MODELING AND CONTROL OF PLATE THICKNESS IN HOT .

Abstract: It is still common practice in industry to handle the thickness control problem of a rolling mill around a working point. The assumption of linearity is no longer valid if the mill is operated in a wider working range. In a reversing mill this is especially the case when the plate enters and leaves the mill stand from pass to.

Rolling (metalworking) - Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is.
