Abstract

The invention discloses a method and a system for induction heating of hot-rolling mill rollers for lithium battery pole pieces. The method mainly comprises steps as follows: one medium-frequency or high-frequency AC (alternating current) induction heating coil is additionally mounted on the surface of each pole piece roller, each pole piece roller is loaded with an alternating electromagnetic field by the aid of the corresponding induction heating coil, and same-frequency induction currents are produced on superficial layers of corresponding parts of each pole piece roller and the corresponding induction heating coil, so that the corresponding part of each pole piece roller is heated to the required heating condition temperature; a non-contact infrared temperature measuring probe is mounted in the range where each pole piece roller rotates out of the corresponding induction heating coil, and each probe is used for measuring the heating temperature of the corresponding pole piece roller. The method and the system for induction heating of the hot-rolling mill rollers for the lithium battery pole pieces can overcome defects of low heating efficiency, high energy consumption and the like in the prior art and have the advantages of high heating efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to a method and system for inductively heating rolls of a lithium battery pole piece hot rolling mill. Background technique [0002] The heating method adopted by the pole piece hot rolling mill rolls prevailing in the current industry is as follows: [0003] ⑴Place heating resistors in the rolls and directly energize and heat them; ⑵Heat the heat-conducting oil to the rated temperature by the oil temperature machine, and pass the heat-conducting oil into the rolls through the pipeline to heat the rolls. [0004] These methods of heating the rolls all have complex equipment structures, and require special design for the rolls to be connected to a heating power supply or a pipeline for heat-conducting oil. Moreover, these methods all belong to the overall heating of the roll, the heating process is long, and a large amount of heat energy is radiated to the space e...
