Abstract：The cause for wood grain defect on tinplate strip during power frequency resistance reflow is applied are discussed, and a new technique for eliminating the defect is presented. Variable frequency resistance reflow can eliminate wood grain defect by adjusting reflow power supply frequency from 50Hz to 200Hz. In different process conditions, the minimum power supply frequency for eliminating the defect varies. The application of variable frequency resistance reflow in 400m/min electrotinplate production line is introduced in detail. Comparing with the currently used combination reflow of power frequency resistance reflow and high frequency induction reflow, the new technique increases not only power supply efficiency, but also scratch resistance of tinplate. It is especially suitable for high speed electrotinplate production line.
