Round steel heat treatment production line

A. Applicable scope of intelligent round steel heat treatment production line

The intelligent round steel heat treatment production line is suitable for the quenching and tempering treatment of round steel, round steel, bars, pipes, rods and other workpieces with a diameter of 20-300mm.

B. Intelligent round steel heat treatment production line process flow

Manual feeding → roller conveyor → quenching heating → water spray quenching → roller conveyor → tempering heating and heat preservation → tempering cooling → roller conveyor → chain cooling bed → receiving rack

C. Composition of intelligent round steel heat treatment production line

1. Feeding mechanism and discharging mechanism

2. Conveying roller table (the workpiece is being fed at a constant speed while rotating, and the operation is stable, the speed is adjustable, and the heating is more uniform)

3. Quenching induction heating system

4. Quenching spray system

5. Tempering induction heating system

6. The PLC master console (including frequency conversion speed control and temperature control, Huayan industrial computer, remote start, etc.) is to directly operate the entire quenching and tempering equipment on the central console, and only one person can operate the round steel quenching Tempering production line saves labor and costs.

7. Quenching intermediate frequency power supply KGPS

8. Tempered intermediate frequency power supply KGPS

D. Performance characteristics of intelligent round steel heat treatment production line

Features of intelligent round steel heat treatment production line:

1. The axis of the pipeline and the axis of the workpiece form an angle of 18-21°. The workpiece moves forward at a constant speed while autotransmitting, so that the heating is more uniform. The roller table between the furnace body is made of 304 non-magnetic stainless steel and water-cooled.

2. The ratio of the inner diameter of the inductor coil to the outer diameter of the blank is within a reasonable range, which is designed according to the process parameters provided by the user.

3. The sensor base adopts aluminum-plastic base, which is anti-corrosion and durable. The heating sensor adopts a quick-change structure, which is convenient for maintenance and replacement.

4. The conveying roller of the intelligent round steel heat treatment production line adopts a hollow water-cooled rotating roller, which will not cause the bearing to be overheated and damaged during induction heating. The intelligent round steel heat treatment production line automatically refuels the bearing, which can extend the service life of the bearing . Ensure its long-term stable operation.

5. The feeding method of the intelligent round steel heat treatment production line adopts the inclined roller self-rotating feeding, which infinitely guarantees the uniformity of heating.

6. The whole working process of the intelligent round steel heat treatment production line realizes automatic control of feeding, heating, and receiving processes. Frequency conversion speed adjustable oblique roller drive, in order to ensure that the workpiece is not deformed during the annealing process, each intelligent round steel heat treatment production line is equipped with a V-shaped roller at a certain angle with the axis of the bed, and the V-shaped roller must have sufficient strength , Rigidity, and abrasion resistance

7. The transmission device of the intelligent round steel heat treatment production line adopts the stepless speed control inverter produced by Japan’s Fukagawa Company. The speed can be preset by number, which is convenient to adjust the speed of entering the sensor. The accuracy of the advancement speed and rotation speed of the workpiece meets the requirements of the heat treatment process, the operation is stable and reliable, and the speed of the workpiece is accurately controlled.
