Abstract

The invention relates to the technical field of remelting, in particular to a remelting device and a remelting method. The remelting equipment provided by the present invention includes a workpiece carrying device, a remelting structure having a remelting part, and a remelting part adjusting device having a first adjusting device, wherein the remelting part adjusting device can not only control the realization of the remelting part Feeding in the direction of the central axis of the workpiece can also adjust the effective width of the remelted layer, by increasing the effective width of each single-pass remelting layer and / or keeping the effective width of different single-pass remelting layers consistent to increase the overlap. The amount of contact and / or improve the consistency of the amount of overlap, so that each overlap area is more fully melted, reducing the risk of cracks and / or weak areas in the workpiece, which is beneficial to enhance the mechanical strength and fatigue strength of the workpiece and improve the performance of the workpiece. Work reliability of the workpiece, prolong the service life of the workpiece.

Description

technical field [0001] The invention relates to the technical field of remelting, in particular to a remelting device and a remelting method. Background technique [0002] The use of thermal spraying technology to form a coating on the surface of the workpiece can improve the hardness and corrosion resistance of the workpiece, but due to the typical layered structure of the coating, there are tiny pores in the interior to varying degrees, and the combination with the substrate is mechanically combined. Therefore, the wear resistance and impact resistance of the coating are limited, and it cannot be applied to the harsh working conditions of heavy load and high impact force. The remelting treatment technology is an important technology to improve the comprehensive performance of the coating. It uses a heat source to melt the most easily fusible components in the alloy, and the generated liquid phase helps to strengthen the diffusion process and penetrate the components. The ...
