Scale Soft Sensor for steel semi-products [CSS4] - Integrated

During production of steel bars in hot rolling mills there is a formation of scale on the surface of the products. It is differentiated between two scale types: primary scale and secondary scale. During the reheating of the product in the furnace the scale is called primary scale. After reheating and before rolling the scale is removed by a descaler, for instance with high water pressure. After rolling, while the product is located on the cooling bed, the secondary scale grows up.
