Main applications of Zhenan tungsten tube products
Tungsten tubes are mainly used in high-temperature furnaces, such as thermocouple protection tubes, sapphire single crystal furnaces, and supports in high-temperature sintering furnaces.
In quartz continuous melting furnaces, tungsten tubes are one of the key components, and together with tungsten material tables, tungsten core rods, and tungsten formers, they constitute the four key components in the furnace.
Due to the high temperature resistance and low pollution characteristics of tungsten, tungsten tubes are also widely used in the production of crucibles and accessories for ruby and sapphire crystal growth and rare earth smelting in the LED industry.
