Description

Torpedo ladle car with a sliding cover

The present invention relates to a torpedo ladle car, each of which has a trolley coupled to both ends of the torpedo ladle in order to transport molten iron produced in the blast furnace to the steelmaking process, and more specifically, to make the molten iron received from the blast furnace. A sliding cover is provided at the molten iron inlet of the torpedo ladle which is temporarily stored for transportation to the process, but a scraper that can be removed from the molten iron inlet on the front of the cover, and the molten iron is removed from the molten iron in the cover rail when discharging the molten iron. A rail cover is provided to prevent the cover from being attached, and the cover actuating means for moving the sliding cover can be connected to the cover or separated from the cover as necessary in a state where the cover operating means is installed in the bogie rather than the torpedo ladle. The present invention relates to a topedo ladle car provided with a sliding cover, wherein the topedo ladle is free to rotate.

Steel is made through the sequential steel making process and steel making process. The steel making process is a process of mixing iron ore, coke, limestone, etc. in a blast furnace, also called a blast furnace, to obtain molten iron, molten iron. Process of obtaining molten steel in molten state with composition suitable for final purpose by adjusting components such as C, Si, Mn, P, S, etc. As a result, steel is made by casting molten steel.

However, the molten iron produced in the blast furnace is transferred to the topedo ladle car, which is a means for transporting the molten iron, and then transferred to the steelmaking process, where the desulfurization treatment is performed as a preliminary treatment for steelmaking. As shown in FIG. 1, the fedo ladle car includes a topedo ladle 11 having a shape similar to that of a torpedo by gradually decreasing the cross-sectional area toward both sides in a longitudinal direction from a central portion having a constant cross-sectional area; It is rotatably coupled to both ends of the torpedo ladle 11, and is composed of a pair of trolleys 12, etc. moving on the main rail.

The torpedo ladle car, as described above, carries molten iron, molten pig iron, produced at the blast furnace to the steelmaking plant. The temperature of the molten iron at the blast furnace is about 1500 ° C. The temperature drop phenomenon of the molten iron is mainly due to the heat loss through the molten iron inlet provided in the upper center of the torpedo ladle and the difference in temperature drop is large due to various conditions.

This is because the elliptical molten iron inlet provided at the center of the toppedal ladle is always open, and the temperature of the molten iron decreases as the heat of the molten iron is dissipated out of the torpedo ladle through the molten iron inlet.

In addition, when the torpedo ladle car moves to the blast furnace to refill the molten iron after discharging the molten iron from the steelmaking plant, the internal temperature of the torpedo ladle continues to dissipate as heat is released to the outside through the molten iron inlet. Will fall.

In other words, in the case of the tolerance in which the molten iron is completely discharged, the internal temperature of the torpedo ladle may drop by about 100 ° C per hour, and when the molten iron is completely filled, the temperature of the molten iron drops by about 10 ° C per hour. The temperature drop of the molten iron can be reduced only by minimizing the internal temperature drop of the molten iron during the tolerance rather than the melting temperature of zero.

The reason for reducing the temperature drop of the molten iron as described above is as follows.

In steelmaking, molten iron is injected with oxygen at a high pressure in order to reduce the carbon content. In this case, the temperature of molten steel in which carbon is reduced by a strong oxidation reaction is increased to about 1700 ° C.

However, as described above, if the molten steel temperature is higher than necessary after the blowing with high pressure oxygen, the molten steel is cooled because continuous casting operation is not possible. At this time, the coolant is used as a general iron scrap. At the same time as the temperature decreases, the amount of molten steel increases.

In other words, the higher the temperature of the molten iron, more iron scrap can be administered, so the steelmaking efficiency can be improved and the steelmaking cost can be reduced, so the temperature drop of the molten iron should be minimized. The temperature drop inside the field must first be reduced.

Therefore, in order to minimize the temperature drop of the molten iron, it is desirable to combine the cover with the molten iron inlet of the torpedo ladle. The simplest cover is a detachable cover separately formed from the torpedo ladle, where the molten iron is injected or discharged. The cover can be attached to the molten iron inlet by a crane and the like by lifting the cover with the crane.

However, when the cover is used, the molten iron has solidified in the state of injecting, transporting and discharging the hot molten iron, or flowing the molten iron to the outside of the torpedo ladle in the process of preliminary treatment. As a result, the cover and the molten iron inlet may not be in close contact with each other, thereby reducing the warming effect.

Therefore, when the cover is used for the torpedo ladle, there is a need to remove the current around the molten iron inlet from time to time.

In addition, the sliding cover can be directly coupled to the topedo ladle without using a crane. In this case, the molten iron is attached to the rail for moving the cover when discharging the molten iron, which may damage the cover device. There is a problem that constraints are applied to the rotation of the fedo ladle.

As for the Topedo ladle car provided with the sliding cover, "Topedo Ladle Car with a lid" is published in Japanese Laid-Open Utility Model S52-84908.

The torpedo ladle car, a hydraulic cylinder is installed on the outer surface of one side end inclined portion of the topedo ladle, the hydraulic cylinder is a structure for sliding opening and closing the lid (corresponding to the "cover"), removable by a crane While there is an advantage over the cover, the hydraulic cylinder and the bogie interfere with each other when rotating the torpedo ladle to discharge the molten iron, thereby limiting the rotation of the topedo ladle.

In other words, the torpedo ladle car rotates the torpedo ladle 130 ° with respect to the bogie when it follows the charter in the steel mill or the shipyard, and the charter ship is discharged from the charter inlet. The torpedo ladle may be rotated in both directions by 180 °. When the cover actuating means for actuating the cover is inclined to the inclined portion of the topedo ladle, the cover actuating means may interfere with the balance. Since the rotation of the torpedo ladle is limited, complete and smooth discharge of the molten iron becomes impossible.

The present invention provides a torpedo ladle car having a large temperature drop inside the torpedo ladle during a temperature drop and a tolerance of the molten iron during transportation of the molten iron; Topedo ladle car which must be removed repeatedly around the molten iron inlet when the cover is provided; If the cover is a sliding structure cover operation means is installed on the outer surface of the one end of the torpedo ladle to interference with the trolley torpedo ladle car that can not be freely rotated of the torpedo ladle; It is designed to solve all the problems of the conventional torpedo ladle cars, etc., and has a sliding cover, such as a topedo ladle car without a cover, for free rotation of the torpedo ladle, i. It is an object of the present invention to provide a topedo ladle car with no limitations.

It is another object of the present invention to provide a topedo ladle car which can now be automatically removed when attached to the outer surface around the molten iron inlet when the cover is slid.

In addition, it is another object of the present invention to provide a torpedo ladle car which does not cause the molten iron to splash or flow over the moving rail when the molten iron is discharged.

The object of the present invention, the sliding cover for the molten iron inlet coupled to the reciprocating movement on the outer surface of the Topedo ladle, the cover operating means that is repeatedly detachably coupled to the cover in the state installed on the trolley, both ends of the cover The rail cover and the cover are respectively coupled to one end of the cover is now achieved by a removal scraper or the like.

Topedo ladle car with a sliding cover of the present invention, the cover operating means for reciprocating the sliding cover is detachable from the cover at the same time the bar is installed on the bogie, not the torpedo ladle, sliding the cover to open the molten iron inlet By separating the cover operating means from the cover in one state, there is an advantage that free tilting, that is, free rotation of the torpedo ladle, like a conventional torpedo ladle car without a cover, despite the presence of the cover.

In addition, after discharging the molten iron, the scraper coupled to the cover automatically removes the current around the molten iron inlet during the process of reconnecting the cover operation means to the cover and then moving the cover to cover the molten iron inlet. There is no need to perform a separate removal now to remove the now, there is an advantage that the heat loss is reduced because there is no gap between the cover and the molten iron inlet.

In addition, since the rail cover moving together with the cover on both sides of the cover is combined, the molten iron does not splash or flow on the rail when discharging the molten metal, which does not cause a malfunction or damage to the cover.

The present invention relates to a topedo ladle car having a sliding cover capable of repeatedly opening and closing the molten iron inlet of the topedo ladle.

In the torpedo ladle car provided with the sliding cover of the present invention, the cover operation means for reciprocating the molten iron inlet opening and closing cover is fixedly coupled to the bogie rather than the topedo ray, and the cover operation means is topedo ray as necessary. Its technical features are that it has a structure that can be combined or separated from the cover coupled to them.

In addition, when the cover is moved to cover the rail cover adjacent to the charter inlet and the charter port inlet in a state where the charter inlet is opened to prevent the molten iron from splashing or flowing down on the rail for moving the cover when the charter is discharged, Another feature of the present invention is the structure in which a scraper that automatically removes the attached now is coupled to the cover.

Topedo ladle car with a sliding cover of the present invention as described above, the pair of front and rear moving trolley on the main rail; A torpedo ladle having both ends rotatably coupled to the front and rear trolleys and having a molten iron inlet formed on an outer surface of an upper end of a longitudinal center portion; A cover means coupled to the upper end surface of the longitudinal center portion of the topedo ladle so as to linearly reciprocate and open and close the molten iron inlet; A cover operating means detachably coupled to the cover means in a state where it is installed on one side of the trolley to reciprocate the cover means; And the like.

The cover means includes: a pair of parallel rails coupled along the front and rear longitudinal directions of the torpedo ladle to the left and right sides of the molten iron inlet of the torpedo ladle; A sliding cover capable of reciprocating along the rail and having a locking end at one end thereof; A pair of rail covers coupled to the front at both ends of the other end of the cover to cover the rails; A scraper coupled to one end of the cover between the two rail covers; And the like.

In addition, the cover operation means, and the girder fixedly installed on one side of the torpedo ladle car; Straight reciprocating means having a connector is coupled to be detachably coupled to the catch of the cover in a state fixed to the girder; And the like.

In this case, as the linear reciprocating means, an apparatus such as an air cylinder unit, a hydraulic cylinder unit, various actuators, or the like may be used. Hereinafter, the cylinder unit will be described.

Looking at how the sliding cover device is configured as described above is as follows.

Prior to the description, the movement of the cover to open the molten iron inlet to avoid confusion in the direction is referred to as "reverse" or "move backward", and the movement of the cover to cover the molten iron inlet is called "forward" or "moving forward". Other movements and directions are also based on this.

After completely discharging the molten iron, the cylinder unit and the retracted cover are separated, the molten iron inlet is open, and the rail cover provided at both ends of the cover covers the rail adjacent to the molten iron inlet. If the extension is coupled to the connector of the outer end of the cover to the engaging hole of the cover and continue to extend the cylinder rod to cover the molten iron inlet as the cover moves along the rail.

In this case, as the cover moves forward, that is, as the cover moves forward, the scraper coupled between the opposite ends of the cover also moves forward with the cover to remove the present around the molten iron inlet.

After the cover coupled to the cylinder unit covers the molten iron inlet as described above, the topedo ladle car moves to the blast furnace and then reduces the cylinder rod to open the molten iron inlet, and receives the molten iron of the blast furnace through the open molten iron inlet. The cylinder rod is extended again to move to the steelmaking plant while covering the molten iron inlet.

In order to discharge the molten iron or to receive the molten iron, the cylinder unit can be opened by reducing the loaded unit to move the cover backward. The outer surface of the torpedo ladle so that the cover can no longer be retracted when the molten iron inlet is completely open. The stopper is provided in the inner rail.

At this time, the cylinder rod is a structure that can be further retracted, that is, further reduced to the rear of the stopped cover, even if the cover is completely stopped by the stopper, and when the cylinder rod is completely reduced, it is stopped by the stopper. The connector of the outer end of the cylinder rod is completely separated from the latch of the cover which cannot be reversed.

That is, the cylinder unit is coupled to the girder installed on the trolley of the torpedo ladle car, and the cover does not contact the trolley, so that the toppedo ladle may The freely rotatable bar allows the torpedo ladle to be tilted freely to release the molten iron.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

FIG. 2 is a partial side view of the embodiment of the present invention Topedo ladle car, and FIG. 3 is a partial plan view of the embodiment of the present invention Topedo ladle car showing the closed state and the open state of the molten iron inlet, respectively. .

As shown, the topedo ladle car equipped with the sliding cover of the present invention,

A pair of front and rear trolleys 200 moving on the main rail R;

A topped ladle 300 having both ends rotatably coupled to the pair of trolleys 200 before and after the molten iron injection hole I provided at an upper end of the longitudinal center portion;

Coupled to the outer surface of the torpedo ladle 300 to be able to reciprocate forward and backward along the longitudinal direction of the torpedo ladle 300 to open and close the molten iron inlet (I) of the torpedo ladle (300) Cover means 400;

A cover operating means 500 which is detachably coupled to the cover means 400 in a fixed installation state on the side bogie 200 to reciprocate the cover means 400; And the like.

The cover means 400 includes a pair of parallel rails 410 coupled to the outer surface of the torpedo ladle 300 at both sides of the molten iron inlet I along the longitudinal direction of the torpedo ladle 300. and; A sliding cover 420 capable of reciprocating along the rail 410 and having a locking hole F at one end thereof; A pair of movable rail covers 430 coupled to opposite ends of the cover 420 and moving together with the cover; A scraper 440 coupled to the other end of the cover 420 located between the two rail covers 430; And the like.

At this time, the cover 420 may be a variety of structures, representative structures are open to the molten iron injection side, that is, the downwardly open type metal casing (420A); A plurality of fixing members 420B attached to the bottom of the metal casing 420A; Refractories 420C filled in the downwardly open inner space of the metal casing 420A; For example, a structure composed of the same may be used. The refractory 420C may be more castable than a refractory brick.

In addition, the cover operating means 500, the girder 510 is fixedly installed on one side of the trolley 200 of the torpedo ladle car; Linear reciprocating means (520) having a connector (C) coupled to be detachably coupled to the catch (F) of the cover (420) in a state of being fixedly coupled to the upper portion of the girder (510); And the like.

And the linear reciprocating means 520, the fixed body 521 is fixed to the girder 510; Reciprocating body 522 is provided with a connector (C) that one side end is reciprocating in a state embedded in the fixing body 522, and the outer end portion is detachably coupled to the catch (F) of the cover 420 ); The fixed body 521 and the reciprocating body 522 include cylinders and cylinder rods.

Topedo ladle car with a sliding cover of the present invention configured as described above, the cover 420 is reciprocated along the rail 410 by a linear reciprocating means 520, such as a cylinder unit, linear reciprocating The maximum linear movement distance that the reciprocating body 522 of the movement means 520 can move is larger than the maximum linear movement distance of the cover 420, and the cover 420 is in a state where the reciprocating body 522 is fully extended. The molten iron injection opening I is completely covered.

However, on the outer surface of the torpedo ladle 300 or on the rail 410, that is, the movement path of the cover 420, the cover 420 is stopped for unnecessary reversal of the cover 420 and separation from the reciprocating body 522. When the stopper S is provided, when the molten iron inlet I is completely open, the cover 420 may not be backed up any more and stop.

At this time, the reciprocating body 522 is in a state capable of continuously reversing, and the reciprocating body 522 further retreats to the rear of the stopped cover 420, thereby separating the reciprocating body 522 from the cover 420.

As the straight reciprocating means 520 installed in the trolley 200 is separated from the cover 420 as described above, the torpedo ladle 300 is freely rotated with respect to the trolley 200 together with the cover 420. Becomes

In addition, the reciprocating body 522, which has been separated from the cover 420, is advanced to the cover 420 side and is coupled to the cover 420 again, and the reciprocating body 522 is further retracted with respect to the stopped cover 420 while the cover 420 In order to be separated from the cover, the cover 420 and the reciprocating member 522 is provided with a fastener (F) and a connector (C), which can be repeatedly separated and connected to each other, the connector (C),

A pair of jersey members C1 which are coupled to both sides of the outer end of the reciprocating body 522 so as to be rotatable and face each other, such that a seesaw or a cradle can rotate at both ends simultaneously in opposite directions. And, it is a flexible jaw (flexible jaw) consisting of an elastic body (C2) interposed between two one end of the two lower member (C1),

The locking hole (F) is fixedly coupled to one end of the cover 420, the lock having a cross-sectional shape of the shape provided with a protrusion (E) facing outward on one side of the outer peripheral surface forming a curved surface, such as a cam As a locking pin, the connector C and the locking hole F may be provided in the reciprocating member 522 and the cover 420 as opposed to the above.

At this time, the two end portions of the flexibleizer are separated from each other by the length of the elastic body C2, and the other two end portions are also spaced apart from each other, and each opposite inner surface of the two other end portions forms a concave curved surface with respect to the counterpart.

Therefore, when the other end of the flexibleizer contacts the locking pin coupled to the cover 420 by the advancement of the reciprocating member 522, the protrusion E of the locking pin is spaced apart from each other between the two other ends of the flexibleizer. Get stuck in

When the flexible force is further advanced to the locking pin side, and the adhesion between the flexibleizer and the locking pin is greater than the elastic force of the elastic body C2, the elastic body C2 is compressed and the two other ends of the flexible body are narrowed at the same time. As the locking pin enters between the two jersey members C1 while the ends are opened, the flexibleizer and the locking pin can be coupled.

As described above, when the cover 420 is pulled and retracted in the state in which the flexible device and the locking pin are coupled, the force applied to the other end of the flexible device toward the outside in the flexible device, that is, the other end of the flexible device is separated. The force to be attempted is smaller than the elastic force of the elastic body C2.

Therefore, when the cover 420 is pulled backward, the other end of the flexible device does not open, so that the cover 420 may be safely reversed.

However, if the cover 420 is no longer retracted by the stopper S and the flexible device is further retracted when the stopper S is completely stopped, the force applied to the other end of the flexible device by the locking pin in the flexible device may be reduced. Gradually increasing with the reverse and eventually greater than the elastic force of the elastic body (C2), the other end of the flexible device is opened, the locking pin is separated to the outside of the flexible device.

As described above, the structure capable of separating or connecting the reciprocating member 522 and the cover 420 as necessary, in addition to the flexible device and the locking pin that can be automatically separated and connected using a reciprocating force, has various forms. Bar, the connecting structure of the reciprocating member 522 and the cover 420 is not limited to be composed only of the flexibleizer and the locking pin.

That is, the reciprocating member 522 may linearly reciprocate the cover 420, but if the reciprocating member 522 can satisfy the idea that the cover 420 should be separated from the cover 420 or be connected to the cover 420 as necessary. ) And the cover 420 is not particularly limited to the detachable connection structure.

In the torpedo ladle car provided with the sliding cover of the present invention, the cover 420 covers the molten iron inlet I provided in the torpedo ladle 300 and the molten iron or the molten iron filled in the torpedo ladle 300 is formed. In order to minimize heat loss inside the discharged torpedo ladle 300, in order to reduce heat loss as much as possible, the bottom surface of the cover 420 is preferably in close contact with the outer surface (or the upper surface) in contact with the molten iron inlet I. .

However, when the bottom of the cover 420 is in close contact with the outer surface in contact with the molten iron inlet (I), the bottom surface of the cover 420 and the outer surface in contact with the molten iron inlet (I) are worn out by repeated reciprocating motion of the cover 420 Not only can it be damaged, but the smooth movement of the cover 420 is also impossible or very difficult.

Therefore, the bottom surface of the cover 420 does not come into contact with the outer surface of the molten iron inlet (I), and at the same time, the molten iron inlet (in order to reduce heat loss through a gap formed between the cover 420 and the outer surface of the molten iron inlet (I)). I) It is also preferable to combine a flexible and resistant to high temperature curtain member 421 to the bottom surface of the cover 420, which can be in close contact with the outer surface, the curtain member 421 is a flexible metal met (metal met) Is suitable.

The metal mat is woven from a metal fiber (metallic fiber) that is very thinly drawn metal, and the metal fiber that can be used at high temperature may be made of an Fe-Cr-Al alloy.

And the lower end of the scraper 440 coupled to one end of the cover 420 may be in close contact with the outer surface in contact with the molten iron inlet (I), but also between the outer surface in contact with the molten iron inlet (I) In view of the wear caused, as shown in FIG. 4, the outer surface of the molten iron inlet I is coupled to be somewhat spaced apart from the bottom of the cover 420, that is, the outer surface rather than the bottom of the cover 420. It is further desirable to remove it closer to now.

In addition, the cover 420 is reciprocated along the rail 410 fixed on the torpedo ladle 300 by the linear reciprocating means 520, and after the molten iron inlet I is completely open The linear reciprocating means 520 is rotated together with the torpedo ladle 300 in a separated state.

Accordingly, as shown in FIG. 5, the cover 420 is completely stopped after the reverse of the cover 420 so that the cover 420 is not separated from the rail 410 when the torpedo ladle 300 rotates. By supporting the upper left and right edges of the cover 420 so that the cover 420 is not separated from the rail 410, the cover release prevention member 450 of the "a" shaped cross section is provided outside the rear of each rail 410 .

In this case, the cover detachment preventing member 450 may cover the two rails together, that is, may have a downwardly open “c” shaped structure to cover the entire reversed cover, such that the cover is detached from the rail of the tilted torpedo ladle. The structure is not limited to a specific one as long as it can be avoided.

Although the ceiling surface of the cover detachment preventing member 450 may be in contact with or close to the upper surface of the cover 420, the cover detachment preventing member 450 and the cover 420 are sufficiently dropped from the upper surface of the cover 420. The support roller 451 in close contact with the upper surface of the cover 420 between the support) of the cover 420 rotated together with the torpedo ladle 300 and the reciprocating movement of the cover 420 returned to the normal position. In more preferred, the support roller 451 may be coupled to any one side of the cover 420 and the cover removal prevention member 450, the support roller 451 is provided in the cover 420 support roller ( 451 is in close contact with the ceiling surface of the cover detachment prevention member 450.

In addition, in order to more stably support the cover 420 when the torpedo ladle 300 rotates, as shown in (b) of FIG. 3, a fixing pin P is provided on the front surface of the stopper S. It is more preferable to have a coupling hole (H) in which the fixing pin (P) is detachably inserted into one end surface of the cover (420) in close contact with the front surface of the stopper (S).

At this time, the fixing pin (P) is good to be elastically inserted into the coupling hole (H), the stopper (S) may be provided in the front of the cover 420.

When the cover 420 moves forward to cover the molten iron inlet I when the cover 420 is completely retracted, the torpedo ladle 300 is rotated back to its original position, that is, the cover 420 is normally on a horizontal plane. Since the cover 420 cannot be detached from the rail 410 because it is movable, the front part of the rail 410 needs to include the cover removal preventing member 450 and the support roller 451. There is no.

In addition, a plurality of cover rollers 422 reciprocally moved along the rails 410 are provided at both ends in the width direction of the cover 420, and the cover rollers 422 and the rails 410 are fixed rails 410. When the cover roller 422 is flowed in the horizontal direction perpendicular to the longitudinal direction of the rail 410, the cover roller 422 should have a coupling structure that does not deviate to both sides of the width direction of the rail 410. .

And the power generating device such as hydraulic pressure, pneumatic, etc. to be supplied to the cover operating means 500 in order to reciprocate the cover means 400 coupled to the torpedo ladle 300 in the state installed in the bogie 200 200 may be provided separately from the torpedo ladle car, such as a steel mill, blast furnace, etc., to which the cover means 400 must be moved after stopping the torpedo ladle car.
