Features 01

Expected Problems

・Isn't inadequate hot-rolling skin-pass rolling capacity a problem?

・Isn't it necessary to repeat skin-pass rolling or reduce the rolling speed due to strip meandering during rolling, etc. ?

・Isn't it hard to increase production of materials with severe quality standards?

Features 02

Technology highlight

・Prediction of the strip entry-side shape from actual data during hot rolling and set up of the optimum skin-pass rolling conditions.

・Satisfies both the allowable elongation rate and shape improvement by model prediction control integrating sensor data and optimization/simulation technique in real time.

・Control of high-speed telescope (meandering) by meandering simulation technique based on a large deflection strip model.
