Description

Swapping briquetting device {Apparatus for briquetting swarf}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filtering device used in a steel manufacturing process, and more particularly, to a swab briquetting device for compressing a swab separated and recovered from a filtering device.

In general, if a defect occurs on the surface of the strip due to various factors in the production of stainless hot rolled coil, the grinder facility is used to eliminate the defect.

The grinder facility performs polishing using a polishing belt rotating at a high speed, and the polishing oil is added to reduce the friction generated during the polishing operation.

In addition, the swarf generated as a by-product during the polishing process is mixed with the abrasive oil and introduced into the filtering device.

Subsequently, the swarf and the abrasive oil are separated from the filtering device, and the abrasive oil is recovered and reused. The swarf is fed into a centrifuge, and the remaining abrasive oil is also filtered out and sent to the steelmaking factory for reuse.

At this time, before sending it to the steelmaking factory, the swarf is compressed to make a cake, the squeezed abrasive oil is reused, and the compressed swarf cake is put into an electric furnace.

In FIG. 1, the general filtering apparatus by which a swab is filtered is shown in perspective view.

The strip S to be transported is polished in the polishing cabin 2, where the used waste oil is introduced into the swarf tank 6 through the chute 4.

In the swap tank 6, the swarf included in the waste abrasive oil is transferred to the conveyor 8 and discharged to the outside, and the waste abrasive oil filtered by the swarf from the screen 10 installed at the lower portion is introduced into the connected filter tank 12. Here, the fine swarf is again filtered by the conveyor 14 and transferred to the outside.

Then, the waste abrasive oil is introduced into the clean tank 18 by using the recovery pump 16 to completely remove impurities, and is then resupplied to the polishing cabin 2 using the supply pump 20.

Here, the conveyors (8) and (14) are installed inside the warp duct (22) communicating with the swab tank (6) and the filter tank (12), and a plurality of equally spaced on the outer surface of the conveyor (8) (14). Drag the swarf to the transfer jaw 24 of the and is discharged to the outside.

The swarf discharged to the outside is compressed and then put into the electric furnace.

At this time, the cake put into the electric furnace reduces the temperature in the furnace and at the same time becomes a factor that makes the power consumption extremely.

In particular, the swap cake located at the edge of the electric furnace does not dissolve well in the heat of the molten steel has a problem that takes a long time to dissolve.

If the undissolved swap cake is present, there is a problem in that the slag composition of molten steel dissolved in the electric furnace is poor.

In order to solve these problems, an object of the present invention is to add a carbicide to the swab cake so that the dissolution of the swab cake is triggered by the ignition of the swab cake when the swab cake is put into the electric furnace. It is to provide a swab briquetting device that allows the addition of cigars.

The rod of the cylinder 94 is provided with a gate block 96 serving as a third gate, and a plurality of oil grooves 96a are formed on the right side of the gate block 96.

A slit 96b is formed on one side of the gate block 96, and a gate guide 100 into which the door 98 is fitted is installed on the slit 96b, and a cylinder 102 is provided on one side of the gate guide 100. ) Is installed so that the end of the rod is connected to the door (98).

In addition, a lower portion of the gate block 96 is formed in a triangular shape, and a drain line 104 for draining oil is connected to the lowermost portion of the triangular shape.

The control panel 106 includes all cylinders 88, 94, 102, sensors 60a, 60b, 76a, 76b, 90a, 90b, 94a, 94b, motors 56, 72 And the hydraulic tank 108 can be controlled remotely the swab briquetting device.

The operation of the swab briquetting device according to the present invention configured as described above is as follows.

First, by-products formed by grinding the strips S in the polishing cabin 2, the swarf is contained in the polishing oil or in the form of agglomerates, and thus, the swarf tank 6 along the polishing oil chute 4 as shown in FIG. Abrasive oil, which is introduced into the filter tank, is introduced into the filter tank 6 and the lumps of the swarf are transferred to the centrifuge by the swap conveyor 8.

The swarf is also recovered by the filter conveyor 14 installed at the bottom of the filter tank 18 toward the centrifuge, and the abrasive oil is transferred from the filter tank 12 to the clean tank 18 by the recovery pump 16. In the clean tank 18, a repetitive process is performed through the supply pump 20 to the polishing cabin along the supply line.

Then, as shown in FIG. 2, the swarf passed through the centrifuge flows into the swab block 48 along the swarf supply line 42 and is loaded by the motor 56 and the screw 52 installed on the side thereof. It is inserted into the interior of 84.

Of course, the swap is supplied to the inside of the load case 84 in a state in which the swap supply gate 58 is open, and after a certain time, the swap supply gate 58 is closed to block the supply of the swap.

The swap supplied to the rod case 84 is compressed by the operation of the ram cylinder 88, wherein the rod position of the ram cylinder 88 is advanced to the position of the compression sensor 90a, and the cylinder 94 As the load of is moved to the position of the down sensor 94b and the gate block 96 moves to the bottom of the gate block box 92, the left side of the load case 84 is blocked.

In addition, the door 98 is opened by the cylinder 102 so that the abrasive oil adhered to the swarf is discharged when the swarf is compressed, and the crushed abrasive oil passes through the oil hole 96a to allow the abrasive oil to be discharged. It builds up on the inner bottom and then flows back through the oil drain line 104 to the filtering device.

When this primary compression is finished, the motor 72 of the pellet material supply cylinder 66 is operated to operate the screw 68 while the swarf supply gate 58 is closed and the pellet material supply gate 74 is opened. Rotate

As a result, the burnt ashes CP filled in the burnt ash storage block 64 are supplied into the rod case 84.

When the predetermined coal ash CP is supplied, the coal ash supply gate 74 moves to the position of the cross sensor 76b by the operation of the cylinder 76, and the ram cylinder 88 is moved to the position of the compression sensor 90a. Advance to compress the pellets (CP) on the back of the swap gasket (SK).

In this process, the door 98 enters the interior of the gate block 96 by the cylinder 102 to prevent the addition of the carbon material into the abrasive oil, and thus the oil hole 96a is blocked. In addition, the burnt material supply gate 74 is also closed to block the supply of the burnt material CP.

When the compression of the burnt material CP is completed, the whole of the gate block 96 is raised by the upward motion of the cylinder 94 installed inside the gate block box 92, and then the ram cylinder 88 is operated again to extract the sensor. When it moves to the position of 90b, the swap cake SK in which the burnt material CP was compressed together is extracted to the outside of the rod case 84, and is thrown into the cake box B. As shown to FIG.

As described above, the embodiment of the present invention substantially solves the conventional problems.

That is, the swarf produced as a by-product can be reduced and recycled by removing the abrasive oil contained therein by compression.

And since the swarf is made of cake together with the charcoal ash and then put into the electric furnace of the steelmaking plant, dissolution is triggered by the charcoal ash during the melting of the swarf, so that the dissolution proceeds quickly, thereby shortening the dissolution time.

Therefore, it is possible to solve the problem of the temperature drop inside the furnace, excessive power consumption, and poor slag composition.
