9th ECCC European Continuous Casting Conference – ECCC 2017

A Molten mold flux technology so called, POCAST process has been newly used to enhance the slab quality of Ultra Low Carbn Steel(0.001~0.002 C%). Due to the thicker slag layer and higher temperature of meniscus, POCAST technology can influence in many ways; shorten the hook length, decreased C-pickup on the slab surface, less inclusion within the slab, enhancing the slab lubrication and etc.. In this papaer, measures on slag entrapment behavior is introduced varies with molten slag layer using water model compared with commercial practice results.
