抄録

The production process for spherical particles by flame spraying is a method for exposing solid particles to the combustion flame and to fuse them to make spheres. It is used for producing ceramic or metal spherical particles. In the development of this process it is very important to analyze the fusing and sphering phenomena of solid particles quantitatively. In this study a model of momentum and heat transfer in the process was formulated to analyze these phenomena. The velocity distribution of the particles, the temperature distributions in the particle, and the melting state were calculated by this model. Spherical particles of alumina and silica were produced in experiments using the flame spray method. These experimental results were approximately in accordance with the calculated ones. From these results, the model was found to be very useful for process analysis of the production of spherical particles from solid powder by the flame spray process.
