The basic operation process of automated production of vacuum coating machine

With the development of vacuum skills and data skills and the urgent request of the steel industry for new steel products, strip vacuum coating is becoming a primary skill in strip steel surface treatment, with excellent prospects for development.

Nowadays, the steel belt vacuum coating technology that has become sophisticated and can be industrialized is the electron beam steel with vacuum coating.

1. There is a lot of optional coating information and is not subject to the melting point of the data. Therefore, in addition to the galvanizing, aluminum, and tin commonly found in hot-dip galvanizing, almost all metal materials can be vapor-deposited, and many kinds of metal nitride films, metal oxide films, metal carbides, and various composite films can be plated. This provides a great deal of freedom for the development of new strip steel materials.

2. High utilization rate of coating materials and low environmental pollution. Vacuum coating is a dry coating with no harmful liquids or gases.

3, strip steel coating quality, can achieve a uniform, smooth and extremely thin coating, high purity coating, corrosion resistance and adhesion. Before the steel strip is coated, it can be preheated by electron beam pre-heating. The coating has high purity, no central hard and brittle alloy layer, can be stamped and formed at one time, and can even be rolled into a tube that passes through very small tubes without falling off the plating layer.

4, sensitive skills, easy to change the variety, can be based on the request of the goods to complete the plating on the steel strip single-sided, double-sided, single-layer, multi-layer, can be plated together to reach the plating film. The coating thickness is easy to handle and can be coated with ultra-thin film.

Before using the vacuum coating machine, you must read the instruction manual carefully, familiar with the structural principle of the whole machine, the function and operation method of each component. 

1. After confirming that the water, electricity and gas have been installed correctly, first run the slide valve pump and the Roots pump, and the direction of rotation should be consistent with the direction specified by each pump. 

2. Check whether the power transmission devices of the equipment are operating normally.

3. Check the starting condition of the winding car, check whether the sealing of the winding car and the vacuum tank is reliable, check whether the various travel switches mounted on the guide rail are working properly, and check whether the placement and positioning of the track are in good condition. 

4. According to the order from low vacuum to high vacuum, the vacuum system is debugged step by step to check whether the sealing of each link is reliable, whether the opening and closing of each valve is flexible, whether the position of the Hall switch is correct, and each vacuum pump should run smoothly without abnormal vibration. No abnormal noise.
