Other advantage of the utility model and characteristic obtain from the following explanation that non-restrictive example is done, and wherein with reference to following accompanying drawing, accompanying drawing illustrates:
Fig. 1 is the sketch map of vertical continuous casting equipment together with the vertical section of a plurality of continuous casting billet guiding segmentations,
Fig. 2 is the sketch map of vertical continuous casting equipment together with the vertical section of pinch roll frame,
Fig. 3 is that the intercepting part of Fig. 1 is guided segmentation together with cutting machine, residue steering gear and continuous casting billet,
Figure 4 and 5 are perspective views of residue steering gear.
The specific embodiment
In Fig. 1, schematically show the continuous casting installation for casting 1 that is configured to vertical continuous casting equipment vertical part surface together with member important for the utility model.Vertical strand guide installation 3 on this continuous casting installation for casting 1 comprises crystallizer 2 and is connected this crystallizer 2; Wherein in casting cycle, in said crystallizer 2, molten steel casting become to have the casting continuous casting billet 4 of slab cross section; And in said strand guide installation 3, quantity-produced casting continuous casting billet 4 is cooled off, guides, supports, cuts to slab 19 by means of cutting machine 6 scales, wherein by means of slab lift 20 slab is transferred out from strand guide installation 3 subsequently.Said strand guide installation 3 comprises two row strand-guiding roller 5a and 5b, and said strand-guiding roller 5a and 5b merge into a plurality of continuous casting billet guiding segmentations, in said continuous casting billet guiding segmentation, shows four continuous casting billet guiding segmentation 11a typically to 11d.Be supported on to one row strand-guiding roller 5a fixed-site on the outside of continuous casting billet guiding segmentation; Secondary series strand-guiding roller 5b is then can be arranged in the inboard of continuous casting billet guiding segmentation with respect to the mode of first row strand-guiding roller 5a motion.This relative motion property is adjusted to desired thickness of strand or reduces thickness such as allowing for the casting continuous casting billet of liquid core for having still.Like what in Fig. 3, be shown specifically, strand-guiding roller 5a and the 5b with being in the inside that are in the outside are bearing in the scaffold 9 with the mode that can rotate.The strand-guiding roller 5c that among said strand-guiding roller 5a, the 5b some are configured to drive and/or be configured to the strand-guiding roller 5d that can depress and the speed of confirming casting continuous casting billet 4.Arranged the cutting machine 6 that is configured to spontaneous gas cutting machine along continuous casting billet throughput direction R in the back of continuous casting billet guiding segmentation 11c, this cutting machine 6 continuous casting billet 4 of will casting is cut to the slab 19 with particular length.When cutting casting continuous casting billet 4 by means of cutting machine 6; At first the thermal-flame continuous casting billet 4 of will casting that adds through cutting nozzles 21 is heated to ignition temperature and subsequently oxygen is blown on the position of heating, makes the burning and under high pressure from the cutting slit, blowing out in cutting oxygen in the zone in cutting slit of casting continuous casting billet 4.Oxide is also referred to as the cutting residue usually, has than the remarkable lower fusing point of steel and also has the liquid state more.Residue is blown out from the cutting slit by the oxygen beam, guides cutting nozzles 21 along the cutting slit continuously simultaneously.Invade along continuous casting billet throughput direction R and be arranged in the strand guide installation 3 of cutting machine 6 back and especially prevent cutting residue is rolled in the continuous casting billet 4 of casting in order to prevent to cut residue; The residue steering gear 7 that before the beginning cutting operation, will be arranged in cutting machine 6 back by means of manipulation device 8 places steering position from the off-position, wherein in the off-position, said residue steering gear 7 is not pressed down on the casting continuous casting billet and in steering position then residue steering gear 7 to be pressed down on the casting continuous casting billet.After cutting casting continuous casting billet 4, again said residue steering gear 7 is moved back into the off-position from steering position.
Certainly, as shown in figure 2, said strand guide installation 3 also can comprise pinch roll frame 12.About the function of the utility model, do not exist difference, thereby with reference to Fig. 1.
In Fig. 3, show in detail residue steering gear 7 by Fig. 1.This residue steering gear 7 is arranged in the back of cutting machine 6 along continuous casting billet throughput direction R, and wherein this residue steering gear 7 is suspended on the suspension arrangement 10 that is configured to the chain type suspension, and this chain type suspension 10 is connected with the manipulation device that is configured to pneumatic linear actuator 8 through slewing rollers 18.In the F of off-position, said residue steering gear 7 is not depressed on the casting continuous casting billet 4.Casting continuous casting billet 4 is cut in beginning by means of cutting machine 6 before, by means of manipulation device 8 residue steering gear 7 is pressed down on the casting continuous casting billet 4, wherein said residue steering gear 7 is pressed on the casting continuous casting billet 4 through its deadweight.When cutting, cutting machine 6 on guide rail 22 with casting continuous casting billet 4 same moved further, thereby transverse to continuous casting billet throughput direction R continuous casting billet 4 incisions of will cast.The cutting residue that in this process, produces is blown out through the cutting slit by cutting nozzles 21 and partly in steering position A, captures 17 captures of deflecting plate that are disposed in the back in other words by residue steering gear 7, guides such as continuous casting billet at ensuing strand guide installation and is rolled among the segmentation 11d in the continuous casting billet 4 of casting thereby guarantee will not cut residue.
In Figure 4 and 5, show in detail the situation that the cutting residue is cooled off and from residue steering gear 7, discharges.As can be from finding out these accompanying drawings, said residue steering gear 7 be configured to box-shaped profile 13 and the coupled U-shaped profile 14 that connects, and said U-shaped profile 14 is arranged in the front of box-shaped profile 13 along the continuous casting billet throughput direction.Box-shaped profile 13 has and is used for water swivel 15 that residue steering gear 7 is cooled off, and wherein cooling water imports in the U-shaped profile 14 by means of two connecting lines 16 after flowing through box-shaped profile 13, and the cutting residue that cooling water will produce in U-shaped profile 14 washes away.Advantageously, mainly in steering position, the cutting residue cooled off just on residue steering gear 7 being pressed down to the casting continuous casting billet time and will cut residue in other words and from residue steering gear 7, discharge.The cooling water of being discharged is discharged from the strand guide installation of continuous casting installation for casting by the deflecting plate that is arranged in the back with the cutting residue of being discharged.
