Problems solved by technology
[0003] Existing cooling tanks and metal atomization devices are generally fixed arrangements, and the fixed structure will make it difficult to control the cooling rate of amorphous alloys, and then the cooling value of amorphous alloys cannot be achieved, that is, the realization of amorphous alloys cannot be achieved. Crystallization, in the end it can only nucleate and crystallize, which is not easy to improve processing efficiency

The water-air combined atomization powder milling process provided by the invention makes the rotary tank swing and rotate, so that the cooling liquid in the tank forms a cooling liquid film attached to the inner side wall of the tank; the air jet device and the hot-melting device cooperate to output a The powder flow is sprayed to the surface side end surface of the cooling liquid film; the air jet device and the hot-melting device move in real time to make the powder flow and the surface side end surface of the cooling liquid film form a vertical fit. Based on the application of the water-air combined atomization and pulverizing process, the air-jet device and the hot-melt device are used for real-time movement to make the powder flow form a vertical fit with the surface side end face of the cooling liquid film, so as to facilitate the Control the cooling rate of amorphous or nanocrystalline alloys to achieve the amorphization cooling value in order to improve processing efficiency.
Description
technical field [0001] The invention relates to the technical field of soft magnetic alloy metallurgy, in particular to a water-gas combined atomization powder-making process and a water-gas combined atomization powder-making device using the same. Background technique [0002] Atomization pulverization is an important method for producing metal powder. The process of solidifying into powder on subsequent flights. Due to its high efficiency in preparing metal powder and controllability of particle size, it has received continuous attention in the field of powder metallurgy. The atomization equipment greatly affects the properties of the prepared metal powder, and the atomization nozzle is the key component of the entire atomization equipment, which realizes the conversion between the kinetic energy of the air and the surface energy of the metal powder. [0003] The existing cooling tanks and metal atomization devices are generally fixed in arrangement, and the fixed struct...
