Patent number: 7028748Abstract: A plant for the continuous casting of aluminum strip, according to current construction type, has two counterrotating continuous casting rolls (1, 2), between which a casting gap (4) is formed. According to the present invention, the 1. continuous casting roll (1) is made of a copper material at least in its circumferential edge region, and the other, 2. continuous casting roll (2) is made of a steel material at least in its circumferential edge region. The copper material should have a thermal conductivity ?K of 230 to 260 W/m·K, and the steel material should have a thermal conductivity ?S of 30 to 40 W/m·K. Rejecting the prevailing idea that casting can only be performed with two continuous casting roll materials of the same kind, so as to ensure uniform crystal growth, a continuous casting roll pairing of steel and copper is provided in the present invention.Type: GrantFiled: January 14, 2005Date of Patent: April 18, 2006Assignee: KM Europa Metal AGInventors: Dietmar Kolbeck, Hans-Günter Wobker, Klaus Maiwald
