Hot dipping apparatus

摘要

A heating furnace (2) heats a workpiece to be plated. An ingot preheating furnace (8) encloses an ingot carrying device (7) that carries ingots (6) to a place near a melting furnace (3) that melts the ingots (6) of a plating material, contains the molten plating material in which a workpiece to be plated is immersed. The ingot preheating furnace (8) preheats the ingots (6) supported by the ingot carrying device (7) at a temperature below the melting point of the ingots (6) by an exhaust gas (G) discharged from the heating furnace (2). <IMAGE>
