Temperature measuring device and temperature measuring method for measuring temperature of molten metals

#This application is the United States national phase of International Application No. PCT/CN2017/091121 filed Jun. 30, 2017, the disclosure of which is hereby incorporated by reference in its entirety.

#The disclosure relates to the technical field of temperature measurement, in particular to a temperature measuring device and a temperature measuring method for measuring the temperature of molten metals.

#In the metallurgical industry, it is necessary to continuously measure the temperature of molten metals (such as molten steel and molten iron) in real time during production, which is of great significance to improve metal quality and production efficiency and reduce energy consumption.

#The accompanying drawings, which constitute part of this application, are intended to provide a further understanding of the disclosure. The exemplary embodiments of the disclosure and description thereof serve to explain the disclosure, but do not constitute improper restrictions on the disclosure. In the drawings:

#FIG. 1 is a structure diagram of a temperature measuring tube of U.S. Pat. No. 6,846,105B2 in the background art.

#FIG. 2 is a structure diagram of an existing stopper for measuring the temperature of molten steel of Patent CN1936524A in the background art.

#From FIG. 1 to FIG. 10, the marks in the attached drawings represent:

#A1—aluminum carbon material tube, A2—corundum or zirconia material tube, 1—cermet tube, 2—support tube, 3—vent tube, 4—connecting tube, 5—vent hole, 6—infrared temperature measuring probe, 7—signal processor, 8—nut, 9—tundish, 10—molten steel.

#Together with the Figures in the embodiments of the disclosure, the following text will describe clearly and completely the technical solution implemented in the embodiments of the disclosure. Obviously, the embodiments described are merely part of embodiments implemented in the disclosure, not all embodiments. The following description of at least one exemplary embodiment is in fact illustrative only and is in no way intended to limit the disclosure and its application or use. Based on the embodiments of the disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the protection scope of the disclosure.
