Technical Field

Background

The zinc impregnation technique of powder is a new method of preventing corrosion by making use of the principle of metal atom diffusion in a thermal state to make zinc powder contact with a metal workpiece below a melting point, thereby forming a zinc-iron alloy protective layer on the surface of the metal workpiece to prevent atmospheric corrosion. When the device works, a metal workpiece, zinc powder, quartz sand, a plurality of permeation aids and other materials are mixed together and placed in a sealed container, after heating and heat preservation are carried out for a certain time at a preset process temperature, zinc atoms permeate from the surface of the metal workpiece to the inside, and iron atoms diffuse from the inside to the outside, so that a uniform zinc-iron compound layer, namely a zinc-permeated layer, is formed on the surface layer of the metal workpiece, and the metal workpiece is protected by the zinc-permeated layer.

At present, the powder zinc impregnation treatment of the surface of a metal workpiece is mainly to load the metal workpiece, zinc powder, quartz sand and various permeability aids into a sealed rotatable zinc impregnation tank, then the sealed zinc impregnation tank is hoisted into a hearth body, a roller motor drives the zinc impregnation tank to rotate, the zinc impregnation tank is heated at the same time, after the treatment is carried out for a preset time at a preset temperature, a heating element is closed, the zinc impregnation tank is cooled to the preset temperature along with a furnace, then the roller motor is closed, the zinc impregnation tank is hoisted out, and finally the zinc impregnation tank is opened to take out the treated workpiece.

In the existing zinc impregnation mode, furnace filling and sealing operations are required before zinc impregnation, cooling, unsealing and discharging are required after treatment, so that the zinc impregnation treatment has long invalid time, a large amount of heat energy is lost in the processes of temperature reduction and temperature re-rise, the temperature rise time of a powder zinc impregnation process is about 2-3 hours in the process of reaching a preset temperature, frequent temperature rise and temperature reduction wastes a large amount of heat energy and can cause environmental pollution, the environment-friendly trend of energy conservation and emission reduction is not met, and the temperature control and treatment time of each furnace product cannot be uniform due to furnace-by-furnace treatment.
