[0017] Specific implementation mode three: the following combination image 3 and Figure 4 This embodiment will be specifically described. In this embodiment, on the basis of Embodiment 1, the following operations are added in step 2: the collected alloy particles are loaded into the alloy shell 5, the alloy shell 5 is in the shape of a round cake, and the alloy in the alloy shell 5 A disc-shaped cover 6 is added to the top of the particles, the outer diameter of the cover 6 is the same as or slightly smaller than the inner diameter of the alloy shell 5, and the upper surface of the cover 6 is flush with the upper edge of the alloy shell 5; then the alloy shell The body 5 is placed into the die cavity 2 of the mechanical press. The gap between the outer diameter of the alloy shell 5 and the inner diameter of the die cavity 2 is 1 to 2 millimeters. The material of the alloy shell 5 can use the same composition as the alloy particles. Of course, in order to improve the plas...

Abstract

The invention provides a preparing method of a spheroidizing agent pressing block, and relates to a preparing method of a spheroidizing agent block body with alloy components. The problem that a device in the prior art is complex is solved. The method comprises the following steps that firstly, alloy particles with the grain diameter being below 5 mm generated in the production process of a spheroidizing alloy block body are collected; secondly, the collected alloy particles are loaded into a pressure mold cavity of a mechanical pressure machine, and the pressure mold cavity is cylindrical; thirdly, a downward pressing punch of the mechanical pressure machine applies pressure downwards under the hydraulic force effect, and the alloy particles in the pressure mold cavity are pressed into acake; fourthly, the downward pressing punch of the mechanical pressure machine is lifted up, the lower punch, used for closing the lower bottom face of the pressure mold cavity, of the mechanical pressure machine ascends under the effect of hydraulic force, and enters the closed pressure mold cavity, and the cake formed through pressing of the alloy particles is ejected out of the pressure mold cavity, and mold releasing is finished. A large amount of alloy particles plastically deform under the pressure, and are pressed into the cake whole body, and use by customers and an enterprise is facilitated.

Description

technical field [0001] The invention relates to a method for preparing a spheroidizer block of an alloy composition. Background technique [0002] During the smelting and production process of nodulizer alloys, industrial enterprises will produce about 8% of small alloy particles with a particle size of less than 5mm; this is because the large nodulizer alloys after smelting are broken to standard particle sizes according to customer needs , produced by-products. However, a large number of customer companies do not use small-particle alloys, resulting in the current large amount of alloy powders that need to be smelted again to be recycled. On the one hand: the recycling of smelted alloy powder has oxidation loss of alloy components and dust pollution in the smelting production process; on the other hand, the recycling cost of this method is relatively high. [0003] The utility model patent with the authorized announcement number CN 206794762U discloses "A kind of alloy b...
