COMBINING NUMERICAL SIMULATION WITH EXPERIMENTAL STUDY FOR CONTINUOUS CASTING PROCESS DESIGN

In order to improve design efficiency and reduce design cost, a new method combining numerical simulation with experimental verification was proposed in this study Firstly, controllable process parameters such as continuous casting speed and cooling water flow rate, are robustly designed according to the numerical simulation results of flow field, process experiments were subsequently done on a newly developed continuous casting machine of lead slice, the robust optimal design for the continuous casting process were gained at last. The results show that the cooling water flow significantly affects axial thickness of lead slice, while the casting speed determines mainly its circumferential thickness. When the casting speed is between 280L/min and 320L/min, and the cooling water flow rate is between 950r/min and 1100r/min at the same time, the axial thickness and circumferential thickness can been kept respectively 1.0 +/- 0.03mm and 1.0 +/- 0.1mm,which meet the robust design requirements.
