Position-adjustable gas atomization pulverizing system

Abstract

The invention discloses a position-adjustable gas atomization pulverizing system, and relates to the technical field of soft magnetic alloy metallurgy. The problems that a common existing cooling tankand a metal atomization device are generally arranged in a fixed manner, the cooling speed of an amorphous or nanocrystalline alloy is difficult to control due to a fixed structure, the amorphous cooling value cannot be reached, amorphization cannot be achieved, only nucleation crystallization can be achieved finally, and the machining efficiency cannot be conveniently improved are solved. According to the key points of the technical scheme, a moving mechanism and a swinging mechanism are included, an air injection device is arranged at the movable end of the moving mechanism, a liquid outletdevice is arranged on the air injection device in a penetrating manner, and a heating device is connected to the liquid outlet device; and a rotating tank is arranged at the movable end of the swinging mechanism and located below the liquid outlet device, and the purposes that the air injection device and the liquid outlet device move in real time so that the high-pressure solution flow can be perpendicularly matched with the end face of the surface side of a cooling liquid film, the cooling speed of the amorphous or nanocrystalline alloy can be controlled conveniently, and the machining efficiency can be improved conveniently are achieved.

Description

technical field [0001] The invention relates to the technical field of soft magnetic alloy metallurgy, in particular to a position-adjustable gas atomization pulverization system. 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. Gas 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 gas atomization equipment, which realizes the conversion between the kinetic...

AI Technical Summary

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 or nanocrystalline alloys, and thus cannot reach the cooling value of amorphization, that is, it cannot reach Until the realization of amorphization, it can only nucleate and crystallize in the end, which is not convenient for improving processing efficiency
