FACILITY FOR FILTRATION OF MELTED METALS AND ALLOYS Russian patent published in 2010 - IPC C22B9/02 C22B21/06 

FIELD: metallurgy.

SUBSTANCE: facility consists of working chamber installed in case; also working chamber is formed with walls and bottom made out of refractory material and has inlet and outlet openings. The bottom of the working chamber is made step-like in the direction of the outlet opening. A vertical partition not reaching the bottom and a filter element are installed inside the working chamber; also the filter element is secured inside the working chamber between its walls and the vertical partition. A flap cover with heating elements and electro-mechanical drive is arranged in an upper part of the working chamber. The filter element is made as successively arranged porous filter partitions with dimension of pores at the first partition relative to the second one equal to 2/1-2/1.5. The filter partition installed at the inlet opening is arranged with a rise of 3-5 degrees in the direction of metal flow to the side of the outlet opening, while the filtering partition at the outlet opening is installed horizontally.
