Abstract
Method to equalize the temperature in a heating furnace (10) with a controlled-oxidization ambient, the furnace (10) comprising at least one insulated chamber (11) cooperating with a supporting and conveying surface defined by a plurality of rollers (12), the rollers (12) including rings (35) to bear slabs (19), a plurality of burners (18) being comprised in cooperation with the upper part of the furnace (10), whereas a plurality of aspiration intakes (21) is included in cooperation with the lower part of the furnace (10), the feed to the burners (18) being adjusted in such a way as to ensure a strongly oxidizing atmosphere within the furnace (10) so as to obtain a desired and controllable layer of scale on the surface of a slab (19) in the furnace (10), this strongly oxidizing atmosphere being conveyed so as to surround and lap continuously and evenly the whole periphery of the slab (19), the furnace (10) cooperating downstream with a descaling assembly (22) to remove the layer of scale thus formed. Heating furnace (10) with a controlled-oxidisation ambient, which comprises at least one insulated chamber (11) cooperating with a supporting and conveying surface defined by a plurality of rollers (12), the rollers (12) including rings (35) to support slabs (19), a plurality of burners (18) being included in cooperation with the upper part of the inside of the furnace (10), whereas a plurality of aspiration intakes (21) cooperates with the lower part of the inside of the furnace (10), the furnace (10) comprising a plurality of diversion baffles (20) to convey and direct fumes and gases, the baffles (20) being positioned in cooperation with the burners (18) and extending vertically to a position close to the upper surface of the slab (19), the burners (18) being fed in such a manner as to create a strongly oxidizing atmosphere within the furnace (10).
