The invention discloses a gauge and flatness comprehensive control system of a cold rolled steel sheet, which comprises an influence coefficient storage module, an AFC (Automatic Flatness Control) system, a flatness influence pre-calculating module and an automatic flatness control system, wherein the influence coefficient storage module is used for storing an influence coefficient of bending roller regulation to flatness; the AFC system is used for receiving a gauge signal of online measurement of a gauge instrument, calculating online regulation amount of each gauge control means and sending the online regulation amount to a gauge regulation and control mechanism to complete a gauge closed-loop control function; the flatness influence pre-calculating module is used for receiving the online regulation amounts of the gauge control means of a bending roller, reading corresponding influence coefficients and figuring out a flatness deviation generated by the current bending roller regulation; and the automatic flatness control system is used for regulating the flatness according to the flatness deviation. According to the invention, adverse influences to the flatness of the cold rolled steel sheet during control of the gauge of the bending roller are effectively eliminated, the control effect of the flatness of the cold rolled steel sheet can be ensured while the gauge quality of the cold rolled steel sheet is improved, thus the grade of the cold rolled steel sheet is remarkably improved, and powerful guarantee is improved for improving gauge control quality of the cold rolled steel sheet.
Description
technical field [0001] The invention relates to the field of shape and thickness control of cold-rolled strip steel, in particular to a comprehensive control system for shape and thickness of cold-rolled strip steel. Background technique [0002] With the rapid development of domestic and foreign equipment manufacturing industries, downstream users have increasingly high quality requirements for cold-rolled strip products, especially for industries such as high-end automobiles and high-end IT product manufacturing. Cold-rolled strip steel is mainly used for punching various parts. In order to improve the life of the die and stamping precision, the cold-rolled strip steel is required to have high thickness accuracy and good shape quality. Therefore, high-quality, low-cost, high-yield cold-rolled strip product rolling has become the goal pursued by cold-rolling enterprises. [0003] For the cold-rolled strip rolling process, shape and thickness are two different technical ind...
