Drawings
Fig. 1 is a schematic structural diagram of a novel dummy bar.
Detailed Description
The following describes in detail an embodiment of the present invention with reference to fig. 1.
As shown in fig. 1, the novel dummy bar comprises a dummy bar head 1, a guide device 2 and a transition link 3, wherein the guide device 2 is installed at the head of the dummy bar head 1, and the transition link 3 is installed at the connecting part of the dummy bar head 1. The novel dummy bar is a steel part.
The dummy bar head 1 comprises a head part 11 and a connecting part 13 connected with the head part 11, the head part 11 is rectangular in cross section and has a width larger than that of the connecting part 13, a receiving groove 14 is formed at the tail end (i.e. the end far away from the head part) of the connecting part 13 and is used for receiving and connecting the transition chain link 3, and a mounting hole 12 is formed at one end of the connecting part 13 close to the head part 11 and is used for matching with a relevant connecting mechanism of a continuous casting machine when the continuous casting machine is installed. The head part 11 and the connecting part 13 of the dummy bar head 1 are integrally manufactured and formed, such as casting.
The guide device 2 is in a quadrangular frustum pyramid shape, the size of the lower bottom surface is consistent with the size of the cross section of the head, the lower bottom surface of the guide device 2 is in contact with the head 11 and fixedly connected with the head 11 through bolts (not shown in the figure), and the size of the upper bottom surface of the guide device 2 is smaller than that of the lower bottom surface.
The transition chain link 3 comprises two chain links 4 which are arranged in parallel and have the same shape and size, one end of each chain link 4 is inserted into the accommodating groove 14, the other end of each chain link is exposed out of the accommodating groove 14, two shaft holes are formed in the part of each chain link 4 inserted into the accommodating groove 14, two mounting shafts 5 are inserted into the shaft holes of the two chain links 3 in sequence after being inserted into the mounting holes formed in the outer wall of the accommodating groove 14, the chain links 4 are fixed on the dummy head 1, and the part of each chain link 4 exposed out of the accommodating groove 14 is also provided with a mounting hole 41 for being connected with the other chain link.
Each link 4 is welded with a stopper 6 at a portion inserted into the receiving groove 14 for preventing the ingot rod from being separated from the ingot due to a change in arc of the ingot guide caused by resistance applied to the ingot during the guiding of the ingot.
Through the utility model discloses, can be under the condition that does not change the shape of original dummy bar head can simple efficient installation dummy bar head to can not change the radian of dummy bar at the casting blank in-process.
