Abstract

PURPOSE:To perform high speed and high precise plating and to suppress inconveniences of the working due to splashing, by surrounding a metal band rising section between a plating bath surface and a gas wiping apparatus by a hot region. CONSTITUTION:In the continuous hot dipping, the metal rising section 2A situated between the bath surface of a plating bath 1 and the gas wiping nozzles 14 is surrounded by the heat insulation chamber 15. The waste gas of a reducing furnace 10 is introduced via a blower 16 and a conduit 16A into the heat insulation chamber 15. Thus, while the steel band 15 is passed through the heat insulation chamber 15 to reach the gas wiping nozzles 14, it is by the reducing waste gas in the chamber 15 kept at a temperature that suppresses reduction of flowability of the hot dipping metal. Accordingly, when the steel band has passed through the heat insulation chamber 15, the excess of the hot dipping metal flows down sufficiently and naturally, and therefore the amount of metal to be removed by the gas wiping nozzles 14 can be reduced.
