Abstract

For good quality billet, metal degasing is important consideration in billet casting. In-line degasser processes help to remove 61 to 66% of the dissolved gas. An improved billet quality can increase extrusion speed. A model of degassing delineates the most important key factors for optimization of product design for high quality, productivity and cost savings using computer simulations. The present work focuses on aluminum direct chilled casting process with gas injected in the mold through a submerged entry nozzle. The effects of gas into the melt and a direct casting magnetic field on the mold fluid flow are studied. Considering the effect of complex flow, injection and heat transfer on the gas bubble size the particles model reveals to be an efficient method to study the degassing phenomenon. However, the model treats the gaseous phase as bubbles with multiple sizes providing a new approach to simulate multiphase flow in continuous casting.
