Problems solved by technology

[0005] There are defects in the existing method of manual cleaning of scaling, 1, cannot accurately locate and clean scaling
2. Repeated use of iron needles for many times, the needles will be partially melted in the high-temperature metal liquid (alloy liquid), and the iron content in the product will increase, which will affect the product quality
3. The passing needle directly passes through the metal liquid (alloy liquid), which may easily cause the metal liquid (alloy liquid) to splash and cause burns to the operator.
4. Long-term use of the through needle, the wear of the sub-nanometer atomizer is relatively large, resulting in an increase in production costs
5. When the operator uses the needle, because it is close to the holding furnace and the ambient temperature is high, it is prone to danger

Abstract

The invention discloses a sub-nanometer atomization system with a gas ring cutting device, which comprises: a holding furnace, a molten metal chamber, a sub-nano atomizer and a gas ring cutting device. The molten metal chamber is arranged in a holding furnace, and a sub-nano atomizer is arranged outside the holding furnace, and the molten metal chamber is connected with the sub-nano atomizer through a first conduit. The sub-nanometer atomizer is also provided with a nozzle, and a gas circumcision device is provided outside the nozzle. The system adopts the high-speed jet flow of inert gas to gas-cut and remove the scaling from the sub-nano atomizer nozzle nozzle, and can accurately locate the scaling position, with good removal effect and high efficiency, and does not need to go through the high-temperature molten metal pool , high safety, and will not pollute the molten metal pool, ensuring product quality. Moreover, the system is easy to operate, can be operated automatically, and is easy to promote, which greatly improves production efficiency and product quality.

Description

technical field [0001] The invention relates to a subnano atomization system for metal powder production, in particular to a subnano atomization system with a gas ring cutting device, belonging to the technical field of metal powder metallurgy. Background technique [0002] In the existing metal powder or alloy powder produced by the high-speed gas atomization method, during the production process, the surface of the outlet of the spray end of the sub-nanometer atomizer will slowly form a bonded metal and impurity along the flow direction of the air flow and the molten metal (alloy liquid). Fouling, commonly known as long beard. As the production time prolongs, the length of fouling along the airflow direction will increase. The length is 0-5mm and the thickness is 0-3mm. Due to the change of the atomization cone angle between the sub-nanometer atomizer and the ordinary atomizer, the scaling growth rate will increase. Faster, more frequent natural shedding. The length and ...
