Embodiment Construction

[0008] The alloy powder agglomerate treatment method of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples (taking iron alloy powder as an example).

[0009] In this alloy powder agglomerate processing method, a binder that enables it to be formed is added to the powder, and a spherical or cylindrical agglomerate 2 is made by a method like making a core, and then the agglomerate is fully dried, and the iron tongs 5 ​​are used to dry the agglomerate. Clamp one end of the core bone 1 of the agglomerate, dip it into a ladle containing a molten metal with a higher melting point than the powder material, and then lift it out, and immediately form a layer of metal that has a uniform thickness like fried shrimp skin and has a higher melting point than the powder material. Metal shell; make a spherical or cylindrical agglomerate by a method like core making, and form the metal shell by dipping in a ladle of molten ...

Abstract

The invention discloses an alloy power clump processing method, comprising the following steps: adding a binder which can mold the powder into the powder, preparing a spherical or cylindrical clump by using the similar method for making core, then drying the clump fully, and clamping one end of the core bar of the clump by pincers, dipping the clump in a pouring ladle containing mental liquid with higher melting point than the power material and extracting the clump, thereby immediately forming a layer of shrimp skin-liked metal shell with uniform thickness and with higher melting point than the power material. If the alloy powder clump is taken as alloy scrap to be added into a furnace burden, the alloy powder clump can not burn and fly in the melting process, and the utilization rate of the alloy powder clump is high.

Description

technical field [0001] The invention relates to a method for processing alloy powder agglomerates. Background technique [0002] Some types of alloy powders are produced during the transportation and production of raw materials in the foundry industry. Especially in recent years, with the increase of industrial environmental protection awareness, the awareness of the importance of circular economy and the large amount of various alloy powders produced by mechanical chip processing The remelting of metal powder is used to reduce the production cost of castings, and people have stepped up the research on the remelting of alloy powder. At present, foreign countries generally use various powders to be classified and injected into the press chamber of the hot-temperature press, and formed into pellets or cylindrical blocks under certain pressure and temperature conditions, and then treated as smelting recycling materials. Although the effect of this method of using powder is goo...
