摘要：PURPOSE:To permit a considerable change of a sheet width and to obtain a
product having high width accuracy in a titled method for controlling the tension of a
material to be rolled by further adjusting the width of the material to be rolled, which is
not thoroughly controlled by the tension between stands, by a vertical rolling mill.
CONSTITUTION:An arithmetic unit 18 for tension predicts and calculates the temp. and
width of the material 10 in accordance with the temp. and width of the material 10 to be
rolled measured by a thermometer 12a and a width gage 14a and the input from a
process computer 16 and calculates and determines the target tension between the 1st
and 2nd stands. A tension control device 26 calculates the tension of the material 10
upon arrival of the part (P) to be measured of the temp. and width of the material 10 at
the spacing between the above- mentioned stands and changes the reference speed of
the 1st stand so that the tension coincides with the above-mentioned target tension. An
arithmetic unit 30 for the position of an edger determines the deviation between the
actual width from the gage 14b and the target width on the inlet side of the 2nd stand in
the part P from the unit 18. The unit 30 determines the roll gap of the edger necessary
for eliminating the above-mentioned deviation by taking the cross rolling reduction
efficiency of the edger 28 into consideration in accordance with the deviation and the
temp. of the part P and controls the position of the edger 28.
