Patent AT-E400780-T1: [Translated] VESSEL FOR A METALLURGICAL MELTING UNIT

The tank (1) has an upper part (2) and a lower part (3) with a collar (7). The upper part totally bridges an annular cooling device. The cooling device is in the form of an intermediate ring (4). The upper part rests on the lower part only below the cooling device, and only on the collar of the lower part, so that the intermediate ring is completely free of static load.
