Definitions
- the invention relates to a strip casting machine according to the features of the preamble of claim 1.
- the object of the invention is to create a strip casting machine which overcomes the disadvantages mentioned in the prior art and which in particular improves the exchange of the narrow sides and thereby shortens the set-up time between two castings.
- the narrow sides should be able to be positioned more precisely and heated up to the start of casting. Furthermore, the narrow sides should remain connected to all supply and detector lines of the monitoring system for such narrow sides during the alternating movement.
- a key sub-goal is improved accessibility to the casting rolls, in particular for changing the casting rolls and easier protection against oxygen access to the part of the casting machine on the casting and strip exit side (inerting). The problems that arise with a roll diameter larger than 800 mm and correspondingly large narrow side plates are also to be solved.
- the movement of the narrow side plate by means of the carrier element can take place in a straight line, vertically or obliquely, as well as curved downwards.
- the carrier element is advantageously designed as a support arm.
- the support arm can pivot about an axis or move along a curve. Below the machine, the narrow side on the support arm can be replaced with a new narrow side and moved back to the starting position in the same way.
- the designation position includes every plate position between the casting position and an exchange position.
- the support arm in a first movement step, can move the narrow side substantially horizontally and in the longitudinal axis of the casting pipes away from the machine stand.
- the narrow side can be shifted on a horizontal shift track, which is approximately at a height below the pouring channel.
- the support arm with the Narrow side can be adjusted essentially parallel to the end faces of the casting pipes.
- the sliding track can feed the narrow side to a narrow side changing station, which is spatially separated from the casting platform by a wall.
- a narrow side changing station allows the following work, such as cleaning, maintenance, changing, adjustment, preheating of the narrow side, to be carried out in an orderly and clean manner, with the exclusion of an accident risk.
- the narrow side part can be displaceable downwards between the bearing journals or bearing points of the casting pipes.
- the narrow side can be slid downwards with or without adjusting means between the end faces of the roller bales and the machine stand. If necessary, the pouring pipes are opened at a distance.
- the casting machine can be made particularly narrow if the setting and positioning device is arranged on the machine stand and can be coupled and uncoupled with the narrow side part in the setting position.
- the movement between the adjusting and casting position can be carried out using a pressure medium and piston-cylinder units or electromechanically.
- the support arm When the narrow side part is brought into the setting or pouring position, the support arm can be separated from the narrow side part, if desired. According to an advantageous embodiment, the support arm can remain connected to the narrow side part in the casting position. If the narrow side part moves downwards together with the adjusting device, ie the adjusting device is also mobile, it needs a centering and support surface in the adjusting position in relation to the machine stand in order to introduce the adjusting force into the machine stand.
- the narrow side changing device advantageously consists of a support arm with a vertical and a horizontal support, the horizontal support generally being connected to a lifting device.
- the narrow sides can be provided with electromagnetic coils to generate an electromagnetic field for gap sealing.
- An additional shortening of the changeover time for the narrow side parts can be achieved if two narrow side change devices are arranged on both sides of the casting tubes, the worn narrow side being able to be guided away from one change device and the new narrow side being able to be fed in from the other change device.
- FIG. 1 shows a view of a strip casting machine shown schematically
- Figure 2 is a vertical section through an example of a partially shown
- FIG. 3 shows a vertical section through a further example of a strip casting machine, partially shown
- FIG. 4 shows a side view, partly in section through an upper part of a strip casting machine
- Figure 6 is a view of a narrow side part
- FIG. 7 shows a horizontal section through a further example of a narrow side part.
- a strip casting machine is shown schematically, which consists of two essentially parallel casting pipes 2, 3, narrow side parts 4 and a machine stand 5.
- the two casting tubes 2, 3 are supported by roller supports 6, 7 from the machine stand 5.
- Arrows 12, 15 and 13, 14 schematically indicate two different drainage paths for changing the narrow side 4.
- a dash-dotted line shows a support element 9 which is drawn as a support arm in the present exemplary embodiment.
- each version can be used, for example, a crank mechanism, a joint mechanism, a slide guide or the like.
- the support arm can move the narrow side 4 by one Move axis 11 down along a circular line (arrow 12). If desired, the circular movement (arrow 12) can be followed by a horizontal movement (arrow 15).
- Arrow 13 shows how, in the sense of an alternative to the circular line, the narrow side 4 can be displaced vertically downwards by a support arm (not shown in this figure).
- An arrow 14 indicates a horizontal displacement of the narrow side 4 away from the machine stand 5 following the vertical movement.
- the arrows 14 and 15 show a direction which runs transversely to the longitudinal axes 16, 17 of the pouring tubes 2, 3.
- An arrow 14 ' indicates the feeding of a new narrow side by means of a second narrow side changing device.
- 22 is a partially shown casting roll and 24 a narrow side in a position.
- the narrow side 24 is arranged on a narrow side changing device in the form of a support arm 29.
- a gap 26 is present between a sealing surface 25 on the end face of the roller 22 and the narrow side 24 in the working position. The gap 26 is closed by moving the narrow side 24 from the setting position into the casting position.
- An adjustment device 27 with centering device 28 and lifting device 30 is provided for the employment.
- the adjusting device 27 is arranged on a machine stand 21 and the lifting device in the form of piston-cylinder units 30 can be coupled and uncoupled to the narrow side 24 in the setting position.
- the piston-cylinder units 30 of the adjusting device 27 can press the narrow side 24 from the adjusting position in a controlled manner onto the end face (sealing surface 25) of the casting roller 22, ie move it into the casting position and back again into the adjusting position.
- both the narrow side 24 and the adjusting device 27 are arranged on the support arm 29.
- the entire unit, consisting of narrow side 24, adjusting device 27 and support arm 29, can move down together.
- the narrow side 24 is in the position of FIG. 3. It can be brought into the casting position by the lifting devices 30, that is to say it can be pressed against the casting roller 22 in a gap-sealing manner.
- the unit can be centered on the machine stand 21 and during the adjustment the machine stand 21 or a supporting part 33 can absorb the positioning force of the lifting devices 30.
- the support arm 29 can be designed to be displaceable or adjustable in the axial direction of the casting tubes 22.
- FIGS. 2 and 3 show how the narrow side part 24 can be displaced downwards and upwards again according to arrow 20, once with and once without adjusting device 27, between the end faces of the roller balls of the casting tubes 22 and the machine stand 21.
- FIGS. 4 and 5 show an example of a strip casting machine, each with two narrow side changing devices 40, 40 ', 41, 41', which are arranged on both sides of the casting machine.
- the narrow sides are designated 42, 42 '.
- a support arm 43 consists of a vertical support and a horizontal support 44, which are assembled at an angle.
- the horizontal support 44 is connected at one end to a lifting device 45, which can move the support arm 43 and the narrow side 42 vertically downward from the position of engagement.
- a horizontal displacement track 46 can move the horizontal support 44 with the support arm 43 together with the lifting device 45 according to arrow 47. So that all sales supply lines for the narrow side 42 can be tracked smoothly during the vertical and horizontal displacement, the sliding track 46 is provided with a drag chain 48 for supply lines.
- a narrow side is shown on the left side with a dash-dot line at 42 "during the horizontal displacement on the sliding track 46.
- the narrow side 42" is shifted to a height 49 below the journals of the casting tubes 39.
- the narrow side can be removed by the horizontal displacement an airtightly sealed inerting space 50, which is filled with an inert gas, can be brought through a closable opening 51 into a lock space 52, which is also filled with inert gas.
- the narrow side change device 40 'on the left side of the casting channels 39 can lead the worn narrow side 42 away from the casting machine and the new narrow side can be fed from the narrow side change device 40 on the right side of the casting rolls 39.
- the narrow side change devices 41 'and 41 can be used to change the narrow side 42' simultaneously with the narrow side 42.
- the lock chambers 52, 52 ' can be moved away from the inerting space 50, as shown by arrow 54 on the right-hand side, and the narrow sides 42 can be in a direction transverse to the sliding path 46 arranged transport device 55 handed over and brought to a maintenance room (not shown) for narrow side parts.
- the narrow side changing device 40, 41 can also move out of the lock space 52, 52' by horizontal displacement and, if desired, the narrow side can be fed directly to an maintenance space.
- FIG. 6 schematically shows a narrow side 60 with electromagnetic coils 61, 61 '. These coils 61, 61 'generate an electromagnetic field, in order to additionally seal the sealing surface between the narrow side 60 in the pouring position and the end faces of the bales of the two pouring tubes against leakage of pouring metal. Electromagnetic fields for gap seals are known in the prior art and need no longer be explained.
- FIG. 7 schematically shows a section through a narrow side 70 with an electrical heater 71 inside the narrow side 70.
- This heater 71 enables the narrow side to be heated when moving the narrow side 70 between a narrow side maintenance space or a narrow side preheating position and the casting position. This measure helps to shorten the downtime between two castings.
- the heater does not have to be arranged in the narrow side 70 itself, it can also be attached to the narrow side 70 in the form of an additional device 72 (dash-dotted lines), for example.
