Closed production line and method for zinc impregnation post-treatment

Abstract

The invention provides a closed production line for zinc impregnation post-treatment. The closed production line comprises a cleaning and cooling section, a closed section I, a discharging and cleaning section, a closed section II and a drying and cooling section, wherein the closed section I is arranged behind a discharging port of the cleaning and cooling section; the discharging and cleaning section is arranged behind a discharging port of the closed section I; the closed section II is arranged behind a discharging port of the discharging and cleaning section; and the drying and cooling section is integrated with the closed section II. According to the closed production line, continuous closed treatment of parts is achieved, the parts can automatically enter a follow-up closed treatment production line after entering the cleaning and cooling section, manual intervention is greatly reduced, the equipment automation degree is high, the production efficiency is improved through continuous closed treatment, and the closed production line is suitable for industrial production; and in addition, closed treatment is conducted twice on the parts through the closed section I and the closed section II, so that the corrosion resistance, corrosion resistance and other performance of the parts are greatly improved. The invention further provides a closed production method.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a closed production line and method for zinc sherardizing post-treatment. Background technique [0002] As we all know, the application environment of most engineering parts is complex, and they are prone to rust and corrosion in harsh environments for a long time, and their service life is short. Therefore, in order to solve this problem, it is necessary to sherardize the parts The main principle of the treatment is to put the zinc-seeding agent and the parts into the zinc-seeding furnace, heat to a certain temperature, and the active zinc ions penetrate from the surface agent to the inside of the parts, and at the same time, the iron atoms diffuse from the inside to the outside, and on the surface of the parts A galvanized layer is formed, which can guarantee the performance of the parts. Although after galvanizing treatment, the parts have a certain a...

[0002] As we all know, the application environment of most engineering parts is complex, and they are prone to rust and corrosion in harsh environments for a long time, and their service life is short. Therefore, in order to solve this problem, it is necessary to sherardize the parts The main principle of the treatment is to put the zinc-seeding agent and the parts into the zinc-seeding furnace, heat to a certain temperature, and the active zinc ions penetrate from the surface agent to the inside of the parts, and at the same time, the iron atoms diffuse from the inside to the outside, and on the surface of the parts Form a galvanized layer, which can ensure the performance of parts

Although the parts have certain corrosion resistance after galvanizing treatment, the effect is general. Therefore, in order to further enhance the rust and corrosion resistance of the parts, it is necessary to seal the parts.

[0003] Since there are many sealing processing steps and manual intervention, continuous and uninterrupted sealing processing cannot be realized. Therefore, in order to overcome the above technical problems, it is urgent to design a continuous sealing production line
