Mechanics of Cold Rolling of Thin Strip. The main aim of this project is to generate a new theory for the cold rolling of thin strip (thickness: 0.1 - 0.15mm) when the work rolls contact beyond the edges of strip.

Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that c ....Mechanics of mixed film lubrication in strip rolling.

Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that can provide a much better understanding of the rolling process at speeds higher than previously possible, and help to improve its productivity as well as product quality.Read moreRead less

Strip shape performance at tandem cold mill. The shape of the strip at the cold mill are affected significantly by machine conditions and key process variables, and yet the inter-relationship between these key areas are not known and operators rely on trial-and-error methods to operate the mill. At high speeds, the shape of the strip leaving the mill is not good, causeing problems to rolling mills downstream.

This project will propose a novel, cost-effective surface engineering technique that synthesizes an effective surface coating during the pipeline manufacturing process. Seamless Steel pipelines conveying oil and contaminants can have a short life due to erosion-corrosion. The need to develop mitigation techniques against the internal corrosion-erosion has increased significantly as steel pipelines are used in more aggressive environments. The project expects to develop an integrated surface coating during the manufacturing process, which will provide long-term integrity and extend the life of the pipeline. The forensic evaluation and prediction of the life performance of the pipeline will quantify how the coating will combat effectively erosion-corrosion related problems in oil pipelines.
