Abstract Scope |
During the continuous casting of medium carbon steel, longitudinal cracks often occur, primarily caused by uneven heat transfer in 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 slag film thickness exhibited an initial decrease followed by a subsequent increase along the casting direction. Additionally, the total resistance Rtot、solid slag film resistance Rs、liquid slag film resistance Rl、interfacial resistance Rint all appear an initial decrease followed by a subsequent increase along the casting direction. Overall, Rtot is 12.72 × 10−4 m2·K/W at the location of shell tip, and decrease to the minimum value 7.78 × 10−4 m2·K/W at 5 mm below the shell tip, then it begins to increase and finally is 9.68 × 10−4 m2·K/W at 10 mm below the shell tip. |
