PROBLEM TO BE SOLVED: To provide a continuous heating furnace where inside of furnace is partitioned into a plurality of heating zones and where exhaust ducts for discharging exhaust gas are provided at least in each of a plurality of the heating zones on the inlet side, and which can easily perform both a rough adjustment and fine adjustment of the amount of exhaust gas to be discharged in each exhaust duct.SOLUTION: In a continuous heating furnace where inside of the furnace is partitioned into a plurality of heating zones and where exhaust ducts 6 for discharging exhaust gas are provided at least in each of a plurality of the heating zones on the inlet side, the exhaust duct includes a cylindrical part 8 having a damper 7 for adjusting the suction amount of the gas in the furnace and a hood-shaped atmosphere open part 9 disposed to cover an upper end portion of the cylindrical part 8. The cylindrical part has a slide structure 10 where an upper end portion can slide freely in a vertical direction. |
