ABSTRACT: A specially designed experimental platform based on the principle of electromagnetic hydromechanics to remove zinc drosses formed on the surface of molten zinc in zinc pot of hot-dip galvanizing line was presented in this work. The main components of the platform were electromagnetic field generator, zinc pot, cooling water system, power control cabinet, and supporting platform. The electromagnetic field generator was installed on the top of zinc pot. Three experiments were conducted when the loading current, frequency, and the distance between the bottom of the electromagnetic field generator and the surface of molten zinc were 300 A, 20 Hz, and 180 mm, respectively. The results showed that the relative aggregation degrees of zinc drosses were 26.4, 27.1, and 25.9. It manifested that zinc drosses can be effectively aggregated by an external electromagnetic field to a desired location so as to remove from the surface of molten zinc in zinc pot.
