Cold Rolled Mill

As another type of cold forming process, cold rolled mill also works at room temperature to stretch large size pipe to required small size.
Comparing cold drawn mill ,it takes pilger mill with fewer cold forming processes and lower productivity, but come out the pie in much precise size and shinning apperance.
