Abstract
The utility model relates to a combined thermocouple. The combined thermocouple contains two electrocouple wires and a refractory fiber cloth, wherein a ceramic insulator is sleeved on each electrocouple wire; one end of one electrocouple wire is connected with one end of the other electrocouple wire to form the hot side of the thermocouple; each ceramic insulator has multiple sections; the sections are sleeved on each electrocouple wire continuously; and the outside of the ceramic insulator is wrapped and bundled with the refractory fiber cloth. The combined thermocouple in the utility model has the following advantage: the two electrocouple wires of the thermocouple are isolated effectively so that even if the furnace temperature is up to 1400 DEG C, the shunting error can not be generated. Each ceramic insulator has multiple sections so that the ceramic insulator can not be broken at a large bending angle; the refractory fiber cloth is used to wrap the ceramic insulators; the electrocouple wires do not contact with the gas phase of the furnace and can not be oxidized; even if the billet surface generates liquid slag, the liquid slag can be prevented from invading the inside of the porcelain knob so as to cause short circuit of the thermocouple; and the combined thermocouple has good reliability.
Description
Technical field
The utility model relates to thermopair, especially for the combined hot galvanic couple of measuring high temperature.
Background technology
In order to study the rational heating process system of heating furnace heating system, temperature schedule, formulation and optimization steel billet, all need surface and the internal temperature of steel billet in heating process in the stove carried out the direct-on-line continuous coverage, be beneficial to heating state in the true understanding steel billet stove, can be used for many-sides such as the examination of heating furnace function, the extraction of mathematical model coefficient and modelling verification, heating problems diagnosis and heating process optimization.
Steel billet temperature generally adopts armoured thermocouple in the on-line measurement stove at present.Armoured thermocouple is that thermocouple wire and ceramic insulating material are pressed on the assembly that forms through drawing in the protection metal pipe together, and when the temperature of thermopair middle part surpassed 600 ℃, the resistance of its insulation course produced streaming error with regard to decline.In the armoured thermocouple field-mounted process since install required, be armoured thermocouple bending when maximum (near 90 °), thermo wires ruptures easily, if do not know that from the outside thermo wires fracture also continues to use, temperature test just can not get correct result, wastes time and energy.Simultaneously, general armoured thermocouple serviceability temperature scope is many in 1100 ℃, and the measuring accuracy more than 1100 ℃ just can not guarantee.
The utility model content
Technical problem to be solved in the utility model is: the defective at prior art exists, a kind of combined hot galvanic couple is provided, and its thermo wires is easy fracture not, good reliability.
The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: a kind of combined hot galvanic couple, and it comprises two thermo wires and refractory fiber cloth; Be respectively installed with porcelain tube on two thermo wires, an end of two thermo wires is connected to form the hot junction of thermopair; Described porcelain tube is a multistage, and porcelain tube a section be enclosed within on the thermo wires continuously; The porcelain tube outside is wrapped up and is tied up with refractory fiber cloth.
In the such scheme, described refractory fiber cloth adopts high temperature resistant steel wire to tie up.
Compared with prior art, the utility model advantage is: take effective isolation between two thermo wires of the thermopair of employing, even furnace temperature up to 1400 ℃, can not produce streaming error yet.Porcelain tube is a multistage, and angle of bend can be very big and can not fractures, and is wrapped up by refractory fiber cloth between the porcelain tube, thermo wires does not contact with furnace gas, can be not oxidized, even billet surface produces liquid slag, can prevent that also it from invading porcelain knob inside and causing galvanic couple short circuit, good reliability.

Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
Fig. 3 is that the temp measuring system with the utility model embodiment is formed synoptic diagram.
Embodiment
As shown in Figure 1, 2, the utility model embodiment comprises two thermo wires 2 and refractory fiber cloth 4; An end that is respectively installed with porcelain tube 3, two thermo wires on two thermo wires is connected to form the hot junction of thermopair; Described porcelain tube is a multistage, and porcelain tube a section be enclosed within on the thermo wires continuously; Tie up firmly with the refractory fiber cloth parcel and with high temperature resistant steel wire 5 porcelain tube 3 outsides outside the portion of hot junction.The length of every section porcelain tube 3 can intercept arbitrarily according to bending radius is installed.
As shown in Figure 3, during work, the hot junction of present embodiment thermopair 6 is embedded in the steel billet 1, and measuring junction is connected with moisture recorder 7, and moisture recorder 7 enters in the stove with steel billet 1, carries out the step of tracking and testing in the stove.
Test steel billet 1 in the operational process, passes to temperature signal moisture recorder 7 recording storage always in stove.After coming out of the stove, from registering instrument, takes out on steel billet temperature-measuring results.
