The multi-objective optimization of the SmartCrown intermediate roll profile for a cold rolling mill was proposed in this paper in order to improve the strip flatness quality. A coupling model of roll profile and strip flatness was established, and the roll gap profile, roll gap crown adjustment range, rolls contact pressure, and strip flatness under different intermediate roll profile ...
SmartCrown was a new system developed by VAI for improving the strip profile and flatness control first applied in 1700 mm tandem cold rolling mills at Wuhan Iron & Steel (Group) Corporation (WISCO).
Tandem Cold Metal Rolling Mill Control deals primarily with a novel and practical advanced method for control of the tandem cold metal rolling processes based on the state-dependent Riccati equation technique which is recently emerging as a useful method for control of complex nonlinear systems.
Cold rolling is accomplished by processing steel strip through a series of tandem rolling mill stands. Each stand has vertically stacked rolls that are powered by huge motors to impart high compressive stresses into the strip. Hot-rolled, pickled coils are fed into the cold rolling mill from an entry-
Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to 2.5 million tons of cold rolled steel annually. The advantages of cold rolling. Cold rolled products have the following advantages over hot rolled: greater dimensional accuracy
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
The SmartCrown profile and flatness control technique was first used on wide strip tandem cold rolling mills at WISCO.During operation,some problems were found,for example,the shifting stroke of the SmartCrown work rolls couldn't be used well enough and the rolls were worn very badly and non-uniformly.Through using the ANSYS,the three-dimensional finite element roll system model was built …

COUPLED PICKLING LINE & TANDEM COLD MILL High-capacity production of high-quality products For a wide range of products, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and cold-rolling processes.
A cold rolling mill and method for cold rolling is disclosed. The cold rolling mill includes at least two tandem four-high reversing mills with at least one tension reel on each side of the tandem mills. Bridle roll units may be positioned on each side of the tandem, reversing mills to allow the cold rolling mill to be utilized as a temper mill.
Tandem cold rolling mills are named by their stand arrangement and designed as "sheet mills" if they reduce hot band to sheet gauge or "tin mills" if they roll the same incoming material to tinplate stock. A typical five stand tandem cold rolling mill is illustrated in Figure 1.
