The tundish current stabilizer is a functional refractory material which is arranged at the bottom of the tundish impact area and used for stabilizing the flow of molten steel in the tundish nozzle area, preventing steel slag from being involved in the molten steel to cause the internal quality defect of steel billets, promoting the floating of inclusions and reducing the splashing of the molten steel. This area is the area where the tundish is most impacted by the molten steel and most eroded, and is therefore also the main part affecting the ladle age. However, the part is just positioned at the bottom of the middle ladle, is not easy to observe during production, and can lead to the middle ladle to penetrate the middle ladle if not found in time, thereby causing great potential safety hazard and equipment damage. Therefore, a temperature measuring mechanism is added in the area, and the ladle temperature of molten steel casting and the arrival temperature of molten steel are monitored. The accident that the temperature of the middle ladle shell rises and the steel leakage is caused by corrosion of the refractory material is avoided.
Because of the factors of the installation position and the installation environment, the existing temperature measuring mechanism cannot meet the severe temperature environment, and the installation position is positioned at the bottom of the tundish car and is inconvenient to install. The temperature cannot be displayed at any time and monitored at any time.
