Abstract
A tower furnace for heat treatment of metal strips having a pre-heating section ( ) and a high-temperature section ( ) connected thereto at the top forming a housing ( ) separate from the pre-heating section ( ) is described, whereby the pre-heating section ( ) equipped with a preferably gas-heated muffle ( ) exhibits a connecting stopper ( ) made of heat-insulating material for the high-temperature section ( ) inserted into the muffle ( ). To create advantageous structural conditions it is proposed that the high-temperature section ( ) is also fitted with a preferably gas-heated muffle ( ) which encloses the connecting stopper ( ) externally and connects to this in a gas-tight manner preferably by way of a fluid seal ( ).
