<p>PURPOSE:To provide a plated material treating device capable of rapidly heating plated materials, removing plating metal with high efficiency from these plated materials, suppressing generation of harmful materials such as zinc oxide, recovering this plating metal with high efficiency and obtaining iron having good purity. CONSTITUTION:This plated material treating device has a vessel body 1 which is provided with a plated material charge port 5 in the upper part, is provided with a gas introducing pipe 8 for introducing a reducing gas or inert gas and an iron scrap take-out port 10 in the bottom and can be reduced in pressure, a fluidized sand circulating means 2 which is disposed at this vessel body 1 and supplies the fluidized sand (s) flowing out of the vessel body 1 again to the inside of the vessel body 1, a fluidized sand heating means 3 which is disposed at this fluidized sand circulating means 2 and heats the fluidized sand (s) and a metal capturing means 4 which is disposed at the vessel body 1 and captures the evaporated plating metal. As a result, the generation of the harmful materials such as zinc oxide is suppressed.</p> |
