Abstract
Disclosed are a method and a corresponding continuous casting machine (1) for continuously rolling a metal bar, particularly a steel bar, which is produced at a casting speed and the cross section of which is configured as a thin slab. Said metal bar is bent, dressed, and cut to length as required during cooling and is fed into a first roll stand for rolling once the temperature has been equalized. Optionally the metal bar can still be fed by modifying the casting machine by supporting a vertically cast continuous slab (2) having a guide length that is adjusted to the casting rate. One or several segments of said continuous slab is/are then dressed by bending and straightening, whereupon the continuous slab is guided by a sling, which is supported from below, into a straightening driver (6) that is positioned at a distance approximately equivalent to the length of the sling before being cut to length.
Description
The present invention relates to a kind of method, this method is used for one of continuous rolling and is metal strand, especially steel continuous casting billet thin slab, that produce with casting rate on cross section, this steel continuous casting billet is bent in the state of cooling, aligns, crosscut and be delivered into according to homogenizing temperature and be used for the first rolling mill stand as required, the invention still further relates to a corresponding conticaster.
This method is used for so-called thin slab, and its casting thickness is the 50-90 millimeter and is rolled into steel band.Compare with roll line with common continuous casting installation for casting and can save the energy and processing charges significantly.Preferably use two kinds of diverse ways, but they can access identical result for this reason.A kind of method is, one 90 millimeters the thin slab and be thinned to 15 millimeters in a plurality of rolling levels of casting.The cooling that produces during attenuate compensates by the eddy-current heating station of a respective length again.Then reel and approach steel band and place a moist closet the inside.Then can debatching and rolling again in a hot rolling line.Other method is to use a cast gate metal mold, the thin steel band of about 50 millimeters thick of its formation.The outlet of so-called CSP (the compact steel band processing of co rice pact strip production/) technology has an infeed set-up, the steel band of having cast in this device is become certain-length by crosscut, then each length section is placed an equalizing furnace that is used for making the temperature of steel strips homogeneous.An of short duration inactive state of described roll line compensates by equalizing furnace, keeps each length section in equalizing furnace.Steel band can move as casting rate with higher speed in addition, therefore has spacing between steel band.An additional furnace superintendent is as breeze way in addition.Continuous operation always is filled to this free space for the described casting machine of the inactive state of milling train.
For example by rolling temperature retention time decision demand or for the casting rate different with mill speed by furnace superintendent (so-called semicontinuous rolling) decision demand.
The design of described casting machine must be determined according to rolling principle.Later change, for example transform to the restriction that continuous rolling is subjected to casting machine and may produce king-sized reconstruction up to the reconstruction Equipment Foundations.
The technical problem to be solved in the present invention is also can change rolling mill practice afterwards from begin to design continuous casting installation for casting, make like this.So be devoted to also can realize continuous rolling afterwards with existing conticaster.
Solve like this technical problem that is proposed according to the present invention, make continuous casting billet in one or more segmentations, rectify curved with one with guide length that casting rate is coordinated mutually under the condition of supporting vertical casting and continuous casting billet sclerosis and from the loop of surface bearing down, before crosscut, directing into an aligning drive unit that departs from the setting of loop length slightly at one.The advantage of this loop is a buffering since this can the balance continuous casting billet when being buffered in continuous rolling and rolling between speed difference.In vertical continuous casting guiding, take preventive measures, therefore can prolong the continuous casting supporting that is used for higher casting rate by adding a supporting section.
Can monitor described loop according to required mill speed.
Consider that according to another measure the bearing length of length can be cast with about 8 to 12 meters/minute casting rate.
By shown in method can to produce a sclerosis thickness be 50 to 70 millimeters thin slab.
In addition advantageously, described continuous casting billet is rectified curved in the outlet of loop.Therefore consider the different amounts of deflection of loop according to the importing angle that changes.
At this advantageously, described thin slab is rolled with about 50 millimeters thickness when casting rate rises to the rolling pan feeding speed of first rolling machine frame.
According to another modification, described continuous rolling also can be used in practice like this, for thicker casting thickness, make by liquid phase core attenuate (LCR (Liquid-Core-Reduction)) as 60 to 70 millimeters how to reduce the rolling thickness of making every effort to reach, make to be hardened in continuously to need not to prolong ground in the existing continuous casting supporting and finish.Also can take the indemnifying measure of casting/mill speed in this case for corresponding loop.
Corresponding conticaster, it is prepended to a roll line and is the metal strand of thin slab on the cross section of can casting on this conticaster for continuous rolling, especially steel continuous casting billet, wherein have one vertical, be suitable for the continuous casting supporting of casting rate, connect at least one bending driving device thereon, an aligning drive unit, an infeed set-up, the continuous furnace and first rolling machine frame, in order to realize that continuous rolling constitutes thus, promptly, have a free space that extends under the zero level alignment substantially between the drive unit at bending driving device and aligning, deep-seated at the maximum loop of continuous casting billet is set therein puts the roller section that can rise and descend.Keep the advantage of true vertical, symmetry sclerosis and use present dummy bar system at this.
Another feature regulation, the formation of described loop are monitored by the aligning drive unit and monitoring casting/mill speed compensation thus.
Even more advantageously, employed continuous casting billet metal mold is a CSP cast gate metal mold.
Described casting apparatus can be got ready thus for higher casting rate,, can add another supporting section at least when speed increases that is.
Changing afterwards under the situation of rolling strategy, is favourable if at first be arranged on bending driving device on the special supporting structure.
Can make full use of the dummy bar system for existing equipment.Therefore it is favourable can carrying a dummy bar vertically downward for vertical casting machine.
Another selection according to device type is that described dummy bar can move up in described aligning drive unit back on zero level.
This is also had an advantage, on zero level, have one can be traversing the auxiliary roller-way that is used for continuous casting initial sum dummy head.
Other feature is to have a gas cutting device for urgent cutting outfit at the bending driving device place.
