Yes, the production of cleaned tungsten wire requires high-temperature environments, specifically in the following steps:
- Reduction: Approximately 800–1000°C to reduce WO₃ to tungsten powder.
- Sintering: Approximately 2500–3000°C to densify the tungsten blank.
- Swaging: Approximately 1400–1600°C to improve the plasticity of the tungsten rod.
- Drawing and Annealing: Partial hot drawing at about 1000–1200°C, with annealing requiring similar temperatures.
- Heat Treatment: Final annealing or stress relief at about 1000–2000°C.
High-temperature environments must be precisely controlled to ensure tungsten performance and prevent abnormal grain growth due to overheating.
