The production of black tungsten wire involves several types of equipment, covering the entire process from tungsten ore processing to wire forming. The main equipment includes:
Raw Material Preparation Equipment:
- Crushers and Mills: Used to crush and grind tungsten ore (e.g., wolframite) into fine particles suitable for chemical processing, producing tungsten concentrate.
- Flotation Equipment: Separates black tungsten concentrate from the ore through a flotation process.
- Roasting Furnace: Roasts tungsten concentrate to convert it into tungsten trioxide (WO₃).
Chemical Processing Equipment:
- Dissolution Reactor: Dissolves tungsten trioxide in ammonia solution to produce ammonium paratungstate (APT) solution.
- Crystallization Equipment: Extracts high-purity ammonium paratungstate through evaporation or cooling crystallization.
- Reduction Furnace: Reduces ammonium paratungstate or tungsten trioxide into metallic tungsten powder, typically using a hydrogen reduction process.
Powder Metallurgy Equipment:
- Mixing Machine: Mixes tungsten powder with additives (e.g., dopants) to ensure uniformity.
- Press Machine: Compresses tungsten powder into tungsten billets (tungsten rods).
- Sintering Furnace: Sinters tungsten billets at high temperatures to densify them, forming tungsten rods with sufficient strength.
Wire Drawing Equipment:
- Wire Drawing Machine: The core equipment, used to draw sintered tungsten rods through multiple passes to gradually reduce their diameter, producing tungsten wire. Includes machines for coarse, medium, and fine drawing.
- Heating Furnace: Used during the drawing process for annealing to relieve internal stresses in the tungsten wire and improve ductility.
- Lubrication System: Provides lubrication during wire drawing to reduce die wear and improve the surface quality of the tungsten wire.
Auxiliary Equipment:
- Cleaning Equipment: Cleans the tungsten wire to remove residual lubricants or impurities from the surface.
- Testing Equipment: Includes microscopes, tensile testing machines, and resistance testers to measure the wire’s dimensions, mechanical properties, and electrical performance.
- Winding Machine: Winds the finished tungsten wire into coils for easy storage and transportation.
