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 invention provides a water-gas combined atomization powder making technology. According to the water-gas combined atomization powder making technology, a rotating tank swings and rotates, so thata cooling liquid in the tank forms a cooling liquid film attached to the inner side wall of the tank; an air injection device and a hot melting device are matched to output powder flow, so that the powder flow is injected to the end surface of the surface side of the cooling liquid film; the air injection device and the hot melting device move in real time, so that the powder flow can be perpendicularly matched with the end surface of the surface side of the cooling liquid film. The water-gas combined atomization powder making system is based on application of the water-gas combined atomization powder making technology, and the air injection device and the hot melting device move in real time, so that the powder flow can be perpendicularly matched with the end surface of the surface side of the cooling liquid film, the cooling speed of an amorphous or nanocrystalline alloy can be controlled conveniently, then the amorphous cooling value is achieved, and the machining efficiency can beimproved.
Description
technical field [0001] The invention relates to the technical field of soft magnetic alloy metallurgy, in particular to a water-gas combined atomization pulverization process and a water-gas combined atomization pulverization system using the same. Background technique [0002] Atomization pulverization is an important method of producing metal powder. Its principle is that after the high-speed airflow is accelerated by the atomization nozzle, the kinetic energy of the airflow is converted into the surface energy of small metal droplets, so that the metal flow is crushed into small droplets, and The process of solidifying into a powder on subsequent flights. Due to its high efficiency and controllable particle size for preparing metal powder, it has been continuously concerned by the field of powder metallurgy. Atomization equipment affects the performance of the prepared metal powder to a large extent, and the atomization nozzle is a key component of the entire atomization...
