Abstract
The utility model discloses a quick freezing device for metal, which can manufacture the microcrystal powder granules of the metal or flakes. The structure of the quick freezing device for metal is that the upper part of the quick freezing chamber is provided with a casting cup and a press head; the external side of the casting cup is provided with the external cover of the protective gas; the metal liquid can be ejected on an impeller disk which conducts the high-speed rotation through a nozzle; the metal liquid is excited to be the microcrystal powder granules or the flakes through the cold forming, and in addition, the quick freezing chamber is also provided with a spraying annular pipe and a metal pipe which are injected with the cooling medium. The quick freezing device for metal is suitable for producing all kinds of quick freezing alloys.
Description
The utility model relates to a kind of equipment that obtains solidified metal microcrystalline powder or thin slice.
Announced a kind of preparation facilities of metal fine powder among the clear 63-221831 of day disclosure special permission communique (A); be characterized in that one horizontally rotates impeller; an and perpendicular nozzle; this patent does not relate to the cooling problem of rotating disk; there is not the protective gas cover in addition around the nozzle; metal liquid stream is gravity-assist pouring, and speed is not high, so metal dust cooling velocity not high (＜10
5K/S), degree of oxidation is more serious.
The production metal powder device that the clear 59-159903 of day disclosure special permission communique (A) announces, its cooling substrate is tapered CD, its hitting power to metal liquid stream is little, so cooling velocity is not high yet.
The purpose of this utility model is to provide a kind of can improve the metal cooling velocity, reduces the preparation microcrystalline powder of degree of oxidation or the quick solidification apparatus of thin slice.
Thereby the utility model device is to realize rapid solidification by hitting metal liquid stream near cold metal blade in the high thermal conductivity of nozzle.
The utility model device is as shown in Figure 1: be placed with in rapid solidification chamber (9) top hold metal liquid (3) water cup (1), water the cup top one ventilation pressure head (11) is arranged, water the outer cover (2) that logical protective gas is equipped with in cup (1) outside, water the cup (a 1) bottom one nozzle (4) is arranged, there is a metallic impeller dish (5) below of nozzle (4); Inwall in rapid solidification chamber (9) has the spray ring pipe (6) of a logical cooling medium in addition, and the metal tube (7) of an injection cooling medium is arranged above the metallic impeller dish.
The utility model is to realize rapid solidification like this: water under the gas pressure effect of metal liquid (3) in pressure head (11) in the cup (1); form the liquid fluidization tower by nozzle (4); this liquid fluidization tower is passed into the protective gas protection in the protective gas cover (2); and the blade on the metallic impeller dish (5) that is rotated at a high speed soon hits; disperse; be frozen into powder or thin slice tangentially flies out along blade; these powders or thin slice flow under the cooling medium of ring pipe (6) ejection impacts and collect mouthful (10); at the same time; also cooling medium can be sprayed from the mouth of pipe (7), in order to cool metal blade and metal powder grain and thin slice.
This device characteristic is that the free travel of metal liquid stream is short, and cut apart, hit by the high interior cold blade of thermal conductivity, solidify with the solid dielectric heat-conducting mode, the rotating speed of impeller is 3000～7000 rev/mins, and impeller diameter is φ 180mm～280mm, thickness 10～20mm, make with fine copper or copper alloy, also other metal material of available other good heat conductivity is made, in addition blade surface also the method handled of usable surface increase the blade thermal conductivity, improve peptizaiton to metal fluid.The utility model device, cold blade has the hitting power of 4MPa in it to metal liquid stream, its cooling effect is higher than the ultrasonic atomizatio method fuel pulverizing plant that revolves casting device and fluid media (medium) heat conduction of solid dielectric heat conduction, and its oxidated layer thickness is equivalent to vacuum gas atomising device effect built in～5nm.This device hourly output is 30kg, and its granularity is adjustable.
