FIELD: process engineering.
SUBSTANCE: invention relates to reconditioning of continuously cast slab surface 1, particularly, of steel, before rolling and device to this end. Cast slab 1 is directed via furnace 2 to remove scale. Slab surface is subjected to reconditioning at, at least, one furnace section 3 by maintaining atmosphere consisting of inert gas of hydrogen H2 or pure oxygen at furnace section 3. Note here that furnace 2 has adjoining section 4 whereat slab surface is oxidised in transfer direction F ahead and/or behind furnace section 3.
EFFECT: minor scale on slab surface.
