Abstract

PURPOSE:To correct pinholes in a short time and produce a striplike material of good corrosion resistance by successively applying fused zinc plating and zinc electroplating on the surface of the striplike metal. CONSTITUTION:A striplike metal 1 is introduced via tension bridles 4 and an inlet side loop car 5 into an annealing furnace 6, whereby it is annealed. Thence, while it is put on a sink roller 8, it is dipped in a zinc hot dipping bath 7 and the molten zinc is solidified in a cooling tower 9. At this time, pinholes are produced. Next, the metal 1 formed with a fused zinc plating layer is dipped in a zinc electroplating bath 10, so that an electroplating layer is formed on the bottoms of the pinholes. The surface of the metal 1 formed with the electroplating layer is screwed down with a skin pass mill 11, and the surface is smoothed with a post treatment device 12. Thence, the metal 1 is taken up on a tension reel 14 via an outlet side loop car 13.
