[0002] At present, the vertical loop on the strip continuous hot-dip galvanizing production line is used to store strip steel. Taking the outlet loop as an example, when the coiler needs to stop for discharging, due to continuous galvanizing, the outlet loop stores the strip steel produced on the production line into the outlet loop.
