FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, specifically to a method and a device for preliminary treatment of a rolled article. Method for preliminary treatment of a rolled steel article before hot rolling includes preliminary heating of rolled article in preheating furnace using burners, removal of scales in device for removal of scales and heating article in heating furnace using burners. Burner is fired at conditions lower than stoichiometric conditions, carbon carrier while holding article in furnace in reducing atmosphere. Further, method includes introduction of a first part of exhaust gas and oxygen into preheating furnace and post-combustion of first part of exhaust gas in preheating furnace. Amount of oxygen is selected to allow holding of article in preheating furnace in an oxidative atmosphere.
EFFECT: providing energy-efficient heating and thorough release from scale.
