Problems solved by technology
[0002] During the use of the desulfurization mixing head, hot slag accumulates seriously, and at the same time, the high temperature condition will seriously increase the work difficulty of maintenance personnel, so the stirring head is continuously corroded, resulting in uneven stirring in molten iron, weakened desulfurization effect, and the concentricity of the stirring device shifts and vibrates Increased, thereby shortening the life cycle of the stirring head
[0003] In the prior art, the sticky slag on the surface of the stirring head is usually cleaned by steel brazing, but due to the hard sticky slag and the difficulty of cleaning, as well as the mechanical damage caused to the stirring head during the cleaning process, especially the cleaning of the stirring blades, the stirring head The service life of the desulfurization stirring head is continuously reduced, so there is a need for a device and method that can effectively prolong the service life of the desulfurization mixing head

Embodiment 1
[0027] Such as figure 1 As shown, a device for prolonging the service life of a desulfurization mixing head includes a lifter and a slag scraper. The lifter is a cylinder or an electric cylinder including a cylindrical fixing part 1 and a rod-shaped piston 2. The piston 2 can be placed on the fixing part 1 reciprocating movement in the axial cavity; the slag scraper includes a slag scraper 3 and a triangular prism-shaped scraper head 4, the middle part of the slag scraper 3 and the end of the piston 2 are locked by bolts, and the slag scraper 4 is set on the slag scraper 3 ends, the base of which is a right triangle.
[0028] Use this device to clean the desulfurization stirring head, the steps are as follows:
[0029] (1) After the molten iron is stirred, lift the stirring head to the slag scraping position, and use the lifter to lower the slag scraper to the first slag scraping position, such as figure 2 shown;
[0030] (2) The stirring head turns on and rotates, and the...

A device and method for prolonging the service life of a desulfurization stirring head belong to the technical field of converter metallurgy machinery. The device includes a lifter and a slag scraper. The lifter includes a cylindrical fixing member and a rod-shaped piston. The rod-shaped piston is arranged in the axial cavity of the cylindrical fixing member and can reciprocate axially along the cylindrical fixing member. The slag device includes a slag scraper and a slag scraper head, the middle part of the slag scraper is fixedly connected with the end of the piston, and the slag scraper is triangular prism-shaped and is arranged at the end of the slag scraper. Utilizing the present invention to scrape slag on the desulfurization stirring head can reduce mechanical wear in the cleaning process, prolong the service life of the stirring head by about 1 / 10, stir molten iron more evenly and stably, and greatly reduce the high-temperature workload of maintenance personnel.
Description
technical field [0001] The invention belongs to the technical field of converter metallurgical machinery, and in particular relates to a device and a method for prolonging the service life of a desulfurization stirring head. Background technique [0002] During the use of the desulfurization mixing head, hot slag accumulates seriously, and at the same time, the high temperature condition will seriously increase the work difficulty of maintenance personnel, so the stirring head is continuously corroded, resulting in uneven stirring in molten iron, weakened desulfurization effect, and the concentricity of the stirring device shifts and vibrates Increased, thereby shortening the life cycle of the stirring head. [0003] In the prior art, the sticky slag on the surface of the stirring head is usually cleaned by steel brazing, but due to the hard sticky slag and the difficulty of cleaning, as well as the mechanical damage caused to the stirring head during the cleaning process, e...
