Claims

[Scope of utility model registration request]

A heat shielding pipe with a notch opening formed in the center and above the pipe is hung horizontally on both inner walls of the tunnel hearth furnace, and a water-cooled roll is placed inside the heat-shielded pipe. A tunnel-type hearth roll furnace characterized by being arranged so that a portion of the furnace is exposed through a notch opening to reduce water cooling loss.
