CONTAINER APPARATUS AND MOLTEN MATERIAL TRANSPORTING METHOD

The present invention relates to a vessel apparatus and a method for transporting a melt, and more particularly, to a vessel device and a method for transporting a melt capable of preventing the melt from overflowing from the apparatus.

Typically, containers and cranes are used to transport the melt during the iron making process. For example, the melt is accommodated in a container, and the container is hoisted by a crane and transported to a desired location.

When transporting the melt, the crane travels along the installed rail at a high distance from the ground. At this time, if an abnormality occurs in the traveling device and rail of the crane, the crane may be braked abruptly. In this case, the melt is focused in the traveling direction due to inertia, and bubble burst and scattering of the melt may occur due to the concentration of the melt. Also, if the pull is severe, the melt may overflow the top of the vessel and fall to the ground.

The technology underlying the present invention is disclosed in the following patent documents.

The transporter (H) may be coupled to the container unit 100 and may be a variety of transport devices capable of moving the container unit 100 upward. Here, the upward movement refers to a series of movements that rise to a predetermined height from the ground or the floor of the workplace, move a predetermined distance in the horizontal direction, and descend from a desired position. At this time, lifting may be referred to as hoisting, and movement may be referred to as transport or transfer.

For example, the carrier H may include an overhead crane. The transporter (H) may be provided on the transport path of the melt (M). The carrier H may include a main winding hook, a winding hook (not shown), a traveling device (not shown) and a hoisting device (not shown). The traveling device may include a rail and a vehicle body. The hoisting device may include a wire drum, a motor and a wire rope. The hoisting device may be installed on the vehicle body.

The bottom plate may extend in the horizontal direction, and the side wall may extend in the vertical direction (Y). The horizontal direction may include a left-right direction (X) and a front-rear direction (Z). For example, the bottom plate may have a disk shape, and the side wall may have a hollow cylindrical shape. Of course, the shape of the bottom plate and the side wall may vary. In addition, the bottom plate and the side wall may be referred to as a shell. A refractory material may be built on the upper surface of the bottom plate and the inner surface of the side wall. A space capable of accommodating the melt M may be defined by the bottom plate and the sidewall.

The above-described container unit 100 may be referred to as a ladle. The container part 100 may have an upper portion open upward. The melt (M) may be injected into the interior of the container part 100 through the opening of the upper part of the container part (100).

1 and 4 , an installation groove 500 and a connection groove 600 may be formed in the container part 100 according to the first embodiment of the present invention. The installation groove 500 is formed through at least an upper portion of the side wall of the container part 100 in the vertical direction (Y) to accommodate the cover part 300 , and extends along the circumference of the side wall of the container part 100 . can be That is, the installation groove 500 may be formed inside the side wall of the container unit 100 .

Here, the upper portion of the installation groove 500 may be opened upward from the upper end 100a of the side wall of the container unit 100 . Therefore, the upper opening of the installation groove 500 may be formed in the upper end (100a) of the side wall of the container unit (100). That is, the cover part 300 may protrude upward from the side wall of the container part 100 through the upper opening of the installation groove 500 . In addition, the cover part 300 may be accommodated inside the side wall of the container part 100 .

Here, the upper portion of the side wall of the container part 100 may be defined based on the locking part 200 . That is, the upper portion of the side wall of the container part 100 means an upper region of the side wall of the container part 100 higher than the engaging part 200 . The remaining area of the side wall of the container part 100 except for the upper part of the side wall of the container part 100 may be defined as the lower part of the side wall of the container part 100 . Of course, the lower bottom surface of the installation groove 500 may be located below the side wall of the container unit (100).

The depth from the upper opening of the installation groove 500 to the lower bottom surface is referred to as the depth in the vertical direction (Y) of the installation groove 500 . A depth in the vertical direction Y of the installation groove 500 may be greater than or equal to a length in the vertical direction Y of the cover part 300 . Preferably, the depth in the vertical direction (Y) of the installation groove part 500 may be the same as the length in the vertical direction (Y) of the cover part 300 . Accordingly, when the cover unit 300 is accommodated in the installation groove 500 , the upper surface of the cover unit 300 and the upper end 100a of the side wall of the container unit 100 may have the same height. That is, the upper surface of the cover part 300 and the upper end 100a of the side wall of the container part 100 may be located on the same plane.

Accordingly, when the cover part 300 is accommodated in the installation groove 500 , the cover part 300 may not protrude upward of the container part 100 . Therefore, when the carrier (H) does not move the container part 100 upward, the cover part 300 can be safely stored in the sidewall of the container part 100 . Meanwhile, the depth of the installation groove 500 in the vertical direction (Y) may be smaller than the length of the sidewall of the container unit 100 in the vertical direction (Y).

The connection groove 600 may be formed to penetrate the sidewall of the container unit 100 in the horizontal direction, specifically, in the left-right direction (X). Here, the direction in which the connection groove 600 penetrates may differ depending on the direction in which the locking part 200 is disposed. That is, when the locking part 200 is disposed on both left and right sides of the container part 100 , the connection groove 600 penetrates the side walls in the left and right sides of the container part 100 in the left and right direction (X), and the locking part 200 . When disposed on both front and rear sides of the container unit 100 , the connection groove 600 may penetrate the sidewalls in the front and rear directions (Z) at both front and rear sides of the container unit 100 .

The connection groove 600 may be formed on both sides of the upper side of the locking part 200 and the left and right direction (X) of the container part 100 . And the connection groove 600 may be formed to penetrate a part of the side wall of the container unit 100 in the left and right direction (X). That is, the connection groove 600 may extend by a predetermined thickness in the left-right direction (X) from the outer surface of the side wall of the container unit 100 , and may be spaced apart from the inner surface of the side wall of the container unit 100 . For example, the connection groove 600 may extend from the outer surface of the side wall of the container part 100 to the installation groove 500 . Accordingly, the installation groove 500 may be exposed to the outside of the container unit 100 through the connection groove 600 . Here, the connection groove 600 may communicate with at least a lower portion of the installation groove 500 . The driving unit 400 may be disposed in the connection groove 600 . That is, the driving unit 400 may be connected to the cover unit 300 through the connection groove 600 . The driving unit 400 moves up and down inside the connection groove 600 and can adjust the height of the cover unit 300 .

The side opening of the connection groove 600 may be spaced apart from the upper side of the locking part 200 and located on the outer surface of the side wall of the container part 100 . That is, the connection groove 600 may be closer to the upper end 100a of the sidewall of the container part 100 than the locking part 200 . Of course, the position of the connection groove 600 may be different depending on the depth of the installation groove 500 . Here, the outer surface of the side wall may be a surface facing the outside of the container unit 100, the inner surface of the side wall may be a surface facing the melt (M) inside the container portion (100).

The length of the connection groove 600 in the vertical direction Y may be greater than or equal to the height at which the cover part 300 protrudes. Accordingly, when the cover part 300 protrudes, it is possible to prevent the connection groove 600 and the driving part 400 from interfering with each other. On the other hand, the length of the vertical direction (Y) of the connection groove 600 may be less than or equal to the length of the installation groove 500 in the vertical direction (Y).

1 and 2 , the locking part 200 may be respectively mounted on the outer surface of the side wall of the container part 100 on both sides in the left and right direction (X) of the container part 100 . The locking part 200 may be coupled to the main winding hook of the carrier (H). That the locking part 200 is coupled to the main winding hook means that the lower surface of the locking part 200 and the main winding hook are brought into contact by inserting the locking part 200 into the ring portion of the main winding hook.

The main winding hook of the carrier (H) may be supported on the traveling device of the carrier (H) through a wire rope and a wire drum (not shown). When the winding hook is raised by winding the wire rope around the wire drum, the holding part 200 and the container part 100 can be raised. By driving the traveling device along the transport path of the melt (M), the container unit 100 may be moved, and the melt (M) may be transported. When the wire rope is released from the wire drum to lower the winding hook, the holding part 200 and the container part 100 can be lowered. The lower portion of the container unit 100 may be provided with a bogwon hanger (not shown). When the bogwon hook of the carrier (H) lifts the bogwon hook, the container unit 100 can be tilted.

While transporting the container unit 100 to the transporter (H), the traveling device may perform abrupt braking. Accordingly, the melt (M) inside the container unit 100 may be focused in the direction in which the traveling device was traveling due to inertia, for example, in the front-rear direction (Z), and the molten material M may fluctuate and scattering may occur. . At this time, by using the cover part 300, the melt (M) overflowing the upper end (100a) of the side wall of the container part 100 and falling to the ground, it is possible to prevent the falling product from falling to the ground.

That is, in the container device according to the first embodiment of the present invention, the melt (M) does not overflow the upper end (100a) of the side wall of the container part (100), and the scattering product of the melt (M) is the container part (100). In order not to fall to the surroundings, the cover part 300 that can protrude upward from the sidewall of the container part 100 during the upward movement of the container part 100 using the transporter (H), and pulling of the transporter (H) A driving unit 400 capable of protruding the cover unit 300 by using it may be provided.

1 to 3 , the cover part 300 may be accommodated in the installation groove 500 when the locking part 200 and the main winding hook of the carrier H are separated, and the locking part 200 and When the main winding hook of the carrier (H) is coupled, it may protrude from the installation groove 500 . Here, as the cover part 300 protrudes, the metal attached to the upper end 100a of the side wall of the container part 100 may be removed.

The cover part 300 extends continuously along the circumference of the side wall of the container part 100 so that the upper surface is exposed upward of the installation groove 500 and the outer surface is exposed to the side of the connection groove 600 . can be For example, the cover part 300 may have an inner diameter greater than the inner diameter of the side wall of the container part 100 and an outer diameter smaller than the outer diameter of the side wall of the container part 100 , and extend continuously along the perimeter of the side wall of the container part 100 . It may be formed in a hollow shape.

The height at which the cover part 300 protrudes from the container part 100 may be greater than the overflow height of the melt (M). Here, the overflow height of the melt (M) may be a height at which the molten material (M) is raised from the upper end (100a) of the side wall of the container part (100) by the sloshing of the melt (M) when the speed of the carrier (H) is changed. The overflow height may vary depending on the operating speed of the carrier (H), the viscosity of the melt (M), and the shape of the container part (100). This overflow height may be obtained empirically by repeating the process or may be derived using computer simulation.

At least a lower portion of the cover unit 300 may be exposed to the connection groove 600 and may be connected to the driving unit 400 . The length of the cover part 300 in the vertical direction (Y) may be greater than a height difference between the lower part of the connection groove 600 and the upper end 100a of the side wall of the container part 100 . The length of the cover part 300 in the vertical direction (Y) may be less than or equal to the depth of the installation groove 500 in the vertical direction (Y).

When the cover part 300 protrudes, its upper surface may protrude by a predetermined height (L) from the upper end 100a of the side wall of the container part 100 . Therefore, even if the height of the side wall of the container part 100 is not permanently increased, for example, even if the size of the container part 100 is not increased, the total height of the container part 100 only during the upward movement of the container part 100 . can be increased, and overflow of the melt (M) can be prevented by this height increase. In this case, the structure of the driving unit 400 for protruding the cover unit 300 may be varied.

5 and 6, the driving unit 400 according to the first embodiment of the present invention may be connected to the cover unit 300 through the connection groove 600 so as to protrude the cover unit 300, It may be installed on the locking part 200 . The driving unit 400 may be installed on both sides of the container unit 100 in the left-right direction (X), respectively.

The driving unit 400 is disposed to pass through the engaging portion 200 in the vertical direction (Y), and the lifting bar 410 that can be raised in contact with the carrier (H), and the container portion from the upper portion of the lifting bar 410 . It may include a connecting bar 420 extending in a direction toward the sidewall of 100 , disposed to penetrate through the connecting groove 600 , and connected to the cover unit 300 . Accordingly, the driving unit 400 may be associated with the carrier (H) and may protrude upward from the sidewall of the container unit 100 by using the upward movement of the carrier (H).

The lifting bar 410 is disposed to pass through the locking part 200 , and an upper portion may protrude upward of the locking part 200 , and a lower portion may protrude downward of the locking part 200 . And the lifting bar 410 may have a different degree of protrusion of the upper and lower portions according to the height of the carrier (H).

A length in the vertical direction Y of the lifting bar 410 may be greater than a height difference between the lower surface of the connecting groove 600 and the lower surface of the engaging part 200 . That is, when the connecting bar 420 is positioned under the connecting groove 600 , the lower portion of the lifting bar 410 may protrude downward from the engaging portion 200 . For example, the length of the lifting bar 410 protruding downward of the engaging portion 200 when the carrier (H) and the engaging portion 200 is separated from the carrier (H) is the cover portion when the carrier (H) and the engaging portion 200 are combined. It may be the same as the height (L) at which 300 protrudes. That is, the cover part 300 may protrude upward from the upper end 100a of the side wall of the container part 100 by the protrusion length of the lower part of the lifting bar 420 .

The connecting bar 420 extends in the left and right direction (X), one end may be connected to the lower portion of the cover unit 300 inside the connecting groove 600 , and the other end opposite to the one end is the upper portion of the elevating bar 410 . can be connected with The connection bar 420 may transmit the movement of the lifting bar 410 in the vertical direction Y to the cover unit 300 .

The operation of the container device according to an embodiment of the present invention will be described below. Referring to FIGS. 2 and 5 , the main winding hook of the carrier H moves forward (+Z) toward the container part 100 and may be located below the locking part 200 .

The locking part 200 and the carrier H are separated from each other, and the lower part of the lifting bar 410 may protrude to the lower side of the locking part 200 by the weight of the lifting bar 410 . The connection bar 420 may be located under the connection groove 600 , and the cover part 300 may be accommodated in the installation groove 500 .

Then, referring to FIGS. 3 and 6 , the main winding hook of the carrier H rises (+Y) to contact the lower surface of the engaging part 200, and the lower part of the elevating bar 410 is raised, and the elevating bar An upper portion of the 410 may be raised to a predetermined height from the engaging portion 200 . And the connection bar 420 may rise from the lower part to the upper part of the connection groove part 500 , and the cover part 300 may protrude from the installation groove 500 .

That is, when the engaging portion 200 and the carrier (H) are coupled, the carrier (H) pulls the lower portion of the lifting bar 410 upward, and thus, the lifting bar 410 from the upper side of the engaging portion 200 . The protrusion length of the upper part of the can be increased. In this case, the lower portion of the lifting bar 410 may be located inside the locking part 200 . In addition, the connection bar 420 may be positioned above the connection groove 600 , and the cover part 300 may protrude upward from the installation groove 500 .

As such, the driving unit 400 can transmit the upward movement of the carrier (H) to the cover unit 300 as it is, and by coupling the carrier (H) to the engaging unit 200, the cover unit 300 is moved to the container unit ( 100) can be rapidly protruded upward from the side wall. Thereafter, while the container part 100 is moved upward by the carrier H, the cover part 300 may maintain a state protruding from the upper end 100a of the side wall of the container part 100 .

As the cover part 300 protrudes to a predetermined height L from the upper end 100a of the side wall of the container part 100, the overall height (L0 + L) of the container part 100 increases, so that the melt (M) Even if the hot water surface rises higher than the height L0 of the side wall of the container part 100 , the cover part 300 can prevent overflow of the molten material M. Accordingly, even if the traveling device is suddenly stopped while the traveling device of the carrier (H) is driven to move the container part 100 upward, the melt (M) inside the container part 100 is transferred to the container part by the cover part 300 . Overflowing the top 100a of the sidewall of 100 can be prevented.

On the other hand, referring to FIG. 1 , in the container device, a support ring 700 is formed by winding around the side wall of the container part 100 between the connection groove 600 and the locking part 200 so that the connection bar 420 can be seated. ) may be further included. By using the support ring 700 , the connection bar 420 can be stably supported when the cover part 300 is returned. The return of the cover part 300 means that the cover part 300 is accommodated in the installation groove 500 .

And the container device may further include a buffer part 800 that is mounted on the lower bottom surface of the installation groove 500 and can be in contact with the cover part 300 . The buffer unit 800 may be, for example, a pad made of an elastic material. In this case, the elastic material may include a rubber material. In addition, the buffer 800 may include a spring member. For example, the type of the buffer 800 may be various.
