Galvanized corrugated steel plate knife streak defect solution

The operator should not raise or lower the speed of the production line too much, and pay attention to the shape of the incoming plate. If the shape of the plate is poor, the spacing of the air knife should be adjusted in time, and the tension, calibration roll and stabilization roll should be adjusted to make the strip get a good flatness in the middle of the air knife nozzle to prevent the blockage of the strip scraper. If there are gas knife streaks, you can quickly open the gas knife when the weld passes and clean it with special tools.
