Abstract

 Production of large diameter aluminum billets with minimum defects is one of main goals of researchers in the relevant industries. In the current paper a model has been developed to simulate DIRECT CHILL CASTING in the presence of low frequency ELECTROMAGNETIC fields. The model was verified using the results of temperature and magnetic field measurements. The results of solving of thermal, velocity, and pressure field as well as magnetic field with SOLIDIFICATION approach showed that using of a simple coil back of the mold causes to push the melt to the center of billet. Also, parametric studies on this process illustrated frequency decrease and increase of ELECTROMAGNETIC intensity results in more uniform distribution of ELECTROMAGNETIC force and more severe agitation of the melt, respectively. Setting up the ELECTROMAGNETIC parameters in an appropriate range can improve surface quality and microstructure of the bulk near the surface of the LARGE DIAMETER BILLET. However there are slight modifications in the center of bilet.
