DEVICE FOR REMOVING SLAG FROM ELECTRIC ARC FURNACE Russian patent published in 2024 - IPC B22D43/00 F27D3/15 

FIELD: metallurgy.

SUBSTANCE: device for removing slag contains a working element for immersion in the melt, made in the form of a water-cooled scraper (1), placed on a water-cooled rod, and, simultaneously working in tandem with it, a device for downloading slag. The water-cooled rod is made in the form of backlash-free water-cooled pipes (2, 3) welded to each other for lateral supply and drainage of water with inlet (5) and outlet (6) fittings permanently fixed through the corner (4). On one side, the rod contains a handle (7) in the form of a frame, and on the other side, a water-cooled scraper containing two water-cooled screens, walls and a bottom, rigidly connected through a connecting tube. The device for downloading slag consists of a body in the form of a bracket of a curved ring shape, reinforced by welding with a diagonal brace, installed on a support with a hook for fixation in the furnace window, interconnected thrust shields, plates and bars and axially installed cone rollers. The conical rollers of the device are configured to move the said water-cooled rod with emphasis on them.

EFFECT: lighter and simplified design.
