摘要：
A multi-row rolling mill has in one housing at least two groups of rolls including at least one pair of work rolls, and constructed so that when the workpiece to be rolled is passed one time, it can be rolled using said respective work rolls. The multi-row rolling mill is characterized in that it is provided with a means for removing the workpiece if the workpiece stops moving between said roll groups.
