メタル分離装置に関する。Detailed Description of the Invention The present invention relates to an apparatus for separating and removing slag (slag) from molten metal melted in a melting furnace such as an electric furnace or a cupola. A slag/molten metal that uses the difference in specific gravity of the molten metal to continuously or intermittently separate the two.

ができないという問題があつた。 For example, when iron raw materials are melted, refined, and refined, acidic oxides such as SiO 2 and Al 2 O 3 , CaO,
Basic oxides such as MgO, sulfur, or trace amounts of heavy metal oxides are dissolved in the molten metal as slag, so it is necessary to remove the slag after oxidation scouring and before moving to the reduction stage. Conventional slag removal work involves: (a) A molten metal pool is provided at the bottom of the melting furnace, a slag discharge port and an iron bath discharge port are provided separately in this pool, and the slag is separated and discharged using the difference in specific gravity. (b) In an induction electric furnace, slag floats to the top of the molten metal due to the difference in specific gravity, so the furnace body is tilted and the slag floating on the molten metal surface is manually scraped out using iron rods, flat iron plates, etc., and the slag that does not melt is removed. When the slag comes out, it is removed by grabbing it from the top of the furnace body with a grab basket-type slag machine, or (c) tapping the molten metal into a ladle, tilting the ladle, and scraping out the slag manually.
However, both methods require a lot of effort, take a long time to remove the sludge, and have problems in that complete separation and removal of the sludge cannot be achieved.

The object of the present invention is to provide a small and efficient slag/metal separation device that can automate slag separation, discharge, and complete separation by providing members.

The separation gutter is pivotally supported in a tiltable manner by a column 8 at approximately the central side in the longitudinal direction, and has a molten metal discharge port 5 at one end and a slag discharge port 6 at the other end. It is formed. A weir member 4 is installed in the separation gutter 3 at a position close to the molten metal outlet 5 and slightly apart from the bottom of the separation gutter 3. The tilting device for the separating gutter 3 is constituted in this embodiment by a tilting cylinder device 7 connected between the support column 8 or the support floor 12 and the separating gutter 3, but it goes without saying that the device for tilting the separating gutter 3 at its supporting point is Any other drive device may be used as long as it rotates the device. For example, tilt center axis 1
1 itself may be rotationally driven via a gear transmission mechanism.

０側へ大きく傾動させてスラグを排出する。 In such an apparatus, the material to be melted is transferred to the melting furnace 1.
After melting, the molten metal 13 is released from the tap 2 of the melting furnace 1.
The hot water is discharged to approximately the center of the separation gutter 3. Separation gutter 3
Inside, the slag 14 in the molten metal floats on the molten metal 15 due to the difference in specific gravity, and the molten metal 15 passes under the weir member 4 and flows out from the metal outlet 5 to the metal ladle 9. The floating slag 14 is blocked by the weir member 4 and does not flow to the metal discharge port side.
The slag is discharged from the opposite slag discharge port 6 to the slag ladle 11. In this case, in order to prevent the molten metal 15 from flowing out from the slag discharge port 6 together with the slag, the height position of both discharge ports 5 and 6, that is, the inclination of the separation gutter 3, is adjusted depending on the amount of molten metal, the state of separation of slag and metal, etc. It is adjusted by a tilting cylinder device 7. As the amount of molten metal in the gutter decreases, the separation gutter 3 becomes a metal ladle 9.
It is tilted slowly to the side, whereby all of the molten metal in the separating gutter 3 is discharged into the metal ladle 9. Finally, since slag remains in the separation gutter 3, the separation gutter 3 is moved to the slag ladle 1 by the tilting cylinder 7.
Discharge the slag by tilting it largely towards the 0 side.

せることができる。 According to the present invention, both ends of the gutter are used as discharge ports, a slag weir member is provided on one side, and the slope of the gutter can be adjusted to maximize separation efficiency according to the amount of molten metal flowing into the gutter. Therefore, it is possible to obtain a small and efficient separation device that can effectively separate and discharge metal and slag. There is less heat dissipation and separation can be completed quickly.
