9th ECCC European Continuous Casting Conference – ECCC 2017

Primetals Technologies provides proper technological solutions for the revamp of long product casters, and the most recent examples for successful implementation at Feralpi (EFS) and at Abinsk (AEMZ) are presented in this paper, showing the qualitative results that can be achieved within shortest project execution time. Elbe-Stahlwerke Feralpi (EFS) in Riesa, Germany awarded PT with a...

In order to decrease the mould level fluctuation the casting parameters such as casting speed, mould powder and oscillation type have to be optimized. The general full factorial design of experiments were successfully carried out two times. In these experiments two different mould powder and sinusoidal/non-sinusoidal oscillation types from high to low casting speeds were investigated in-situ...

Atypical secondary oscillation marks (SOM), and related transversal surface cracks, have been detected on the billet surface between two consecutive primary oscillation marks, when casting with abnormal oscillation settings in Curve Continuous Casting (CCC). The study of the obtained near surface solidification microstructure under this conditions have shown similarities with the...

In actual steel continuous casting process, the spraying water in secondary cooling zone always distributes non-uniformly, especially across the width direction of the steel bloom/billet. However, it is generally assumed that the cooling pattern of secondary cooling zone is uniform in many traditional heat transfer models, which will surely result in obvious calculation errors. In this paper,...
