Rolling mill

A rolling mill comprising:

• an upper and a lower work roll arranged to contact a strip or workpiece for rolling the same;
• metal chock means for rotatably supporting each end of said upper and lower work rolls;
• work roll bending means for applying a roll bending force interposed between the metal chock means of said upper work roll and the metal chock means of said lower work roll;
• an upper and a lower backup roll arranged in a position outside of the associated upper and lower work rolls;
• metal chock means for rotatably supporting each end of said upper and lower backup rolls;
• an upper and a lower guide frame arranged in a position outside of each of said backup rolls on a side thereof remote from the associated work roll, said guide frames each extending over a width of respective roll surfaces of the upper and lower backup rolls at a spacing from the respective roll surfaces and contacting said metal chock means for said upper and lower backup rolls so as to transmit a rolling force applied to said upper and lower guide frames to said upper and lower backup rolls through said metal chock means for said backup rolls;
• and
• means for axially displacing said upper and lower backup rolls in an opposite direction to bring a side edge of an effective roll surface of the respective backup rolls substantially in vertical alignment with respective side edges of the strip or workpiece.
