Computational fluid dynamic simulations of solidification for enhancing speed of continuous cast copper

In this research experiment computational fluid dynamic (CFD) models were constructed, within Ansys Fluent TM v.R1, to investigate phenomena occurring during the Vertically Upwards Continuous Casting (VUCC) of 8 mm diameter, oxygen free copper (OFCu) for alterations casting speed. The simulated influence heat transported over a 0.1 air gap formed die was investigated and value wall transfer coefficient (hc) (9.0 ± 0.2) × 104 W/m2K, extracted. Using hc, simulations entire crucible made speed settings: pushback motion at 0.06 m/s, average; dwell (pause) 0.05 continuous motions 0.022 0.015 m/s 0.008 m/s; validated against literature values measured thermal distribution die. fastest OFCu trend between solidification front grain growth direction identified, highlighting, yield improved conditions. Fluid flow rate showed small on due natural convection relative die, 0.001 0.0005 compared with 0.01 casting, respectively.
