“…The reason for this phenomenon is due to the uneven flow of melt in the casting and rolling area. It is obvious that the flow of melt with certain viscosity in the casting and rolling zone is not only influenced by the pressure of the casting nozzle, but also by the rotation of the two sets of casting and rolling rolls [20]. The most intuitive manifestation of this is the vortex phenomenon in the casting zone [8,21].…”

Process of horizontal twin roll casting magnesium alloy was analyzed by numerical simulation. Taking solidification welding line in cast rolling area as research object, the characteristic change of solidification welding line caused by casting rolling temperature, casting rolling speed and roll heat transfer capacity and its influence on the forming process of casting rolling area were analyzed. The results show that increasing casting temperature, casting speed or reducing heat transfer capacity of roll can make solidification welding line shift to exit of casting rolling zone. Increasing casting temperature and casting speed will increase difference between middle and edge of the solidification welding line along casting direction. And heat distribution of whole slab is more uniform. However, effect of improving heat transfer capacity of roll is completely opposite. According to this, optimum process parameters of casting and rolling magnesium alloy with plate thickness of 6 mm are put forward to reduce probability of edge crack.

A 3D model of heat transfer between the circular‐distributed water channel roll (CDWCR) and slab during ultrathick slab continuous casting process is established, considering the structure of water channels inside CDWCR and rotating contact between the roll and slab. The results show that the contribution of conduction heat transfer in the heating process of the roll is greater than that of radiation heat transfer, and maximum surface temperature of the roll is 460 K, located at the place where it is right out of contact with the slab, and the change of internal temperature of the roll lags behind the change of surface temperature. The temperature decreases gradually from the outside to the inside in the radial direction. The temperature of the CDWCR inside the circle of cooling water channels is no more than 325 K. The yield strength of CDWCR is analyzed, showing that the strength of the roll meets the requirements of using it in the process. In addition, the orthogonal method is used to analyze the influence factors on CDWCR temperature. The results indicate that the orders of factors affecting more are the contact angle, the slab temperature, the casting speed, and the inlet speed of cooling water.
