Identification of optimal mould lubrication conditions through an innovative hot and cold simulation method (LUBRIMOULD) : final report

The complex system consisting of a flux in a mould during steel continuous casting has been represented by a set of concepts and modelling tools. The concepts concern some aspect that are not usually considered for the choice of a mould flux such as the NBO/T index, whereas the modelling tools reproduce the occurring phenomena depending on process conditions and mould powder characteristics. This allows for identifying the proper casting parameters and flux properties to be used for optimising different steel casting. This set of tools has been verified on industrial fields. The results led to a decrease of the defects on casting products without affecting productivity. The proposed method has a general applicability as demonstrated by the wide range of steels and mould powders involved in the project.
