PURPOSE: An ambient heating device is provided to prevent a dent generated by the condensate of wet steam falling onto the surface of a material or scratches caused by the dent. CONSTITUTION: An ambient heating device comprises an ambient heating unit, an ambient gas supply unit, and an ambient gas discharge unit(210). The ambient heating unit includes a heating stand(130) heating a material by using the ambient gas of high temperature. A fracture stand making the temperature of a steel sheet strip uniform can be connected to the heating stand. The ambient gas supply unit supplies ambient gas. The ambient gas discharge unit discharges the ambient gas heated the material. The ambient gas discharge unit discharges the wet steam generated when heating the ambient gas or ambient gas heated the material. |
