ABSTRACT:
A method and apparatus for melting low-cost raw materials such as blast furnace slag, basalt, feldspar or electrophos slag in the formation of high temperature mineral wool insulation. The low-cost mineral stock material is fed in particulate form continuously to a preheater in which it is elevated to a temperature range of between 1500.degree. F. and 2000.degree. F. by forcing hot combustion gases through a vertical column of the particulate stock material. Volatiles such as water and carbon dioxide are thus removed from the stock material. The preheated stock material is distributed to the top of an electric melting furnace which is essentially sealed from atmosphere. A substantially homogenous, low viscosity liquid glass melt is continuously discharged from the furnace.
