Description
Technical field
The present invention relates to a kind of powder metallurgical technique.
Background technology
Powder metallurgy is to produce metal dust or made with metal dust (or mixture of metal dust and non-metal powder)
For raw material, by shaping and sintering, the technology of manufacture metal material, composite and all kinds product.Powder smelting
Jin Fayu production ceramics have similar place, belong to sintered powder technique, therefore, a series of New Technologies In Powder Metallu Rgies also can use
In the preparation of ceramic material.The advantages of due to PM technique, it turns into the key for solving the problems, such as new material, in new material
Development in play very important effect.Powder metallurgy includes powder processed and product.Powder wherein processed is mainly metallurgical process, and word
Face coincide.And sintered metal product is then often far beyond material and metallurgical category, often across it is multidisciplinary (material and metallurgy,
Machinery and mechanics etc.) technology.Especially contemporary metal powder 3D printing [1-2], collection mechanical engineering, CAD, reverse Engineering Technology,
Layered Manufacturing Technology, Numeric Control Technology, material science, laser technology are so that sintered metal product technology turns into across more
The modern complex art of subject.Existing powdered metallurgical material non-refractory.
The content of the invention
(1) technical problems to be solved
The problem to be solved in the present invention is to provide a kind of powder metallurgical technique, to overcome lacking for non-refractory in the prior art
Fall into.
(2) technical scheme
To solve the technical problem, the present invention provides a kind of powder metallurgical technique, comprised the following steps：Step 1, will
Raw material carries out extruding crushing；Step 2, to die casting machine in carry out die casting；Step 3, obtain semi-finished product；Step 4, by semi-finished product
Carry out deburring；Step 5, semi-finished product are done into antirust treatment；Step 6, obtain finished product.
Further, in the step 2 temperature control of die casting machine at 190-520 degrees Celsius.
(3) beneficial effect
The powder metallurgical technique of the present invention, technique is simple, improves final product quality, more high temperature resistant.
Embodiment
With reference to embodiment, the embodiment of the present invention is described in further detail.Following examples are used for
Illustrate the present invention, but be not limited to the scope of the present invention.
A kind of powder metallurgical technique of the present invention, comprises the following steps：Step 1, raw material is subjected to extruding crushing；Step
Two, to die casting machine in carry out die casting；Step 3, obtain semi-finished product；Step 4, semi-finished product are subjected to deburring；Step 5, will be partly
Finished product does antirust treatment；Step 6, obtain finished product.The temperature control of die casting machine is at 190-520 degrees Celsius in the step 2.
The powder metallurgical technique of the present invention, technique is simple, improves final product quality, more high temperature resistant.
In summary, the restricted embodiment that it is the present invention that above-mentioned embodiment, which is not, all those skilled in the art
The modification carried out on the basis of the substantive content of the present invention or equivalent deformation, the technology category in the present invention.
