内補修上特に困難を伴なうものであった。[Prior art] Continuous furnaces are equipped with rolls or other conveying means in the furnace to continuously feed the heated material and perform heat treatment efficiently, and are generally suitable for mass production and have the characteristics of being able to reduce labor. However, if scale that has fallen from the heated objects accumulates on the hearth surface, it may deteriorate thermal efficiency or cause trouble in transporting the heated objects. This work required a great deal of effort and time. On the other hand, last year, in order to save energy, some continuous furnaces were designed with a narrow space inside the furnace to the extent that the objects to be heated could pass through, but in such cases, people could not enter the furnace, so cleaning the inside of the furnace was difficult. It was especially difficult to repair the inside of the reactor.
［発明の目的］
