Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
96 words
IN A METHOD OF ROLLING HOT ELONGATED WORKPIECES, SUCH AS STRIP, IN A TRAIN OF ROLLING MILLS FOR REDUCING THE THICKNESS OF THE WORKPIECES, WHEREIN A TEMPERATURE DIFFERENTIAL EXISTS BETWEEN LENGTHWISE PORTIONS OF THE WORKPIECES, COMPRISING THE STEPS OF: DETECTING A DIFFERENCE IN TEMPERATURE BETWEEN TWO LENGTHWISE PORTIONS OF THE STRIP, DETERMINING THE AMOUNT OF SAID DIFFERENCES, AND ADJUSTING THE SPEED OF THE TRAIN COMMENSURATE WITH SAID AMOUNT TO REDUCE SAID TEMPERATURE DIFFERENCE BY REDUCING THE CONDUCTION AND RADIATION LOSSES OF THE PORTION OF THE STRIP HAVING THE LOWER TEMPERATURE AS IT PASSES THROUGH THE TRAIN.
