The production of tungsten wire does involve high-temperature furnaces. High temperature furnace plays a vital role in the production process of tungsten wire for the following reasons:
- The role of high temperature furnace
Provide high temperature environment: The production of tungsten wire needs to be carried out in a high temperature environment. The high temperature furnace can provide the required high temperature environment to meet the process requirements of tungsten wire production.
Heat treatment: In the high temperature furnace, tungsten wire can undergo heat treatment processes such as heating and sintering to improve its density, ductility and strength.
- Production process of tungsten wire
Raw material preparation: First, prepare tungsten blanks as raw materials. Tungsten blanks need to be chemically treated to remove impurities.
Heating treatment: Put the tungsten blanks into a high temperature furnace and heat them to reach the temperature required for making tungsten wire. At high temperatures, the tungsten blanks will undergo a series of physical and chemical changes, such as melting, recrystallization, etc., to form tungsten wire.
Subsequent processing: After heating treatment in a high temperature furnace, the tungsten wire also needs to undergo subsequent processing and treatment, such as drawing, polishing, etc., to further improve its quality and performance.
- Types and requirements of high temperature furnaces
Types: There are many types of high temperature furnaces, such as vacuum high temperature furnaces, atmosphere high temperature furnaces, etc. Different types of high temperature furnaces are suitable for different tungsten wire production processes.
Requirements: The high temperature furnace needs to have good sealing and high temperature stability to ensure that the tungsten wire will not be oxidized or contaminated during the heating process. At the same time, the heating speed and temperature control of the high temperature furnace also need to be precisely controlled to meet the process requirements of tungsten wire production.
