This invention discloses a method and apparatus for rust removal from the cross-section of silicon steel laminates, comprising: simultaneously applying an ultrasonic field and a micro-nano bubble flow to the cross-section of the silicon steel laminate, and simultaneously spraying a rust remover onto the cross-section of the silicon steel laminate. The ultrasonic field and the micro-nano bubble flow work together to generate cavitation effect and shear force, which breaks the bonding force between the rust layer on the cross-section of the silicon steel laminate and the silicon steel laminate itself, thus facilitating the removal of the rust layer. Moreover, the physical interaction between the ultrasonic waves and the micro-nano bubbles is mild, with minimal impact on the silicon steel laminate itself. Simultaneously, the rust remover selectively reacts with the rust layer, converting the rust layer into a soluble or easily detachable product, while avoiding reaction with the silicon steel laminate itself. This achieves the removal of the rust layer from the cross-section of the silicon steel laminate without damaging the silicon steel laminate itself or its self-adhesive coating, which is beneficial for ensuring the performance of the silicon steel laminate itself while removing the rust layer from the cross-section. It can directly process silicon steel laminates on the silicon steel laminate production line, which is conducive to realizing continuous online operation.
