Description

Technical Field

[0001] The present application relates to the technical field of enameled wire production, and in particular to an enameled wire magnetic induction heating device. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked for multiple times. During the production and processing of enameled wire, the copper wire needs to be annealed. After annealing, the internal stress and prestress of the copper wire are well eliminated. The softened copper wire can be processed in the next step. After annealing, the residual temperature of the copper wire needs to be cooled to avoid oxidation of the copper wire. After water cooling, the water stains remaining on the surface of the copper wire need to be removed. After removing the water stains on the surface of the copper wire, wax oil needs to be applied to the surface of the copper wire to help preserve the copper wire and avoid oxidation of the outer wall of the copper wire.

Therefore, the heat utilization rate of the entire drying device is not high, which indirectly reduces the heating efficiency of the copper wire. Utility Model Content
