Laying Head Pipe Upgrade Increases Long Rolling Mill Utilization
07/25/2013 - A new laying head technology upgrade recently developed by Siemens Metals Technologies extends pipe life to record levels in long rolling mills running at speeds of 100 meters per second.
A new laying head technology upgrade recently developed by Siemens Metals Technologies extends pipe life to record levels in long rolling mills running at speeds of 100 meters per second. Thanks to a novel proprietary material, up to 130,000 tons of rod can be rolled without pipe changes, resulting in significantly fewer production interruptions.
Laying head pipes are a crucial element of laying heads in long rolling mills. As part of a broader redesign of the Morgan High Speed Laying Head, the SR Series upgrade, with its new regenerating wear zones, eliminates vibration challenges, improves laying patterns and offers a more consistent formation of head and tail ends. It can be retrofitted easily to existing arrangements.
Typical mill configurations for rolling 4.5- to 8.0-mm rods require frequent laying head pipe changes after just a few thousand tons of production. The new field-tested technology has extended pipe life to as much as 130,000 tons. This reduces maintenance requirements, production interruptions and spare parts storage.
The SR Series includes four options for mill owners, from basic pipe to treated and composite choices. The top performer of the SR Series is the DM2, which features the proprietary material, Revotech, exclusively designed by Sandvik Materials Technology and only available for the Morgan High Speed Laying Head. Tested at several rolling mills, the SR Series technology has delivered record-setting performance within the broader redesign of the Morgan High Speed Laying Head.
Sandvik Materials Technology is a world-leading developer and manufacturer of products in advanced stainless steels and special alloys for the most demanding environments, as well as products and systems for industrial heating. It is a Business Area of Sandvik AB, a high-technology engineering group headquartered in Stockholm, Sweden. Founded in 1862, the global industrial group has 49,000 employees and representatives in 130 countries.
