Rod Mill Modernization At Onesteel Laverton For Increased Productivity, Utilization And Product Quality

Several improvements were made to the single strand rod mill at Laverton to increase production, reduce maintenance and improve several aspects of product quality. With changes to the water cooling line and control system, cobbles could be significantly reduced, more consistent properties obtained and yield improved. An upgrade of the laying head enabled vibrations to be reduced and thus allowed for higher speeds on small sizes. With potential for dramatically increased pipe life, a new pipe support and laying pipe system provided for improved laying pattern on small sizes and thus more uniform cooling on the conveyor and better coil package. This paper discusses details of these equipment and control system upgrades and the resulting benefits that have been realized from the project.
