Speaker Company Subject Size
Mark Nickerson Corus - BBM Technical Dept Bulge and Bite rolling at the Bloom & Billet Mill  
Mark's winning Young Member's Paper describes a novel rolling technique to reduce 'fishtailing' when rolling semi-finished products, which gives dramatic yield improvements.
Mr Andrew Wilson Corus - Long Products Div The Development of the Pre-Cambering Process for Ultra Long Rails at the Medium Section Mill  
Young Member's Paper Winner 2010. This paper aims to describe the current understanding of cooling distortion of rails and pre-cambering strategies gained over the last three years, which has led to a world-class performance at the Medium Section Mill (MSM). At the start of the commissioning process for rail in 2006, very little was known about pre-cambering rails over 80m in length and previously used parabola type pre-camber shapes proved to be unsuccessful. Very little information has been published on the subject of cooling distortion and therefore a new theory to explain the behaviour of ultra long rails upon cooling had to be deduced from first principles.
Dr Fredric Montfort Corus - Scunthorpe, UK Development of Bainitic Rail Steel  
Bainitic steels are being considered as possible candidates to replace the traditional pearlitic rail steels, as carbide free bainites developed for rail applications have shown increased ductility and toughness compared with pearlitic rails. This paper reviews (a) the basic principles of steel metallurgy, (b) the importance of heat treatments that lead to the formation of pearlitic and bainitic rail steels and (c) the characteristics of rail bainitic microstructures and their mechanical properties. The manufacturing process of bainitic rail steel is described, including steelmaking, casting, rolling and rail finishing. Finally, the value of bainitic rail steel, which is a differentiated product, is also outlined.

Mr Neil P Hardy Corus, Scunthorpe Increasing Rolling Rates on Special Plates  
During thermomechanical controlled rolling hold periods cause delays, if these can be reduced then the throughput can be increased. The Technology Developments section of the Plates Technical department at Scunthorpe Plate Mill conducted a project to investigate how the roughing mill de-scaling sprays could be used to increase the cooling rates of normalised rolled (NR) and thermo mechanically controlled rolled (TMCR) products during the hold period.
Chris Lisle Corus - Steelmaking Technical Dept. The Development of Rare Earth Particle Dispersed Steels  
The desirable properties of strength and toughness have traditionally been achieved in steel by promoting a fine-grained microstructure through control of the austenite-toferrite phase transformation such that the nucleation of ferrite crystals takes place at the boundaries of fine austenite grains. A new development by Corus looks to achieve an alternative method of refinement, using a high-density dispersion of fine rare earth sulphide particles to nucleate ferrite inside the austenite grains. An introduction to rare earth elements is given in this paper and the history of the development of their use is outlined. Details of the experimental work done by Corus are described, leading to a discussion on how a full-scale production trial might proceed, and the value of such a development to Corus as a company.
Dr. K.L. Lee Corus - Rods Technical Dept. Benefits of Boron treatment in medium carbon steel  
This paper aims to illustrate the influence of (unprotected) boron addition on the tensile strength, microstructure and drawability of medium carbon steel produced at Scunthorpe Rod Mill (SRM). The addition of boron has been found to provide significant improvements in the as-rolled rod tensile properties and microstructure. These improvements are due to boron initially combining with the free nitrogen, which improved the ductility, followed by the excess boron providing a marked increase in pearlite hardenability. This results in a microstructure containing a much lower fraction of ferrite and a finer pearlite than the conventional plain carbon steel. Customers’ feedback on the performance of boron treated grades has been very encouraging. They have reported that the boron treated steel showed superior drawability and mechanical properties compared to the conventional plain carbon steel during conversion to helical wire for bedding and seating applications.
