Abstract
This experimental study was conducted on the equipment of pipe-rolling plant-140 with an automatic mill in order to give a qualitative and quantitative evaluation of the parameters which define the pipe wall sizing process in reeling mills. During investigation values of the power parameters of the process were recorded for different sizing routes. Conclusions about the special features of the wall sizing process and feasibility of extension of the reeling mill process capabilities were formulated.
Highlights
The reeling mill of pipe-rolling plant-140 is a non-reversing screw rolling mill with individual drives for each of its three rolls (Figure 1)
To evaluate dynamics of the current loads of the electric drives of the drivelines of the reeling mill work rolls, the sampling rate for the recorded signal was 0.02-0.04 s, which corresponds to the frequency of 25-50 Hz
To evaluate dynamics of the processes running in the drivelines of the sizing mill work stands, the sampling rate for the main power parameters was equal to 0.016 s (62.5 Hz)
Summary
The reeling mill of pipe-rolling plant-140 is a non-reversing screw rolling mill with individual drives for each of its three rolls (Figure 1). To evaluate dynamics of the current loads of the electric drives of the drivelines of the reeling mill work rolls, the sampling rate for the recorded signal was 0.02-0.04 s, which corresponds to the frequency of 25-50 Hz. The original system for measurement and recording of load parameters, which was developed in Ural Federal University, is a wireless data transfer system.
