Section Rolling Mill Steel Plantech
With a universal rolling mill, when being applied primarily at the finishing stage of shaping, if the rolling speed is fast and the amount of pressure under the flange is not that big, there is slipping that occurs between the material and the vertical roll before the material undergoing rolling bites into the roll, and the vertical roll synchronizes with the rolling speed and begins turning.
