Abstract
A method of rolling a metal plate from an ingot or thick slab (1,2) includes setting a work roll gap with a mechanical screw (24) and rolling the ingot or slab through a first pass to produce a rolled product (21). The rolled product (21) is removed from the roll gap and the mechanical screw (24) is used to set a reduced roll gap (34a). The rolled product (21) is rolled through the reduced roll gap (34a) over a partial pass extending over less than the full length of the rolled product (21), to form a further rolled product (22, 21); and the further rolled product is removed from the roll gap. Repeat prior step. Then turn the rolled plate and carrying out a further roll pass in a width direction of the plate.
