What Is the Use of Tungsten Wire in Steel Smelting?

The main use of tungsten wire in steel smelting is as an electrode material for electric arc furnaces. Specifically, it is used in electric arc furnaces to generate high-temperature arcs to heat scrap steel or raw materials to temperatures high enough for the melting and smelting process. Here are some of the key uses and characteristics of tungsten wire in steel smelting:

Electrode Materials: Tungsten wires are commonly used as electrodes in electric arc furnaces. These electrodes generate high temperatures through arc discharge to heat and melt metals. One of the reasons tungsten wire was chosen as the electrode material is its high melting point (approximately 3,422 degrees Celsius or 6,192 degrees Fahrenheit), which allows it to remain stable at extremely high temperatures.

High Temperature Stability: Tungsten wire performs well in electric arc furnaces due to its high melting point and resistance to oxidation. At high temperatures, tungsten wire does not melt or oxidize easily, making it ideal for smelting high-temperature metals.

Electrical conductivity: Tungsten wire has good electrical conductivity, which means it can effectively conduct electric current and produce a stable arc. This is important to maintain high temperature and efficient operation of the electric arc furnace.

Long life: Tungsten wire generally has a long service life, which is critical for continuously running smelting processes. Its resistance to wear and corrosion also helps extend its life.

Recyclability: Tungsten wire is a recyclable material, and used tungsten wire can be recycled and reused, helping to reduce resource waste.
