Definitions
- the invention relates to a method for changing the format thickness of the cast strand a continuous caster in continuous casting operation, with the strand below a mold on both sides with opposite roller carriers is in operative connection, the segments in a sequence of roles are divided and each segment individually adjustable at an angle to the cast strand and, in a starting position, the whole to be changed Strand guidance is set to a production format thickness.
- the thickness is the strand shell formed essentially depends on the casting speed.
- the Rolling force can be adapted to the current strand shell thicknesses. If too little Casting speed, the available rolling force is no longer sufficient, so that it comes to exceed the target thickness of the cast strand produced. If it is too high Casting speed can only be achieved by welding the strand shells Falling below the target thickness of the cast strand produced can be achieved.
- transition piece with a smaller thickness, which is not rolled can be separated from the slab and as scrap is chopped. Due to the reduced thickness, the transition piece is also relatively cold, so that the scissors are heavily loaded when chopping.
- the patent DE 43 38 815.2 describes a method and an apparatus for operating a continuous caster, especially when casting the continuous caster for the production of thin slabs for hot strip rolling, with at least one pair of reducing rollers arranged downstream of the continuous casting mold, which, or which join adjustable strand guide elements.
- the pair of reducing rollers after a given length of the cast strand set to a smaller gap width causing the sump to be squeezed.
- the cast strand becomes a sprue format with a thickness below the desired final format deformed thickness.
- the strand guide elements or the reducing roller pair are then to the thickness of the final format hired as soon as the less thick sprue format completely in its setting range has arrived.
- the pair of reducing rollers is pressure-controlled and is after the Positioning the strand guide positioned on the final format.
- EP 0 743 116 A1 discloses a vertical casting line for cast strands comprising a mold and then an assembly with at the outlet of the mold Casters, also a variety of management units, assigned role segments as well as a driver arrangement in conjunction with a horizontal Casting line segment.
- the leadership units include at least the entire vertical segment of the casting line, with at least part of the roles of the guide units interact with actuators that are from a process data unit be mastered, at least to a controllable soft reduction in the second part of the vertical segment.
- the published patent application DE 196 39 297 A1 describes a method and a device for high-speed continuous casting plants with a reduction in strand thickness during solidification.
- the strand cross section is used during the solidification linear over a minimum length of the strand guide immediately below the mold is reduced in thickness.
- the "soft reduction" up to a maximum of immediately before final solidification or the top of the sump, can a critical deformation of the strand taking into account the Switch off the casting speed as well as the steel grade.
- Document EP 0 450 391 B1 discloses a device for supporting a Metal casting strand, especially for soft reduction (also called “soft reduction") in a pre-cast caster, below to the continuous casting mold both sides of the casting strand opposite mirror carriers are provided, the rollers of which are operatively connected to the casting strand.
- Everyone Roller carrier is arranged in a fixed frame and in several, roller-bearing Split segments that are related to adjustment devices. The segments are articulated to each other so that each segment for can be set at any angle to the casting line, and that the upper adjustment device is used for general adjustment of the roller carrier. It can be a mechanical, hydraulic or mechanical-hydraulic one Act adjusting device.
- the object of the invention is based on a method and a method of carrying it out which is suitable for changing the format thickness of the casting of a continuous caster in continuous Casting operation to specify at which the casting speed for the transition process to change the format thickness does not have to be reduced, i.e. it should constant production and casting conditions are maintained.
- a transition length of the strand during the change in format thickness is to avoid Production losses can be reduced comparatively. In all transitional situations
- the change in format thickness is intended to reduce breakthrough risks optimal strand support can be guaranteed. Cold thicknesses, which the Stressing the chopper high mechanically should be avoided.
- the measures according to the invention for changing the format thickness of the cast Stranges is achieved that the casting speed e.g. in the reduction from the thicker format to the thinner format or from the thinner format to the thicker format does not need to be changed and the casting conditions can remain largely constant. Loss of crop, loss of production mean are avoided. There are cold thicknesses at the beginning of the slab or slab end avoided, the unnecessary mechanical load on the Chopper shears mean. The changes in thickness can be infinitely varied Adjustment range carried out depending on the respective production program and thus result in a high flexibility of the system. Of special The advantage is the adaptation of the tapping thickness in the rolling mill to the required one Final rolling thickness.
- the cast strand on The beginning of the strand is set to a constant thickness over a length of about 1 to 4 m is also proposed that the cast strand at the end of the strand a length of about 0.5 m to 2 m is set to a constant thickness.
- the transition length of the Thickness change in the longitudinal direction of a defined wedge shape with a defined one Slab profile follows; i.e. between the beginning and end of the strand a constant thickness is arranged in a wedge shape, whereby the resulting slab of slab if an acceptable slab profile is observed can be rolled out.
- the transition length depends on the amount of the thickness reduction and the adjustment parameters. Using this procedure is great even at large Slab thickness changes of e.g. 25 mm the thickness gradient is sufficient small, so that there are no thickness tolerance problems when rolling.
- segment 1 on the outlet side and that Segment 2 closed or opened on the inlet side From a certain length, segment 1 on the outlet side and that Segment 2 closed or opened on the inlet side. Delayed or delayed then segment 2 at the length of segment 2 Outlet side and segment 3 closed or opened on the inlet side. Then, again delayed by the length of segment 3, the Segment 3 closed on the outlet side and segment 4 on the inlet side or moved up. Finally, the outlet side of segment 4 is delayed away again by the length of segment 4 - closed or opened.
- Advantageous all segments are moved until they are on the desired one Final thickness.
- the adjustment steps are simultaneous or predominant made at the same time.
- the adjustment speed is comparatively slow and is, for example, less than 2.5 mm / min. This way of driving becomes a Slab profile creates that no unacceptable thickness differences for rolling Has center / edge.
- a further embodiment of the method according to the invention provides that The segments are closed at a constant speed using dynamic position control is carried out, but a force threshold to be determined is not is exceeded.
- Figure 1 shows the functional flow of the method for a format thickness reduction a cast strand 9 of a continuous caster in continuous casting operation.
- the strand 9 is below a mold 10 on both sides with a mirror image opposite roller carriers 8, 8 'in operative connection, which in a Sequence of roller-bearing, coupled to one another by means of articulated connections 5 to 7 Segments 1 to 4 are divided.
- Each segment 1 to 4 is in itself an angle to the cast strand 9 adjustable.
- the whole is in a starting position strand guide to be changed to a uniform production format thickness set as this corresponds to the starting position shown.
- the format thickness change is in a regulated sequence of adjustment steps of segments 1 carried out to 4.
- the format thickness is reduced by closing sequentially in the casting direction of the successive segments 1 to 4, as shown in the figures Phases 1 to 4 can be seen.
- the articulated connection begins with segment 1 on the outlet side 5 closed with segment 2 inlet side setpoint-controlled.
- segment position for the target format in a second adjustment phase segment 2 outlet side with segment 3 inlet side closed, and in sequential order of similar steps the segments 3 and 4 are adjusted according to phase 3 shown or 4.
- the force means 11 engage at the articulation 5 Direction of a narrowing of the cast strand 9, followed in phase 2 by the intervention the adjusting device 12 in the direction of a narrowing of the strand cross section and continue sequentially in phase 3 and phase 4 of the adjustment devices 13 and 14 up to the overall reduced format thickness, according to Final state in phase 4.
- segment 1 At the start of the thickness reduction after phase 1, segment 1 will be - as I said Outlet side and segment 2 inlet side are setpoint-controlled at constant speed closed by means of dynamic position control.
- Force threshold is a to be determined Force threshold not exceeded.
- the approach speed will taking into account the permissible elongation limit values and the current Casting speed in connection with the current format setting or after Calculation of the resulting volume flow of the line is calculated.
- Effective force monitoring predictable, for example, using the current one Cylinder pressures of a hydraulic adjustment device monitors the adjustment process. If the force exceeds a calculated limit, from Position control switched to force control. After reaching the target position is switched back to position control accordingly.
- the sequence described ensures that the material thickness is reduced the continuous decreasing wedge shape, the roller apron an adequate Supporting the strand 9 and that the outlet side corresponding to the Material thickness is tracked.
- the existing swamp in segment 1, 2 and possibly 3 is not through interrupted the process.
- the strand support can be switched over from position given on force control in all phases.
- the entire strand guide is in Casting operation set to a production thickness X.
- the casting speed is constant, the bottom of the swamp is in segment 3, the increase in thickness is with phase 1 started.
- segment 2 outlet side is opened (phase 2).
- the adjustment speed is calculated from the current casting speed, the segment length and the required adjustment path as for the reduction in format thickness.
- Effective force monitoring calculated using the current cylinder pressures hydraulic adjustment devices, controls the adjustment process.
- position control switched to force control. After reaching the target position will be accordingly switched back to position control.
- segment 3 becomes the inlet side at the same time with the same adjustment speed as segment 2 outlet side opened, according to phase 2.
- Die Monitoring function is the same as for segment 2 outlet side.
- segment 3 becomes Outlet side and segment 4 inlet side opened (phase 3).
- the calculation the casting speed and the monitoring are carried out as described above.
- segment 4 becomes Run-out side opened (phase 4). Monitoring is calculated as previously described.
- the adjustment device is advantageously equipped with means for or force control.
