16-32 sucker rod hardening and tempering line
Sucker rod is a high-strength metal rod used in the oil field to raise oil. Due to the high strength of the work, there is a very strict requirement for its own characteristics, and the corresponding quenching part is also a very important part. The sucker rod induction hardening and tempering equipment is mainly composed of two parts, including the induction heating part and mechanical part. Induction heating surface hardening has the advantages of good surface quality, low brittleness, difficult to oxidize decarburization, and small deformation. Therefore, induction heating has been widely used in this industry.
Though hardening and tempering treatment is actually quenching and high temperature tempering composite heat treatment process.Traditional treatment is using resistance furnace, but it has disadvantages of low productivity and bad quality. According to the characteristics of round bar, our company has specially designed the intermediate frequency hardening and tempering equipment successfully applied to the oil rod, hydraulic pipe and other quenching and tempering heat treatment, the quality is stable, the quality of the material is very good. The production efficiency increased by 2 to 3 times, and achieved significant economic benefits.
Sucker rod induction hardening and tempering equipment is using intermediate frequency induction quenching device, IF induction rod tempering device, club head induction tempering device. Its characteristics are: head and rod body can get the same heating temperature and hardness. The overall material is stepless speed control, easy to operate.
The complete induction hardening and tempering equipment is mainly composed of mechanical conveying device, intermediate frequency quenching heating equipment, intermediate frequency tempering heating equipment, end tempering heating equipment, closed cooling system, infrared temperature measuring device, quenching cooling device and main control table and so on.
The mechanical feeding device comprises storage platform, turning device, roller feeding device, discharge device.
The conveying method adopts the inclined shaft roller, and each roller has one step frequency conversion motor, which can guarantee the workpiece rotate by itself and go forward. And the running speed is adjustable. This can ensure uniform temperature and reduce the deformation, there is a certain straightening effect.
For the quenching part of the spray, quenching process will cause more impurities,which will block the sprayer, we also specially designed from the self-cleaning filter to ensure the purity of water.
