Abstract

Tower furnace has a preheating section and a high temperature section connected above it forming a housing. The preheated section equipped with a gas-heated muffle has a stop in the muffle made of heat-insulating material for the high temperature section. High temperature section is provided with gas-heated muffle which surrounds the stop from the outside and is connected to it via a liquid seal. Preferred Features: The stop has a passage cross-section for the metal strip to be treated with a low width measured vertically to the metal strip and corresponding to the half radius of the stop.
