Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tundish auxiliary assembly, concretely relates to a tundish temperature measuring device. BACKGROUND

[0002] Tundish is a refractory container used in short process steelmaking, which first receives molten steel poured from a ladle, and then distributes to each crystallizer through tundish nozzle. In actual use, the temperature of molten steel in the tundish needs to be measured to understand the temperature change of molten steel in real time.

In actual operation, the operator usually inserts the temperature measuring probe into the molten steel in the tundish. Although the temperature measuring probe has a long axial dimension, there is still a risk of skin burns due to high temperature, resulting in a high risk of tundish molten steel temperature measurement operation.
