内容简介

The authors have developed a spherical shaped container having internal walls constructed with ceramic hollow units for transferring molten aluminuin. This newly designed container was expected to provide light weight and high heat retaining property. compared with current cylindrical containers having internal walls made of castable refractories. On the other hand, it was an important problem to suppress heat transmission caused by radiation and convection in the inside space of the unit. In this paper, heat transmission was successfully suppressed by applying ceramic fiber as light insulating materials or metal foil as low emissivity materials to inside units. Furthermore, design of the rear-face and pathway of heat transmission of units were also discussed. The evaluation of overall heat transfer coefficient of units revealed the structure which made it possible to combine high heat insulating property and light weight of units.
