Embodiment Construction

[0018] according to figure 1 The continuous casting equipment includes a mold 1 in which liquid metal, especially molten steel, is continuously drawn out from below the water-cooled mold 1 in the form of a billet 2 in the form of a billet shell. The cast strand is guided through other cooling devices, so-called secondary cooling devices, while being further cooled. According to requirements, multiple support rollers and spraying mechanisms 4 can be installed at the outlet of the crystallizer as so-called bottom roller supports and support sections. They depend on the specification and are replaced with the mold when the casting specification changes.

[0019] The cooling device includes a plurality of spray modules 3 arranged one behind the other. In the spray modules, the casting slab 2 guided along the guide roller table is applied with a cooling medium, generally water or a water-air mixture. To this end, each cooling module 3 is equipped with a plurality of nozzles 5 in the ...

Abstract

The invention relates to a continuous casting system, particularly for long steel products, having a gravity die wherefrom a cast slab (2) is continuously cast. The cast slab (2) is formed along a guide track formed by guide rollers disposed one after the other (11, 12, 13, 14), particularly a curved guide track, and substantially fed into a cooling chamber having spray heads. The guide rollers (12, 13, 14) and / or the spray heads are present in a plurality of centering modules (10) or spray modules (3) disposed one after the other, and can be adjusted substantially concentrically to the target axis of the cast slab. The risk of thermal overload of the rollers and of damage to the slab surface is thereby significantly reduced, and the symmetrical cooling is also ensured.

Description

Technical field [0001] The present invention relates to a continuous casting device, in particular for long steel products, according to the preamble of claim 1 and a continuous casting method according to the preamble of claim 13. Background technique [0002] In continuous casting, it is well known that liquid metal such as molten steel is poured into a cooled mold, and the continuous casting slab is drawn downward from the mold while a shell is formed. The continuous casting slab is guided through another cooling device, the so-called secondary cooling device, along a guide roller table consisting of a plurality of guide rollers arranged one behind the other, while applying a cooling medium (spray water, water-air mixture) and through contact The guide rollers are cooled by radiation heat dissipation. [0003] For quality considerations, it is important for the continuous casting slab to be symmetrically cooled in terms of its cross section. To this end, on the one hand, the d...
