Abstract

PURPOSE:To produce one-side plated steel plates by disposing a positive electrode near the plating surface of the steel plate and a negative electrode on the non-plating surface side, letting hydrocarbon gas burn imperfectly while applying voltage between both electrodes to let soot deposit on the non-plating surface and introducing the steel plate into a hot dipping bath. CONSTITUTION:A steel hoop 6 having been cold rolled is introduced into an oxidizing furnace 7, where deposits such as rolling oils are burnt away. Next, it is put into a reducing furnace 8 of the atmosphere of H2; 10%, N2; 90% to reduce the oxide film on the surfaces of the steel hoop 6. The steel plate 6 is then put into a masking chamber 9, where a DC voltage of 500V or higher is applied between the positive electrode 2 disposed by leaving a spacing of 1 to 50 mm on one side and the burner 3 being a negative electrode for causing acetylene gas or the like to burn imperfectly. Soot produced through incomplete combustion is evenly deposited on the steel hoop surface on the negative electrode side. This steel hoop is then introduced into a hot dipping bath 11 such as of Zn. The surface having been deposited with soot is not plated, thus the one-side plated steel hoop is readily obtained.
