Principle of induction remelting:
The special spraying gun is used to spray the alloy powder on the surface of the workpiece, and then the coating is remelted (flame or induction) to form a metallurgical combination with the substrate, and the coating can achieve wear resistance, high temperature resistance, oxidation resistance, corrosion resistance and other process properties
Solution 1
HVOF flame spraying automatic remelting integrated device and method of use thereof,
The machine comprises a rotating bed body and a moving slide frame arranged in front of the rotating bed body; The two ends of the rotating bed body are respectively provided with a rotating chuck and a tailstock center for positioning the workpiece, so that the front end of the workpiece is installed on the rotating chuck and the end is installed on the tailstock center; The upper surface of the rotating bed body is equipped with a bracket for holding the shaft head of the workpiece, so that the workpiece can rotate stably around the axis; The moving slide frame is provided with a powder spraying device, a remelting device and a temperature control device. The automatic remelting integrated device and its use method ensure the reliability of the system and effectively reduce the maintenance and scrap of products caused by manual errors; At the same time, due to the automatic control system, the labor intensity is reduced, the scrap rate of products is reduced, and the production efficiency is improved.
