Uniform heating of long bar quenching and tempering heat treatment equipment

Hebei FOREVER Electromechanical Co., Ltd. is a high-tech enterprise that has set foot in the research, design, production and technical service of Induction heating equipment earlier in China. In the fields of induction heating, hardening, tempering, annealing and other hot processing, it has rich experience in induction heating theory and production practice. Focus on providing customers with excellent induction heating system solutions and services to achieve customer satisfaction! After using the long bar hardening and tempering equipment, many users will worry about whether the induction heating equipment produced by FOREVER is uniform after hardening and tempering heat treatment? Is there any crack in the treated workpiece? Users can rest assured of this. The following is a detailed description of FOREVER:


The heat treatment equipment produced by FOREVER adopts a closed loop temperature control system. The heating process has strict requirements for temperature. We use the American Leitai two-color thermometer and Siemens S7-300 to form an accurate control system to control the temperature. The temperature difference between the heating furnace and the furnace is controlled within 10 degrees Celsius. Ensure the heating uniformity of the workpiece. The unique feed-forward and feed-forward joint control mode of FOREVER is adopted. The feed-forward system automatically matches the power supply according to the furnace temperature and position. The American Leitai thermometer accurately controls the workpiece temperature and displays the current workpiece temperature in real time. The temperature is heated evenly, and the conveying roller table, the axis of the roller table and the axis of the workpiece form an included angle of 18-20 °;, The workpiece moves forward at a uniform speed while moving autonomously to make the heating more uniform. The roller table between the furnace bodies is made of 304 non-magnetic stainless steel and water-cooled. The feeding system is driven by an independent motor reducer for each shaft and controlled by an independent frequency converter. The output of speed difference is flexibly designed and the running speed is controlled by sections. All the workpieces after tempering and heat treatment are free of cracks.


We adopt the two-color infrared temperature measurement and display of American Leitai:

The temperature measuring device of American Leitai Thermometer adopts non-contact two-color infrared thermometer, which is suitable for measuring temperature in harsh environment with dust and smoke. It is equipped with temperature display and multiple output interfaces for printers or recording instruments. There is temperature display on the external console panel, which is characterized by high accuracy, good reliability and strong resistance to environmental impact.

When the measured temperature exceeds the set value, there is an audible and visual alarm function.

Parameters of two-color infrared thermometer are as follows:

Thermometer model: Raytek MRISASF

Measuring temperature range: 600-1400 ℃

Measurement accuracy: ± 0.75% of full scale

Repetition accuracy: ± 0.3% of full scale

Response time: ≤ 10ms

Ambient temperature: 0-50 ℃

Output: 4-20mA

Power supply: 24VDC, 500mA ± 20%

In the process of development, FOREVER Electromechanical has formed a unique brand competitive advantage: advanced independent research and development strength, advanced production induction heating equipment technology, excellent after-sales service, high-end technical talent team, scientific management structure, and finally formed a market reputation of excellent quality and service. Welcome new and old customers to order induction heating equipment!
