摘要： A process and apparatus for rolling a metal product (5) in a "four-high" type rolling mill comprising two work rolls (1) and (2) interposed between two backup rolls (3) (4) at least one of which is of the variable camber type having a cylindrical casing (33) mounted on a central shaft (31), the profile of the casing (33) being adjustable. The other backup roll (4) is a simple solid coacting roll whicl deforms freely under the action of the pressure load to form a line of support (47) which is concave in the direction of the roll pass (50). The deformation of the casing (33) of the variable camber backup roll (3) is controlled so as to form a line of support (37) which is convex in the direction of the roll pass (50) and substantially parallel to the line of support (47) of the coacting roll (4), and the camber of the work roll (1) is adjusted so as to maintain a constant thickness of the roll pass over the entire width of the product (5), the latter on leaving the rolling mill having an incurved transverse profile capable of being subsequently corrected.
