عنوان مقاله [English]
نویسنده [English]چکیده [English]
The aim of this work is to introduce the application of a rotary kiln system to be used in enamel industry for the purpose of melting lead silicate glass. Due to low volume of lead silicate glass produces during a day or a year, and the necessity to spend a large capital investment for using customary glass melting furnaces, it was decided to apply a rotary kiln system for melting lead silicate glass. In order to be assured for the high corrosion and temperature resistance, alumina refractories were used as a refractory for the inner lining of the rotary kiln. The lead silicate glass after melting and mixing inside the kiln and fritting was grinded inside a ball mill with alumina lining and balls to a powder of mesh size finer than 75 micron. The melting, fritting and milling were repeated 5 times. The results showed that there was neither entered any impurity from the refractory particles nor observed any color and composition change due to entrance of aluminum element to the lead silicate glass melt. The homogenization of the glass composition and the removal of the bubble from the glass melt was carried out extremely well.
