The technical development as well as the economical pressure led in the last few years to an increase of the outer diameter of steel strip coils. These new conditions ask for a new reflection on how the stability of coils having a horizontal center line could be ensured taking into account the usual storeroom floors.The rule of a ratio width - outer diameter of 1:4 for the stability of steel strip coils based on former studies has been here reconsidered because of the new storage conditions used in the cold rolling industry. A work group inside the "Technical Commission" of the Fachvereinigung Kaltwalzwerke e.V. (German association of cold rolling mills) was dedicated to the question and conducted the present study together with the chair for structural steel engineering of the university RWTH, Aachen. This study was designed to help the producers as well as the users of cold rolled steel strip in the evaluation of their storage conditions and therefore reduce the potential dangers.

[ Summary ]

In its meeting on 22nd June 2001, the Technical Committee, chaired by
Mr. Roberto Alessi, adopted the final version of the cold rollers lexicon.
By this step the members finished a project of the CIELFFA's Technical Committee which had been worked on for many years.
Here you can download the complete version with the different source languages (English, French, German, Spanish and Italian) in Excel-Format.
