Design and Application of Hot-tube Turnover Device of Plug Pipe Mill

Addressing the shortcomings of the manual steel tube turning-over operation such as harsh working conditions,high labor intensity and potential safety hazard,etc.,a hot tube turnover device is designed.Described here in the paper are the design principle and operation effectiveness of the said device.And the problems as staying with the turnover device are identified,and countermeasures worked out.For getting the hot tube automatically turning over,the pneumatic cylinder pushes the rotation-supporting roller upward to hold up the tube,and then drive the tube to rotate.The turnover device is in possession of such advantages as simplified structure,cost effectiveness,easy installation,and sturdiness,resulting in reduction of labor cost,increasing the labor safety factor,and improving the rolling quality of the shell.
