Problems solved by technology

Since there is only one layer of outer metal casing, in some harsh environments with high temperature corrosion, the service life of traditional single-layer armored thermocouples is short, which is not conducive to cost control and efficiency improvement
[0003] In the prior art, after heating the outer metal casing to the specified temperature, the staff needs to move the outer metal casing to the position of the hot rolling mill. The moving process is laborious and laborious, which slows down the armored thermocouple and The processing of the outer metal casing is easy to drop during the movement

Abstract

The invention discloses a processing technology of a temperature-measuring armored thermocouple, which comprises the following steps: heating an outer metal casing to 700-1200°C; transporting the heated metal casing to a hot rolling mill through transportation equipment; Install the single-layer armored thermocouple into the outer metal sleeve, and use a hot rolling mill to roll the thermocouple and the metal sleeve. The invention changes the material of the outer metal casing and hot-rolls the armored thermocouple, thereby significantly improving the service life of the armored thermocouple and increasing the temperature measurement effect of the armored thermocouple.

Description

technical field [0001] The invention belongs to the technical field of thermocouple processing, and in particular relates to a processing technology of a temperature-measuring armored thermocouple. Background technique [0002] At present, the traditional armored thermocouple is made by cold drawing of the outer metal casing, insulating material and dual wire. Among them, the outer metal casing is generally made of stainless steel or nickel-based superalloy, which has good oxidation resistance and corrosion resistance below 1100 °C. Since there is only one layer of outer metal casing, the service life of traditional single-layer armored thermocouples is short in some harsh environments with high temperature corrosion, which is not conducive to cost control and efficiency improvement. [0003] In the prior art, after heating the outer metal casing to the specified temperature, the staff needs to move the outer metal casing to the position of the hot rolling mill. The moving ...
