Abstract: A start-tyPe flying shear controlled by the micro-computer control system can complete the works of cut head and tail, cut-to-length and cut-to-average length for high speed continuous hot rod mill.Based on the Principle, it can descride the shearing errors and the method of improving accuracy.The hardware figures and softwares block diagrams of the system are Presented in this Paper.
It has been proved by the industrial scale experiment that the shearing eorror was decreased greatly.
