Abstract

PURPOSE:To greatly improve the buckling limit of the slab, and to increase the breadthways rolling reduction, by installing the upper and lower push rolls made possible to adjust their roll gap in the direction of thickness, near the vertical roll provided with the lower flange. CONSTITUTION:The upper push roll 3 is vertically moved in order to make the roll gap of the upper and lower push rolls 3, 4 to approximately coincide with thickness of the material S just passing the vertical rolls 1, 1; and the top level of the lower push roll 4 is approximately aligned to the passing level of the material S. The vertical rolls 1, 1 are driven to perform the edging work. The vertical movement of the material S is restrained by the push rolls 3, 4: and the downward movement of the left and the right ends of the dog done is restrained by the lower flanges 2, 2 of the vertical rolls 1, 1; under this condition, the edging work is performed. Since the buckling of the material S is prevented by the rolling mill of the present invention, even in case of the large thickness-breadth ratio, the breadthways rolling reduction can be increased.
