Patent

CA 2251752

Metal powder, particularly iron/steel powder with low oxygen content, is atomized in an oxygen-free atmosphere by means of a hydrocarbon in liquid form such as paraffin, and the moist powder, still hot (60-80 °C), is transferred to a container (1) and supported therein on a screening member (2). A negative pressure is first applied below the screening member (2) so that liquid is drawn from the powder mass. An inert gas, substantially free from oxygen, is then circulated through the powder mass, whereupon vapour absorbed by the gas is condensed before the gas is recirculated to the container (1). A circulation circuit (70) for liquid atomizing medium joins the gas-circulation circuit (20) at a liquid jet pump (30).

On atomise de la poudre métallique notamment de fer ou d'acier à faible teneur en oxygène dans une atmosphère exempte d'oxygène au moyen d'un hydrocarbure sous forme liquide tel que de la paraffine, puis la poudre humide, encore chaude (60-80 DEG C) est transférée dans un récipient (1) où elle est déposée sur un filtre (2). Une dépression est tout d'abord appliquée sous le filtre (2) pour extraire le liquide de la masse pulvérulente, puis un gaz inerte, pratiquement exempt d'oxygène, circule à travers la masse pulvérulente, puis la vapeur absorbée par le gaz est condensée avant que le gaz ne soit renvoyé dans le récipient (1). Le circuit (70) de circulation du liquide d'atomisation rejoint le circuit (20) de circulation du gaz au niveau d'une pompe à jet (30).
