SPEED SYNCHRONIZATION SYSTEM OF ALUMINUM ALLOY SLAB CONTINUOUS CASTING AND ROLLING LINE AND PRODUCTION FACILITY AND METHOD OF PRODUCTION OF ALUMINUM ALLOY CONTINUOUSLY CAST AND ROLLED SLAB USING SAME

摘要

the wholesome aluminum alloy slab continuous casting and rolling belt speed of the twin-belt casting machine and skin pass mill in order to obtain twin-belt casting machine to properly control the rolling speed and the production equipment and the manufacturing method of the speed synchronization system and an aluminum alloy continuously cast and rolled slab using the same aluminum alloy slab continuous casting and rolling line having a skin pass rolling machine is provided. These are (1) compares the line speed setting and a measured value of a slab speed during the process by skin pass rolling from the twin-belt casting machine and controlled by the roll speed of the skin pass rolling to the proportional / integral control, and at the same time, (2) line by solidification shrinkage rate of speed on the basis of the set value and control the casting of aluminum alloy target belt speed of the twin-belt casting machine, thereby tuning the roll speed of the skin pass rolling machine and the belt speed of the twin-belt casting machine.
