Abstract Scope |
The high-temperature physical performances of continuous casting billet are crucial for simulating the solidification heat transfer process. In this study, the high-temperature physical performances of 20CrMnTi billet were tesetd. Combining experimental test results, the solidification heat transfer process in the secondary cooling zone was simulated, obtaining surface temperature distribution and shell thickness variation of the billet. The results indicated that the solidus and liquidus temperatures of the 20CrMnTi billet were 1462 ℃ and 1505 ℃, respectively. Significant fluctuations in specific heat capacity and thermal conductivity were observed in the phase transition region. At the exit of mold, the billet shell thickness exceeded 15 mm, complying with metallurgical standards. At the beginning of straightening, the central temperature of the billet's surface was 1043 ℃, avoiding the high-temperature brittleness zone. |
