9th ECCC European Continuous Casting Conference – ECCC 2017

Mold slag plays a very important role in continuous casting process. However, the understanding on the real behavior of the mold slag film in-between the steel shell and Cu mold is still not very clear in terms of controlling heat transfer and lubrication. The reason is the complexity of the slag film history along the mold and its coupling effect with the temperature and time. In this study, slag film samples were taken from the below meniscus area after casting of a number of steel grades. It is believed that the heat transfer through slag film is the most important factor in this area for casting process. Investigations are carried out in attempt to detail the observations which may provide important information in understanding the film behavior and shed lights in further mold slag development.
