Abstract
The utility model provides an arc elastic dummy bar for an arc-shaped continuous casting machine, which is composed of a connecting bar, a dummy head, a transition segment and a bar body connected in turn. The back section of the bar body is a series of bar body chain links, the front section of the bar body comprises a series of supporting chain links and an arc spring plate, and the spring plate is fixed on the operation inner arc surface of the supporting chain links and the transition segment. The utility model with simple structure and reasonable design can simplify the guide equipment of a secondary cooling chamber, which profits to the maintenance of the equipment and the cleanness of the scrap steel of the secondary cooling chamber so as to improve the operation rate of a continuous casting machine.
Description
The utility model belongs to continuous casting technology, relates in particular to the flexible dummy bar of circular-arc type continuous casting machine.
The flexible dummy bar that uses on the present billet caster, comprise that my patent No. of application is 90225074, name is called the described dummy bar of Chinese patent of " self-locking elasticity dummy bar ", it all is arcuate guide frame along conticaster, pass through guide roller, make the dummy bar head enter the crystallizer end opening, finish throwing preparation.But the arcuate guide frame, particularly the existence of crystallizer below two cold house's guiders is drawn steel technological operation and maintenance of equipment to bring a lot of inconvenience.In case the bleedout accident takes place, the slag that leaks on two cold house's guiders is difficult to remove, and will cause dummy bar to move, thereby influence is produced.
The arc elasticity dummy bar that can save part two cold house's guiders when the purpose of this utility model is a kind of the operation is provided.
The utility model is achieved in that this arc elasticity dummy bar is connected in sequence by connecting rod, dummy bar head, transition segment and shaft, the back segment of shaft is a series of interconnective shaft chain links, the leading portion of shaft comprises a series of interconnective supporting chain sections and an arc spring plate, and this arc spring plate is fixed on the operation intrados of supporting chain section and transition segment.The outer arc radius of the used arc spring plate of the utility model is 3400mm, and its thickness is 12mm, and length is 1600mm, and width is 100mm, and its two ends are 60 ° of oblique angles.The side that the top of described supporting chain section and transition segment links to each other with arc spring plate both sides vertically respectively is provided with a groove shoulder.Supporting chain section is shorter than the shaft chain link, has one in the centre position of each supporting chain section and connects screw, is used for fixing the arc spring plate.
The utility model arc elasticity dummy bar is simple in structure, reasonable in design, uses this dummy bar can simplify the guide device of two cold houses, thereby improved continuous casting and drawn the steel technological operation, make things convenient for the maintenance of equipment, also helped the steel scrap of cleaning two cold houses, improved the operating efficiency of conticaster.
In conjunction with the accompanying drawings the utility model arc elasticity dummy bar is further described below by embodiment.
Accompanying drawing 1 is the structural representation of the utility model arc elasticity dummy bar and leading truck.
Accompanying drawing 2 is the front view of arc spring plate.
Accompanying drawing 3 is the vertical view of accompanying drawing 2.
Accompanying drawing 4 is the B-B cutaway view of accompanying drawing 3.
Accompanying drawing 5 is the front view of supporting chain section.
Accompanying drawing 6 is the vertical view of accompanying drawing 5.
Accompanying drawing 7 is the C-C cutaway view of accompanying drawing 5.
Accompanying drawing 8 is the front view of connecting link.
Accompanying drawing 9 is the vertical view of accompanying drawing 8.
Can see that from accompanying drawing 1 the utility model arc elasticity dummy bar mainly is connected in sequence by connecting rod 1, dummy bar head 2, transition segment 5, a plurality of supporting chain section 7, connecting link 15 and a plurality of shaft chain link 16.All chain links 7,15 and 16 structural similarity, one end is a spill, the other end is a convex, centre position at the spill place laterally has pair of pin axis hole 13, laterally have an oblate pin-and-hole in the centre position at convex place, the female end of each chain link and the male end of another chain link connect into row with the self-locking bearing pin, become shaft.The major axis of the flat pin-and-hole of chain link male end and minor axis difference are the gap of self-locking bearing pin and pin-and-hole, and this gap should be more than or equal to the distance of dummy bar in the elongation of segmental arc chain link.The big I restriction dummy bar in this gap is to the radius of curvature of inner arc bending.On the operation intrados of the supporting chain section 7 of shaft leading portion and transition segment 5, be equipped with an arc spring plate 6, have a screw 12 in the centre position of each supporting chain section 7, shown in accompanying drawing 5 to 7, corresponding position has screw 11 on arc spring plate 6, shown in accompanying drawing 3 and 4, pass screw 11 and 12 with screw rod, both are linked into an integrated entity.Be restriction arc spring plate 6 horizontal looseness, be preferably in side both sides vertically that the top of supporting chain section 7 and transition segment 5 is connected with arc spring plate 6 and respectively be provided with a groove and take on 14, take in 14 so that make arc spring plate 6 be set in groove.For making the dummy bar operational effect better, also can be provided with the groove shoulder at the top of shaft chain link 16, and stud with linear latch plate 17, on each shaft chain link 16, have two screws, in order to fixing linear latch plate 17, the application number that can consult my application is 96225074 Chinese patent.The utility model embodiment is that the circular-arc type continuous casting machine of 5250mm is an example with the arc radius R of segmental arc, and the outer arc radius of the arc spring plate 6 that is adopted is 3400mm, and thickness is 12mm, and length is 1600mm, and width is 100mm.The two ends of this latch plate 6 are 60 ° of oblique angles, so that can seamlessly transit by the straightening machine time, do not produce vibrations.For making connection more firm, can respectively increase a screw 11 at the two ends of arc spring plate 6, as shown in Figure 3.This just need set up a connecting link 15 between supporting chain section 7 and shaft chain link 16, see also accompanying drawing 8 and 9.The length of the used supporting chain section 7 of present embodiment is 270mm, and the length of connecting link 15 and shaft chain link 1.6 is 470mm.The difference of connecting link 15 and shaft chain link 16 is that the former has more two screws 12.The utility model arc elasticity dummy bar by the deadweight of dummy bar leading portion supporting chain section 7, makes arc spring plate 6 produce strain when horizontal roller moves, and is depressed into level.When running to two cold house segmental arcs, arc spring plate 6 returns to bowed state, dummy bar head 2 is during near the end opening of crystallizer, just near vertical, the distance of centre of gravity of supporting chain section 7 diminishes in the front portion of dummy bar, and the deadweight of supporting chain section 7 and dummy bar head 2 diminishes to arc outside bending moment to latch plate 6, arc spring plate 6 can overcome bending moment laterally, keep bowed state, in the arc radius track of conticaster, move, make dummy bar head 2 aim at the crystallizer end opening exactly.Calculate and evidence by theory, adopt the utility model dummy bar, can save the guider of the two epimere 1200mm to 1600mm of cold house length, comprise guide roller 9 and leading truck 10.For alleviating the deadweight of dummy bar, pit 19 has all been designed in all chain links 7,15 of the utility model and 16 both sides, shown in accompanying drawing 5 to 9.
