The invention discloses a method and device for determining the plasma arc flame length, relates to the field of powder making, and is used for solving the problem that the powder making process cannot determine and control the distance between a plasma gun and a metal bar, so that the powder quality is influenced. The method comprises the following steps: carrying out shooting on each plasma arcflame length by adopting an image acquisition system, enabling each shot original image to respectively correspond to each plasma arc flame length, carrying out shooting on the plasma arc flame lengthin initiation of powdering, respectively comparing and identifying a plurality of shot detection images with a plurality of the original images, and if it is determined that flame form of at least one detection image is same as that of at least one original image, determining the plasma arc flame length of the original image matched with the first detection image as the plasma arc flame length ofthe first detection image.
Description
technical field [0001] The invention relates to the technical field of plasma rotary electrode powder making, and more specifically relates to a method and a device for determining the length of a plasma arc flame. Background technique [0002] The working principle of the plasma rotating electrode powder making equipment is to generate large heat instantly through the high-energy plasma beam, and melt the end surface of the high-speed rotating metal bar, so that the molten metal droplets fly out at high speed under the action of centrifugal force, so as to achieve the preparation of spherical purpose of the powder. [0003] Regardless of whether it is a transferred arc or a non-transferred arc powder making equipment, the quality of the powder produced is closely related to the distance between the plasma gun and the melting end of the bar. When the current intensity and voltage are kept constant, the distance between the plasma gun and the end of the bar not only affects ...
