working principle

*Provide multiple fast thermocouplesUsed to measure the temperature of molten steel and high-temperature molten metal, it is a disposable consumable thermocouple. Its working principle is based on the thermoelectric effect of metals, using the temperature difference generated at both ends of the thermocouple to measure the temperature of molten steel and high melting metal. The structure of a speed thermocouple mainly consists of a temperature measuring thermocouple head and a largepaper tubeComposition. My head is mainly welded with positive and negative wirescompensating lead wireAbove, the compensating wire is embedded in the bracket, which is covered with a small paper tube and supported and protected by quartz. Externally equipped with anti slag caps, all components are concentrated in the mud head and bonded together with refractory filler to form a whole, which cannot be disassembled, so it is disposable

structure

*Provide multiple fast thermocouplesThe structure is mainly composed of a temperature measuring thermocouple and a large paper tube. The main components of the thermocouple head are positive and negative thermocouple wires welded onto the compensating wire, which is embedded in the bracket. The bracket is covered with a small paper tube, and the thermocouple wires are welded onto the compensating wirequartzSupport and protection. It is equipped with an anti slag cap, and all components are concentrated in the mud head and bonded together with refractory filler to form a whole, which cannot be disassembled, so it is disposable.

Instructions for use

1Select the appropriate length of protective paper tube and suitable temperature gun based on the measured object and range.

2Quicklythermocoupleloaded inInfrared thermometerGo up and reset the secondary instrument pointer (or digital display) to zero. This indicates good contact and can be used for measurement.

3Quick thermocouple insertion depth into molten steel300－400mmIt is advisable not to measure on the furnace wall or slag during measurement. It should be done quickly, steadily, and accurately. When the secondary instrument obtains the result, the gun should be immediately lifted and the fast thermocouple should be usedmolten steelIntermediate immersiontimemust not exceed5Seconds, otherwise it is easy to burn the thermometer gun.

4After removing the thermometer from the furnace, remove the used thermocouple and install a new one. Pause for a few minutes to prepare for the next measurement. It is not allowed to measure or disassemble continuously, otherwise it may cause temperature fluctuations.

Thermocouple Process Description

1Consumable typeFast thermocouple(Temperature probe) is used for steelmaking and ironmaking processes, including electric furnaces, converters, and refining furnacesLFA temperature sensor designed to measure the temperature of liquid metal in furnaces, oxygen blowing stations, ladles, ladles, intermediate ladles, etc.
2、Fast thermocoupleIt is achieved by measuring thermoelectric potential to measure temperature, and its main part is the thermocouple, which is composed of two different metal materials, compensating wiresUThe quartz tube, plastic bracket, high-temperature mud head, protective cap, and paper tube are integrated into one. Although it is a consumable product, its performance will directly affect the quality of the tested product. Therefore, for the production process of fast thermocouples, the quality, installation, welding, technical testing, inventory management, and other requirements for various components are very strict.
3When in use, simply connect the temperature gun and insert it manually or mechanically into a certain depth of high-temperature melt. The obtained thermoelectric potential is transmitted to an intelligent display device to obtain the temperature value of the melt.
