Ea devices for removing the cooling liquid are known, which have annular Auff ^ n ^ er with slits directed towards the surface of the cast block. Through the slots Wiru blown compressed air to remove the coolant from cer To remove the surface of the semi-finished product and to lead to a collecting container. The Aulfinger are often at the bottom of the Collector mounted and regarding the theoretical The axis of the casting machine is rigidly fixed.

The immovably arranged catcher rings have serious disadvantages. Namely, the semi-finished product is derived from the theoretical axis dwr machine removed, the becomes fixed Attached catcher destroyed by the semi-finished product and the latter is clamped in the catcher.

When using aul catcher η, which surrounds the hemisphere, you have to keep in stock oyster the ice legs of different catchers in order to have the pissing catcher for everyone on the casting machine divisible helmet cross-section.

The object of the invention is to eliminate the disadvantages mentioned and to eliminate the risk of bruising caused by compressed air On catchers and the reduction in the number of catchers required for different semi-finished product cross-sections.

The invention is based on a device for removal the cooling liquid below the secondary cooling Machines for continuous metal casting, where I * ft radiate against the semi-finished product coming from the secondary cooling

With this arrangement one achieves the advantage that the catchers 5 follow the movements of the Bollen 2 and daduroh Always keep the correct distance to the widths during pouring Surfaces aea semi-finished product 1 have.

Each Wngen 8 also has a Bolle 11, which runs on the narrow side of the semi-finished product. Hydraulic winches 12 control the movements of the carriages 8 with their piston rods 1J.

during operation, the hydraulic winches 12 press the i.agen 6 with their bulbs 11 against the narrow sides of the semi-finished product. This ensures that the semifinished product has deformations and there is no risk of damage the interceptor 7 consists in that the carriages 8 automatically move the gate or urüok according to the deformations.

The semi-finished product 1 runs through an opening la bottom of the collecting container 14. In this, the air jets that come from the catchers 3 and 7, blown away by the HaIbseug Collected water. Dec collecting container 14 has a high arched belt 15 ″ so that the water does not fall on the wagon 8.
