The use of tungsten wire in glass heating is mainly as a heating element, using its high melting point, high temperature resistance and oxidation resistance to provide a high temperature and stable heat source to meet the needs of glass processing and treatment. The following are the specific applications of tungsten wire in glass heating:
1. Glass Melting
Tungsten wire heating can provide enough high temperature to melt the glass raw materials into liquid. This is the basic step in the production of various glass products (such as glass cups, glass plates, etc.).
2. Glass Molding
During the glass molding process, tungsten wire heating can accurately control the temperature and viscosity of the glass to make it suitable for shaping, which is convenient for manufacturing glass products of specific shapes.
3. Glass Heat Treatment
Tungsten wire heating can be used in glass heat treatment processes, such as annealing (slow cooling to reduce internal stress) or quenching (rapid cooling to enhance strength), thereby improving the physical properties of the glass.
4. Glass Welding
Tungsten wire heating can melt glass and is used for glass welding or repair, such as connecting glass parts or repairing broken parts.
5. Other Applications
In addition to the above uses, tungsten wire is also widely used in processes such as glass fiber drawing (pulling molten glass into filaments) and glass tube production, providing a stable high-temperature heat source for these processes.
