Description of process and working process of oil drill pipe quenching and tempering production line :

1 , the heat treatment process: steel material placed on the crane gantry by loose bundle → upper feeder feeding → Frequency feed roller steel pipe is fed forward → induction heating furnace for hardening (high temperature) , was heated to 950 ℃ IR measurement Temperature feedback constitutes closed-loop control and adjustment , which automatically adjusts the power of the induction heating furnace → spray quenching → lift the pipe by the turning machine and place it on the residual water drain device → lift the tube by the turning machine and place it on induction heating On the tempering roller table of the furnace → enter the tempering induction heating furnace (heating) to heat to 450 ~ 760 ℃ infrared temperature measurement and feedback to form a closed-loop control to adjust the induction heating furnace power → turning machine → chain two-way cooling bed → turning machine → Discharging . 

2 , the technical parameters selection drill pipe to quenching and tempering production line summary

Oil quenching and tempering production line drill pipe production line IF power control features:

● Parallel resonance design, phase shift power adjustment, the equipment is mature and stable; it has more advantages in the high power range above 3000KW .

●DSP control, extremely fast capture phase lock start, meeting frequent start and stop, 100% success rate .

● Frequency conversion and variable load self-adaptation, frequency adaptation range 200-10000Hz, automatic matching of induction heating furnace  replacement, no manual adjustment is required.

● T2 red copper copper bars are used in the cabinet , which are sandblasted and passivated; low leakage inductance, anti-oxidation, and effectively reduce line loss.

● Full touch screen control, pure digital setting, complete process record and strict level authority. The main parameters can be restored to factory settings with one key.

●The equipment has self-protection function (over current, over pressure, water pressure, lack of phase, under voltage, overload), and the equipment has self-diagnosis function in case of situation.

Configuration composition and characteristics of oil drill pipe quenching and tempering production line:
