Definitions
- the invention relates to a device for machining the edges of cast strands by machining, each comprising a machining tool that can be brought into contact with a longitudinal edge of the cast strand, and at least one guide for perpendicular positioning of the machining tools on the longitudinal edges.
- the invention also relates to a system made up of a cast strand, preferably a continuously cast cast strand, and such a device.
- the invention also relates to a method for machining the edges of cast strands by means of a device provided for this purpose.
- Previous edge bevelers for processing the longitudinal edges of cast hot billets process the longitudinal edges of the cast strand at a cutting speed that cannot be influenced but is dependent on the casting speed of the cast strand for chamfering.
- the setting of the chisels relative to the longitudinal edges usually takes place via two linearly guided, pneumatically pretensioned carriages. Such a prior art device is shown in Figure 1 below.
- a disadvantage of these devices according to the prior art is that the cutting speed of the chisel is limited and predetermined by the casting speed of the cast strand. This results in flow chips that lead to quality problems. These flow chips may end up in the downstream rolling mill and lead to quality problems in the finished product. Furthermore, there are often problems with the linear and pneumatically preloaded guides, as follows. The guides have the task of compensating for the transverse movements of the billet and thus keeping the depth of cut constant. The solution according to the prior art is defective due to soiling and also so-called drawer effects.
- the previous edge planer had no way of influencing the cutting speed of the continuously cast strand and is therefore dependent on its casting speed.
- the casting speed is not sufficient to achieve the required cutting speed, which is highly necessary for a chip.
- the resulting flow chips cannot be easily discharged into a collection container and prevent trouble-free operation.
- the flow chips make it necessary to intervene manually in the process from time to time.
- the setting of the cutting tools preferably the four chisels, takes place via two linearly guided, pneumatically pretensioned slides. There is preferably one carriage on the drive side and one on the operator side of the cast strand, each with two bits to bevel all four edges.
- the cast strand can have a lateral deflection, which is to be compensated for by the linear adjustment.
- the foundry environment e.g. heat, dirt and water
- the lateral movement of the cast strand can therefore no longer be adequately compensated and leads to different depths of cut, which are reflected in the end product.
- the device for machining the edges of cast strands by machining has a machining tool that can be brought into contact with a longitudinal edge of the cast strand, and at least one guide for positioning the machining tools vertically on the longitudinal edges of the cast strand.
- the invention is characterized in that means are provided for moving the cutting tools parallel to the longitudinal edges of the cast strands in order to vary the relative speed between the longitudinal edges and the cutting tools.
- the cutting tools are hereby set in motion relative to the cast strand speed in order to ensure that the machining of the longitudinal edges of the cast strand is not exclusively dependent on the casting speed of the cast strand. In this way it can be ensured that flow chips can be reliably avoided and the machining process can be carried out without disruption and in particular without damaging the finished product.
- the cast strand is preferably a slab or a sheet, in particular a continuously cast cast strand.
- the cutting tool is a chisel, preferably an edge plane. It is preferred if the vertical guide for the cutting tools in relation to the longitudinal edges of the cast strand comprises a carriage, preferably with means for pneumatically or hydrostatically applying force to the cutting tools.
- the carriage is connected to rollers which can be brought into contact with at least one surface, preferably two opposite surfaces, of the cast strand in order to enable lateral tracking of the carriage in relation to changes in the position of the cast strand within the device. It is also particularly preferred if the carriage is mounted so that it can slide horizontally on at least one vertically arranged column, preferably two vertically arranged columns. The lateral deflection of the cast strand is reliably compensated by this arrangement of the carriage within the device.
- the setting is preferably made using a pneumatic cylinder with the appropriate parameter setting. Depth of cut adjustments can preferably be made relative to the carriage.
- the roller guide ensures that a constant depth of cut is maintained.
- an oscillating movement of the tool relative to the longitudinal edge can be brought about by the means for parallel movement.
- the means for parallel movement comprises an eccentric drive, preferably an eccentric motor, via which an oscillating movement of the cutting tool, preferably each cutting tool, relative to the longitudinal edge of the cast strand can be effected.
- the motorized eccentric drive causes the rotational movement of the eccentric to translate into a translational movement of the cutting tool in relation to the longitudinal edge of the cast strand.
- the speed and / or the eccentricity of the eccentric drive are variably adjustable.
- Such an eccentric drive causes the relative speed of the cutting tool to change regularly and periodically in relation to the longitudinal edge of the cast strand to be machined, thereby ensuring reliable chip breakage.
- the oscillation and the associated change in direction of the cutting tools result in targeted chip breakage and thus a defined chip parameter.
- the chips can be discharged into the chip collection tray without any problems, minimizing the risk of chips being rolled into the downstream rolling mill.
- the cutting depth is preferably optimized by means of an adapted guide, which results in a higher quality of the cast strand and ultimately a higher quality of the product that is ultimately to be produced. Additional manual intervention by the operating personnel is avoided.
- the cutting speed is readjusted via feedback of the casting speed to a control module, as a result of which optimal machining conditions can be ensured at all times.
- the wear of the tools in particular the chisels, can be evaluated via parameters of the motorized drive, preferably the eccentric drive. It is particularly preferred if exceeding of parameter limit values is evaluated by software provided for this purpose, with this software preferably signaling that the limit values have been exceeded after the evaluation and thus an unplanned downtime of the machine can be avoided altogether. Condition monitoring performed in this way ensures greater availability of the device according to the invention. 5. Detailed description of the figures:
- Figure 1 shows a sectional side view of an edge beveler for a continuously cast strand according to the prior art
- Figure 2 shows a sectional plan view of a device according to the invention
- FIG. 3 shows a side view of a device according to the invention.
- FIG. 1 shows a sectional side view through a device 1 for machining the edges of cast strands 2 according to the prior art.
- the cast strand 2 is guided through the device 1 from left to right at casting speed and in the process passes four edge planes (not shown), which are delivered to the longitudinal edges of the cast strand 2 by means of linear adjustments 4 .
- a means for changing the relative speed between the edge planers (not shown) and the longitudinal edges of the cast strand 2 is not provided.
- Figure 2 shows a view from above of a device 1 in an embodiment according to the invention.
- a cast strand (not shown) runs through the device 1 from the bottom left to the top right in the figure and passes four chisels 3, which on the one hand are fed perpendicularly onto the strand (not shown) by means of a pneumatic adjustment and on the other hand an oscillating movement run in the orientation and amplitude of the movement arrows 11 shown. This results in a regular change in the relative speed between the chisels 3 and the longitudinal edges of the cast strand (not shown).
- the cast strand (not shown) as it enters the apparatus 1 passes rollers 10 which come into contact with the cast strand (not shown) and can thus follow a lateral movement of the cast strand (not shown).
- rollers 10 are in turn connected to the carriage 8 in such a way that a movement of each roller 10 towards or away from the cast strand (not shown) is transmitted directly to the carriage 8 .
- This carriage 8 in turn is pivoted about a fixed point on the strand outlet side of the carriage 8, which ensures that the carriage 8 and the chisels 3 guided therein are permanently and evenly positioned on the cast strand (not shown).
- a vertical column guide 6 allows the horizontal sliding of the carriage 8 in the plane in which the cast strand (not shown) passes through the device 1.
- FIG. 3 shows a side view of a preferred embodiment of a device 1 according to the invention, in which the eccentric drive 7 is shown, via which a periodically acting deflection of the carriage 8 relative to the direction of movement of the (not shown) cast strand through the device 1 is effected.
- the eccentric drive 7 outputs a vibration dependent on its rotational speed and a vibration amplitude dependent on its eccentricity to the carriage 8, which executes an oscillating movement to the left and right in the figure.
- the carriage 8 in turn is mounted between two leaf springs 9, by means of which the vibratory movement applied by the eccentric drive 7 to the carriage 8 is damped and cushioned in the desired manner.
