Abstract Friction and non-uniform lubrication are the key factors affecting the quality of continuous casting billet. In view of the complex friction behavior of the billet in the mold, a full-scale heat transfer model and a friction calculation model were established, and the actual heat flow was obtained by using the inverse algorithm. The friction behavior of the billet was described in detail, and the factors affecting the friction were further studied.The results show that, starting from the meniscus, the surface of the slab transitions from liquid friction zone to mixed friction zone and then to solid friction zone. The friction state of billet is asymmetric, which reflects the necessity of establishing a full-scale model. The model provides a useful tool for understanding the complex process in the mold and optimizing the technological parameters of continuous casting.

Key words： continuous casting slab inverse algorithm friction mold flux finite-element
