Abstract

The invention provides an anode guide rod steel claw deformation detection method and device; the method comprises the following steps: gathering anode guide rod steel claw images, segmenting image information of each steel claw head, using the image of each steel claw head as a detection area, and binarizing the image of each detection area; calculating a horizontal span value of each steel clawhead in the steel claw arrangement direction according to the binarization processing result, if the horizontal span value a random steel claw head is greater than a corresponding set value, said steel claw is determined to have deformation. The method can easily and accurately detect whether the steel claw has deformation or not, and determines whether a real steel claw deformation amount satisfies with steel claw normal working demands or not according to the maximum deformation amount of the normally working steel claw. The anode guide rod steel claw deformation detection device is simple in structure, small in computing amount, reliable in performance, and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of anode conductive devices for electrolytic aluminum, and in particular relates to a method and a device for detecting deformation of a steel claw of an anode guide rod. Background technique [0002] The anode for electrolytic aluminum is an important part of the electrolytic aluminum production system. It consists of anode guide rods, steel claws, explosive welding blocks, cast phosphorus iron, and anode carbon blocks. In the production of electrolytic aluminum, the lower part of the anode carbon block needs to be immersed in the high-temperature electrolyte in the molten state in the electrolytic cell. With the continuous consumption of the anode carbon block, the entire anode also needs to move down continuously. The temperature increases accordingly. When the anode carbon block is consumed to the specified remaining thickness, the entire anode needs to be taken out of the electrolytic cell, after cooli...
