Abstract
A tower furnace for heat treatment of metal strips having a pre-heating section (3) and a high-temperature section (5) connected thereto at the top forming a housing (4) separate from the pre-heating section (3) is described, whereby the pre-heating section (3) equipped with a preferably gas-heated muffle (7) exhibits a connecting stopper (6) made of heat-insulating material for the high-temperature section (5) inserted into the muffle (7). To create advantageous structural conditions it is proposed that the high-temperature section (5) is also fitted with a preferably gas-heated muffle (12) which encloses the connecting stopper (6) externally and connects to this in a gas-tight manner preferably by way of a fluid seal (14).
