Abstract Scope |
During the continuous casting of medium carbon steel, longitudinal cracks often occur, primarily caused by uneven heat transfer in the slag film at meniscus between the mold and shell. This study investigated the heat transfer behavior of the slag film at meniscus using a mold simulator technique. The results showed the heat flux of the mold exhibited an initial increase followed by a subsequent decrease along the casting direction, while the surface temperature of the shell decreased. The thickness of the slag film showed a decreasing trend along the casting direction. Overall, the slag film thickness ranged from 3.45 to 1.98 mm from the shell tip to 10 mm below the shell tip. Additionally, the total resistance Rtot、solid slag film resistance Rs、liquid slag film resistance Rl、interfacial resistance Rint all appeared an initial decrease followed by a subsequent increase along the casting direction. |
