ANNEALING FURNACE, ANNEALING FURNACE CONSTRUCTION METHOD, AND PREFABRICATED STRUCTURE

摘要

Provided are: an annealing furnace which can be constructed by applying a prefabrication method even in the case where the furnace is large in length; a method for constructing said annealing furnace; and a prefabricated structure. This annealing furnace is equipped with a case and multiple rows of rollers for conveying steel strips to the top and bottom of the interior of the case, and is characterized by having: multiple horizontal division surfaces that divide a furnace body in the horizontal direction; and vertical division surfaces that divide the respective strips horizontally divided by the horizontal division surfaces further in a direction perpendicular to the longitudinal direction of the furnace body.
