Abstract

The invention discloses a continuous temperature measuring device for a tundish molten steel. The device comprises a tundish, a long nozzle connected to the top of the tundish, a submersed nozzle connected to the bottom of the middle of the tundish and a temperature measuring weir plate arranged in the tundish, the tundish is divided into a mixing area and a casting area by the temperature measuring weir plate, the long nozzle is arranged in the mixing area, and the submersed nozzle is arranged in the casting area; the temperature measurement weir plate comprises a weir plate refractory material body, a temperature measurement hole is formed in the weir plate refractory material body, a temperature measurement refractory material protection sleeve is arranged in the temperature measurementhole, a temperature measurement thermocouple is arranged in the temperature measurement refractory material protection sleeve, and the temperature measurement thermocouple is connected with a temperature signal acquisition device through a temperature signal line. According to the continuous temperature measuring device, the problem that a temperature measuring probe cannot continuously detect the temperature of molten steel is solved, and meanwhile the problems that the temperature measuring probe is short in service life and high in temperature measuring cost are solved.

Description

technical field [0001] The invention relates to the technical field of tundish metallurgy, in particular to a continuous temperature measuring device for molten steel in a tundish. Background technique [0002] The tundish is one of the important intermediate links in the steelmaking production process. The molten steel in the ladle is injected into the tundish through the long nozzle set on the upper part of the tundish. injected into the crystallizer. The stability of the temperature field, flow field, and liquid level of molten steel in the tundish is crucial to the final quality. The temperature of molten steel in the tundish is measured by a temperature measuring device. [0003] At present, there are two main methods for measuring the temperature of molten steel in the tundish: one is to use a temperature measuring probe and a one-time consumption thermocouple. Measure the temperature of molten steel. Its structure is composed of a temperature measuring thermocouple...
