Description
The present invention relates to that a kind of it has with motor-driven central shaft and multipair bar accommodation section for removing when bluster is cut the burr removal device of the burr producing at slab place, described bar accommodation section is fixed on described central shaft respectively at each interval.
When carrying out gas cutting with oxygen, in beginning and the end of two bottom gas cutting edges, the slab that cuts from continuous casting billet at each, all can due to flow out and cooling cutting slag more or less produce by crisp iron oxide and hard until the large burr that the mixture of flexible steel forms.These burrs partly hang down very long or form projection in the edge of workpiece bottom from edge.Continuing to add man-hour and during at transportation slab, the existence of these burrs can cause very burden.
Generally can be for slab is provided with two cutting torches, so that burning can be carried out quickly.At this, the burr removal device with hammer extends on the whole width of slab with Breadth Maximum.But because slab has different in width, so the hammer of burr removal device is removed in region than side zones, on right side and left side, in abutting connection with the location of zone line, is being loaded more consumingly and more continually respectively at middle burr.Therefore, the hammer of burr removal device in zone line than suffering higher wearing and tearing in the side zones of each slab.Like this, at width of plate slab hour, the exterior lateral area of burr removal device must be few than use in zone line.In the region intersecting at two burners, the wearing and tearing in slab zone line still will improve, because produce there harder cutting burr.
Therefore there is serial of methods to come gas cutting after, from slab, to remove deburring as early as possible, more precisely by fusing or calcination, carry out scafing, manually destroy or chisel out or destroy, press, cut and remove deburring with the machine that is equipped with hammer class, chisel class or shear blade class instrument with hand-held oxygen lance or oxygen cutter.
It is a kind of that for removing roller-way at continuous casting installation for casting, not stop the effective burr removal device of the cutting burr at the slab place of operation be continuously the rotary burr removal device with rotor quick rotation, that be equipped with hammer.But broken because the burr on slab often and unevenly comes with great power and speed by many little hammers, so produce great noise.Wear and tear disproportionately high, and often make hammer damage.Also often occur that burr is partly upwards dug and therefore can not be removed.
According to EP 654 313 B1, use is fixed on that hammer in the roll circumference of quick rotation is realized particularly fast but the burr that also noise is large is removed, and these hammers impact into fritter by the burr in the lower edge of the slab moving on cylinder with high cycle.This burr removal device has the hammer of auto retractable on its circumference, and the head of these hammers is described envelope curve when rotor rotates.Rotor has central shaft, is fixed with the guide bearing of form of annular rings on this central shaft in each end.Adjacent and be provided with relative to one another multipair guide bearing half portion of semicircular rings form between these guide bearings, wherein, guide bearing half portion to central shaft longitudinally on equably separately.At this, guide bearing half portion in guide bearing half portion of every pair staggers with respect to another guide bearing half portion in this right guide bearing half portion in the vertical.Guide bearing and guide bearing half portion hold the hinge drawbar unit that is parallel to center shaft axis, and carry hammer.
High wearing and tearing and for the burr part of splashing and hammer partly and noise to carry out necessary protection be main shortcoming except equipment cost.Particularly disadvantageously, with the central axes of burr removal device, be that the coaxially arranged bar consisting of guide bearing must be pulled out completely, to all hammers that are fixed on bar can be left behind from bar, and change separately or fully where necessary when there are wearing and tearing.This realizes all being upwards arranged in week in the axial bar situation in center.In most situation, in equipment or the roller-way at continuous casting installation for casting, side direction is not pulled out the required space of bar, therefore in order to mount and dismount hammer, must respectively the axle of whole burr removal device be unloaded, to can carry out hammer installation and removal outside roller-way.
Task of the present invention is to provide the burr removal device of the described type of a kind of introductory song part, wherein, due to wearing and tearing or for maintenance object, can have selection pointedly, save time and cost and change single hammer.
