PURPOSE:To carry out one-side plating with good productivity by bringing a steel strip into contact with a predetermined belt while placing the portion below the contact points under the surface of a hot dipping bath. CONSTITUTION:Steel strip 1 pretreated by gas purification, flux treatment, etc. is passed through hot dipping bath 4 by means of belt 3 guided by a plurality of guide rolls 2 to carry out one-side plating. At this time, contact points 5 of belt 3 and strip 1 are placed over surface 6 of bath 4. In order to ensure close contact of strip 1 guided by belt 3 with belt 3 so that a molten metal is prevented from penetrating between belt 3 and strip 1, strip 1 is applied with enough tension or brought into close contact with belt 3 by means of support rolls 7. |
