Single Disposable Thermocouple structure: disposable consumption thermocouple is mainly composed of Single Disposable Thermocouple and large paper tube. The positive and negative thermocouple tip wires are welding on the compensation wires, while the compensation wires wear in the bracket. The bracket jacket is protected by small paper tube, and the thermocouple wires are supported and protected by to quartz tube. The thermocouple tips are protected by the anti-slag cap. All the components are concentrated into the mud and bonded together refractory fillers. It is not removable and reusable. Rapid temperature thermocouple for measuring molten steel and high temperature molten metal temperature, is a one-time consumption of thermocouple. Its working principle is based on the thermoelectric effect of metal, the use of thermocouple at both ends of the temperature difference between the measured temperature of molten steel and high melting metal temperature. First, according to the measurement of the object and scope, select the appropriate protection of the length of the paper tube and the applicable temperature lance. Second, the fast thermocouple installed on the thermometer, and the second instrument pointer (or digital display) back to zero, then the contact is good, can be measured. Third, the rapid thermocouple inserted into the depth of the molten steel to 300-400mm is appropriate, the measurement should not be measured to the furnace wall or slag, remember: fast, stable, accurate, when the second instrument gets results, temperature lance should be taken out immediately. Thermocouple in the molten steel immersion time shall not exceed 5 seconds, or easy to burn the temperature lance. Fourth, the thermometer from the furnace after the proposed removal of the used thermocouple, and put on a new, pause for a few minutes, ready for the next measurement. Do not measure too frequently, or easily cause temperature fluctuations. Fifth, transport and storage products in the handling should be careful when the transport process, shall not be damp, the product should be stored in the relative temperature of not more than 80%. Air circulation, does not contain the product caused by corrosion of harmful gases, and the whole carton of thermocouple shall be placed in the dry place in the warehouse.

1. Thermocouple is measuring the thermoelectric power to achieve temperature measurement. The main part of thermocouple is thermocouple head, which is composed of two different kinds of metal materials. The thermocouple head is constituted by the compensation wire, U type quartz tube, plastic stent, high temperature mud head, protective cap and paper tube body. Although it is a consumption type product, its performance will directly affect the quality of the product to be measured. Therefore the production of thermocouple, component quality, welding, installation, technical inspection, inventory storage requirements are very strict. 2. When using the thermocouple, it is only needed by connecting the melt gun with thermocouple, and insert the gun into the high temperature molten metal artificially or mechanically. The thermoelectric will be transferred to the intelligent display device, and we can get the melt temperature. 3. Consumption type thermocouple (temperature probe), is for the steel-making process (including electric furnace, converter, refining furnace, LF furnace, oxygen station, ladle, ladle, tundish) in the measurement of liquid metal temperature.

Platinum rhodium disposable thermocouple is noble metal thermocouple. The thermocouple wire diameter is 0.5mm, and the allowable deviation is -0.015mm. The cathode (BP) on behalf of the chemical composition of platinum rhodium alloy, which contains 30% rhodium, platinum 70%. The anode (BN) for the platinum rhodium alloy, rhodium is 6%. it is commonly known as the double platinum rhodium thermocouple. The maximum temperature of the thermocouple is 1600 DEG C, and the maximum temperature is about 1800 DEG C. Advantages: the double platinum rhodium disposable thermocouple in the thermocouple series has the advantages of highest accuracy, good stability, wide temperature zone, long service life and high temperature limit. Suitable for not only oxidizing and inert atmospheres, but also for short-term use in vacuum, but not for reductive atmospheres or in metallic or nonmetallic vapor atmospheres. An obvious advantage of the B type thermocouple is the need not to compensate the compensation wire, because the thermoelectromotive force in the 0~50 DEG C range is less than 3 μV. Disadvantages: the double platinum rhodium disposable thermocouple deficiency is the thermoelectromotive force. The thermoelectric power is small, sensitive reading low, the decrease of mechanical strength under high temperature, very sensitive to pollution. Precious metal materials are expensive, so it is a larger one-time investment. The working principle of disposable thermocouple is thermocouple is composed of two different components of the grounding conductor ends of synthetic circuit. When the two junction temperature at the same time, it will produce thermal current in the loop. If there is a temperature difference between the working end of the thermocouple and the reference terminal, the display instrument will indicate the temperature corresponding to the thermoelectric potential generated by the thermocouple. Thermocouple choices: measurement of the normal temperature at 1000~1300 DEG C to recommend the use of industrial single use thermocouplesingle thermocouple (RH 10- platinum); measuring the normal temperature at 1200~1600 DEG C to recommend the use of thermocouple (30- RH Pt Rh 6), so in the temperature range used to ensure the service life of thermocouple.
