Description
technical field [0001] The invention relates to the technical field of alloy powder preparation, in particular to a vacuum air atomization powder making bucket. Background technique [0002] Gas atomization powder production is a powder preparation method in which a fast-moving fluid (atomization medium) impacts or otherwise breaks a metal or alloy liquid into fine droplets, and then condenses into a solid powder. The atomization method is the best way to produce fully alloyed powder, and its product is called pre-alloyed powder. Each particle of this powder not only has the same uniform chemical composition as the given molten alloy, but also refines the crystal structure due to rapid solidification; eliminating the macro-segregation of the second phase. [0003] The atomization pulverization method is divided into two categories: "double-flow method" (breaking the alloy liquid flow with the atomization medium flow) and "single-flow method" (breaking the alloy liquid flow ...
