Abstract：Combined with the characteristics of the equipment, product width control measures and width control theory, factors influencing the product width dimension in the 2250mm rolling line have been particularly analyzed. Lateral width elongation abnormal change has been expired by the short stroke control of slab sizing press,the width fluctuation of the coming slab has been removed by width measuring and the necking of the head end and the tail end has been eliminated by the finishing mill tension control and the optimization of the free tension control system of the edger roll. The existed problems in the width control have been effectively solved through the above measures.
