The material to be charged is constituted in each case by mixing the various alloying elements into the desired charging material. After the molten metal has been transferred into the holding furnace (Warmhalteofen), this charging material is converted into one strand or two strands. It is compacted into a metal strip in a horizontal strand continuous casting machine. The casting cross section is, for example, 200 × 15 mm. The holding furnace is generally induction heated. It is cast directly from a holding furnace into a water-cooled graphite mold, with a casting speed of about 140-200 mm / min being common. The cast metal strip is gripped by a drawing machine and is drawn and pushed back alternately in defined cycles, the holding time being preserved. It is known and common to draw metal strips with a stroke length of 12 to 19 mm and to bounce back after a short holding time of 0.1 to 0.5 seconds. After another short hold time, another rebound of 0-1 mm is made before the next drawing stroke is started.

Rough rolling and finish rolling are generally performed in a reversible operation. An annealing step and a recrystallization step are interposed between the rough rolling pass and the finish rolling pass, and a bell-shaped heat treatment furnace is used at that time.

価なものとする。[0006] Other known currency materials can be produced without problems from cast metal strips in the manner described at the outset, whereas the material known as Nordic Gold is previously hot-rolled. It has been conventionally thought that it is not suitable to be manufactured by a continuous casting method as a metal strip that can be directly cold-rolled without using a metal strip. From the alloy composition of these copper alloys and their quantitative proportions, the material cracks, especially during cold rolling, so that the rolled state (walzwarmen Zusta
nd) could only be rolled. Cold rolling of metal strips is only possible after a number of hot rolling passes, which makes the production by this method cumbersome and expensive.

Long retention time lasts. This process has been found to significantly reduce the tendency of the metal strip to crack in subsequent processes.
Another significant improvement of the process and the consequent contribution to enabling this troublesome material to be produced in a known manner is provided by a second overturn which takes place immediately before the next drawing operation. This overturn is much longer than in the known method and works down into the mold by its approximately 1.9 mm.
