is used for scraping off and cleaning of ceramic crucibles in aluminium crucible\nmelting furnaces. This consists of a device with 3 or 4 shovels, which if necessary\ncan be operated individually under pneumatic power like a compressed air\nhammer. After the 1st downward stroke, the shovels are moved upward, rotated\nthrough the specified angle and then lowered 2 \u2013 5 times to clean the crucible.\nAbout 300 mm of aluminium are left in the crucible, so that the residue can then\nbe removed from the furnace with the aid of a modified \u201cslag excavator\u201d. This\nwork must be carried out with the crucible still in the warm, operating condition,\nsince if the crucible is too cold, not only will the dross be removed, but the cru-\ncible wall can also be severely damaged. Mechanical milling devices have not\nproven effective in this application.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
