Abstract:Combined with the weighing and measuring practice of SCR copper rod continuous casting and rolling production, the factors influencing the weighing and measuring pound difference and weighing failure of SCR copper rod continuous casting and rolling production line are studied, and control method of the weighing system of production line is probed in this paper. By installing the on-line weighing device in the coiling and packing process and designing the on-line weighing system, the accuracy of weighing measurement is improved and the complaint of weight difference is reduced, which lays a good foundation for improving the quality and efficiency of SCR continuous casting and rolling production line.
