Abstract

Procedeu de obtinere a amestecurilor de carburi complexe dure, prin eventuala încalzire la 1500 degree C a deseurilor de carburi dure sinterizate, pentru desprinderea de pe suporturi metalice, urmata de tratarea termica în curent de hidrogen a deseurilor astfel pregatite, de sfarîmare groba, de macinare fina, de corectare a compozitiei si de amestecare cu amestec proaspat pentru obtinerea compozitiei prestabilite.Process for obtaining hard complex carbide blends by eventually heating at 1500 degrees C of sintered hard carbide waste to remove it from metallic supports followed by thermal treatment in the hydrogen stream of the thus prepared waste streams of grinding grinding fine, compositional correction and blending with fresh mixture to obtain the preset composition.
