Abstract
The utility model provides a self-locking elastic dummy bar for arc type continuous casting machine with stationary drawn steel, comprising a dummy head, a telson, and a bar body. The inner arc surface of the bar body is a common spring plate, while the outer arc surface of the bar body is a series of supporting chain links connected via self-locking pin shafts in a row. The top of the supporting chain link is connected with the outer arc surface of the common spring plate into integration via bolts. The utility model has a reasonable structure, no interstice bounce, diminished bleedout rate during starting drawn steel, long service life, capability of satisfying the operation of arc section and the deposit of the horizontal section, and restriction of the curvature radius of the dummy bar bending towards the inner arc.
Description
The utility model belongs to continuous casting, relates in particular to the flexible dummy bar of billet caster.
The flexible dummy bar of camber conticaster is used for sealing the crystallizer end opening, when watering steel continuously, fuses with strand, casting path along the conticaster bending, by guide roller, The drawing straightener steel billet is pulled out, separate with steel billet then, be transplanted on the storing unit with horizontal.The flexible dummy bar of existing billet caster mostly is the flexible dummy bar of De Make company, and its shaft is connected as a body before and after crossing bearing pin by a series of links, can be by certain radian to the inner arc bending.Because chain link connects by bearing pin, axis hole in service constantly rotates wearing and tearing, and the gap of axis hole and bearing pin is increased, and it is moving and cause dummy bar to shake to produce the gap string when steel is drawn in starting, thereby steel bleed-out accident occurs drawing.By the same token, dummy bar moves sideslip in roller-way meeting in service because of laterally going here and there, thereby can't enter the dummy ingot mouth, influences throwing preparation.In addition, this kind dummy bar is short service life, the maintenance cost height.
It is moving not have the gap string when the purpose of this utility model is to provide a kind of operation, draws steel steady, the self-locking elasticity dummy bar of long service life.
The utility model is to realize like this, dummy bar is by dummy bar head, periproct and shaft are formed, shaft comprises a public latch plate and a series of supporting chain section, public latch plate is positioned on the operation intrados of shaft, supporting chain section is positioned on the operation extrados of shaft, one end of supporting chain section is a spill, the other end is a convex, centre position at the spill place laterally has the pair of pin axis hole, laterally have an oblate pin-and-hole in the centre position at convex place, the female end of each supporting chain section and the male end of another supporting chain section connect into row with the self-locking bearing pin, and the extrados of top and public latch plate is connected as a single entity by bolt.More firm for public latch plate is connected with supporting chain section, a side that links to each other with public latch plate at the top of supporting chain section both sides vertically is provided with the groove shoulder.
The utility model is rational in infrastructure, and no gap string is moving, has reduced starting and has drawn the steel breakout ratio, has improved slab quality, and long service life has reduced spare parts consumption, and the lifting job when being convenient to installation and maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic side view of self-locking elasticity dummy bar.
Fig. 2 is the perspective diagram of supporting chain section.
Fig. 3 is the vertical view of supporting chain section.
Fig. 4 is the side view of supporting chain section.
Fig. 5 is the structural representation of dummy bar shaft.
This dummy bar is by dummy bar head 1 as we can see from the figure, periproct 9 and rod body are grouped into, the inner arc of shaft is public latch plate 2, outer arc is a series of supporting chain sections 4 that are linked to be a row with self-locking bearing pin 5, one end of supporting chain section 4 is a spill, the other end is a convex, centre position at the spill place laterally has pair of pin axis hole 10, laterally have an oblate pin-and-hole 11 in the centre position at convex place, the male end of the female end of each supporting chain section 4 and another cartridge 4 connects into a row with self-locking bearing pin 5, and dummy bar head 1 and periproct 9 were adopted in the same way with being connected also of shaft.Separated by a distancely at the top (comprising periproct 9) of supporting chain section 4 have two screws 13, be connected as a single entity with the outer arc side of bolt 3 with public latch plate 2.6 is connecting link among the figure, and 7 is guide roller, and 8 are the straightening roller.The major axis of the oblate pin-and-hole 11 of supporting chain section 4 male end and minor axis difference are the gap of self-locking bearing pin 5 and pin-and-hole, and this gap should be more than or equal to the distance of elasticity dummy bar in 4 elongations of segmental arc supporting chain section.The big I restriction elasticity dummy bar in this gap is to the radius of curvature of inner arc bending, and dummy bar is to set according to the arc radius of circular-arc type continuous casting machine to the radius of curvature of inner arc bending.In the installation and maintenance process, the normal anti-phenomenon of hanging of appearance, and cause public latch plate 2 decurvations distortion to overstep the extreme limit and fracture, adopting the self-locking bearing pin is exactly in order to limit the radius of curvature of elasticity dummy bar to the inner arc bending, prevents that public latch plate 2 from surpassing elastic deformation limit and fracture to inner arc flexural deformation.Laterally string is moving in order to limit public latch plate 2, and a side that is connected with public latch plate 2 at the top of supporting chain section 4 both sides vertically is provided with groove shoulder 12, and public latch plate 2 is set in this groove shoulder 12.In the joint of public latch plate 2, adopt connecting link 6 that its two ends are fused, the structural similarity of connecting link 6 and supporting chain section 4 is only opened two screws 13 more in the middle of original two screws 13, so that connect more firm.For the ease of making, transport, installing, this dummy bar can be prefabricated into multistage, is generally three sections, to on-the-spot assembling, uses connecting link 6 to connect.Supporting chain section 4 requires long-term indeformable under the calendering of straightening roller 8, should select for use medium carbon steel to make, and public latch plate 2 should be selected the high-strength alloy steel plate for use, after heat treatment has very high intensity and elasticity.The utility model can satisfy the operation of segmental arc and depositing of horizontal segment, can limit the radius of curvature of dummy bar to the inner arc bending again.
