SU1217887A1 - Device for feeding aluminium wire to molten metal - Google Patents

Description

The invention relates to metallurgy, specifically to devices for introducing deoxidizing agents into a liquid metal, in particular, for deoxidizing and alloying steel with aluminum.

The aim of the invention is to simplify the design and operation.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. 1 in FIG. 4 - unwinder during transportation of the riot; in fig. 5 - the same, at the moment of capture or release by the frame clamps.

. The proposed device consists of a pull stand 1, a correct stand 2, and an unwinder 3. Unwinder 3 includes a frame 4 for mounting a riot 5 of aluminum wire 6, which is introduced into the molten metal 7 made of parallel arranged upper bottom B and lower bottom 9, having an internal conical surface 10 a clamping clip 1.1, connected by hinges 12 with clamps 13, made in the form of 3 levers. The clamps 13 are provided with grippers 14 and hooks 15 and 16 located on opposite sides of the hinge 12. The grippers 14 are V-shaped, formed by the outer inclined surface 17 and the inner inclined surface 18. A detachable cone 19 is used to center the riot 5 on the frame 4 .

The device works as follows.

At the preparation site, the frame 4 with the cone 19 inserted into it sets riot 5 of the wire 6. After this, the cone 19 is removed. The presser 11 is moored to the lifting device for the hooks 16 and lifted. This leads to a separation of the clamping 13 from the axis of the pressure cover 11. Then the pressure cover 11 with the diluted pressure presses 13 is lowered coaxially with the riot 5 until it lies on the riot. After this, the pins are transferred to the hooks 15 and the rim 11 is raised. In this case, the clamps 13 are reduced to the axis and internal inclined surfaces 18 of the claws 14, are pressed to the outer annular face of the bottom bottom 9 of the frame 4. The grippers 14 of the clamps 13 rise up and same time

The sliding surface 18 extends along the edge of the bottom plate 9, which allows the gripper 14 to enter the space between the bottoms 8 and 9 of the frame 4.

With further lifting of the presser flap 11, the clamps 13 abut against the outer cylindrical surface of the upper bottom 8, and the grips 14 abut against the lower surface of the same bottom and lift the frame 4 with Riot-5. In this position, the decoiler 3 is transported to a device for inserting aluminum wire into the molten metal.

When the unwinder 3 is installed on the workplace after the frame 4 contacts the floor, the pressure cap 11 with the presses 13 continues to fall downwards relative to the fixed rebellion 5 and the frame 4. In this case the presses 13 are pressed against the outer cylindrical surface of the upper bottom 8, which prevents the grippers 14 to exit from the space between

the bottoms 8 and 9. The lid 11 with the clamps 13 is lowered until the outer inclined surfaces 17 of the claws 14 are in contact with the inner conical surface 10 of the lower bottom 9. The clamps 13 are jammed, which ensures the stability of the uncoiler 3 when unwinding the riot 5.

After that, the chuck is removed, the riot 5 is released from the packaging wrapping, the end of the wire 6 is passed through the inner turns of the riot through the opening of the pressure cap 11 and is loaded into the device.

After the unwinding is completed, the decoiler 3 is moored at the hooks 15 and transported to the preparation site.

To separate the presser cover 11, it is moored at the hooks 16 and lifted. The clamps 13 are then diluted, and the outer inclined surfaces 17 of the claws 14 slide along the inner conical surface 10 of the bottom plate 9, which allows the gripper:

there 14 to leave the space between the bottoms 8 and 9. The clips 13 are released from the frame 4, and the uncoiler 3 is prepared to receive a new riot.

The technical and economic advantages of the proposed device as compared with the known one are as follows: due to the exclusion of the Sieka, the design is simplified and the weight of each device is reduced by 11.3 tons; riot charging can be carried out on

transport equipment, which simplifies the operation of the device at the workplace.
