Problems solved by technology

And the two methods are to immerse the thermocouple protection tube or the temperature-sensing spy tube for radiation temperature measurement in the molten steel in the tundish. Long-term immersion will have more or less influence on the temperature field and chemical composition of the molten steel in the tundish, and Increased temperature measurement cost

Embodiment 1

[0027] Embodiment 1: as shown in Figure 2 and Figure 3, the structure of the present invention: a temperature measuring device is installed on the tundish plug rod 5, and the temperature measuring device is a thermocouple temperature measuring device in this example, as shown in Figure 3, It includes a thermocouple 13, a compensation wire 9 and a temperature measuring instrument 10. The thermocouple 13 is connected to the temperature measuring instrument 10 through the compensation wire 9. The thermocouple 13 is equipped with a protection tube 12, which is placed in the stopper rod 5. The protection tube 12 passes through the clamp The holding pipe 11 is connected with the junction box 8 . Its thermocouple 13 is S type, or B type, or W3 type, or W5 type thermocouple, adopts S type in this example.

[0028] When in use, just move the installation bracket of the thermocouple temperature measuring device above the stopper rod 5 and get final product. The present invention can be...

Embodiment 2

[0029] Embodiment 2: as shown in Figure 2 and Figure 4, the structure of the present invention: a temperature measuring device is installed on the continuous casting tundish plug rod 5, and the temperature measuring device is a radiation temperature measuring device in this example, as shown in Figure 4 shown, including a lens 16, an adjustable light bar 17, a detector 18, an optical fiber 14, and a temperature measuring instrument 10. The detector 18 is connected to the temperature measuring instrument 10 through an optical fiber 14, and the adjustable light bar 17, The lens 16 and the protective glass 15 are placed above the stopper rod 5 . In this example, the stopper rod is a stopper rod with a small hole at the top, as shown in Figure 6.

[0030] During use, as long as the radiation temperature measuring device is aimed at the upper opening of the stopper rod 5 . The light barrier 17 is adjusted so that the infrared light beam inside the stopper rod 5 is focused on the d...

Abstract

This invention relates to a trough stopper with a continuous temperature-test function, which utilizes the present stopper to replace the outer protection tube of a temperature sensor in a thermocouple temperature-test device and a temperature-sensitive peering tube to form a new type of stopper with temperature-test function including installing a temperature-test device on a stopper of a conticast trough, a thermocouple or a radiation temperature-test device, which is advantaged that the tested temperature is the actual one when molten steel is poured into a trough and crystallized, so the temperature is accurate.

Description

technical field [0001] The invention belongs to the technical field of measurement and detection and the field of metallurgical equipment accessories, in particular to a tundish stopper rod with continuous temperature measurement function. Background technique [0002] Consumable thermocouples are usually used in international metallurgical production to measure the temperature of molten steel. This method can only measure intermittently and cannot measure the process temperature. Since the tundish with plasma heating equipment has very strict requirements on the stability of molten steel temperature, continuous temperature measurement is urgently required. When smelting or casting new steel types or special steels, it is often necessary to measure the temperature of molten steel frequently, which makes temperature measurement Increased costs, high labor intensity, and poor operating environment hinder the improvement of automation level. In particular, the improvement of t...
