In recent years, coating operations have been widely used in various industries because coatings are no longer just beautification functions. Applying coating technology to various parts or steels can increase their physical characteristics, isolate external corrosion, and extend service life. China Steel Group's current film thickness measurement technology has been used in various coating production lines such as insulating coatings, anti-fingerprints, passivation films and anti-rust oil coatings, providing on-site grasp of the coating thickness and exerting quality management effects. This system uses a film thickness gauge mainly based on infrared or X-Ray penetration principle, and cooperates with mechanism design and control, and uses reciprocating mobile scanning of the moving steel coil to collect the coating information of the steel coil, and cooperates with film thickness software to display and analyze the film thickness software in real time. In addition to immediately displaying the real-time scanning results, the collected steel coil film thickness information is presented in a simple and easy-to-understand graphical interface, making it easy to distinguish the distribution of the steel coil coating.
Problems derived from inaccurate film thicknessCost of coating: If the coating is thick or wrong, wastes the cost of coating
Process control: slow feedback speed, unsuitable to optimize the film thickness
Product quality: The coating film is too thick, downstream processing is depowdered, the coating film is too thin, and the steel sheet is prone to rust
System introductionIncident light polarization, dual detector, high stability
The measurement rate is 8000RPM, and the film thickness is representative.
Both organic coating film and anti-rust oil film are suitable
