steel bar induction hardening and tempering furnace is a device that converts electrical energy into thermal energy through electromagnetic induction principle, mainly used for heating and tempering metal workpieces such as round steel. This device heats the workpiece locally through induced current, achieving heat treatment processes such as surface quenching, local annealing, or tempering.
working principle:
The working principle of the steel bar hardening and tempering induction furnace is to use electromagnetic induction phenomenon to place the workpiece in an induction coil with alternating medium frequency current. Although the workpiece is not in direct contact with the induction coil, the magnetic field generated by the energized coil will generate eddy currents inside the workpiece, causing it to heat up and raise its temperature. By adjusting the frequency and current strength, the heating speed and temperature of the workpiece can be controlled.

Characteristics of steel bar induction heat treatment production line:
Fast heating speed: The heating speed of the steel bar hardening and tempering furnace is very fast, which can heat the workpiece to the required temperature in a short time, thereby improving production efficiency
Uniform heating: As induction heating generates heat within the workpiece itself, the heating is very uniform, with a small temperature difference between the core and surface, which is beneficial for ensuring the quality of the workpiece.
Digital control: Modern medium frequency induction steel bar hardening and tempering induction furnace usually adopts PLC intelligent control, which can achieve precise control of temperature, speed and other parameters, improve product quality and qualification rate.
Energy saving and environmental protection: The medium frequency steel bar hardening and tempering induction furnace is more energy-efficient and environmentally friendly than traditional coal-fired furnaces, gas furnaces, etc., and meets current environmental protection requirements.
High degree of automation: This equipment can achieve automated production, reduce manual operations, and lower labor intensity.
