Abstract

Abstract Method for heating a metal slab Method for heating a metal slab (4) which is transported in a longitudinal direction (L), vertically to a cross-direction (T), through an industrial furnace (1) , in which the metal slab (4) is heated, which metal slab (4) is then transported on a rail device (101) out from the industrial furnace (1) to a subsequent processing step (8). The invention is characterised in that the flame from at least one DFI ('Direct Flame Impingement') burner (102,104) is caused to impinge upon a part of a first surface of the metal slab (4) in at least one location which corresponds to a point on the under side surface of the metal slab (4) which, during the passage of the metal slab (4) through the industrial furnace (1) , has constituted, constitutes or will constitute a contact point between the under side surface of the metal slab (4) and the rail device (101) , and in that a temperature gradient in the metal slab (4) , which arises as a consequence of the local cooling of the metal slab (4) through the contact with the rail device (101;201;301), therefore is counteracted by the local heating using the DFI burner (102,104 ,-204;304) .
