Document Type and Number:
WIPO Patent Application WO/2006/061903
Kind Code:
A1
Abstract:
Gas atmosphere heat treatment equipment capable of performing heat treatment efficiently while enhancing productivity by lowering the frequency of operation shutdown due to maintenance work, or the like. The equipment can be attained by providing a metal component conveying means in a furnace, providing a means for heating the metal component in the furnace, covering the fixing parts of the conveying means and the heating means to the furnace body with a casing from the outside of the furnace body, and providing an atmosphere gas supply unit for supplying atmospheric gas into the casing while pressurizing. The conveying means can be constituted of a plurality of ceramic rollers arranged continuously in the furnace body, and a driver for rotation-driving the ceramic rollers.
