Abstract
Inventia se refera la un procedeu de obtinere a pulberilor din metan si aliaje neferoase, cu temperatura de turnare sub 850 degree C prin autoamtizare, efectuînd absorbtia topiturii si pulverizarea subsecventa cu aer comprimat într-o incinta de sedimentare, caracterizata prin aceea ca, în scopul obtinerii unor pulberi sferice calitativ superioare, cu omogenitate grunolometrica constanta, se efectueaza absorbtia topiturii metalice din cuptorul de topire într-un pulverizator de tip uzual, cu aer comprimat la 6 at si pulverizarea urmata de clasarea subsecventa a pulberii cu aer fals absorbit în capatul incintei de sedimentare din zona de pulverizare, direct în buncarele plasate la partea inferioara a acesteia, mentinîndu-se constant raportul între presiunea aerului si debitul de metal pulverizat.The invention relates to a process for obtaining powders from methane and non-ferrous alloys with a casting temperature below 850 ° C by self-priming, effecting the melt absorption and subsequent spraying with compressed air into a sedimentation chamber, characterized in that, in order to obtaining a higher quality spherical powder with constant grunnometric homogeneity, absorbing the metal melt from the melting furnace in a usual type 6-liter atomizer and spraying followed by the subsequent classification of the powder with falsely absorbed air at the end of the enclosure of sedimentation from the spray zone directly into the bunkers placed at the bottom thereof, maintaining constant the ratio of the air pressure to the pulverized metal flow.
