The Forever steel bar induction hardening and tempering machine is a type of equipment produced by Hebei Forever Electromechanical Equipment Manufacturing Co., Ltd. for steel rod heat treatment.
This device utilizes the principle of medium frequency electromagnetic induction heating. When an alternating current passes through the induction coil, an alternating electromagnetic field is generated inside the coil, which cuts the steel rod and induces an alternating current inside the steel rod. Due to the skin effect, the current is mainly concentrated on the surface of the steel rod, causing the surface temperature to rise. After reaching the quenching temperature, water spray cooling or other cooling methods are used to achieve the quenching effect. Tempering is the process of induction heating the steel rod again after quenching, keeping it at an appropriate temperature for a period of time to release internal stress and improve toughness.
Advantages and Characteristics steel bar induction hardening and tempering furnace
Efficient and energy-saving: Electromagnetic induction heating is used for heating, which is 2-3 times more efficient than resistance furnaces. After quenching, the power consumption per ton is less than or equal to 500 degrees, far lower than resistance heating.
Excellent quality: After quenching, the metallographic structure is finer, the mechanical strength is 10-15% higher than that of resistance furnace treatment, the product consistency is good, and the surface hardness and toughness can be flexibly adjusted according to process requirements.
High degree of automation: Online continuous heating and quenching, only two people can operate the complete set of equipment, from steel bar feeding, heating to cooling, the whole process is automatically controlled, greatly reducing manual operation intervention, suitable for high-intensity continuous production needs.
Environmental Protection and Safety: No pollution to the environment, stable equipment operation, safe operation, modular design of induction coils for easy maintenance, closed-loop cooling system to reduce the risk of scale blockage, extend Long bar induction heat treatment machine operation life, and reduce maintenance frequency.
