The annealing is a common heat treatment process for metal workpiece processing, and can be divided into full annealing, isothermal annealing, diffusion annealing, spheroidizing annealing, destress annealing, recrystallization annealing and the like according to different Annealing furnace for steel tube.
The purpose of annealing:
1. the hardness of the steel is reduced, the cutting process is facilitated, the HB is 160-230, and the HB is most suitable for cutting and processing, and the HB is just right after the annealing;
2. the residual stress is eliminated, the size of the steel piece is stabilized and the deformation and the cracking are prevented;
3. the crystal grains are refined, the structure is improved, and the mechanical property of the steel is improved;
4. Prepare for final heat treatment (quenching and tempering).
The manufacturer of the electric induction heating equipment of Huotuo in Hebei is a special heat treatment furnace for heat treatment, and the high-precision temperature measuring instrument is adopted for the remote-to-large electromechanical induction heating equipment, and the closed-loop temperature control system is arranged, so that the system can automatically adjust the power, and the heating quality is guaranteed.
