Abstract

The given report represents an analysis of modern technological hot strip rolling lines in terms of development direction of equipment and technologies for coiling of hot rolled strips with the target to relieve the choice of the line of modernization of existing equipment or planning of new one, including the coiling technology. There is given a description of the main factors influencing the deterioration of strip head end quality in the commencement of the coiling process and methods to avoiding these. There are described key parameters for technological engineering of down coilers with the goal to achieve the production of high quality coils. There is given a large coverage of the issue of the new generation type of down coilers – "Power Coiler" for coiling of high-strength pipe steel grades, group "X" (X100-X120).
