Abstract

The embodiment of the invention provides a crystallizer, a method for measuring the height of the liquid level of molten steel in the crystallizer and a related device. The crystallizer comprises a crystallizer body and a plurality of optical fibers. A plurality of parallel first grooves are formed in at least one side wall of the crystallizer body, and the same ends of the first grooves in the length direction extend to an upper opening of the crystallizer. One end of each optical fiber is independently arranged in the corresponding first groove, and the other ends of the optical fibers extend out of the corresponding first grooves and are used for being connected with a fiber grating demodulator. The accuracy and stability of crystallizer temperature measurement can be effectively improved, and then the accuracy and efficiency of acquiring the molten steel liquid level fluctuation state in the crystallizer through the crystallizer temperature measurement result can be effectively improved.

Description

technical field [0001] The application relates to the field of crystallizer technology, in particular to a crystallizer, a method for measuring the height of molten steel in the crystallizer, and related devices. Background technique [0002] Crystallizer is a kind of equipment for crystallization operation, which is used to cool or evaporate the saturated solution flowing through it to make it reach a certain degree of supersaturation and crystallize. For example, in a continuous casting machine, the crystallizer, as its core component, is a molten steel cooling and forming equipment used to accept molten steel injected from the tundish and make it solidify into a solid billet shell according to the specified cross-sectional shape and enter the continuous casting machine. It is also one of the important means to ensure the normal operation of the continuous casting machine by collecting the temperature of the crystallizer to analyze and determine its internal molten steel f...
