Description
Technical Field
The utility model belongs to the metallurgical equipment field, concretely relates to circle base conticaster dummy bar body structure.
Background
Continuous casting is a main process mode in modern metallurgy industry, particularly steel production, and a continuous casting machine is special equipment for realizing a continuous casting process. The round billet continuous casting machine is improved from a square billet continuous casting machine, and the biggest difference between the round billet continuous casting machine and the square billet continuous casting machine is that the roller surface of a withdrawal and straightening machine of the round billet continuous casting machine needs to be processed with an arc groove surface with a proper width so as to improve the wrapping property of a casting blank and reduce the reduction deformation in the withdrawal and straightening process of the casting blank; the dummy bar of the round billet continuous casting machine comprises a round billet dummy bar head assembling device, a middle section and a tail section, and an arc groove surface is arranged in the middle of a front section roller of the round billet continuous casting machine so as to be suitable for the operation of a front section round billet. Round billet dummy bar is because the number of sections is many, node junction is many, leads to node junction round pin axle wearing and tearing easily, and round pin axle wearing and tearing increase back, dummy bar mechanical properties seriously reduce, the easy problem that appears easily when round billet conticaster is used of body of rod structure deformation etc..
SUMMERY OF THE UTILITY MODEL
The utility model provides a round billet conticaster dummy bar body structure can strengthen the bearing capacity of dummy bar body, has solved the problem of dummy bar body unstability, striking each other.
The technical scheme of the utility model as follows:
a dummy bar body structure of a round billet continuous casting machine comprises a round billet dummy bar head assembly device, a middle section and a tail section, wherein two ends of each chain link of the middle section are processed into a convex shape and a concave shape, and a convex rear chain link and a concave front chain link are matched and movably connected through a pin shaft; the chain link comprises two side plates and a connecting plate, the two side plates are connected together by the connecting plate, an upper groove and a lower groove are formed between the connecting plate and the two side plates, a plurality of reinforcing plates which are continuously arranged are arranged in the upper groove, an interface between the two reinforcing plates is positioned in the middle of the connecting plate, and the reinforcing plates and the connecting plate are fastened together by bolt pairs.
The preferred scheme of the dummy bar body structure of the round billet continuous casting machine is that the top end of a bolt hole of each chain link is provided with a positioning hole, a positioning sleeve is tightly installed in the positioning hole, and the inner hole of the positioning sleeve is in clearance fit with a screw of the bolt pair.
The preferred scheme of the dummy bar body structure of the round billet continuous casting machine is that the connecting plate of the chain link below the joint between the two reinforcing plates is provided with four bolt holes, and the connecting plate of the chain link below the non-joint is provided with two bolt holes.
The preferable scheme of the dummy bar body structure of the round billet continuous casting machine is that the reinforcing plate material is high-quality steel and the thickness is 14-18 mm.
The utility model has the advantages that: the utility model discloses make dozens of festival connecting joints remain stable straight, not drunkenness, it is good to reach the wholeness ability, has effectually prevented internode striking and each festival that round billet caster dummy bar produced in process of production because of the drunkenness that the pulling rate is uneven to cause. Thereby improving the production operation efficiency of the continuous casting machine, avoiding quality accidents and loss and having obvious practical production effect.
