Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat treatment, in particular to a processing method for processing steel ball sleeving sleeve ring by using a mesh belt furnace. BACKGROUND

[0002] When the mesh belt furnace processes the steel ball, the steel ball can only be scattered in one layer due to the limitation of the transmission structure. If the number of scattered layers is too much, the upper layer of steel balls will be extruded due to the shape and gravity of the steel balls, which will cause the displacement of the lower layer of steel balls on the mesh belt, and the heating time of the steel balls cannot be guaranteed. The production per hour is low when the steel balls of different sizes are processed by the mesh belt furnace, and the production per hour is only 329 Kg / h-454 Kg / h, as shown in the figure, which seriously restricts the production capacity of the mesh belt furnace, and there is no effective method to effectively release the processing capacity of the mesh belt furnace. Figure 1 SUMMARY

[0005] (1) heat treatment: the sleeve ring is kept at 851-852℃ for 51-52min in the mesh belt furnace and then oil quenched, and then tempered at 170-172℃ for 3-4h;

[0006] (2) feeding: evenly lay a layer of steel balls on the mesh belt of the mesh belt furnace, and sleeving a layer of sleeve rings on the steel balls;

[0007] (3) discharging: buffering the impact force when the product falls through the cushioning piece;

[0010] (6) shape measurement: the deformation and allowance of the sleeve ring meet the process requirements.

[0011] As a preferred scheme, the cushioning piece in step (3) is a wooden partition or a rubber plate.

[0012] As a preferred scheme, the sorting mechanism in step (4) is a screen mesh, the screen mesh has a plurality of screen holes, the diameter of the screen hole is greater than the outer diameter of the steel ball, and the diameter of the screen hole is less than the inner diameter of the sleeve ring.​

[0013] The beneficial effects of the present application are: 1. Based on the original mesh belt furnace which can only spread one layer of steel balls, the present application sets a sleeve ring on the upper layer of steel balls, improves the hourly output of the mesh belt furnace, increases the processing efficiency of the mesh belt furnace, and effectively releases the production capacity of the mesh belt furnace.
