Technical Field

[0001] The utility model relates to the technical field of ingot moulds, in particular to an ingot mould with reinforced trunnions. Background Art

[0002] An ingot mould is a large-scale ingot casting device that is essential for the ingot casting production in a steel mill and is used repeatedly. Molten steel is poured into the ingot mould to cool and form. A trunnion is a stress-bearing member connected to both sides of the ingot mould for supporting the hoisting of the ingot mould. Since the ingot mould is heavy after pouring, and the trunnion is perpendicular to the ingot mould, that is to say, the trunnion is horizontally arranged and the ingot mould is vertically hoisted. In this case, at the lower side of the contact area between the trunnion and the ingot mould, that is Figure 3 the M point in Summary of the Utility Model

[0003] Aiming at the technical problem that the lower side of the contact area between the trunnion and the ingot mould in the prior art cracks, and the trunnion warps after long-term use, the utility model provides a steel ingot mould with reinforced trunnions, which is characterized in that a diagonal support part is arranged between the trunnion and the ingot mould, and the diagonal support part can resist a part of the vertical downward gravity exerted by the ingot mould on the trunnion, so as to reduce the traction force exerted by the ingot mould on the trunnion. The specific technical solutions are as follows:

[0004] The present application provides an ingot mould with reinforced trunnions, which includes an ingot mould and trunnions horizontally connected to both sides of the ingot mould, and a diagonal support part is arranged at the contact area between the ingot mould and the trunnions to form a triangular support structure.

[0006] As a further technical solution of the utility model, the distance from the contact area between the diagonal support part and the trunnion to the ingot mould is L1, and the axial length of the trunnion is L, and L1 > L / 2.

[0007] As a further technical solution of the utility model, N groups of diagonal support parts are arranged, N is a multiple of 2, and the N groups of diagonal support parts are evenly arranged circumferentially around the trunnion.

[0010] The beneficial effects of the utility model are as follows:

[0011] In this application, a diagonal bracing part is arranged between the trunnion and the ingot mold. The diagonal bracing part can resist a part of the vertically downward gravity exerted by the ingot mold on the trunnion, thereby reducing the traction force exerted by the ingot mold on the trunnion, increasing the service life of the trunnion, and reducing the possibility of upward warping.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0017] This application aims at the technical problems that cracking occurs on the lower side of the contact area between the trunnion and the ingot mold in the prior art, and the trunnion warps upward after long-term use; a diagonal bracing part is arranged between the trunnion and the ingot mold, and the diagonal bracing part can resist a part of the vertically downward gravity exerted by the ingot mold on the trunnion, thereby reducing the traction force exerted by the ingot mold on the trunnion.

[0018] The ingot mold with a reinforced trunnion includes an ingot mold 100 and trunnions 200 horizontally connected to both sides of the ingot mold 100. A diagonal bracing part is arranged at the contact area between the ingot mold 100 and the trunnions 200 to form a triangular support structure; the diagonal bracing part can resist a part of the vertically downward gravity exerted by the ingot mold on the trunnion, thereby reducing the traction force exerted by the ingot mold on the trunnion, increasing the service life of the trunnion, and reducing the possibility of upward warping.

[0019] In the ingot mold with a reinforced trunnion, there is an included angle a between the diagonal bracing part and the trunnion 200, and a > 45°; that is to say, in this way, the length of the diagonal bracing part in the vertical direction is greater than its length in the horizontal direction, which is beneficial to resisting the vertically downward gravity.

[0020] In the ingot mold with a reinforced trunnion, the distance from the contact area between the diagonal bracing part and the trunnion 200 to the ingot mold 100 is L1, and the axial length of the trunnion 200 is L, and L1 > L / 2; in this way, it can be ensured that the contact area between the diagonal bracing part and the trunnion 200 is on the side of the center of gravity of the trunnion 200 far from the ingot mold 100, which can improve the support surface for the trunnion 200.

[0021] In the ingot mold with reinforced trunnions, there are N groups of diagonal braces, where N is a multiple of 2, and the N groups of diagonal braces are evenly arranged circumferentially around the trunnion 200. That is to say, the number of diagonal braces is an even number, and each diagonal brace has another diagonal brace that is symmetrical to it. In this way, the two mutually symmetrical diagonal braces can further enhance the resistance effect against the gravity of the ingot mold.

[0022] Embodiment 1

[0023] Figure 1 Shows a schematic structural diagram of Embodiment 1; Figure 1 In it, the diagonal brace includes a support rod 300. Using the support rod 300 as the diagonal brace can reduce the material consumption, and it only has two welding points, which is also relatively convenient for welding, and is suitable for ingot molds of heavy type and below.

[0024] Embodiment 2

[0025] Figure 2 Shows a schematic structural diagram of Embodiment 2; Figure 2 In it, the diagonal brace includes fins 400. The fins 400 have a thickness, and surface contact is formed between the fins 400 and the ingot mold 100 and the trunnion 200. Through the setting of the fins 400, the support effect can be further improved, and it is suitable for ingot molds of medium type and above.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
