Abstract

The invention relates to the technical field of steel ladle lining temperature monitoring and discloses a device for monitoring real-time state of a steel ladle lining. A plurality of air holes are formed in the steel ladle lining; the air holes are respectively distributed in different positions of the steel ladle lining; a plurality of optical fiber sensors are mounted in each air hole; the plurality of optical fiber sensors in each air hole are respectively positioned at different layer depths of the steel ladle lining; each optical fiber sensor is connected with the signal demodulator through a multimode optical fiber; wherein the signal demodulator is connected with the steel ladle lining and used for obtaining temperature signals of different positions and different layer depths of the steel ladle lining, and an upper computer is connected with the signal demodulator and used for obtaining residual thickness prediction values of different positions of the steel ladle lining according to the temperature signals of different positions and different layer depths of the steel ladle lining. The device has the technical effects of being high in temperature monitoring precision andhigh in residual thickness prediction value precision of the steel ladle lining.

Description

technical field [0001] The invention relates to the technical field of ladle lining temperature monitoring, in particular to a real-time monitoring device for the ladle lining state. Background technique [0002] The ladle is an important container for storing and transferring molten steel in the metallurgical industry. Its structure is composed of a steel shell and an inner lining. The inner lining of the ladle includes a working layer, an insulating layer and a permanent layer. During use, because the refractory material lining the ladle is periodically scoured and eroded by high-temperature molten steel, the cracks inside the refractory material gradually expand, resulting in melting loss of the refractory material lining the ladle. In order to avoid major safety accidents and property losses, it is necessary to strengthen the real-time monitoring of the ladle lining temperature, timely and effectively replace the ladle lining refractory material, and make the ladle run s...
