(-----) June 2, 2022

Q. We're battling to prevent wrinkling/ crease/ buckling effect especially on thin wide material in our Continuous Galvanizing Line.

Strip is heated up to 680 °C and just before Galvanizing reduced to 460 °C. Some remedies helped but not always, including tension adjustments in the furnace or reduce the line speeds.

Our Main pot roll assembly is not adjustable WRT steering capabilities. We can only adjust the front stabilizing roll to create a tension differential in the pot area.

We are not experts to adjust the gain on our bridle tension controller which can help with any tension dips from prior tension zones etc.

Anyone have an idea what to do?
