Bar quenching and tempering production line

To

Main technical parameters of bar quenching and tempering production line:

1. Power supply system: quenching power supply + tempering power supply

2. The output per hour is 0.5-3.5 tons, and the scope of application is above ø20-ø120mm.

3. Conveying roller table: The axis of the roller table and the axis of the workpiece form an angle of 18-21°. The workpiece rotates while moving forward at a constant speed to make the heating more uniform. The roller table between the furnace bodies is made of 304 non-magnetic stainless steel and water-cooled.

4. Roller table grouping: the feeding group, the sensor group and the discharging group are independently controlled, which is conducive to continuous heating without causing a gap between the workpieces.

5. Temperature closed-loop control: both quenching and tempering adopt the American Leitai infrared thermometer closed-loop control system to accurately control the temperature.

6. Industrial computer system of quenching and tempering heat treatment equipment: real-time display of the status of working parameters at the time, and functions of workpiece parameter memory, storage, printing, fault display, alarm and so on.

7. Energy conversion: using quenching + tempering method, power consumption per ton is 280-320 degrees.

8. Human-machine interface PLC automatic intelligent control system, “one-key start” production worry-free.

Advantages of the bar quenching and tempering production line:

1. It adopts new IGBT air-cooled induction heating power supply control, low power consumption, energy saving and environmental protection, and high production efficiency.

2. The bar material quenching and tempering production line designed by Yuantuo adopts V-shaped rolls arranged diagonally in the transmission design to reduce radial runout.

3. Fast heating speed, less surface oxidation, quenching and tempering process in the rotating heating process, and the steel has good straightness and no bending after quenching and tempering.

4. After the heat treatment, the workpiece has the consistency of extremely high hardness, uniformity of microstructure, extremely high toughness and impact strength.

5. The PLC touch screen control system can record and save all the process parameters of induction hardening and tempering of the workpiece, which is convenient for you to view the historical records in the future.
