A review of the manufacture, processing, and use of rail steels in North America: A report of aisi technical subcommittee on rails and accessories

Abstract: The intent of this, the initial paper of this publication, is generally to set the stage for the more specific and detailed state-of-the-art papers to follow. The evolution of the North American tee rail in its struggle to "keep its head" under progressively heavier and faster-moving motive power and rolling stock is traced briefly. Technological developments in rail steel and rail production designed to improve quality and enhance resistance to service developments are reviewed. This includes adaptation of various steelmaking processes and grades of steel to the production of rails, and the handling of the steel through the forming, cooling, finishing, and in some cases further treatment of the'rails.

Turbulent flow in concentric annuli

Abstract: An eddy diffusivity model was developed and used to predict velocity distributions for turbulent flow of air in annuli. Comparison of distributions calculated by the model with experimental data shows that good agreement between calculated and measured values can be attained for core-to-shell ratios from 0.001 to 0.990. The significant advantage of using a diffusivity model to predict velocity distributions lies in the inherent ability to consider systems with nonlinear stress distributions.

Fiber optic sensor and method of use thereof to determine carbon content of molten steel contained in a basic oxygen furnace

Abstract: The invention is directed to a gas cooled fiber-optic cable apparatus for use in a hostile environment, for instance adjacent a metallurgical furnace, and a method using the apparatus to determine carbon content of molten steel. The fiber-optic cable includes a radiation collection end comprising a manifold chamber that surrounds the fiber-optic cable filaments used to collect radiant energy emitted from the furnace flame. The manifold includes a tip portion having an orifice to expose the filaments to the radiant energy, and a gas supply attached to the manifold to inject a cooling gas into the chamber. The orifice provides a discharge for expelling the cooling gas from the manifold chamber at a high velocity purge to prevent foreign matter from entering the chamber. The gas cooled fiber-optic cable transmits collected radiant energy to a radiation sensor. The sensor converts the energy into voltage signals and the signal information is processed to determine carbon content of steel contained in the metallurgical furnace.
