Abstract
The utility model relates to a flexible dummy bar for a metal continuous caster with complex spring steel sheet connection structure, which is composed of a dummy head, a caudal segment, and a bar body, wherein, the bar body is mainly composed of some separate segment blocks and a spring steelplate. The inner arc surface of the bar body is a free and flat spring steel plate; the outer arc surface of the bar body is a series of spring steel plates which are uncertain arcs in a free state. A bar body is formed by that the spring steel plates of the inner and the outer arc surfaces are integrally connected with the segment blocks by bolts and pins. The utility model has the advantages of simple and reasonable structure, difficult deformation, and long service life. The utility model is suitable for arc and straight arc types of continuous casters.
Description
The utility model belongs to metal continuous casting steel machine technical field.Be applicable to the arc and the straight circular-arc type continuous casting machine of the flexible or rigid dummy bar of present use.
Be used for the flexible dummy bar that continuous casting of metal is produced at present, as shown in Figure 1 and Figure 2, be grouped into by dummy bar head (a), periproct (c) and rod body.Be characterized in that the rod body branch comprises that some have the discrete joint piece (b) of connecting pin axis hole, each discrete joint piece is by bearing pin (d) the node composition shaft that is connected as a single entity.Bearing pin that this dummy bar shaft connects and hole must keep strict tolerance, and node is many more, and accumulated error is big more; The bearing pin junction is difficult for lubricated again, and wearing and tearing easily strengthen gap, node junction in the use, directly causes the shake and the play of dummy bar in the continuous casting production process, very easily causes the starting bleedout, increases the continuous casting production cost.
The purpose of this utility model is to provide a kind of metal continuous cast machine rigid and flexibility dummy bar of compound spring steel plate syndeton of simple in structure, not yielding, long service life, inherent characteristics by the seamless connectivity that it adopted, stop continuous casting and open the dummy bar play phenomenon of watering, reduce starting bleedout rate, improve to open and water success rate, reach the purpose that reduces the continuous casting production cost.
Task of the present utility model is finished as follows: i.e. the bearing pin syndeton of discrete joint piece in the existing dummy bar shaft of cancellation, adopt compound spring steel plate syndeton, based on this goal of the invention, the metal continuous cast machine rigid and flexibility dummy bar of compound spring steel plate syndeton of the present utility model is grouped into by dummy bar head (1), periproct (3) and rod body.It is characterized in that described shaft part saves piece (2), intrados steel spring plate (4), extrados steel spring plate (5), bolt (6) and pin (7) by dispersing and forms, described intrados steel spring plate is the straight steel spring plate of free state, described extrados steel spring plate is that free state is the not steel spring plate of specific arc, and inside and outside cambered surface steel spring plate and joint piece are by bolt (6) and (7) the composition shaft that is connected as a single entity.
Described discrete joint piece can be some more than two or two.
Described intrados steel spring plate can be a Monolithic spring steel plate, also can be that some steel spring plates combine, and described extrados steel spring plate can be a Monolithic spring steel plate, also can be that some steel spring plates combine.
The length overall of the utility model dummy bar is a 6-20 rice.
The utility model dummy bar shaft joint piece connects uses steel spring plate, can adopt the rustproof spring steel plate through Quenching Treatment, also can adopt common hot rolling steel spring plate.
The utility model dummy bar shaft joint piece can adopt cast steel, forged steel, also can adopt the welding steel manufacturing, and cure process can be adopted in joint piece surface, also can not adopt cure process.
Compared with prior art, the utlity model has following advantage: simple and reasonable for structure, not yielding, long service life, and the inherent characteristics by the seamless connectivity that it adopted, stop continuous casting and open the dummy bar play phenomenon of watering, reduce starting bleedout rate, improve to open and water success rate, reach the purpose that reduces the continuous casting production cost.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the dummy bar of available technology adopting.
Fig. 2 is an A-A profile among Fig. 1.
Fig. 3 is the structural representation of facing of the utility model dummy bar.
Fig. 4 is the plan structure schematic diagram of the utility model dummy bar.
Fig. 5 is a B-B profile among Fig. 3.
A is a dummy bar head among Fig. 1, Fig. 2, and b is discrete joint piece, and c periproct, d are bearing pins.
Among Fig. 3, Fig. 4, Fig. 5, the 1st, the utility model dummy bar head, the 2nd, the discrete joint of the utility model piece, the 3rd, the utility model periproct, the 4th, intrados steel spring plate, the 5th, extrados steel spring plate, the 6th, bolt, the 7th, pin.
Embodiment:
Adopt the utility model dummy bar shown in Figure 2 to be successfully applied in certain manufacturer's billet continuous casting machine, obtained the achievement of not having the bleedout of once starting to walk so far, this conticaster dummy bar parameter is: radius 10300mm, and length is 20000mm, cross dimensions is 210*150mm/mm.
