In response to the problem of tungsten wire fracture due to sudden temperature changes, the following coping strategies can be adopted:
- Material selection and optimization
Improve the purity of tungsten wire:
Select high-purity tungsten wire materials and reduce the impurity content to improve the thermal shock resistance and toughness of tungsten wire.
Adopt composite materials:
By adding other metal or non-metal elements to tungsten wire to form composite materials, the thermophysical and mechanical properties of tungsten wire can be improved, and its ability to resist sudden temperature changes can be improved.
- Design and process improvement
Optimize structural design:
Reasonably design the shape, size and layout of the tungsten wire to reduce the thermal stress and mechanical stress concentration caused by sudden temperature changes.
Improve manufacturing process:
Adopt advanced manufacturing processes such as precision casting, forging, heat treatment, etc. to optimize the microstructure and performance of the tungsten wire and improve its fracture resistance.
- Temperature control and management
Temperature gradient control:
During the working process of the tungsten wire, try to achieve a smooth transition of temperature and avoid sharp temperature changes.
The temperature change rate can be controlled by adjusting parameters such as heating rate and cooling rate.
Temperature monitoring and early warning:
Install temperature sensors and monitoring equipment in the working environment of the tungsten wire to monitor temperature changes in real time.
When the temperature is abnormal, issue an early warning in time and take corresponding measures to avoid the tungsten wire from breaking due to sudden temperature changes.
- Enhance protection measures
Heat shielding and insulation:
Set a heat shielding layer or insulation material around the tungsten wire to reduce the impact of external temperature changes on the tungsten wire.
Stress relief structure:
Add stress relief structures such as elastic elements and buffer layers to the design of tungsten wire to absorb and disperse the stress generated by sudden temperature changes.
- Maintenance and care
Regular inspection and maintenance:
Inspect the tungsten wire regularly to detect and deal with potential defects and damage in time.
Replace or repair the aged tungsten wire to ensure its normal operation.
Optimize the use environment:
Keep the working environment of the tungsten wire clean and dry to avoid the influence of pollutants such as dust and moisture on the tungsten wire.
At the same time, ensure that the temperature and humidity of the working environment are within a suitable range to reduce the possibility of sudden temperature changes.
