Thickness precision is one of the most important quality indexes in strip rolling process [2, 3].Monitor automatic gauge control (AGC) based on hydraulic roll gap control system is widely used in modern strip rolling mills [4–7].In monitor AGC system, gauge meter is used to measure strip gauge derivation, which is installed at the delivery side of the finishing mill.

The life of any hydraulic system depends on keeping contaminants out of the oil. This is hard to do with the cover plate removed. The reservoir for the unit must be large enough to handle all of the oil contained in the machinery (for example a CC roll) if there is a situation that requires the machinery be completely drained.

The identification of a hydraulic system on a hot rolling mill is described. The rolling mill is in operation at The Danish Steelworks Ltd. in Frederiksværk, Denmark. The hydraulic system is used for thickness control of the rolled plates. A non linear model for the system is derived and transformed to discrete time.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

The role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness 0.8–20 mm. Fig. 1 shows a typical layout of a hot strip mill. Slabs are heated up to around 1200 °C in reheating furnaces and then rolled on two reversing roughing mills which reduce the thickness of bars to ...
