Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical continuous casting equipment, specifically to a fixing device for a temperature sensor used for continuous temperature measurement of molten steel in continuous casting. Background Technology

[0002] The temperature of molten steel in the tundish of a continuous casting machine is a crucial thermal parameter in the continuous casting process. The temperature and its stability directly affect the quality of the cast billet and the production sequence. Too low a pouring temperature can easily cause blockage of the tundish nozzle, accompanied by fluctuations in the liquid level in the crystallizer, resulting in inclusions, cracks, and even production interruptions. Too high a pouring temperature results in a thin billet shell exiting the crystallizer, and dynamic bulging causes fluctuations in the liquid level, also leading to inclusions and cracks, and in severe cases, production accidents. Therefore, it is necessary to control a reasonable and stable superheat. Continuous and accurate measurement of the molten steel temperature in the tundish is a prerequisite for ensuring reasonable superheat control. This system effectively achieves continuous detection of the molten steel temperature in the tundish. However, because the equipment is in a continuous high-temperature environment for a long time, the temperature sensor mounting base is prone to high-temperature oxidation and burn-off, resulting in substandard accuracy. This causes the temperature sensor mounting base to be directly exposed to the high-temperature environment, leading to rapid oxidation and burn-off, and a short service life. After the base burns out, the temperature sensor is not securely installed, easily leading to breakage, severe corrosion, reduced lifespan, and increased costs. Furthermore, the probe, after being exposed to high-temperature radiation, results in inaccurate temperature measurements, misleading the control of molten steel temperature and hindering billet quality control.
