Abstract

Principle of foamed glass manufacturing process first starts with putting vitreous material powder into a mold. After the foaming calcination, foamed body should be annealed after separation from the mold. For this reason, existing manufacturing process could not be a continuous type process. In this study, in order to develop a continuous production process of foamed glass, the possibility of new foam glass manufacturing process was investigated by foaming calcination of the compact body obtained from compression-molding of vitreous raw materials in stead of using a mold. Through the experimental results of the foaming calcination of the compact body with adding various foaming agents such as $Na_2CO_3$, $CaCO_3$ and petroleum coke, into hydrated soda-lime vitreous raw materials, it was shown that developing a continuous process without using any molds for manufacturing foamed glass would be possible.
