Description

Technical Field

[0001] The utility model relates to a scraping device, in particular to a device capable of scraping and cleaning the iron slag adhered to the beam of a blast furnace taphole machine, belonging to the technical field of iron slag cleaning equipment for the beam of a taphole machine. Background Art

[0002] The blast furnace taphole machine in ironmaking is one of the most important production equipment in the blast furnace. It operates frequently in a high-temperature slag and iron environment and inevitably comes into direct contact with high-temperature slag and iron during operation. Therefore, the consumption of this equipment is relatively large. The beam of the taphole machine is often wrapped by the splashed slag and iron, which affects the driving of the trolley that moves back and forth on the beam. The trolley cannot move forward and backward flexibly, which affects the taphole time during the tapping process. Even the unsmooth driving of the trolley causes fluctuations in the size and angle of the taphole channel of the blast furnace, posing a great hidden danger to safety production. Therefore, it is necessary to clean the slag and iron on the beam of the taphole machine. Currently, the slag and iron adhered to the beam are cleaned manually. The staff holds a long shovel to scrape the slag and iron on the beam. This process is time-consuming and laborious, and the cleaning is not thorough. Therefore, an iron slag scraping device is needed, which is required to efficiently assist the staff in cleaning the slag and iron on the beam, thereby reducing the labor intensity of the staff and improving the cleaning efficiency of the slag and iron on the beam.
