The working principle of the automatic opening and closing induction heating coil is based on the principle of electromagnetic induction heating system. When an alternating current passes through an induction coil, a changing magnetic field is generated around the coil. When this magnetic field passes through a conductive workpiece, it will generate induced currents inside the workpiece, namely eddy currents. When eddy currents flow inside metal, due to the resistance of the metal, electrical energy is converted into thermal energy, thereby heating the workpiece. The automatic opening and closing design allows the coil to automatically open and close during the heating process, reducing energy loss when heating is not required and quickly wrapping the workpiece when heating is needed, improving heating efficiency and operational convenience
The automatic opening and closing induction heating coil is an indispensable component in the induction heating system, which is an advanced induction heating technology that heats metal workpieces through the principle of electromagnetic induction. The design feature of this coil is that it can automatically open and close, which greatly expands the application range of electromagnetic heating coils, especially when heating large workpieces or joints under special working conditions, making the operation more convenient.
The automatic opening and closing induction heating coil can be used for heating, softening, extruding and connecting steel bar joints, preheating oversized workpieces of large tanks, and tempering treatment of welded joints after welding. In addition, this coil can also be designed to automatically open and close radially to improve automation and safety performance.
When designing and using automatic opening and closing induction heating coils, it is necessary to consider the material, size, power frequency, and control system of the coil to ensure heating efficiency and workpiece heating quality.
