Abstract

Because of the increasing application of RE and the need for the injection metallurgy, we have been trying to find out a suitable powder-making technique of RE-Si ferroalloy widely used as additive in steel and spheroidal cast iron. In this paper, the high-speed photographic technology has been used to analyse the different atomizing methods of RE-Si ferroalloy, especially the atomizing method with gas-jetting and quenching method in water. During atomizing, not only has the process of breaking a single molten alloy droplet been photographed, but also the moving track and changing speed of different sizes of particles have been photographed, and then analysed and calculated. Here we have also put forward our opinion of the mechanism of the quenching process in water of RE-Si ferroalloy, providing a theoretical basis for reliable atomizing technique.
