Example Embodiment
[0032] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.
[0033] like Figure 1 to Figure 12 As shown, the manufacturing method of the wear-resistant layer of the screw barrel of the present embodiment includes the following steps:
[0034] 1. Add wear-resistant powder to the inner cavity of the barrel 4 for making the wear-resistant layer, and close the openings at both ends of the barrel 4 after the wear-resistant powder is loaded;
[0035] 2. Transfer the barrel 4 to a heating furnace with a temperature of 1000-1300°C for heating. When the barrel is heated in the heating furnace, the barrel keeps rotating radially and moving back and forth in the axial direction, so that the resistant material placed in the inner cavity of the barrel 4 can be heated. The grinding powder is uniformly melted in the inner cavity of the barrel and covers the inner peripheral surface of the inner wall of the barrel, ...
