Abstract

The invention provides a system for detecting the bending degree of a sublance of a steelmaking converter, which comprises a sublance probe, a measuring position limiter and a signal acquisition device, and is characterized in that the signal acquisition device is used for acquiring image information of the sublance probe; the signal processing device is used for receiving the image information, analyzing the image information to obtain an image display interface and then outputting an analysis result; and the signal control device is used for automatically controlling whether the sublance at the measuring position continues to descend or not according to the analysis result. On the other hand, the invention further provides a method for detecting the bending degree of the sublance of the steelmaking converter. According to the system and method for detecting the bending degree of the sublance of the steelmaking converter, the technical problems that in the prior art, bending of the sublance cannot be found in time, the sublance is prone to being damaged, and production is affected are solved, the equipment failure rate is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a detection system and method for the bending degree of a sub-lance of a steelmaking converter. Background technique [0002] Steelmaking converter sub-lance is the main method used in converter smelting, mainly to measure the oxygen content and carbon content of molten steel. The sub-gun operation is to connect the probe at the connection position, then rotate to the measurement position, then lower the gun, and enter the converter through the sub-gun port for detection. Because the temperature of the molten steel in the converter is too high, the lower end of the gun body will be damaged during the long-term use of the sub-gun. Bending to one side, and the sub-gun muzzle is relatively small. If the sub-gun is not bent in time, the bending degree will cause the sub-gun to be inserted outside the sub-gun muzzle, resulting in measurement failure and damage to the sub-gun. It is...
