 bar quenching and tempering process and working process description:

1. Heat treatment process: the steel pipes are placed on the loading platform by the overhead crane for bulk bundling → feeding machine feeding → frequency conversion feeding roller table to transport the steel pipe forward → quenching medium frequency induction heating inductor (low temperature) furnace, (high temperature) furnace Heating to 950 ℃ infrared temperature measurement and feedback to form a closed-loop control to adjust the power of the intermediate frequency induction heating furnace → spray quenching → lift the tube by the turning machine and place it on the residual water drain device in the tube → lift the tube by the turning machine On the tempering roller table→(low temperature) tempering induction heating furnace→(high temperature) tempering medium frequency induction heating sensor (heating) heated to 450～760℃, infrared temperature measurement and feedback form closed-loop control to adjust the medium frequency induction heating furnace power→turn Feeding machine → chain two-way cooling bed → turning machine → discharging . 

2. Summary of technical parameter selection for bar quenching and tempering production line

The performance characteristics of the bar quenching and tempering production line :

1. The quenching and tempering production line has a simple structure and reliable performance, which can meet different heat treatment processing requirements, and the equipment is simple to operate and easy to maintain;

2. The processed products have beautiful appearance and strong production capacity. Using the principle of electromagnetic induction heating , the quality of processed products is excellent, the heating is uniform, and the temperature difference between the core and the surface is small;

3. The quenching and tempering production line has advanced control systems and precise control. The fully automatic control system provides manual control, feed control, constant power control and other operation modes to choose from. The automatic monitoring system can understand the operating status of the equipment in real time, which is conducive to the best performance of the equipment;

4. Optimized structure design, long service life, non-contact heating of the workpiece by the induction coil of the quenching and tempering production line , no friction, high reliability, and prolongs the service life of the equipment;

5. The equipment of quenching and tempering production line has low operating cost, split structure design, reducing equipment occupation of workshop space, reasonable and standardized layout of equipment components, simple and convenient maintenance, and lower operating cost.

What is the general configuration of the quenching and tempering production line ?

The user needs are different, and the configuration is different. The basic configuration includes: induction heating system, storage rack (feeding rack and discharge rack), induction heating power supply ( IGBT intermediate frequency power supply or KGPS intermediate frequency power supply ), PLC console, etc. Optional: infrared thermometer, power transformer, cooling tower, etc. These can allow professional manufacturers of bar quenching and tempering production lines to support you, and they will provide detailed design plans according to your needs.
