It is usually made of cold-rolled steel plates and has certain dimensions and wall thicknesses, which determine the volume of the liquid storage device. The working principle of the induction heating device is mainly based on electromagnetic induction and the current thermal effect. When an alternating current passes through the induction coil, an alternating magnetic field will be generated around it. This alternating magnetic field acts on the object to be heated (usually metal), thereby generating an induced current, that is, eddy current, inside the object. When the eddy current flows inside the object to be heated, due to the existence of resistance, a large amount of heat energy will be generated. When processing the liquid storage cylinder body, it is necessary to heat the steel pipe. During the use of the existing heating equipment, usually, the staff holds the heating equipment to heat the steel pipe, with low efficiency and unable to automatically heat the steel pipe.

[0037] During the actual operation process, when this device is in use, first, an external power supply device supplies power to the high-frequency power supply 223, enabling the high-frequency power supply 223 to supply power to the heating coil 222. Then, the steel pipe to be heated is placed inside the fixed sleeve 214, and the middle and rear parts of the steel pipe are positioned inside the fixed sleeve 214. According to the size of the steel pipe, the first cylinder 215 drives the first clamping plate 219 to move, making the inner side of the first clamping plate 219 contact the outer periphery of the steel pipe, thus fixing the steel pipe.
