Abstract
The utility model discloses a gas atomization device of refractory powder and provides a processing device in which high pressure gas atomization is utilized to prepare alloy powder. The structure of the original gas atomization device is reformed, a connecting pipeline is provided with three three-way pipes respectively connected to a front end, a middle lower part and a rear end of a gas atomization mixer, the front ends of the three-way pipes are connected to the same gas inlet, the rear ends of the of the three-way pipes are connected to the same gas outlet, refractory powder and high pressure gas are uniformly sprayed out by the gas atomization mixer to form gas and powder composite media, and melted alloy liquid is crushed to achieve the organic combination of the refractory powder and alloy droplets.
Description
Technical field
The utility model relates to field of powder metallurgy, is specially a kind of aerosolization device that utilizes the refractory powder that the gases at high pressure aerosolization produces alloy powder.
Background technology
The production principle that alloy powder is produced in aerosolization is the alloy with high temperature melting, utilize gases at high pressure, through gas atomization device, be atomized into the ball-type body of powder below 150 microns, utilize powder collection device, gas, powder are separated, and, can be made into the spherical alloy powder of various particle size ranges and various composition requirements through screen analysis.
Because infusibility melting point substance height, the aerosolization method can't adopt inert gas to carry out fragmentation the infusibility material, also just can't be with indissoluble material alloying or coating, simultaneously the new dielectric formed of gas, infusibility powder to pipeline and equipment by force towards the gentle pipe plug plug of loss, and new dielectric gas, the uniformity of powder, fluency also will be affected.
The utility model content
The technical problem that the utility model solved is to provide a kind of aerosolization device of refractory powder, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
The aerosolization device of refractory powder, original aerosolization device structure is transformed, utilization gas, powder mixer, the infusibility powder is evenly sprayed with gases at high pressure, form gas, powder synthetic medium, the alloy liquid that melts is carried out fragmentation, reach the combination of infusibility powder and alloy liquid droplet.Be provided with front end, middle lower portion and the rear end that three three-way pipes are connected respectively to the aerosolization blender on its original again connecting pipe, described three-way pipe front end is connected to same gas access, and the rear end connects same gas vent; In addition, connect the three-way pipe place in aerosolization blender lower end and also should be provided with a wide-mouth nozzle.
Because new dielectric is made up of gas and solid, effectively combination, than being easier to cause tracheae to stop up or because the infusibility powder causes badly damaged sweeping away by force of gases at high pressure to the equipment matrix, therefore, the infusibility powder is except should selecting the powder of particle diameter less than 20um, also must guarantee the uniformity of external powder feeder powder feed rate, and control by the pressure regulator valve that is installed on the connecting pipe.
Beneficial effect: the utility model technology is simple, easy to process, assembling easily, simple to operate, can be effectively that the infusibility powder is organic in conjunction with (cohering) by fusible alloy aerosolization mode, simultaneously can guarantee that the infusibility powder evenly coats fusible alloy spherical powder surface, produce the special powder of property, as the sphere powder etc. of milling.
