In the metal smelting process of the vacuum induction continuous casting furnace, the actual heating temperature is detected by a thermocouple or an infrared detector and then fed back to a control system, so that the smelting heating power is controlled. The main temperature measuring device of the vacuum induction continuous casting furnace at present comprises an infrared radiation temperature measuring device and a thermocouple temperature measuring device, although the infrared radiation temperature measuring device has high measuring speed and can measure the temperature of an object which is difficult to approach, the same detecting result is easy to be influenced by the environment, the measuring range is not wide by the thermocouple, the measuring precision is not as high as that of the thermocouple, and the vacuum induction smelting process has higher requirements on the temperature measuring precision, so the thermocouple is more suitable for the temperature measuring device of the vacuum induction continuous casting furnace.
The thermocouple temperature measuring device often comprises a compensation lead wire for extending the cold end of the thermocouple and connecting with a thermometer to form a temperature measuring system, and the working environment is higher in temperature. At present, the common thermocouple compensation wire has the following conditions: the insulating and sheathing materials are made of polyvinyl chloride or polytetrafluoroethylene, the highest use temperature can only reach about 200 ℃, and the heat resistance is poor. However, in the process of ingot casting by the vacuum induction continuous casting furnace, the surface temperature of the spindle is higher, the compensating wire inside the vacuum induction continuous casting furnace is often damaged easily at high temperature because the surface insulator is not high temperature resistant, once the surface insulator is damaged, thermocouple short circuit is very easy to cause so that the detection is inaccurate, a temperature control system sends out an error signal, the whole ingot casting smelting process is further influenced, the ingot casting process is unstable, and ingot casting failure is very easy to cause.

The insulating layer material of the compensating lead for the thermocouple is formed by combining a single-sided calcined mica tape and a polytetrafluoroethylene film, and the sheath material of the compensating lead is quartz fiber yarns, so that the insulating wire core of the compensating lead can normally and stably work in a high-temperature environment at the temperature of 450 ℃ and has good high-temperature resistance. CN211208061U discloses a compensation cable for high temperature resistant thermocouple, comprising a compensation cable core, a round corner quadrilateral shielding net frame, an electric cable core, a signal transmission cable core, an aerogel felt belt, a polyimide composite insulating layer, a round shielding net frame and a ceramic silicon rubber layer, wherein a supporting foam cylinder is arranged in the center of the compensation cable core, a compensation wire and a limiting foam cylinder are arranged around the supporting foam cylinder, an inner core of the compensation wire is twisted by an anode wire and a cathode wire, and the outer core of the compensation wire is wound with a composite mica belt and a nickel-plated copper wire braided shielding net; the round corner quadrilateral shielding net frame and the round shielding net frame are both provided with single-core copper grounding wires, and the aerogel felt belt is internally filled with a thermoplastic polyethylene rubber layer. The utility model integrates the compensation lead and other cable cores into one cable by adopting a multilayer shielding and multilayer heat insulation mode, so as to form the comprehensive cable which is suitable for the thermocouple measurement field, has good high temperature resistance and flexibility, and has the potential of improving the thermocouple measurement length and accuracy.
However, the current improvement of the thermocouple compensation wire often adopts a form of winding insulating materials in multiple layers, so that the operation is complicated, the material cost is increased, and the bending flexibility of the thermocouple compensation wire is reduced.
