Description

TECHNICAL FIELD

[0002] The graphitization furnace is important equipment for making carbonaceous raw materials into graphite products. Its structure includes a furnace body, a heating system (such as resistance or induction heating, which can be heated to several thousand degrees Celsius), a heat preservation layer, and a feeding and discharging device. It is widely used in the steel, metallurgy, and battery manufacturing industries, and can produce graphite electrodes, negative materials, and other high-temperature and conductive products. The working principle is that carbon atoms rearrange at high temperatures after the carbonaceous raw materials are put into the furnace, and are converted into graphite crystal structure. Since accurate temperature control is required during this process, the temperature measuring structure is crucial to the graphitization furnace.

[0003] The existing graphitization furnace temperature measurement is usually by inserting a graphite temperature probe directly into the furnace, and then measuring the temperature on the surface of the graphite temperature probe with an infrared temperature detector to determine the temperature inside the furnace. Although this method can measure the temperature inside the furnace, it still has some problems. After the graphite temperature probe is inserted into the furnace, it needs to be fixed to prevent the graphite temperature probe from moving inside the furnace. At the same time, the infrared tester is easily disturbed by the external environment when detecting the temperature of the graphite temperature probe, thereby reducing the accuracy of temperature measurement.
