Production Process for Pure Tungsten Particles

1. Raw Material Selection and Processing

• Raw Material Selection: High-purity tungsten powder is selected as the main raw material, ensuring its purity and particle size meet requirements.

• Raw Material Processing: The tungsten raw material is dried, sieved, and impurities are removed to prepare it for further processing.

2. Melting and Casting

• Melting: The tungsten powder is melted into a tungsten liquid at high temperatures, with the melting temperature and time being carefully controlled to ensure the quality of the tungsten liquid.

• Casting: The tungsten liquid is poured into a mold and cooled to solidify, forming a tungsten ingot.

3. Crushing and Milling

• Crushing: The tungsten ingot is crushed into smaller pieces using equipment such as jaw crushers, impact crushers, or hammer crushers.

• Milling: The crushed tungsten pieces are milled into tungsten powder, ensuring that the particle size distribution meets requirements.

4. Shaping and Sintering

• Shaping: The tungsten powder is pressed into the desired shape of tungsten particles.

• Sintering: The tungsten particles are sintered at high temperatures to densify and increase their strength. This step requires precise control of sintering temperature and time, as well as the use of an appropriate sintering atmosphere to avoid deformation and shrinkage during sintering.

5. Surface Treatment

The tungsten particles undergo surface treatment to improve their corrosion resistance and wear resistance. Common surface treatment methods include polishing and electroplating.

6. Inspection and Screening

• Inspection: The tungsten particles are inspected for size, shape, weight, density, and hardness to ensure they meet quality requirements.

• Screening: The tungsten particles are further screened to select those that meet the requirements.

Alternative Production Processes (Using Other Raw Materials)

If spherical ammonium tungstate is used as the raw material, the production process may include:

• Calcination: Spherical ammonium tungstate is calcined at high temperatures for several hours to prepare tungsten oxide.

• Reduction: The tungsten oxide is reduced in a hydrogen atmosphere to form metallic tungsten.

• Ball Milling: The reduced product is ball-milled to eliminate agglomeration and lumping during the reduction process, obtaining uniformly dispersed spherical tungsten particles.

• Screening: The ball-milled tungsten particles are screened to obtain high-purity tungsten particles.

Equipment Utilization

• Furnace: Used for melting tungsten powder at high temperatures to form tungsten liquid.

• Crusher: Used for crushing tungsten ingots into smaller pieces for subsequent milling.

• Milling Machine (typically used in metalworking, but may not be necessary in tungsten particle production): If more complex shaping of tungsten particles is required, milling machines or other metalworking equipment may be used. However, in the production of pure tungsten particles, the use of milling machines is not necessary as the shape of the tungsten particles is typically achieved through pressing and shaping.
