The invention relates to the processes of working metals by pressure, namely to the processes of rolling wide sheets from the slabs with decrease of width (reduction) prior to their supply into the first stand of rolling mill. A method of reduction of hot slabs includes pressing of slab on the width by individual sections along the slab by two symmetrically installed rules, which are made with possibility of reciprocating motion perpendicularly relative to the longitudinal axis of slab. Pressing is achieved at the length of the deformation area, which makes not less than 0.8 of initial width of slab. The method provides for achievement of minimum nonuniformity of deformation on the height of slab and possibility of drawing the slab. A device for reduction of hot slabs includes two hydraulic cylinders, which are located symmetrically on both sides of the line of transport of slab to the rolling mill, on rods of which the rules for pressing of slabs on the width, and limiters of vertical bending of slabs are installed. The length of rules makes not less than 0.8 of initial width of slab. The limiters of vertical bending of slabs are made with possibility of contact with upper and lower surfaces of slab by their idlers. In this case upper limiters are made with possibility of vertical displacement, and lower limiters are installed permanently. The device provides for overlapping the lengths of adjacent pressed sections, and absence of bending of slab. The group of inventions provides for reduction of hot slab in any range of change of its width, decrease of the stock of crystallizers of installation for continuous casting of billets and increase of productivity of the process of reduction.
