摘要
PROBLEM TO BE SOLVED: To provide a line velocity tuning system where, in an aluminum alloy slab continuous casting-rolling line having a twin belt type casting machine and a skinpass rolling machine, the belt velocity of the twin belt type casting machine and the roll velocity of the skinpass rolling machine are suitably controlled for obtaining a sound aluminum alloy continuously cast-rolled slab, to provide slab production equipment, and to provide a method for producing a slab.;SOLUTION: (1) The actual value of the velocity of a slab during the progress from a twin belt type casting machine to a skinpass rolling machine and a line set velocity are compared, and the roll velocity in the skinpass rolling machine is PI-controlled, and simultaneously, (2) the belt velocity in the twin belt casting machine is controlled based on the line set velocity and the solidification shrinkage percentage of an aluminum alloy as the object for casting, thus the belt velocity in the twin belt casting machine and the roll velocity in the skinpass rolling machine are tuned.;COPYRIGHT: (C)2007,JPO&INPIT
