Tslab parinktys, Navigacija Turinys New secondary cooling patterns for peritectic and microalloyed steel ES leidiniai Tslab parinktys metaduomenys This project is aimed at investigating the surface quality improvement achievable by a fine grain size and small grain boundary precipitate within the surface and sub-surface regions by use of an reuters parinktys secondary cooling practice when casting aluminium grain refined and microalloyed peritectic steel grades.
A tslab parinktys designed intense cooling unit for the intermediate thickness slab Rodyti daugiau caster at Corus Tuscaloosa has allowed optimisation of the operating conditions and tslab parinktys improvement of both as-cast tslab parinktys rolled product surface quality was notes.
Limited work with an intense secondary tslab parinktys was performed for Bloom at Scunthorpe while laboratory and pilot plant studies have demonstrated that an intense secondary tslab parinktys to increase the amount of grain boundary ferrite requires a casting speed around 0.
CRM has worked on a metallurgical study of the hot ductility improvement achievable by a grain refining treatment and numerical modelling indicates tslab parinktys the feasibility is rather limited as it should combine a quenching to tslab parinktys least °C of 10 mm of the product, a reheating of this outer layer, and a progressive decrease of this layer to reach °C before unbending. Voest-Alpine Donawitz has worked at modifying the casting parameters superheat, casting rate, casting powder, primary cooling and secondary tslab parinktys strategies for avoiding surface and subsurface cracks on the CC3 bloom caster by means of SSCT tests, temperature measurement in the primary and secondary cooling zones and a numeric model.
