Abstract:

When considering cold strip, one can see the continuously expanding trends in newly developed, higher-strength (HSS) steel grades. This demand is due to the increasing ecological awareness of the fact that the available resources have to be utilized more efficiently. One – but not the only one – important driver is the automotive industry.
Cold strip producers are increasing the share of HSS in their product range. This comes with special requirements on the existing production equipment and may lead the plant operators to the decision to upgrade the facilities.
The paper presents new technical solutions for various types of cold rolling mills. The improved tension reel for tandem cold mills allows the winding of thin high-strength strips under high tension from the start.
Apart from the tension reel improvement, there are a couple of interesting new technical features for better utilization of the mill, especially when processing advanced grades. An example is the new enhanced bending system. This is applicable for single- and two-stand reversing cold mills as well for tandem cold mills. The same applies for the Sieflex-HT® gear-type drive spindle for high torque transmission.
When it comes to rolling ultra-high strength grades and stainless steel, the Multipurpose Mill offers a solution. Since it can be operated with 4-high as well as 18-HS roll inserts, very high pass reductions can be achieved. The design of the roll cassettes allows a fast change between the operation modes. The Multipurpose Mill is a very good solution, when the operation of several specialized rolling mills, e.g. a 20-high mill, is not profitable.
The paper focuses on latest examples of advanced mechanical design solutions but gives also an impression about further new developments, which aim to increase the degree of digitalization and “intelligence” of the mill. These features are called “Intelligent Components”. Each of the feature mentioned can be applied in existing as well as in new mills.
