Application of tungsten-rhenium thermocouple
1. Metallurgical industry, powder metallurgy
P/M products are usually produced in reductive atmosphere such as H2, operating temperature 1000~1800℃. Using corundum tube or sintered rigid tube, materialized anti - oxidation tungsten - rhenium thermocouple plays a very important role in it.
2. Production of vanadium nitrogen, manganese nitrogen, chromium nitrogen alloy boron carbide and Si3N4 powder
At present, regarding the production of vanadium nitrogen, chromium nitrogen alloy, manganese nitrogen alloy and Si3N4 powder production process control, more solid anti-oxide tungsten rhenium thermocouple.
3. Non-ferrous metallurgy
In the process of lead smelting, in order to make the lead slag can be separated well, the new technology of electric heating front bed is often used. The sensor must be in high temperature and strong corrosive medium. The detection environment is extremely harsh, resulting in a very short service life of platinum-rhodium thermocouple (only about 2 weeks), solid anti-oxidation tungsten-rhenium thermocouple can not only replace the expensive platinum-rhodium thermocouple, but also increase the service life times.
4, materialized anti-oxide tungsten rhenium thermocouple
Tungsten - rhenium thermocouple was used to replace platinum-rhodium couple in high temperature cracking furnace in chemical plant. In reducing atmosphere of 1400℃, composite corundum tube was used to obtain good results.
5, 1800℃-2000℃ high temperature
At the temperature above 1800℃, only tungsten - rhenium thermocouple is used at present. Tungsten-rhenium thermocouples have been successfully used in vacuum furnaces at 1800℃-2000℃.
6. Liquid steel temperature measurement
In order to meet the needs of vacuum metallurgy production process, the temperature of molten steel is measured online by means of cermet protective tube tungsten-rhenium thermocouple.
