METHOD FOR HOT STRIP ROLLING AND WIDE STRIP ROLLING MILL FOR PERFORMING THE SAME Russian patent published in 2000 - IPC

FIELD: manufacture of hot rolled strips from continuously cast slabs in wide strip rolling mills in ferrous and non-ferrous metallurgy. SUBSTANCE: method for hot strip rolling comprises steps of multiple plastic deformation of slab by thickness and width; realizing local cross plastic bending of separate portions of rolled piece; deflecting cross section of rolled piece upwards from its position after deformation between horizontal rolls. Wide strip rolling mill includes at least one rolling stand with vertical rolls and one rolling stand with horizontal rolls forming rough rolling stand group and finish rolling stand group and coilers. Rolling mill includes apparatus for local cross plastic bending of rolled piece placed at side of feeding rolled piece for deforming between vertical rolls. EFFECT: enhanced reduction between vertical rolls without loss of stability of rolled piece. 5 cl, 12 dwg
