Benefits of technology

The invention provides a casting wheel that allows for efficient heat dissipation and allows for repeated post-machining of the casting channel.

Problems solved by technology

This factual situation leads to a permanent thermal cycling and, in the worst case, to premature crack formation.
However, the drawback resides in that, once cracks form, it is no longer possible to postmachine the casting wheel.
The same problem was encountered when working with casting wheels that did, in fact, have a larger mold bottom thickness, into which deep cooling grooves had been milled to improve heat dissipation.
Another problem is that deposits form because of the often inadequately filtered cooling fluid, typically cooling water, and because of the evaporation of the cooling water on the hot surface of the casting wheel.

Embodiment Construction

[0015]The casting wheel according to the present invention for manufacturing strands of metals or metal alloys includes a peripheral casting channel that is bounded over a partial length by a circulating band. Below the casting channel, a mold bottom is provided for being cooled with a cooling fluid. The inner side of the mold bottom facing away from the casting channel is provided in accordance with the present invention with a profiling that has a profile height of only 0.5 to 6 mm; in particular, the profile height is within a range of from 0.5 to 3 mm. The profiling preferably has a profile height of 2 mm at a maximum.

[0016]On the one hand, such a low profile height makes it possible to significantly improve the cooling of the casting wheel since the surface, that the cooling fluid comes in contact with, is considerably enlarged. On the other hand, the profiling is so low, due to the limited height thereof, that the casting wheel may be lathed several times, making it possible f...

Abstract

A casting wheel (1) for manufacturing strands of metals or metal alloys having a peripheral casting channel (2) that is bounded over a partial length by a circulating band (11); below the casting channel (2), a mold bottom (3) being provided for being cooled with a cooling fluid. The inner side (7) of the mold bottom (3) facing away from the casting channel (2) is provided with a profiling (6) that has a profile height of 0.5 to 6 mm.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is the U.S. national stage of International Application No. PCT / DE2013 / 000095 filed on Feb. 22, 2013 which claims priority from German patent application serial no. DE 10 2012 007 312.7 filed on Apr. 13, 2012, the entire contents of both of which are hereby expressly incorporated by reference into the present application.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to a casting wheel for manufacturing strands of metal or metal alloys.[0004]2. Description of Related Art[0005]A casting wheel has a peripheral casting channel that is outwardly bounded by a circulating band over a partial periphery of the casting wheel. The band is made of steel. The casting channel is cooled by the spraying on of a cooling fluid, in particular water. Such casting wheels are used in wire manufacturing, for example, in the casting of liquid non-ferrous metal, such as copper or al...
