Features of square tube quenching and tempering production line:
1. Adopt new thyristor water-cooled induction heating medium frequency power control, low power consumption, energy saving and environmental protection, and efficient production.
2. The rectangular square tube quenching and tempering equipment designed by Haishan Electric Furnace adopts V-shaped rollers arranged obliquely in the transmission design to reduce the radial runout.
3. The medium frequency induction heating speed is fast, the surface oxidation is less, the quenching and tempering process is realized in the process of rotary heating, and the steel has good straightness and no bending after quenching and tempering.
4. The square steel pipe after heat treatment has extremely high consistency of hardness, uniformity of microstructure, extremely high toughness and impact strength.
5. The PLC touch screen control system of the rectangular square tube quenching and tempering equipment can record and save all process parameters of the induction hardening and tempering of the workpiece, which is convenient for you to view the historical records in the future.
