1. Eliminate stress and normal tractor high pressure tubes are cold-headed expansion (20 steels), and also use induction normal fire to restore normal.
1. Eliminate stress and normal tractor high pressure tubes are cold-headed expansion (20 steels), and also use induction normal fire to restore normal.
2. Penetrate the quenching and tempering well engineering pipe, the outer diameter of 60 ~ ∅ 410, between the wall thickness is 5 ~ 16mm, and the 1000 Hz intermediate frequency power supply has been applied to penetrate the heat quenching, and the fire (600 ~ 700 ° C) is also carried out with an intermediate frequency power supply. Screw blanks have also successfully heated.
3. Apply induction heating to reduce the diameter of the tube cold cutting tube in the cold state, the amount is small, and there is also an annealing, pickling, and complex process. The induction heating pull tube can be reduced by 1.5 times, and the annealing, pickling, etc. will be canceled.
