Definitions

  • the invention relates to a method and a device for loading and unloading a ladle turret in a continuous caster according to the features of the preambles of claims 1 and 2.
  • the ladles are set down from above by a ladle crane onto the support arms of a rotating tower and the ladle support arm is then pivoted together with the ladle from the ladle loading position to the pouring position.
  • the rotating pan can be used to move the empty pan from the pouring position to the loading position and the filled pan from the loading to the pouring position.
  • a ladle turret in a continuous casting plant which consists of a central column and two ladle support arms.
  • the pan support arms are provided with support surfaces for pans and can be raised and lowered by means of lifting devices above an upper edge of an intermediate vessel in the casting position.
  • the lifting and lowering ability is intended for the insertion of a pouring tube into the intermediate vessel and for an intermediate vessel change.
  • This turret is loaded and unloaded using the classic method.
  • the ladle is lifted from a floor conveyor by means of a ladle crane and to a height above an upper edge of one in the pouring position placed intermediate vessel brought.
  • the ladle is then set down from the ladle crane onto the support arms, which are also at a height above the intermediate vessel, or lifted off when unloading.
  • a disadvantage of such ladle turrets is that large ladle cranes are required to load the turret, which can raise the ladles to a height sufficient to place the ladle on the ladle support arms.
  • Such ladle cranes are expensive and require correspondingly high halls.
  • the object of the invention is to further improve the ladle turret and to eliminate the disadvantages mentioned.
  • a revolving tower is to be created that can be installed in much lower ladle transport and casting halls.
  • the lifting device should also not be exposed to heat radiation from the liquid steel in the pan.
  • the pan should continue during the pivoting movement and not be suspended from a hoist winch during casting operation. This is intended to eliminate rocking movements of the pan during and after the pivoting movement about the vertical axis of the turret, in particular in the event of a rapid pivoting movement in emergency situations.
  • the ladle turret according to the invention should be simple and inexpensive and, together with the ladle transport and casting hall, which is reduced in height, should enable substantial savings in investment costs.
  • the method according to the invention it is possible for the first time in practice to limit the clearance height of the ladle transport and casting hall in the rotating tower area by several meters, practically to the height of the top of the ladle.
  • the room height in the area outside the ladle turret could, if no other requirements so require, be built much lower.
  • a corresponding ladle or pouring crane can be omitted in both of the halls mentioned.
  • the lifting devices arranged on the revolving tower are not exposed to any heat radiation from the liquid steel or the empty inside of the pan, so that additional measures to eliminate this harmful radiation are unnecessary.
  • the firm support of the pan on the pan support arm eliminates any risk of rocking movements of the pan during and after the pivoting movement of the turret.
  • the simple concept of the turret is based on a single lifting device for loading and for lifting and lowering in the pouring position for extending and retracting the pouring jet protection between the ladle and the intermediate vessel.
  • the ladle turret according to the invention is characterized by the sum of the features of claim 2.
  • the height of a rotation plane for the pan rotating tower can be determined.
  • the center column can also be built low.
  • the invention additionally provides that the center column is provided with vertical guides for vertical movement of the socket support arms and that a lifting device, preferably made of hydraulic piston-cylinder units for the movement of the socket support arms, is connected to the pivotable center column are.
  • a lifting device preferably made of hydraulic piston-cylinder units for the movement of the socket support arms
  • pan support arm is connected to the central column via a horizontal axis and can be pivoted about this axis from the self-loading position into the casting position.
  • a low susceptibility to wear and a vibration-free lifting movement of the pan make this variant appear advantageous.
  • Such a construction is also favorable in terms of investment.
  • Both pan support arms can be rigidly connected to one another and pivoted by means of a single lifting device. Such a simple device should be considered for small pan sizes.
  • the beam-like double support arm essentially reduces the lifting weight to the weight of the pan contents.
  • Independently articulated support arms can be designed with a single or a double control lever. Additional advantages can be achieved if the double control lever is articulated on one side to the turret column and on the other side to a pan chair in the sense of a parallelogram. The ladle chair always remains in the desired horizontal position during the lifting movement by the double link.
  • the piston-cylinder units for moving the socket support arms can be articulated on the center column as well as on the support arm at different points and in different positions.
  • the piston-cylinder unit should pivot as evenly as possible about a vertical axis. Wear and maintenance costs can be reduced, for example, compared to oblique or horizontal piston cylinder units. The space requirement is also minimal.
  • the device also optimizes a ladle stroke / piston stroke ratio of 2: 1.
  • a stationary support device can be arranged in the pouring position, on which the ladle support arm is supported in the pouring position becomes.
  • This stationary support device can be connected to the structure of the casting platform.
  • pan support arm 5 can be moved by a lifting device 18.
  • pan support surfaces 20 on the support arm 5 can be lowered to a level 21 below the support surfaces 22 of the pan 2.
  • the ladle support arm 5 can lift the ladle 2 by means of the lifting device 18 in the form of a piston-cylinder unit, from the ladle wagon 1 traveling at steelworks floor height 25 or generally floor conveyors themselves.
  • the dotted line 2 shows the pan 2 again in the raised position.
  • a center column 30, which can be pivoted in a plane of rotation 27, can raise the pan support arm 5 in the casting position 31 above an intermediate vessel 32 by rotation by 180 degrees.
  • the empty pan 2 'on the support arm 5' is brought to the loading side.
  • the empty pan 2 ' can be lowered onto the pan carriage 1 and transported away at the steelworks floor height 25.
  • the plane of rotation 27 is attached on the foot side of the center column 30. Above the plane of rotation 27, a platform 15 is rigidly connected to the rotatable center column 30. It is based on a bearing ring 4, for example a roller bearing. With 7 the foundation of the turret 3 is shown.
  • the piston rods 17 are articulated with bolts 16 on the pivotable platform.
  • vertical guides 12 are attached divided into sections. Rollers 10, 11 of the pan support arms 5, 5 'are guided along these guides 12.
  • the dash-dot raised position of the pan 2 on the left side of the center column is a measure 32 higher than the position of the pan 2 'on the right side. This additional height serves to move a pouring tube 34, 34 'into the intermediate vessel 33 or mold 36, if such Pipes can be used as pouring jet protection.
  • a stationary support device is shown at 35, on which the pan support arm 5 'is lowered and supported in its height that is most favorable for casting.
  • the piston-cylinder unit 18 'must therefore first lift the support arm 5'.
  • pan support arms 42, 42 ′ are articulated on a central column 41 via a horizontal axis 40.
  • Piston cylinder units 43, 43 ' can pivot the support arms 42 from a self-loading position 45 into a casting position 46.
  • a beam-like support arm which can be pivoted by means of a single lifting device, can be built.
  • an intermediate vessel is shown, which is arranged above a continuous casting plant 48.
  • 49 shows a support device for the support arms 42 in the casting position.
  • the axes 60, 60 'of the lifting movement of the pistons of the lifting cylinders 43, 43' run essentially vertically, the articulation axes 62 pivoting about an arc 63 around the axis 40.
  • the arrangement of the lifting cylinders 43 can be selected such that the lateral cylinder pivoting 68 comes to rest on both sides of a vertical axis 69 during the lifting movement.
  • the support arms 51, 51 ' are designed as double links.
  • a pan support chair 52, 52 ' is arranged at each end of the double link. At the opposite ends they are on a central column 54 of a rotating tower in the Articulated in the sense of a parallelogram.
  • piston-cylinder units 55, 55' are articulated on a support plate 56 which is connected to the rotatable center column 54.
  • the piston rods 57 are connected to the lower link 58, 58 '.
  • the center column 54 with the support plate 56 is rotatably mounted on a ball or roller bearing 64 on a foundation plate 65.
  • Known drives can be used for the rotary movement of the turret.
  • the required room height in the area of the turret is shown at 70.
  • the height of the hall can be chosen to be significantly lower.
  • the pan in the pouring position is always arranged above the pan in the self-loading position in the pan turrets according to the invention, regardless of the examples in FIGS. 1-4.
  • the elevation 21 below the wings 22 of the pan is provided below the upper edge of the intermediate vessel 33.
  • the height difference between the height 21 and the upper edge of the intermediate vessel is at least 1.5 m. This distance can also be 2 m or 3 - 5 m and more.
