Main technical parameters of round steel bar material 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 over & Oslash; 20 – & Oslash; 120mm.
3. Conveying roller table: the axis of the roller table and the axis of the workpiece form an included angle of 18-21-deg.; the workpiece rotates while moving forward at a constant speed to make the heating more uniform. The roller table between furnace bodies adopts 304 non-magnetic stainless steel and water-cooled.
4. Roller table grouping: the feed group, inductor group and discharge group are controlled independently, which is conducive to continuous heating without gaps between workpieces.
5. Temperature closed-loop control: both quenching and tempering are controlled by American raytime infrared thermometer closed-loop control system, with precise temperature control.
6. Industrial computer system: real-time display of the working parameter status, workpiece parameter memory, storage, printing, fault display, alarm and other functions.
7. Energy conversion: adopt quenching + tempering mode, power consumption per ton is 280-320 degrees.
8. The human-machine interface PLC full-automatic intelligent control system, the production of “one key start” is worry free.
Working process of mechanical system of round steel bar material tempering production line:
Crane; storage platform; automatic renewal mechanism; feeding roller table system; quenching induction heating system; infrared temperature measuring device; discharging roller table; spray quenching system; quenching completion; tempering conveying system; tempering induction heating system; infrared temperature measuring device; discharging roller table; cooling mechanism; receiving rack.
The advantages of round steel bar heat treatment furnace are as follows:
1. The new IGBT air-cooled induction heating power supply control is adopted, with low power consumption, energy saving and environmental protection, and high production efficiency.
2. In the drive design of YUANTUO’s round steel bar material tempering production line, V-shaped roll with inclined arrangement is used to reduce the run out in small diameter direction.
3. The heating speed is fast, the surface oxidation is less, the quenching and tempering process is realized in the rotary heating process, and the steel straightness is good and does not bend after quenching and tempering.
4. After heat treatment, the workpiece has high hardness uniformity, microstructure uniformity, high toughness and impact strength.
5. PLC touch screen control system can record and save all process parameters of induction hardening and tempering of workpieces, which is convenient for you to view the history in the future.
