Abstract

Many metallurgical processes in some moment needs that the specific material in form of chunks, grains, powder, dust etc. must be added. The results and benefits from it depends on the fast and uniform distribution of the introduced material inside the whole volume of the alloy being processed. That is why the method of pneumatic powder injection is widely used to introduce the powdered material of various kinds into the molten alloys. But the problem of particles penetration into the liquid metal is quite complicated and many variables and parameters influence the final result. In the paper the results of the model laboratory research on this problem were presented. The model particles of spherical shape of different dimensions, made of various materials were introduced into water. The geometrical features of the area of particle, entrapped air and water interaction was analyzed. The results were compared to those achieved by other researchers. The results can be then an initial stage to the next research to combine the obtained data with the results of real pneumatic powder injection experiments.

Keywords: cast iron, pneumatic powder injection, particle immersion, particle penetration, penetration dynamics
