The invention provides an automatic positioning device and an automatic positioning method for measuring the thickness of a converter lining with laser. The automatic positioning device is fixedly arranged on a converter ring, and comprises three balls distributed triangularly. The automatic positioning method comprises: scanning the automatic positioning device to obtain spatial point cloud coordinate data of the automatic positioning device; recognizing and fitting coordinate values of the centers of the three balls in a laser thickness gauge coordinate system; and solving a conversion relation between two coordinate systems according to the coordinate values of the centers of the three balls in the laser thickness gauge coordinate system and the converter coordinate system, thus positioning a laser thickness gauge. Since the automatic positioning device is fixedly arranged on the converter ring, the coordinate values of the centers of the three balls in the converter coordinate system can be determined; because the balls are in a special shape, automatic recognition and fitting functions of point cloud data during scanning at each position can be accurately realized, the coordinate values of the centers of the balls in the laser thickness gauge coordinate system can be acquired, then the conversion relation between the two coordinate systems can be acquired, and the laser thickness gauge can be positioned.
Description
technical field [0001] The invention relates to the technical field of converter steelmaking, in particular to an automatic positioning device for laser thickness measurement of converter lining; in addition, the invention also relates to an automatic positioning method for laser thickness measurement of converter lining. Background technique [0002] During the oxygen blowing smelting process of the converter, the long-term contact of the furnace lining with high-temperature molten iron, slag and furnace gas will cause local corrosion. As the production progresses, the thickness of the furnace lining will gradually become thinner; when the current thickness is lower than the safe value, major safety accidents such as steel piercing are prone to occur. [0003] At present, with the development of furnace lining repair technology and the wide application of slag splash protection technology, the service life of the converter lining can reach 10,000 to 20,000 furnaces, and the...
