Feeding
Induction Heating
Water Cooling
Functions:
1. Reduces the hardness of steel pipes, improves plasticity, and facilitates machining and cold deformation.
2. Creates a fine-grained and homogeneous steel structure to enhance steel performance and prepare it for
heat treatment.
3. Removes residual internal stress in the steel to prevent deformation and cracking.
Features:
No need pre-heating. Comparing traditional black annealing furnace, this induction heating furnace only takes 10-15 minutes to reach the exact temperature.
No need re-straightening. Using rotary tube delivering structure, there is only tiny deformation after heat treatment.
Automatic uploading tubes, with strict docking of front and rear tube's end.
Fully automatic running, saving labor cost.
