Embodiment Construction

[0024] Such as figure 1 As shown, a melting powder process for electrostatic powder spraying on the surface of steel doors, a horizontal suspension transmission chain 1 is set, its rear end (left side in the figure) is connected to the electrostatic spraying equipment on the production line, and its front end (figure Middle right side) runs through an induction coil 3; the induction coil is connected with an intermediate frequency induction generator 4, and the intermediate frequency induction generator applies a specific intermediate frequency electromagnetic field to the induction coil 3 through a control box 5. The steel doors 2 to be melted powder that have been sprayed with electrostatic powder are suspended at equal intervals on the transmission chain. The steel doors 2 to be melted powder are suspended on the transmission chain in a horizontal manner, and follow the transmission chain to move from the rear end to the front end at a uniform speed, and enter one by one. T...

Abstract

The invention discloses a process for electrostatic powder spraying of melted powder on a steel door surface. The process is characterized in that after performing steel door electrostatic spraying on a production line, a medium frequency induction heating device is arranged for performing induction heating on the steel door with a special medium frequency induction heating coil. The purposes for electrostatic powder spraying and heating the welded powder on the steel door surface and solidifying the decorative surface are realized.

Description

technical field [0001] The invention relates to a method for decorating the surface of a steel door, in particular to a method for heating the surface of the steel door after electrostatic powder spraying. Background technique [0002] At present, the heating treatment method used for electrostatic powder spraying on the surface of steel doors usually adopts the baking process of heating furnace (resistance furnace, oil heating furnace, gas furnace, coal furnace, etc.). (surface) to the inner layer (door body) melting powder and solidification, so the quality of the finish is extremely unstable, sometimes the inner layer has not been completely melted, but the surface coating flows due to overheating, resulting in uneven and uneven adhesion of the finish Stable, often delaminated and peeled, seriously affecting the quality of the finish of the steel door. In addition, the equipment (furnace body) required by the traditional baking process has a large footprint, high energy ...
