Summary:The laying head's role on the finishing end of a rod rolling mill - to form a product rolled at very high speed into a helical ring pattern - means that its efficient operation is critical to the success of the rolling process. As speed capability in the finishing blocks has continued to increase well beyond 100 m/s, the importance of this piece of equipment has intensified. The key to success in sustaining or improving operations is to selectively target existing equipment that can be improved with new technology and increase the level of automation. Modernisations can provide consistent operations with higher speeds, less maintenance and downtime, longer wear part life for more 'up time' between changes, and as little operator intervention as possible. Regarding the laying head, the most common industry problems faced by rolling mill managers are head and tail end formation, packaging and pattern-related issues.
