Strategies for Optimizing Tungsten Rod Heating Efficiency

In terms of optimizing the heating efficiency of tungsten rods, the following aspects can be considered:
Using advanced sintering equipment:
Introducing a horizontal tungsten rod intermediate frequency sintering device, which supports the tungsten rod through tungsten support bars, effectively eliminating the defect of sintering bending, and protecting the gas from flowing upwards from the bottom to ensure uniform heating dispersion.
This device uses the heating coil connected to the IGBT intermediate frequency power supply to generate eddy currents to heat the tungsten rod, ensuring the uniformity of the temperature range in the sintering unit, and making the composition/microstructure and density of the tungsten rod uniform during the sintering process.
This device also increases the one-time loading capacity of tungsten rods through the design of multi-layer tungsten support bars, ensuring that tungsten rods sintered in the same furnace have consistent uniformity, thereby greatly improving heating efficiency.
Optimize sintering process parameters:

A method for improving the thermal conductivity of tungsten copper alloys was mentioned, which includes steps of ultra-high pressure heat treatment and aging treatment. These steps can be further applied to the sintering process of tungsten rods by optimizing parameters such as temperature, pressure, and time.
Especially, ultra-high pressure heat treatment (3.0-5.0 GPa, 820-900 ℃) and aging treatment (450-550 ℃, 90-120 minutes) can be adjusted according to the characteristics of tungsten rods to improve their thermal conductivity and heating efficiency.
Choose appropriate forming agents and preparation processes:
Using induced copper and stearic acid as forming agents can improve the formability of tungsten powder and produce high-quality tungsten copper composite materials. The use of these forming agents and the optimization of preparation processes can also be applied to the preparation process of tungsten rods.
By optimizing the types and amounts of forming agents, as well as process parameters such as pressing and infiltration, the density and uniformity of tungsten rods can be improved, thereby improving their heating efficiency.
Control sintering environment:
Ensuring atmosphere control during sintering, such as nitrogen protection, can prevent oxidation or other chemical reactions of tungsten rods during heating, maintaining their purity and performance.
Meanwhile, controlling factors such as temperature gradient, pressure variation, and airflow velocity in the sintering environment can further optimize the heating efficiency and performance of tungsten rods.
Introducing advanced heating technology and equipment:
Continuously exploring and introducing new heating technologies and equipment, such as laser heating, microwave heating, etc., can provide a more efficient and uniform energy input method for the heating process of tungsten rods.
These new technologies and equipment can be combined with traditional sintering processes to form a more advanced and efficient tungsten rod heating and sintering process system.
In summary, strategies for optimizing the heating efficiency of tungsten rods include using advanced sintering devices, optimizing sintering process parameters, selecting appropriate forming agents and preparation processes, controlling the sintering environment, and introducing advanced heating technologies and equipment. By comprehensively applying these strategies, the heating efficiency and performance of tungsten rods can be significantly improved, providing higher quality and more reliable tungsten rod products for applications in related fields.
