A method and device for descaling having a lower surface of a cast strand from a continuous casting plant.

摘要

The present invention relates to a method and a device for descaling, in particular of oscillation marks (30) surfaces having (2, 3) of a cast strand which can be produced in a continuous casting process (1), in particular of thin slabs. The thin slabs are in one of the casting arrangement subsequent hot strip mill (32) with reheating furnace (11) and, preferably with a plurality of roll stands (33) has a reduced thickness. The cast strand (1) is made between the end of the strand support (10) and before entry into the equalizing furnace (11) or upstream of the entrance into the roll stands in a limited region (29) by at least double deflection from a horizontal transport direction in the region of each deflection (4, 5) an elongation of its surfaces (2, 3), is subjected to. The rod surfaces (2, 3) are used in particular in the deflection regions (4, 5) by means of hard water jets (8, 9) is subjected to an intensive cleaning.
