发明名称 Method and device for the production of ceramic-free metal powders
摘要 The invention relates to a method and a device for the production of ceramic-free metal powders, preferably from metals with melting points above 1000 DEG C, from the melt. The melt is fed in the form of a stream from a melt container with a gravity outlet to a divider and is divided. To achieve the object of providing constant operating parameters for the cross-section and position of the stream and of producing metal powders with a constantly reproducible particle size range, the invention proposes the following measures: Between the outlet (18) and the divider (19), the stream (26) is concentrated and centred relative to the divider (19) by means of a pouring funnel (6) which is not brittle at the melt temperature. It is particularly advantageous if the pouring funnel comprises a hollow body (21) which is dimensionally stable in relation to the melt and has a complementary insert (25) of fused or vitreous silica. <IMAGE>
