drill collar quenching tempering line

Drill collars are typically solid round bars of 4145 carbon steel. The bars are then quenched and tempered in a heat treatment process to attain the required metallic properties and hardness for drilling. Once heat treatment is complete, a hole is machined through the bar in a coring/honing process known as trepanning. After the trepanning is complete, the ends are threaded which makes the connections. The end result is a drill collar. Temperature regulation is critical to achieve the correct heat treat properties. We have a unique PID control loop handshake that passes off the temperature regulation from one sensor to another within a coil to maintain temperatures of +/- 5 degree C.

Normal configuration

●  Mediate frequency solid power supply
●  Capacitor 
●  Induction heating coils
●  Feeding and discharging transmission device 
●  Spray cooling device
●  Temperature measuring equipment

Full automatic control: the system need to add PLC programmable controller, man-machine interface or industrial control computer system and industrial control configuration software and various sensors, etc.
