1. Introduction
RF plasma has the good features of high energy density, high heating intensity, plasma arc of large volume, simple process, etc. Also because it is electrodeless there is no pollution on product caused by electrode evaporation.
Principle: inert gas (argon) is ionized to be stable plasma torch of high temperature argon under the effect of high frequency power supply; raw materials of powder are introduced into plasma torch by carrier gas (nitrogen) through powder feeder, powder particles absorb much heat when in plasma torch of high temperature and their surfaces melt rapidly; powders are introduced into reactor at a tremendous rate and then they are cooled fastly under inert gas and solidified into spherical powder under the effect of surface tension; and powders are collected in the collector.
2. Features
1. High heating temperature, fast cooling speed, and no electrode pollution;
2. Reacting materials being distributed dynamically in plasma, avoiding agglomeration and growth of powder, suitable for melting and spheroidizing;
3. Manufacturing powder of high melting metal and oxide, such as Mo, Ti, W, WC, aluminium oxide, silicon oxide, zirconium oxide, etc;
4. Regular powder shape with spheroidization rate of over 90%; smooth and bright surface; good flowability; and increasing powder compactness and bulk density.
3. Technical Parameters
1. Total power: 100kW;
2. RF torch: 100kW, 3MHz;
3. Capacity: 3-4kg/h;
4. Ultimate vacuum degree: 8*10-2Pa;
5. Total power of the whole equipment: 150kW.
4. Equipment Structures
RF plasma spheroidization powder manufacturing equipment is mainly consisted of the following parts:
