High Stable Electric Glass Furnace Manufacturer from China
1. Brief Description
Glass was used for windows and doors by the Ancient Romans as early
as the 4th century.
In 1902, Voelker was granted a basic patent for melting glass using
the heat generated by an electric current through the batched
material. Under the continuous development and improvement of the
furnace design technology and electrode, this electric melting
method is extensively used.
Between the year 1920 to 1925, Raeder from Norway used graphite
electrode for furnace, which has successfully achieved a fully
electric furnace.
In 1925, Corneljus from Sweden took this kind of electric furnace to produce amber glass and green glass. The electric melting furnace adopts the method of blanket charging and the batching material floats on the surface of glass liquid
Glass is an electric conductor under high temperature. There are alkali metal and potassium ions in melted glass liquid. These two ions have conductivity, when the electricity through the glass liquid, the joule heat will be produced, if there is enough calories produced, it can melt the glass, which is called “Glass Electric Melting”.

Using cooling top vertical melting type theory, which will
concentrate the melting process. The design of melting area is
benefited for glass melting and homogenization, no death zone in
melting scope, that will ensure the melting efficiency of glass
materials and clarification, producing high quality glass liquid.
Adopt electric fused cast AZS materials for melting and non-melting
areas, clay brick, light clay insulation brick and aluminum
silicate products for other parts.
