The combination of these two lines is a mix of high-efficiency features. The continuous pickling line coupled with a multi-stand tandem cold mill provides significant improvements in terms of plant efficiency, productivity, product quality and cost savings.
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.
Mills for cold reduction mill technology full-liners, who keeps the state-of-the-art-design competence with enhanced technology for the various mill Cold rolling mill type Typical mill stand types Production capacity (t/y)* Strip speed Type (m/min)* functions.
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-
Innovative technologies. One of the most outstanding products in the ANDRITZ Metals portfolio is its patented S6-high rolling mill. This mill is increasingly used for stainless steel strip rolling, either as in-line tandem mill for cold rolling or in the entry section of hot-strip stainless steel annealing and pickling lines to roll black hot strip with highest pass reductions and simultaneous ...
It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types. The tandem mills consist of number of non- reverse roll mill arranged in one ...
Casey buys and sells cold rolling mill stands which may be a stand alone mill or part of a tandem cold strip mill. Cold mills can be two high rolling mills or four high rolling mills. Some single stand cold mills reverse direction, while tandem mills are continuous. Contact Casey Equipment for a quote on used cold strip mills for sale.
EDT rolling transfers this exact finish onto the strip during the final rolling pass. Crucial here is a specific roughness on the work rolls created by electric discharged texturing (EDT). Once it is applied to the roll barrel, this roughness transfers precisely onto the strip surface.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

Dec 01, 2010· The tandem cold rolling of metal strip is a large, highly complex nonlinear multivariable process the control of which poses a significant engineering challenge. Existing controllers have proven to be susceptible to disturbances and uncertainties in process variables and attempts to increase robustness to these phenomena have had their own drawbacks so a new approach is needed.
The cold rolling mills are essential to reduce strip thickness while guaranteeing strip surface quality. With more than 100 references worldwide over last 60 years, Fives' range of DMS 20Hi cold rolling mills (CRM) is proven for applications in stainless and silicon steels, as well as for nonferrous materials.

The tandem cold rolling of metal is a high complex engineering process, with interactions of the multiple process variables, non-linearities and time delays, both extremely dependents of the operating conditions and of the speed rolling mill. In general, the rolling mill automation technology to .
The tandem mills consists out of a series of rolling stands that thin the steel strips. One of our tandem mills works exclusively for the automotive industry, the other produces products for the remaining branches. After having passed through the cold rolling mill, the steel strip is hardened.
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.
A Cold Mill rolls coils of pickled steel from the pickle line at ambient temperature, using coolant oil. The cold mill produces steel and stainless steel and is also used for aluminum, aluminum foil, and copper. There are several types of mills such as 2-High, 4-High, 6-High, 12-High, 20-High, and Sendzimir Mills that have a variety of types of flatness control operations.
