摘要：
A tower furnace for the heat treatment of metal strips comprises a muffle (3) extending over the entire furnace height, through which muffle passes the strip (6). At the top of the muffle (3) an insulated stopper (1) with an electric heater (2) has been inserted into the muffle (3). Below this stopper (1) a gas-heated preheating space (4) is provided in the muffle (3).
