General Introduction for Molten Steel Disposable Thermocouple Tip
Disposable Thermocouple is used to measure the temperature of
molten steel and high temperature molten metal, and it is a
one-time consumption.The working principle is based on metal
thermoelectric effect,making use of the temperature difference from
both ends for the temperature measurement of molten steel and

Structure for Molten Steel Disposable Thermocouple Tip
Fast thermocouple structure, it is mainly composed of measuring tip
and paper tube. The positive and negative wire is weldied with the
compensation wire,which is embedded on the the bracket,which is
coated with paper tube. Also there is quartz support and protection
for the thermocouplepositive and negative wire.The outside with the
slag cap, all components in the head and with refractory filler
glue into a whole, and sealed, so for one-time use.
Using Method for Molten Steel Disposable Thermocouple Tip
1, According to the measured object, selecting the appropriate
protection tube length and suitable temperature measuring gun.
2, put the fast thermocouple on the temperature measuring gun, and
let the digital meter back to zero, if it shows good contacts at
this moment, then can be measured.
3, Disposable Thermocouple insertion depth of the molten steel with
300-400 - mm advisable, don't contact furnace wall.
When get the temperature,get back the gun,if too long time,the gun
will be burnt out.
4, After getting the temperature,remove the tip and install a new
one, and pause for a few minutes.Do not measure it continuously,
otherwise there will be fluctuations.
