[0002] Tinplate refers to a cold-rolled low-carbon thin steel sheet or strip coated with commercial pure tin on both sides. During the production process of tinplate, a soft melting process is required to quickly heat the tin-plated strip steel to above 232°C (232°C is the melting point of tin) to make its surface bright and form a tin-iron alloy (FeSn2) to improve corrosion resistance and adhesion of the tin layer to the steel base and reduce porosity. For different material specifications, the soft melting parameter control is also different. The soft melting line needs to be adjusted in time. The induction heater is adjusted up and down in time according to the soft melting line to meet the process requirements and ensure product quality. It is urgent to develop it.

[0020] In practical applications, the output current of the inverter cabinet 7 is transmitted to the electrode cylinder 5 through the conductive copper busbar 1 6. There are three groups of arc-shaped copper blocks 1, which are tightly pressed against the electrode cylinder 5 to realize the circulation of current. The conductive copper frame 2 is used to support the arc-shaped copper block 1. The conductive soft connection device 3 ensures the reliable connection between the arc-shaped copper block 1 and the conductive copper frame 2.

The fine-tuning is completed by adjusting the fine-tuning clamping screw 4. When it is necessary to adjust the upper and lower heights of the induction heater, the conductive copper frame 2 moves up and down with it, and the conductive guarantee is completed by the three groups of arc-shaped copper blocks 1. This working process is the positive electrode working process. The negative electrode working process and equipment are the same as the positive electrode, which will not be repeated here (all pressing adjustment work is adjusted when the machine is shut down and not energized).
