摘要

Furnace for heating a continuous strip-like hot material (2), especially a steel strip, has a nozzle (5) for feeding flue gas vertically onto the surface (6) of the hot material, and devices (7) for producing turbulence in the nozzle. The devices allow the flue gas to flow from the nozzle in a turbulent spiral-like flow.
