Information

In recent years, with the continuous development of 3D printing technology, the field of powder metallurgy has attracted more and more attention. Metal chromium is often used in metallurgy, chemical industry, electroplating, pharmaceutical and other industries due to its good chemical stability, high temperature resistance and corrosion resistance. At present, the chromium powder produced by the conventional powder-making technology is generally irregular in shape, resulting in the disadvantages of poor fluidity of the chromium powder and low density of the powder product. In order to improve the fluidity of the powder, a spherical chromium powder was prepared.

Wholesale Spherical chromium powder

At present, there are radio frequency plasma methods for producing spherical chromium powder at home and abroad. Radio frequency plasma has the advantages of high energy density, high heating intensity, large volume of plasma torch, and simple process for processing materials. Irregular chromium powder particles of raw materials are sprayed into the plasma torch by carrying gas through the feeding gun, and are rapidly heated and melted to form highly spherical droplets, which are rapidly solidified in a very short period of time to form spherical chromium powder. However, the chromium powder prepared by the plasma method has good sphericity, but the gas content is difficult to control. The cost of this method is high, and it is impossible to prepare fine powder with a particle size of less than 45 μm due to the limitation of the feeding method.
