HEAT SHIELDING APPARATUS FOR VERTICAL CONTINUOUS ANNEALING FURNACE

摘要

PURPOSE: A heat shielding apparatus for a vertical continuous annealing furnace is provided to perform heat treatment on a metal strip while the strip is continuously transported. CONSTITUTION: A shielding apparatus for intercepting heat from a heating source disposed in a vertical continuous annealing furnace includes a double-walled tube(20) having an outside atmosphere suction port(23) projected horizontally or downward to be exposed to an outside atmosphere, and an exhaust port(25) projected upward to be exposed to the outside atmosphere.
