The invention relates to a method and device for continuously casting metal, particularly steel, whereby molten metal (6.1) is continuously cast in a cooled ingot mold with a casting speed (3) while forming a meniscus (7), and a cast product is continuously drawn out of the ingot mold in a direction of casting (3.1). The ingot mold, which has an ingot mold inlet (12) and an ingot mold outlet (8), is a water-cooled copper ingot mold having ingot mold cooling water channels (10.4) with a channel inlet and a channel outlet through which cooling water flows. Said water has an entry pressure p0 (15) at the channel inlet and an exit pressure p1 (15.1) at the channel outlet. The inventive method and device should be improved as to impede or prevent the high thermal load T of the ingot mold in the meniscus. To this end, the invention provides that, during a controlled adjustment of the water flow speeds in the ingot mold cooling water channels (10.4) and during a monitoring of the pressure loss DELTA p of the cooling water, the cooling water direction of flow (12) should correspond to the direction of continuous casting while forming a Nusselt layer that, at the height of the meniscus (19.1), is thinner than the Nusselt layer at the ingot mold outlet (19.2). |
