Description

Technical Field

[0002] The molten steel continuous temperature measurement system is used in the continuous casting machine in the continuous casting workshop of the steelmaking plant. At present, temperature monitoring in the steel production process is crucial to production efficiency and product quality. Usually, a temperature sensor is set in the tube to sense the temperature of the molten steel in the temperature measuring tube.

[0003] However, the position of the temperature sensor in the existing upper exhaust structure of the molten steel continuous temperature measuring tube is fixed and cannot be adjusted, resulting in that it can only sense the temperature of the molten steel at a certain position in the temperature measuring tube. It cannot ensure that the temperature sensor can capture the temperature changes of the entire molten steel fluid in the tube, and thus cannot detect whether the distribution of the molten steel temperature in the tube is uniform.
