FIELD: coating of metal materials. SUBSTANCE: material without changing direction is supplied vertically through reservoir receiving molten coating material and having, on the side of bottom, passage channel enclosed with electric field, in zone of channel opening, in melt, electromagnetic force arises whose value is equal to, or higher than, the force acting on product from channel opening area proportional to metal static pressure and has direction opposite to vector direction of metal static pressure and at which dwell of strip in melt is regulated irrespective of strip speed of throughput. Reservoir for application of coating, which receives molten coating material has reservoir for preliminary melting. In this case, the volume of reservoir for coating application is several times as low as that of reservoir for preliminary melting. Level of melt in reservoir for coating application may be regulated by adding and/or emptying of reservoir of preliminary melting. EFFECT: higher efficiency. |
