The general treatment mode of the oxygen lance slag sticking comprises the following steps: a slag removing device is arranged at the mouth of the oxygen lance, and the oxygen lance is matched with manual cleaning after the oxygen lance goes off the line. The slag removing mode is restricted by the service life of the slag scraping device, and the normal production rhythm is seriously influenced because the service life of the equipment is short due to the structure, the material and the like of the equipment; the slag removing effect of the slag scraping device is poor, and the burden of manual slag removal under the line can be increased. Therefore, it is necessary to design and manufacture a novel steel slag scraper and scraper device, so as to prolong the normal service life of equipment, improve the online rate of the equipment, improve the slag removal effect and reduce the labor hour consumption.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a slag scraping device for a converter oxygen lance, which can be used for removing sticky slag attached to the outer surface of the oxygen lance, has a good slag scraping effect and a long service life, and solves the problems in the background technology.
The technical scheme of the utility model is as follows:
a slag scraping device for a converter oxygen lance comprises a scraper, scraper pin holes, scrapers, scraper grooves, scraper adjusting jackscrews and scraper fixing jackscrews, wherein the scraper is provided with the scraper pin holes and two scraper grooves matched with the scrapers; the scraper adjustment jackscrew sets up along scraper central line direction, and the perpendicular scraper central line direction of the fixed jackscrew of scraper sets up, and threaded connection is on the scraper blade respectively to scraper adjustment jackscrew and the fixed jackscrew of scraper, and scraper adjustment jackscrew top is at the rear end of cuboid scraper, and the fixed jackscrew top of scraper is at the side of cuboid scraper, and whole is symmetrical structure.
Two scraper grooves matched with the scrapers on the scraper are rectangular.
The included angle of the extension lines of the center lines of the two scraper grooves matched with the scrapers on the scraper is 90 degrees.
And threaded holes matched with the scraper adjusting jackscrew and the scraper fixing jackscrew are respectively formed in the scraper.
When the slag removing device is used, the two converter oxygen lance slag removing devices with the same structure are symmetrically arranged at two sides of the oxygen lance opening, so that the four scrapers are uniformly arranged along the periphery of the oxygen lance, the oxygen lance is lifted from the middle of the two converter oxygen lance slag removing devices, steel slag adhered on the oxygen lance can be removed through the four scrapers, and the slag removing operation strength of the surface of the oxygen lance after the oxygen lance is taken off the production line is reduced.
The utility model has the beneficial effects that: can clear away the slag that glues that the surface of adhering to the oxygen rifle takes place, scrape sediment effectual, long service life has reduced the clear sediment operation intensity on oxygen rifle surface after inserting the production line, has improved continuous operation's efficiency.
