Abstract
A method and a regulating device for regulating a rolling process, wherein a rolling material is rolled in a rolling gap between two working rollers of a rolling stand. A target forward slip value (fs) for a forward slip (f) of the rolling material is specified, and an actual forward slip value (fM) of the forward slip (f) of the rolling material is ascertained. The forward slip (f) of the rolling material is regulated to the target forward slip value (fs) in that a lubricant rate (uR) of a lubricant is applied to the rolling material and/or at least one working roller depending on the actual forward slip value (fM) and the target forward slip value (fs).
Claims16
A method for regulating a rolling process in which a rolling material is rolled in a rolling gap between two working rolls of a rolling stand, comprising:
- specifying a target forward slip value for a forward slip of the rolling material;
- determining an actual forward slip value of the forward slip of the rolling material;
- forming, in a control path, a control variable based directly on the actual forward slip value and the target forward slip value;
- and
- applying a lubricant at a lubricant rate to at least one of the rolling material and at least one working roll based on the control variable to regulate the forward slip of the rolling material to the target forward slip value.
