What is the advantage of a famous supplier’s screw rod hardening and tempering furnace?
The process of metal heat treatment should not cause pollution to the environment. Induction heating technology makes change and progress in this industry every day. Yuantuo is very professional in the field of metal induction heat treatment as we have already much practical experience in the field of design and production of induction heat treating furnace of bars, pipes and plate. The function of PLC console of hardening and tempering furnace is make operator can operate the system directly on the remote console. The worker only need to start the system and select the corresponding recipe and then the system will run as per setting parameters. In order to meet the heat treatment process requirement, we adopts continuous heating way and achieve temperature adjustment through the power adjustment. The mechanical transmission part is driven by a speed regulating motor, which may adjust the running speed and power of the workpiece at will.
The induction heating power supply control system of medium frequency hardening and tempering furnace adopts our company’s unique design control chip, and is currently an advanced control mode. The series resonant power supply has high power factor (> 0.95), low harmonic content, high electric efficiency, simple rectification control. And the success rate of the screw rod hardening and tempering furnace is more than 99% (there is no starting difficulty in the working condition). The 12 pulse medium frequency power supply has little high harmonics, the rectifier output voltage is constant and the waveform is good. Therefore, the operation efficiency of the medium frequency hardening and tempering furnace is high, which can save 10 to 20% electric energy, and the energy saving effect is obvious. The series resonance is designed to control the digitalization of the electronic control, and all trigger signals are transmitted through the optocoupler.
Control of holding temperature
For induction heating equipment, thermal insulation is relatively easy, in the process of holding temperature, the distribution of temperature on the workpiece generally continue to change, the heat dissipation of the workpiece also changed. In order to get accurate temperature, we adopts closed-loop temperature control.
Control of cooling
Because the power supply is adjustable, the screw rod hardening and tempering furnace can control the cooling speed of the workpiece accurately, but when the cooling speed is higher than the natural cooling speed, it can only take external forced cooling, such as air cooling or even water cooling.
