The accuracy of temperature measurement and the length of equipment life play an important role in the stable and long-term operation of large-scale closed titanium slag electric furnaces. If the temperature is inaccurate and the failure rate is high, it will cause serious difficulties in slag and iron discharge, thereby affecting the operation and life of related equipment, increasing maintenance costs, and posing certain safety hazards.
[0003] Most of the existing titanium slag electric furnace shell temperature measurement equipment uses ordinary power cords and thermocouples with integrated plastic material transmitters with stainless steel sheaths. The furnace body thermocouple uses an integrated transmitter, which is close to the outer wall of the furnace shell and operates in a high temperature environment for a long time. The integrated transmitter has a high failure rate, and unstable operation misleads the production process and affects product quality. The original thermocouple sheath material is prone to high-temperature oxidation and severe sheath breakage. Therefore, it is urgent to design a titanium slag electric furnace body temperature measurement equipment to solve the above problems. Summary of the invention

The furnace body thermocouple uses an integrated transmitter, which is close to the outer wall of the furnace shell and runs in a high temperature environment for a long time. The integrated transmitter has a high failure rate, and the unstable operation misleads the production process and affects the product quality. The original thermocouple sheath material is easy to oxidize at high temperature and the sheath breaks seriously.

[0006] Preferably, the high temperature resistant ceramic terminal blocks are connected to the high temperature resistant shielded compensation control lines which are centrally laid on a fire retardant cable tray.
[0007] Preferably, the high temperature resistant shielded compensating control lines are connected to high temperature resistant ceramic terminals which are centrally laid on a fire-resistant and flame-retardant cable tray, and each high temperature resistant shielded compensating control line is connected to an isolation fence.

First, the high-temperature resistant ceramic sleeve is inserted into the corresponding position according to the different wall thickness of the electric furnace body shell, and the K-type thermocouple is inserted into the high-temperature resistant ceramic sleeve. The high-temperature resistant ceramic terminal is installed in the K-type thermocouple terminal box. The K-type thermocouple is divided into five layers, and each layer has K-type thermocouples evenly distributed. The high-temperature resistant shielded compensation control line is centrally laid on the fire-retardant cable tray by connecting the high-temperature resistant ceramic terminal. Each line is connected to the isolation fence and is generally concentrated in the transmitter cabinet to prevent external interference. The high-temperature resistant shielded compensation control line converts the temperature signal into an analog quantity -mA through the isolation fence.
