Abstract
The invention relates to a method for preparing high-stacking-density oblate powder material. A preparing device comprises a smelting furnace (1), an induction coil (2), a gas atomizer (3), a atomization tower (4), a atomization tower base (5), a rotating bearing (6), a driving chain wheel (7), a double-layer cooling water device (8) and a connecting discharging collecting device (9). The method is characterized in that atomized gas is used for impacting and dispersing metal liquid smelted in the smelting furnace into tiny liquid drops, and before complete solidification and nodulizing, the liquid drops impact the inner surface of the atomization tower, deform and is rapidly cooled and solidified to obtain the high-stacking-density oblate powder material. The method has the advantage of being capable of preparing the high-stacking-density oblate powder material.
Description
Technical field
The present invention relates to a kind of utilization by specially designed process equipment, integrated atomized molten method and quick cooling method are prepared the method for the oblate sprills material of high-bulk-density.
Background technology
Along with the development of the quiet moulding pressure technology such as metal 3D printing technique, surface cladding reparation re-manufacturing technology, dusty material, other powder metallurgic method parts manufacturing technologies, its raw material powder product chemical purity, pattern, density, mobility, granularity and size distribution are had higher requirement.The shape characteristic of dusty material has determined mobility and the bulk density of dusty material to a great extent, and high fluidity and high-bulk-density are more conducive to forming material powder, and compact density is high, and even density, and dusty material sintering is more densified.The dusty material bulk density that facts have proved oblate shape pattern is maximum, exceedes the irregular dusty material of pattern and spherical powder material.
The mode of production of powder-product and equipment now, or be to produce profile irregular powder material, as water atomization and the ball-milling method mode of production; The spherical shape of rule, as high pressure gas atomization method and the spray granulation mode of production.
Utilization of the present invention is by specially designed process equipment, and integrated atomized molten method and quick cooling method are prepared the method for the oblate sprills material of high-bulk-density
Summary of the invention
The object of the invention is to solve the restriction that can only produce now irregular powder material and spherical powder material, invented the melt-processed raw material of a kind of employing mode of heating, integrated aerosolization method and quench are prepared the method for the oblate sprills material of high-bulk-density.
Technical scheme of the present invention is: prepare in dusty material process in atomization, raw material liquid line by the mode such as resistance or induction or electric arc or high-temperature plasma heat fused is dispersed into fine droplet by mechanical force or the impact of atomization gas medium, fine droplet flies cooling in a specially designed Sloped rotating atomisation tower, before solidifying, be subject to surface tension effects, drop is nodularization gradually, before solidifying nodularization completely, drop clashes into atomisation tower inner surface, deform and rapid cooled and solidified, cooling velocity reaches 10
5-10
7k/S, obtains the oblate sprills material of high-bulk-density.For preventing that powder from mutually boning and being bonded on atomisation tower surface, atomisation tower is designed to Double water-cooled structure, rotates, and for controlling the flight cooling velocity of atomized drop, passes into inert gas or the air of controllable process temperature in atomisation tower.
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing explanation
Fig. 1 is the structural map of apparatus of the present invention.
In figure: 1. melting and the bottom pour ladle harp that unites two into one, 2. induction coil, 3. gas atomizer, 4. atomisation tower, 5. atomisation tower pedestal, 6. rolling bearing, 7. drive sprocket, 8. Double water-cooled device, 9. connects discharging gathering-device.
specific embodiment technical approach
Production technology of the present invention is that one heats by induction mode, by the metal molten in smelting furnace, the material liquid line of fusing is dispersed into fine droplet by mechanical force or atomization gas medium, and fine droplet flies cooling in a specially designed Sloped rotating atomisation tower, before solidifying, be subject to surface tension effects, drop is nodularization gradually, and before solidifying nodularization completely, drop clashes into atomisation tower inner surface, deform and rapid cooled and solidified, obtain the dusty material of oblate outward appearance.
Processing metallic is generally used the method for induction melting, according to the different melting points of rapidoprint, also can select resistance or electric arc or the melting of high-temperature plasma heating means.According to technological requirement, select different types of rapidoprint melting environment, can be vacuum or protective gas environment, as argon gas, nitrogen, oxygen, air etc.To heat to describe the present invention in conjunction with induction mode below.
Heat by induction coil 2, by the metal molten in heating furnace 1, molten metal liquid forms liquid line by the metering hole of smelting furnace crucible bottom pour ladle and pours into a mould downwards, the harp 1 that smelting furnace and transition heating bottom pour ladle also can be designed to unite two into one; Metal material after fusing is broken up into droplet through the atomization gas focus of atomizer 3 and enters atomisation tower 4; In flight course, be subject to surface tension effects nodularization gradually, before solidifying nodularization completely, hit atomisation tower wall inner surface, deform and rapid cooled and solidified, obtain the oblate sprills material of high-bulk-density.For quick cooled and solidified, and prevent that powder from mutually boning and being bonded on atomisation tower inner surface, atomisation tower is designed to Double water-cooled structure 8, by the effect of rolling bearing 6 and drive sprocket 7, on atomisation tower pedestal 5, rotates; For controlling the flight cooling velocity of atomized drop, in atomisation tower, pass into inert gas or the air of controllable process temperature.The powder of preparation, in the cooling landing deposition of atomisation tower system inwall, concentrates on atomisation tower outlet at bottom 9 and collects.
Waste gas after atomization is filtered and purifies recycling or environment protection standard discharge.
The oblate powder of series prepared by the method for foregoing invention can be metal simple-substance or metal alloy powders material, can be also various nonmetallic powder material.
