Tungsten bar high hardness and good wear resistance
1. The main raw materials for preparing tungsten steel rods are tungsten and steel, with a high purity requirement for tungsten. Firstly, high-purity tungsten powder needs to be selected, and then mixed evenly with an appropriate amount of steel powder in a certain proportion.
2. Mixing powder: tungsten powder and steel powder are mixed in a ball mill, and a certain amount of ball milling medium is added to mix the two powders thoroughly and evenly through ball milling.
3. Compression molding: Put the mixed powder into the mold for compression molding. Pressing is generally divided into two methods: cold pressing and hot pressing. Cold pressing is carried out at room temperature, with lower pressure; Hot pressing is carried out at high temperatures, with higher pressure. Hot pressing can increase the density of tungsten steel bars, but it also increases production costs.
4. Sintering treatment: Place the pressed tungsten steel rod into the sintering furnace for sintering treatment. During the sintering process, the powder particles will combine to form dense tungsten steel rods. The sintering temperature and time need to be adjusted according to specific circumstances to ensure the performance of tungsten steel bars.
5. The tungsten steel rod after precision machining and sintering needs to undergo precision machining, including turning, grinding, polishing and other processes, in order to achieve higher accuracy and smoothness. During precision machining, it is necessary to pay attention to controlling the machining temperature and cutting speed to avoid the impact of excessive temperature on the performance of tungsten steel bars.
1、 Electronic field
Tungsten rods, as electrode materials, are mainly used in high-voltage applications such as high-frequency electronic tubes, semiconductor devices, and electron beam equipment. In these application areas, tungsten rods can withstand high currents and temperatures, and are not easily ablated, making them an ideal electrode material.
2、 Aerospace field
Tungsten rods have the characteristics of high strength, high melting point, and high stability, so they have also been widely used in the aerospace field. In the manufacturing process of launching rockets, satellites and other spacecraft, tungsten rods are mainly used to manufacture high-temperature components such as engine nozzles and combustion chambers.
3、 Metallurgical field
Tungsten rods are also widely used in the metallurgical field, mainly for manufacturing materials such as high-speed steel and hard alloys. Tungsten rods can be used as additives for steel alloys, improving the mechanical and wear resistance of steel, as well as enhancing its hardness and toughness.
