One, raw material preparation
The production of tungsten wire requires high-purity tungsten powder, which is typically derived from the reduction of tungsten trioxide. During the reduction process, factors such as temperature, atmosphere, and the ratio of reductant must be controlled to achieve the desired grain size and chemical composition.
Sintering
The tungsten powder, meticulously proportioned, is mixed at a specific ratio and then combined with a certain amount of binder for shaping. Subsequently, sintering is carried out under high temperatures. During the sintering process, careful control of factors such as temperature, time, and atmosphere is essential to achieve high density and mechanical properties.
Section 3: Compression
Sintered tungsten billets are subjected to extrusion, which further optimizes their grain structure and enhances their overall performance. Surface treatment must be conducted prior to extrusion, along with pre-treatment and heating as required.
Four: Wrought wire
Wolfram billets, after being extruded into shape, undergo wire drawing, which can be done through CNC wire drawing or traditional wire drawing methods. During the drawing process, the diameter can be gradually reduced to achieve the desired size and fineness. Additionally, a certain amount of lubricant must be added during the drawing to minimize heat loss and breakage of the wolfram wire.
V. Key Technologies and Equipment
The production of tungsten wire requires a series of equipment and technologies, such as ball mills, ultrasonic disassemblers, high-temperature sintering furnaces, extruders, and drawing machines. Additionally, factors like raw material quality, preparation processes, and production environment must also be considered.
In summary, the production of tungsten wire is a complex process that requires the coordination of various technologies and equipment. High-quality tungsten wire products can only be achieved when both the technology and equipment reach a certain level.
