continuous casting

The use of production related, but notable smaller plants compared to production facilities, allow the development of plant technology and the testing of new alloys under the same conditions as in later production, but in significantly more economical test quantities. The combination of these Production related plants (see above) and using scientific methods of materials research allows efficient development of process-optimized alloys and industry-related process developments.

The continuous casting process

The continuous casting process is used to produce semi-finished materials for further processing in forming processes.

Extrusion-billets: Round or oval billets for rods or hollow profiles in various cross-sections
Rolling slabs: Rectangular bars for sheets

Depending on the casting direction, the methods are distinguished between vertical and horizontal strand casting.

In vertical continuous casting, the products are moved downwards from the casting machine. After reaching the maximum depth of the plant, the casting is stopped, and the strands are removed from the system.

In the horizontal strand casting, the strands are pulled horizontally out from the casting system and cut into required lengths with flying saws. The casting runs continuously until metal in the furnace runs out.
