High-Precision Numerical Simulation for Effect of Casting Speed on Solidification of 40cr During Continuous Billet Casting
METALLURGIA ITALIANA(2015)
摘要
In order to study the effects of casting speed on the solidification process and optimize the process to reduce defects, a high-precision simulation model of solidification and heat transfer of square billet based on nailing test and temperature measurement is presented. The experiments have proven that values calculated by the model fit well the measured values and the relative error is maintained less than 2%. Some new rules about the relationships among casting speed, solidification end point and shell thickness are proposed in the paper for the first time.
