Today, producing speciality glasses requires a glass furnace with accurate temperature capability. Glass furnaces are energy-intensive and play a crucial role in glass manufacturing. The glass melting furnaces are designed to melt raw materials into glass. The glass melters can be electric, gas-fired, or oil-fired. Glass Melting Technology is an effective way for glass production enterprises to improve product quality, reduce energy consumption and fundamentally eliminate environmental pollution.
In recent years, electric glass furnaces have been used more. These furnaces have become part of a new business strategy in glass manufacturing. Electric glass melters are used for fibreglass production but are also used for speciality glasses.
These electric furnaces offer high thermal efficiency and a high degree of control over temperature. They can yield highly homogeneous glass while minimising atmospheric pollution and economising raw materials that volatilise readily. The industries and manufacturing plants that use glass furnaces include bottle makers, window producers and cookware companies. Apart from these, other industries using glass furnaces are Aerospace, Medical and Electronics.
Tunnel Furnace is an industrial furnace used for continuously heating, annealing, and sintering materials. It is designed as a long, narrow tunnel with a conveyor system that carries the materials through the furnace. It is essential for various industries, including metalworking, ceramics, and glass production. The tunnel furnaces provide uniform heating and cooling of materials, making them crucial in manufacturing. The tunnel furnace includes Uncoiler, Shear, welder, loopers, degreasing unit, annealing unit, driving machines, control system and other auxiliary equipment. These furnaces provide several benefits, including precise temperature control, uniform heating, energy efficiency and continuous operation.
Use of Glass Melters
A glass melting furnace is a furnace that melts raw materials to make glass, and there are various designs of glass melting furnaces depending on the application. Some of the products made using glass melters include:
- Jars
- Bottles
- Glass Panes
- Lab Equipment
- Lenses
- Cookware.
Significance of Electric Melting of Glass
An electric glass melter is a furnace in which all the heat required for melting is provided by electric current from electrodes submerged in the molten glass. The electric glass melter consumes most of the electrical power during the melting process. Electric glass melting furnaces are used for speciality glasses, such as fluoride opal glasses, borosilicates and lead crystal.
Some of the main benefits of Electric Glass Melters include:
- The thermal efficiency of glass electric melting is much higher than that of flame-melting furnaces.
- The electric melting furnace has a simple structure, small floor space, stable control and easy operation.
- Reduces noise, stabilises the melting process, improves product Quality, etc.
- No combustion-related CO2, thermal NOx or SOx emissions are released.
- These furnaces are more energy efficient than gas-fired furnaces; they use around 35% less energy.
- Reduce volatilisation of volatile compound components.
Lastly, all-electric Melters are the lower-cost option for smaller melting capacities. It is in addition to the glass quality and environmental benefits of cold-top electric melting for high-quality or volatile glasses.
Significance of a Tunnel Furnace
The Tunnel Furnace is designed and manufactured with foreign advanced Technology, with advanced structure, easy disassembly and assembly, and a beautiful appearance. It provides high temperatures, which is enough to melt most metals. These furnaces process various materials, including ceramics, glass, metals, and plastics. The stove provides excellent temperature uniformity while maintaining consistent production. Tunnel furnaces use less energy than traditional furnaces, reducing operating costs. These furnaces also have advanced control systems that allow for precise temperature and atmosphere control, further improving energy efficiency. Also, these furnaces can handle various materials and product shapes, including long and flat items.
