Patent ID: 6959571

Claim:
A rolling mill, comprising: a housing; upper and lower rolling rolls rotatably supported by the housing via roll chocks; screw down means provided in an upper portion of the housing and adapted to apply a predetermined pressure to the rolling roll; pressing means for thrusting the roll chocks along a transport direction of a rollable material to press the roll chocks against the housing; end portion detecting means for detecting an end portion of the rollable material which is traveling; rolling force detecting means for detecting a rolling force by the rolling rolls; and control means which, based on results of detection by the end portion detecting means, sets a thrusting force by the pressing means at a first value prior to engagement of the rollable material between the rolling rolls, maintains the first value, and, upon detection of the engagement by the rolling force detecting means, sets the thrusting force at a second value, lower than the first value, wherein based on the results of detection by the end portion detecting means, the control means sets the thrusting force at a third value, higher than the second value, before passage of a rear end of the rollable material between the rolling rolls.
