Twin
atomizing.
Metal
flow 80-90Kg/minute (Approx.4.5t/hour).
The droplets
are propelled away from the atomizing area by the rapidly flowing
atomization gas.
The
droplet trajectories are interrupted by a substrate which serves
to collect and solidify the droplets into a coherent,almost fully dense
preform. The substrate is continually moved and lowered
relative to the atomizer as the deposition proceeds.
Large billets
can be built in this way.
Liquid
droplets or pasty particles impinge on the collector.
Solid particles
are not collected in the atomizing tower as is the case
liquid metal is atomized during the PM
process.
