Many metallurgical equipment faults are caused by the compressibility of hydraulic oil.The practical case of solving the problem of receiving and buffering cylinder fault is combined in the delivery roller table of the billet elevator of high speed wire mill.Through theoretical calculations,the compressibility of hydraulic oil in this case is quantitatively analyzed.The results indicate that in long and large diameter pipelines,the compression length of hydraulic oil under high pressure and dynamic conditions far exceeds the working stroke of the cylinder itself,so it causes fault.Aiming at the cause of the fault,corresponding hydraulic and process response methods have been proposed.
