Adjustment Method for Reducing Operating Noise of Slitting Machine

The problem of excessive noise as caused by the steel plate jumping and curling during in the process of the longitudinal slitting of the steel plate for the weld pipe is solved by means of taken such technical measures as installing the press roll device，modifying the structure of the separating plate，and systematically optimizing the overall process form，etc. And moreover due to the said technical measures，the routine maintenance frequency is obviously reduced，the working safety level for the employees is enhanced，and the labor intensity is lowered down. The actual application effectiveness of the said new process is significant，showing that the unstable straining state of the plate after de-coiled is eliminated. Meanwhile the process operation procedures are specified，and the required noise level of the slitting machine beyond 2 m，i.e.，below 60 dB is satisfied.
