1. Material preparation
(Selected high-purity tungsten powder)
2. Smelt
(Put tungsten powder into the melting furnace for high-temperature melting)
3. Pouring
(Pour the molten tungsten liquid into the pre prepared mold and let it cool and solidify)
4. Heat treatment

5. Surface treatment
(Including cutting, grinding, polishing and other processes)
1. Application of tungsten rods in the mining industry: Due to their excellent wear resistance and tensile strength, tungsten rods are widely used in milling cutters, gears, bearings, and other excavation mechanisms in the mining industry.
2. Application of tungsten rods in the aerospace field: Tungsten rods have important applications in the aerospace field, mainly used in the manufacturing of high-temperature, high-pressure compressors and other components, as well as as as reflector materials for aircraft.
3. Application of tungsten rods in the field of electronics: Due to their excellent conductivity and thermal stability, tungsten rods also have important applications in the field of electronics. Tungsten rods can be used to manufacture semiconductor materials, electrodes, and emitters.
1. Thermal stress: When a tungsten rod is heated to high temperatures, it is subject to thermal stress, which may cause it to bend or warp. This can happen if the rod is not properly supported or is subjected to rapid temperature changes.
2. Material fatigue: Tungsten rods will experience material fatigue after being used at high temperatures for a long time. This can cause the material to weaken, making it easier to bend or warp.
3. Insufficient cooling: If the tungsten rod is not properly cooled after use, heat may be retained and continue to deform during the cooling process, resulting in bending.
4. Mechanical damage: If the tungsten rod is subjected to mechanical stress or impact during use, micro-cracks or other structural damage may occur, resulting in bending after burning.
1. Choose the appropriate tungsten rod
Choose appropriate materials and specifications when using tungsten rods. Different application scenarios require the use of different specifications and lengths of tungsten rods.
2. Control heating temperature
When heating tungsten rods, it is important to control the temperature and pay attention to the heating time to avoid excessively high temperatures or long heating times.
3. Avoid excessive stretching
When using tungsten rods, excessive stretching should be avoided, and changing the welding method or other processing techniques can be considered.
