Abstract

Three options for tuyere nose cores are commonly available when casting: sand, copper and glass. This paper investigates the effects of core type on tuyere manufacture and operating performance. A combination of mechanical testing and computational fluid dynamics is used to evaluate the impact of nose core type on cooling efficiency. Surface roughness is shown to be the major factor in cooling efficiency. Sand cores show a surface roughness of 323 RMS compared to 102 RMS when using a glass core, which directly affects boundary layer formation and pressure drop. Radiographic images of the castings identify poor adhesion to copper pipe cores.
