Seamless steel tube straightening process
1. The seamless steel tube enters the roller table at the entrance of the leveler from the upstream roller table.
2. When the head of the seamless steel tube is sensed by the sensor element in the middle of the entrance roller table, the roller table will decelerate.
3. When the head of the seamless steel tube is sensed by the sensor element at the end of the entrance roller table, the first stage of the entrance roller table falls, and the closing delay of the inlet quick-opening cylinder starts to count.
4. When the pipe head enters the middle position of the inlet straightening roller, the inlet quick opening cylinder is closed, the seamless steel tube is bitten in, and at the same time the second roller table of the inlet falls.
5. Through the setting of the delay time of the quick-opening cylinder, when the pipe head enters the middle position of the intermediate roll and the exit roll, the quick-opening cylinders of the intermediate roll and the exit roll are closed successively, and the seamless steel tube enters the straightening process.
6. When the tube tail leaves the sensor element in the middle of the entrance roller, the first section of the entrance roller rises.
7. When the tube tail leaves the sensor element at the end of the inlet roller table, the second section of the inlet roller table rises. At the same time, through the setting of the quick-open cylinder delay, when the tube tail reaches the middle position of the inlet roller, the middle roller and the outlet roller, The quick-opening cylinders of the inlet roller, the middle roller and the outlet roller are opened successively.
8. The outlet roller table rises, and the seamless steel tube is transported to the baffle at the end of the outlet roller table.
9. The exit roller table is lowered, the side door of the channel is opened, and the seamless steel tube rolls onto the L-shaped splicing hook by gravity.
10. When the receiving hook falls, the seamless steel tube rolls onto the soot-blowing stand, and the iron oxide scale on the inner surface of the seamless steel tube is purged.
