Abstract

Inventia se refera la un procedeu si la o instalatie pentru realizarea pulberilor direct dintr-o tirpitura metalica, în special a pulberilor metalice de granulatie fina, utilizate la realizarea pieselor din procedeele cunoscute de presare si sintetizare a pulberilor metalice. Procedeul consta din crearea unei presiuni în interiorul unei incinte, unde se afla o topitura metalica pentru a fi dirijata, prin intermediul unui tub, spre o camera de pulverizare. în timpul acesiunii, topitura metalica capata forma unei spume, pentru ca în camera de pulverizare sa fie transformata în niste partile fine. Instalatia este alcatuita dintr-o incinta etansa, în interiorul careia se afla creuzetul cu topitura metalica. Creuzetul este deplasabil în plan vertical pentru ca un tub sa fie introdus în topitura respectiva, tub care sa fie introdus în topitura respectiva, tub care la capatul superior este prevazut cu un ansamblu de pulverizare.
