Abstract
The utility model relates to an equipment part used for the metallurgical industry, and especially relates to a dummy bar used for metallurgy produced by a metallurgical continuous casting process round billet. The dummy bar is mainly used for solving the technical problem in the prior art that the square-to-round transition of the dummy bar between a bar head and a bar body is poor. The dummy bar comprises a dummy bar head (1) and a dummy bar tail (2), and is characterized in that a starting bar body (3) and more than one middle bar body are connected between the dummy bar head (1) and the dummy bar tail (2), and the starting bar body and all the middle bar bodies are arc-shaped.
Description
Technical field
The utility model relates to a kind of metallurgical industry and uses equipment component, and a kind of metallurgy that especially relates to the production of metallurgical continuous casting technology circle base is used dummy bar.
Background technology
Continuous casting is the main technique mode of modern metallurgy industry, particularly Iron and Steel Production, and conticaster is a task equipment of realizing continuous casting process.The round billet continuous casting machine is to be improved by billet caster; The maximum difference of itself and billet caster is the arc groove face that the roll surface of round billet continuous casting machine straightening machine must process a suitable width; To improve parcel property, reduce the distortion of depressing in the strand straightening process to strand; Because the dummy bar head is a cylinder, dummy bar is as square (rectangle) simultaneously, and the changeover portion that therefore connects dummy ingot shaft and dummy bar head must be realized the smooth and easy transition to circle by the side.Chinese patent discloses a kind of novel dummy bar device, and (Granted publication number: CN2579560), it comprises dummy bar, the changeover portion that is connected with dummy bar; Dummy bar head; Offer connecting hole on dummy bar head and the changeover portion, rotating shaft is connected with connecting hole, a device of limiting between dummy bar head and the changeover portion; Stopping means comprises the elastic plate that connects dummy bar head and changeover portion, the spacing seam between dummy bar head and the changeover portion; Spacing seam between dummy bar head and the changeover portion comprises the boss on the changeover portion, the boss on the dummy bar head, and the relative bottom surface contact of two boss, gapped between the side of a boss and the corresponding surface.But this dummy bar is transitional relatively poor to what justify by just between bar head and shaft.
The utility model content
The utility model provides a kind of metallurgy and uses dummy bar, its mainly be solve the existing in prior technology dummy bar between bar head and shaft by the side to transitional relatively poor etc. the technical problem of justifying.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of metallurgy of the utility model is used dummy bar, comprises dummy head and dummy bar tail, is connected with initial shaft and the middle shaft more than 1 between described dummy head and the dummy bar tail, and initial shaft and all middle shafts all are circular arc.All shafts are all for circular arc designs, and making can smooth and easy transition to circle by the side between bar head and the shaft.
As preferably, described dummy head is provided with groove, and initial shaft is provided with the projection that can insert groove, and cross-under has first bearing pin between groove and the projection, can dummy head and initial shaft be fixed together.
As preferably, cross-under has second bearing pin between described initial shaft and the middle shaft, can initial shaft and middle shaft be fixed together.
As preferably, the inside of shaft in the middle of described dummy bar tail the inner is inserted into, cross-under has the 3rd bearing pin between dummy bar tail and the middle shaft, and the 3rd bearing pin outer end is fixed with the pin clamp through connector.The pin clamp can prevent that the bearing pin end from exposing.
As preferably, described in the middle of shaft comprise by shaft in the middle of the shaft, the 3rd in the middle of the shaft, second in the middle of first and forming, fix through the 3rd bearing pin between each middle shaft.Each junction can be fixed through the bearing pin more than two.
Therefore, the utility model can carry out smooth and easy transition by the side to circle between bar head and shaft, simple and reasonable for structure.
