Description

Apparatus for casting aluminum ingot continuously}

The present invention relates to an aluminum ingot casting apparatus, and more particularly, to an aluminum ingot continuous casting apparatus capable of continuously casting aluminum ingots of different weights in one line.

In recent years, aluminum alloys using aluminum have superior castability, workability, and specific strength than other metals, and are widely used as various structural materials and mechanical parts, and their use is gradually increasing. In particular, aluminum alloys are cost-effective. It is a burden in the industry, but since it can produce ultra-lightweight structural materials and parts, its use is increasing.

However, in the case of disposing of aluminum as the main material such as cans, chassis pieces, engine blocks, ships, and airplane parts, it is common to recycle and recycle with pure aluminum.

The method of regenerating waste aluminum is to dissolve the collected various waste aluminum to remove oxides, add alloying materials such as iron, manganese, copper, silicon, zinc, etc. according to the composition of the final aluminum material to be regenerated. The molten metal is put into a mold, cast and molded into an internationally standardized ingot, and recycled.

In the process of regenerating such waste aluminum, first, the collected waste aluminum is put into an aluminum melting furnace to dissolve chips, scraps, or crushed material with high heat of about 1000 to 1100°C.

In general, the molten aluminum molten metal in a melting furnace is transferred to an alloy furnace, and the alloy material is appropriately added in a ratio suitable for the intended use, thereby making an aluminum alloy molten metal.

The molten metal melted in the alloy furnace can be directly sent to the casting machine for forming the ingot or stored in the molten metal feed ladle and transferred to another place.

Alternatively, it can be stored to maintain the state of molten metal in a warming furnace (holding furnace) and then sent to a casting machine or injected into the molten metal feed ladle.

1 is a view showing a conventional general aluminum ingot continuous casting apparatus.

Specifically, "the molten aluminum is filled in the ingot casting mold arranged on the conveyor part 3 through the melt distributor 1, and the conveyor part 3 is removed by the motor and drive sprocket 4 on the right side. In a horizontal continuous casting machine that transfers at a constant speed, the ingot casting mold is an aeropin mold (2), with a plurality of pins (8) attached to the bottom at regular intervals, and arranged on the conveyor part (3). Blowing air units 5 and 5 ′ serving as air supply fans above and below the aeropin mold 2 are installed and arranged, respectively, and an aeropin mold 2 is placed on the conveyor unit 3. A suction air part (7) is installed and arranged to exhaust the high-temperature air generated by cooling the hot aluminum molten metal and the aeropin mold (2) by covering the blowing air parts (5, 5') arranged as a medium. An aluminum horizontal ingot continuous casting machine characterized by" is known.

However, in the case of conventional continuous casting machines, the same ingot casting molds are arranged and transferred. In other words, only one type of ingot having the same weight and shape is cast in one continuous casting machine.

If, in order to cast different types of ingots, different continuous casting machines must be operated. This has the disadvantage of taking up twice the space in the factory and increasing the difficulty of management and maintenance.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

For reference, the description with reference to the drawings is for easier understanding of the present invention, and the scope of the present invention is not limited thereto. Further, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, a detailed description will be omitted.

2 is a side view showing the overall structure of an aluminum ingot continuous casting apparatus according to an embodiment of the present invention, and FIG. 3 is a plan view of the present invention shown in FIG.

The present invention relates to an invention having a structure capable of continuously casting aluminum ingots of different weights in one casting apparatus, and largely, a conveyor part 100, an ingot casting mold 200, and a molten metal distribution part 300 ) Can be included.

First, the conveyor unit 100 will be described together.

The conveyor unit 100 is provided with driving sprockets 120 rotating at both ends, and a chain is wound around both driving sprockets 120 and driven in a caterpillar track.

The driving sprocket 120 rotates by a separate driving motor 130, and is controlled to rotate at a constant speed.

In this case, the conveyor unit 100 may include a horizontal conveyor 100a disposed horizontally and an inclined conveyor 100b disposed inclined upward.

A driving motor is interlocked to the driving sprocket 120 installed on the upper end of the inclined conveyor 100b to be driven, and the molten metal distribution unit 300 described later is provided at one end of the horizontal conveyor 100a.

In addition, a plurality of ingot casting molds 200 are arranged and combined in a line and transferred to the conveyor unit 100 across the conveyor unit 100.

Since the conveyor unit 100 is a technique well known in the field of aluminum ingot continuous casting machines, detailed descriptions will be omitted.

Next, the ingot casting mold 200 will be described. For reference, it should be noted that, in Figs. 2 and 3, the ingot casting mold is not shown in the whole section of the chain, but only a part is shown.

The ingot casting mold 200 is a molding frame capable of making an ingot by accommodating molten aluminum.

In the present invention, the ingot casting molds 200 are not all the same, but referring to the enlarged view in FIG. 3, the first mold 210 so as to be able to cast different types of ingots having different shapes and weights. It is preferable that the and second molds 220 are alternately arranged alternately.

That is, a first mold 210 for casting an ingot having a relatively heavy weight and shape and a second mold 220 for casting an ingot having a relatively light weight and shape are provided.

For example, a first aluminum ingot may be cast in the first mold 210, and a second aluminum ingot may be cast in the second mold 220. The first aluminum ingot and the second aluminum ingot have different weights and shapes.

The ingot casting mold 200 is disposed between the rollers 140 that are each successive.

Therefore, when casting the first aluminum ingot, the molten aluminum metal is continuously injected into only the first mold 210 and not into the second mold 220, thereby continuously producing the first aluminum ingot.

If, when casting the second aluminum ingot, aluminum molten metal is continuously injected into only the second mold 220 and not injected into the first mold 210, so that the second aluminum ingot can be continuously produced.

As a result, the present invention is capable of continuously producing aluminum ingots having different weights and shapes as needed in one continuous casting apparatus.

The distribution of the molten metal is implemented by the molten metal distribution unit 300 to be described later.

Next, the molten metal distribution unit will be described with reference to FIGS. 4 and 5 together. 4 is a plan view showing the structure of the molten metal distribution unit of the present invention shown in FIG. 2, and FIG. 5 is a side view of the molten metal distribution unit of the present invention shown in FIG.

The molten metal distribution unit 300 is configured to inject a certain amount of molten aluminum into each of the ingot casting molds 200 to be transferred, and includes a support frame 310, a rotating shaft 320, a housing 330, a distribution port 340, It may be configured to include a transmission sprocket 350.

The support frame 310 supports the molten metal distribution unit 300 to be installed on the top of the conveyor unit 100 and may be configured with a transverse support 311 and a longitudinal support 312.

The transverse support 311 is installed to be spaced apart from each other while crossing the conveyor unit 100 on one side of the conveyor unit 100, and the longitudinal support 312 is spaced apart from the conveyor unit 100 It is installed along the longitudinal direction of, and is coupled to the transverse support 311 at a right angle. At this time, the transverse support 311 and the vertical support 312 may have a square beam shape.

In addition, the longitudinal support 312 is installed while the rotation shaft 320 is rotatably supported. At this time, the rotation shaft 320 is in the same direction as the transverse support 311.

In addition, the housing 330 is coupled to one end of the rotation shaft 320 and rotates together.

As shown, the housing 330 may be formed in a cylindrical container shape to accommodate molten metal therein. And the housing 330 is connected to the hot water supply so that the aluminum molten metal can be supplied. Accordingly, the molten metal transferred along the bath is introduced into the housing 330.

Here, a distribution hole 340 protrudes and is formed on the outer periphery of the housing 330.

A plurality of the distribution ports 340 are formed at regular intervals, and the distribution ports 340 positioned at the lowermost side are disposed adjacent to the ingot casting mold 200.

Meanwhile, the transmission sprocket 350 is coupled to the other end of the rotation shaft 320 and rotates together.

The transmission sprocket 350 has a plurality of locking pins 351 radially formed on the outer periphery of a circular flat plate at regular intervals. The gap between the locking pins 351 is formed equal to the width of the ingot casting mold 200, and each locking pin 351 is caught while being inserted between the ingot casting mold 200.

Therefore, when the ingot casting mold 200 moves horizontally, the locking pin 351 inserted and caught between the ingot casting mold 200 is pushed, so that the transmission sprocket 350 is rotated by applying a rotational force (torque). Is done.

Further, the rotational force applied to the transmission sprocket 350 is transmitted through the rotation shaft to rotate the housing 330 as well. That is, the housing 330 is not driven by itself, but rotates in connection with the transfer of the ingot casting mold 200.

At this time, since the molten metal must be injected through the distribution port 340 while the ingot casting mold 200 is moved in a state sandwiched between two adjacent locking pins 351, as shown in FIG. The distribution port 340 is formed to be positioned between the locking pins 351.

However, in the present invention, the molten metal is continuously injected into only one of the first and second molds 210 and 220 which are alternately arranged in the ingot casting mold 200. To this end, it is preferable that the distribution port 340 is formed so as not to be positioned between all adjacent locking pins 351 but to be positioned across one by one.

Specifically, as shown, a portion in which the distribution hole 340 is located and a portion without the distribution hole 340 are alternately formed between the adjacent locking pins 351. That is, the two locking pins 351 adjacent between the two distribution ports 340 are disposed to be positioned.

Because of this structure, the molten metal is injected into one of the ingot casting molds 200, and the molten metal is not injected into the other ingot casting mold 200, so that only one weight of ingot can be continuously produced.

In addition, if production of another ingot casting mold 200 is required, the position of the distribution port 340 is changed so that the molten metal is injected only into the other ingot casting mold 200 so that only other types of ingots can be produced.

For the above adjustment, it is preferable that the longitudinal support 312 is rotatably coupled to the transverse support 311 in the present invention.

In other words, one end of the longitudinal support 312 is hinged to any one of the two transverse supports 311 using a feldspar 313, and the other end is not coupled and is in a state where the longitudinal support 312 It is a structure that can be lifted by holding the other end of ).

By doing this, the housing 330, the rotation shaft 320, and the transmission sprocket 350 installed on the longitudinal support 312 are all lifted, and in this state, a distribution port located on any one of the ingot casting molds 200 It can be adjusted by rotating the rotation shaft 320 so that the 340 is located in another ingot casting mold 200.

Here, a handle 360 may be further formed at the other end of the longitudinal support 312 so that an operator can hold and lift the longitudinal support 312.

Hereinafter, the operating state of the present invention will be described with reference to FIGS. 6 and 7 together.

Figure 6 is a state diagram of the operation of the present invention, Figure 7 is a state diagram showing a state of replacing the ingot casting mold of the present invention.

First, a process of injecting molten metal into only the first mold 210 to produce the first aluminum ingot will be described.

First, when the driving sprocket 120 rotates at a constant speed by driving of the driving motor 130, the chains 110 move.

So, each ingot casting mold 200 fixed to the chain 110 is also transferred along the chain 110, and thus the transmission sprocket 350 of the molten metal distribution unit 300 interlocked also starts to rotate. do.

When the housing 330 is rotated by the rotation of the transmission sprocket 350 and at the same time, when the molten metal flows into the housing 330 along the hot water channel, the molten metal is discharged through the distribution port 340 and reaches the lower side. A molten metal is injected into the first mold 210 (see Fig. 6(a)).

When the molten metal is injected into the first mold 210 and transferred horizontally, the second mold 220 is subsequently transferred and is located directly under the housing 330, at this time, corresponding to the second mold 220 Since there is no distribution port 340 at the location, molten metal cannot be injected (see Fig. 6(b)).

Accordingly, the second mold 220 passes without injection of the molten metal, and the other first mold 210 that is subsequently transferred is located directly under the housing 330, in which case through the distribution port 340 The molten metal is injected.

In this way, only the first mold 210 is injected with molten metal to produce only the first aluminum ingot.

If, in order to produce the second aluminum ingot, the operator stops driving the drive motor 130, grabs the handle 360 and rotates the end support 312 to lift the housing 330 and As the rotation shaft 320 and the transmission sprocket 350 rise, the locking pins 351 inserted between the ingot casting mold 200 are removed (see FIG. 7).

In the state in which the locking pin 351 is removed, the rotation shaft 320 is slightly rotated to adjust the distribution port 340 to correspond to the second mold 220, and then the longitudinal support 312 is lowered. Put it back.

Then, when the locking pin 351 is again inserted between the ingot casting mold 200 and the ingot casting mold 200 is transferred, the distribution port 340 is continuously adjacent to the second mold 220 Therefore, the molten metal may be injected only into the second mold 220.

Although the exemplary embodiments of the present invention have been described above with reference to the drawings, a person of ordinary skill in the field to which the present invention belongs will be able to perform various applications and modifications within the scope of the present invention based on the above contents. Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should not be determined by the claims to be described later, but also by those equivalents to the claims.
