Practical casting of 6063 alloy DC billets having complete feathery crystals

Abstract

6063 DC billets having complete feathery crystals are expected reducing the deformation resistance. Practical casting tests were made to produce such billets using an improved mold, float and water pool. The optimum casting variables to ensure the DC billets 152mm in diameter having complete feathery crystals are; casting rate 115mm/min, casting temperature 730°C and cooling water 120l/min.
