High Quality Electricial Heating Type Electric Glass Furnace
1. Brief Description
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
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
During World War II, Borel from Swiss did plenty of research and
development in electrodes, due to a shortage of fuel, he has done
successful work in this territory and his research results have
been promoted by a French company St. Gobain.
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
2. Advantages of the electric melting:
- High thermal efficiency, up to 80%~85%
- More energy saving
- Small footprint
- Simple structure
- Reduce the volatilization of expensive oxide in raw materials
- Stable melting technology
- No pollution
- Lower noise level
- Improved working condition
- Homogenized glass liquid
- High product quality
- Automatic control
- Less maintenance cost

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.
