Abstract
Apparatus and method for roll crossing and shifting in which work roll chocks are mounted between Mae West blocks, the chocks and Mae West blocks being provided with opposed contact surfaces defining an angle .beta. to the roll axis, whereby, when the rolls are axially shifted, the rolls also cross, through an angle .alpha., due to forces acting on the chocks as they move along the contact surfaces of the Mae West blocks.
Claims18
An improved roll shifting and crossing system comprising a rolling mill housing, at least one pair of upper and a lower work rolls having roll necks mounted in chocks each of which is supported by a pair of upside and downside Mae West blocks mounted in the housing, each of said chocks and the associated Mae West blocks having between them a pair of opposed contacting surfaces having a variable slope and defining an angle .beta. with respect to the roll axis and which surfaces, upon axial shifting of the work roll, causes at least one roll chock of each roll simultaneously to move in a direction perpendicular to the roll axis resulting in crossing of each pair of rolls at an angle, .alpha., to the pass line of the mill, and means to axially shift the work rolls.
A method of roll axial shifting and crossing comprising mounting at least one pair of upper and lower work rolls in chocks enclosing necks of each roll and supported by a pair of upside and downside Mae West blocks, said roll chocks and associated Mae West blocks having opposed contact surfaces having a variable slope and defining an angle .beta. with respect to the roll axis, mounting each roll chock with the contact surface thereof between the contact surfaces on the associated Mae West blocks, axially shifting the rolls and simultaneously crossing the rolls through an angle .alpha. by means of forces acting between the contact surfaces of the chocks and the Mae West blocks.
