Compared with the prior art, the utility model discloses simple structure has improved the high temperature resistance to deformation ability of the foot roller of square billet crystallizer, has improved foot roller life, has avoided the bleed-out risk of continuous casting process, has eliminated the side defect of taking off of square billet.
Description
Technical Field
The utility model relates to a ferrous metallurgy square billet continuous casting field especially relates to an improve structure that improves square billet crystallizer foot roll stability.
Background
The square billet crystallizer is the heart of the square billet continuous casting equipment, the square billet crystallizer and related components thereof need to work in a high-temperature environment for a long time, and the high-temperature stability of the square billet crystallizer and the related components has important influence on the continuous casting safety production and the square billet quality stability.
The foot roll of the square billet crystallizer is a component of the square billet crystallizer, is positioned at the tail end of an outlet of the crystallizer and is mainly used for supporting and guiding a steel billet which just leaves the crystallizer and is provided with a liquid core. The foot roller frame is fixed on the crystallizer body, the foot roller of the crystallizer is connected to the foot roller frame through a rotating shaft, in the continuous casting process, the foot roller of the crystallizer and the foot roller frame need to work under a high-temperature condition for a long time, bending and deformation are easy to occur in the later period of continuous casting, once the foot roller of the crystallizer and the foot roller frame deform, the risk of steel leakage can be brought, the square billet produced simultaneously can also have the defect of stripping, the internal cracks of the casting blank are caused, and great hidden dangers are brought to production and quality.
SUMMERY OF THE UTILITY MODEL
The problem to prior art exists, the utility model provides an improve the high temperature stability of the high crystallizer foot roll of square billet eliminates the safety risk of continuous casting in-process, improves the improvement structure of the crystallizer foot roll stability of square billet product quality.
The utility model is realized in such a way, and the improved structure for improving the stability of the foot roller of the square billet crystallizer; including four crystallizer foot roller units that the structure is the same, four crystallizer foot roller units fixed mounting are terminal at the crystallizer export, its characterized in that: the crystallizer foot roller unit comprises a gate type crystallizer foot roller frame, and a crystallizer foot roller arranged in the crystallizer foot roller frame through a foot roller rotating shaft; a wear-resistant shaft sleeve is arranged between the foot roller rotating shaft and the inner hole of the foot roller of the crystallizer; and a fixed connecting rod is welded between the adjacent foot roller frames of the crystallizer.
Preferably, in the above technical solution, the adjacent fixed connecting rods are located on the same horizontal plane and located at the center of the foot roller frame of the gate crystallizer.
In the above technical solution, preferably, the fixed link has a diameter
HRB400 rebar.
The utility model has the advantages that: compared with the prior art, the utility model discloses simple structure has improved the high temperature resistance to deformation ability of the foot roller of square billet crystallizer, has improved foot roller life, has avoided the bleed-out risk of continuous casting process, has eliminated the square billet's the square billet defect of taking off.

fig. 2 is a schematic view of the three-dimensional structure.
In the figure: 1. a crystallizer foot roll frame; 2. a foot roller of the crystallizer; 3. a foot roller rotating shaft; 4. fixing the connecting rod; 5. wear-resisting axle sleeve.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, an improved structure for improving the stability of a foot roller of a square billet crystallizer; the crystallizer comprises four crystallizer foot roller units with the same structure, wherein the four crystallizer foot roller units are fixedly arranged at the tail end of an outlet of a crystallizer, each crystallizer foot roller unit comprises a gate type crystallizer foot roller frame 1 and a crystallizer foot roller 2 arranged in the crystallizer foot roller frame through a foot roller rotating shaft; a wear-resistant shaft sleeve is arranged between the foot roller rotating shaft 3 and the inner hole of the foot roller of the crystallizer; a fixed connecting rod 4 is welded between the foot roller frames of the adjacent crystallizers; preferably, the fixed link is of a diameter
HRB400 rebar. The crystallizer foot roller frame in the structure is connected together in a mode of welding the connecting rod, and through the connecting mode, an interaction force is formed between the foot roller frames, so that the high-temperature stability of the crystallizer foot roller in the square billet continuous casting process can be improved, the steel leakage risk is avoided, the square billet desquamation defect is eliminated, and the stable connection between the square billet crystallizer foot roller frames is realized.
Preferably, in the above technical scheme, the adjacent fixed connecting rods are located on the same horizontal plane and at the center of the foot roller frame of the portal crystallizer, so as to ensure uniform stress on the foot roller frame of the mutual crystallizer and prolong the service life of the foot roller frame of the crystallizer.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
