manufacturing, and shipbuilding industries.
2. Flux-Cored Wire Production: Adding 45 atomized ferrosilicon powder to flux-cored wires can optimize the metallurgical properties of the wire, improve weld formation, and enhance the quality of welded joints, meeting the welding needs under different working conditions.
