Abstract: For a kind of double roller production line and its distributed computer controlling system, a new method is put forward, which uses dynamic burden distribution between rollers to reduce latency time and improve the working rhythm. Using the high quality schedule setup program as simulatior, collecting experience of workers to establish a fuzzy controller and combining them to form a optimizing iterative process, this method tries to seek a middle billet height and temperature which will make the billet has the lest time difference between rollers. Off line simulation and on site test prove its feasibility.
