Ulbrich has been supplying metal strip in over 165 alloys for multiple generations. Working with our inhouse equipment and rolling mill team, your order of precision strip steel can be slit, cuttolength, rolled to the thinnest gauges, annealed to various common or custom tempers, and more.
Cold rolled alloy steel strip has high requirements for production technology. In steelmaking, hot rolling, cold rolling, heat treatment and finishing of the various processes are more difficult to produce, its full process of consistent manufacturing technology, especially hot rolling .
Types of cold mill: a) Reversing, b) Nonreversing c) Tandem strip rolling mill  Choosing the correct type of cold mill depends on the exact range of products that is desired to be produced. Cold mills are classified into few egories according to their thickness ranges and speeds. To determine the

Cold Rolled Strip Steel Finishes. Coldrolled strip steel finishes are usually specified to one of the finishes below. Number 1 or Matte (Dull) Finish: A finish without luster produced by rolling on rolls roughened by mechanical or other means. This finish is especially suitable for paint adhesion.
Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3D finite element
The material requirements of copper and copper alloys, including brass, bronze, and ever more new materials, are what determines the design of a cold rolling mill. It depends on your product mix and its required capacity whether the best solution is a tandem nonreversing or a reversing cold mill. SMS group offers you CVC ® plus 4high, CVC ...
In order to analyze the effect of entry strip thickness, entry strip crown and intermediate roll shifting on strip profile and rolling force distribution, a three dimension finite element model of rollsstrip in UCM mill was established and employed. The results showed that the increases of entry strip thickness and entry strip crown would lead to the increase of exit strip crown and edge drop ...
Thin strip profile control capability of roll crossing and shifting in cold rolling mill . Abstract . Controlling cold strip profile is a difficult and significant problem has been found in industry during thin strip rolling. At present choosing the new type of strip rolling mill is the one of main methods to control
strip previously cold rolled on a mill of the first group and 1 meter or less in width and roll to thin gauges that, in some cases, are as thin as mm. The end product is very often bright annealed, may be further slit into narrower widths, and is shipped usually in smallerweight
· Abstract On the basis of SIMULIA Abaqus finiteelement software, the stress and strain in the rollers of a fourhigh rolling mill may be mathematically described. The convex–concave (CVC) profiling of the rollers and the axial shift of the working rollers are taken into account here. The transverse profile of the coldrolled strip obtained by simulation is verified experimentally. The ...
