FIELD: process engineering.
SUBSTANCE: invention relates to continuous CSP process from continuous teeming to hot rolling at production line. Slab top and bottom surfaces are subjected to oxidation. Before said oxidation scale is removed from slab surface. 4 mm deep slab (5) layer is subjected to oxidation. Oxidation is executed by oxidising flame of oxidising gas mix fed by oxidising device (21) including sprayer or sprayers to produce solid or liquid oxidation product at slab surface.
EFFECT: higher surface quality of slabs (5) with depth of up to 400 mm.
