Description

Technical Field

[0001] This utility model relates to the field of metallurgical continuous casting equipment technology, specifically a slab turning device for a continuous casting machine. Background Technology

[0002] In the continuous casting process of slabs, wide-section slabs are prone to bending deformation due to cooling stress or stacking pressure. In particular, downward-bending slabs are prone to interference with the roller conveyor surface when running on the conveyor, leading to problems such as poor conveying, accelerated equipment wear, and reduced production efficiency. Existing technologies lack dedicated slab flipping tools that are simple in structure and easy to operate, making it difficult to quickly and safely achieve slab flipping. Utility Model Content

[0003] The present invention aims to solve the above problems, thereby providing a slab turning device for continuous casting machines that is simple in structure, easy to operate, and safe and reliable.

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is: A slab turning device for a continuous casting machine includes a turning base, which is composed of a steel billet and has a wide side and a narrow side arranged opposite each other. A support component is fixedly installed on one wide side of the turning base to support the edge of the slab to be turned during the turning process. A hoisting connection component is fixedly installed on the turning base and on the other narrow side opposite to the support component to provide a hoisting connection point. The device also includes a hoisting execution component, which is connected to the turning base through the hoisting connection component to connect to a crane hook and transmit lifting force. The supporting assembly includes at least two symmetrically arranged supporting members, the bottom surface of which is flush with the narrow surface of the flipping base, so that the slab to be flipped can be stably flipped by relying on the supporting members during the lifting and flipping process.

[0005] Furthermore, the length of the flipping substrate is less than the length of the slab to be flipped, and its width is greater than or equal to the width of the slab to be flipped. Its thickness meets the structural strength requirements to withstand the load during the flipping process.

[0006] Furthermore, the support member is a plate-shaped structure with a width less than half the width of the narrow side of the slab to be flipped; to ensure that when flipped to an upright state, the slab to be flipped can detach from the support member due to its own weight and flip to the other side.

[0007] Furthermore, the support member is fixedly connected to the flipping base by welding, and the bottom surface of the support member is flush with the narrow surface of the flipping base.

[0008] Furthermore, the hoisting connection assembly includes at least two hoisting points, symmetrically arranged on the narrow surface of the flipping base.

[0009] Furthermore, the hoisting execution assembly includes a lifting ring, a connecting chain, and a connector. The lifting ring is used to connect to the overhead crane hook, and the connecting chain is connected to the lifting ring and the hoisting connection assembly respectively through the connector.

[0010] Furthermore, the rated loads of the lifting ring, connecting chain, and connecting piece are all greater than or equal to three times the total weight of the flipping device and the slab to be flipped.

[0011] Furthermore, the supporting components of the supporting assembly are arranged symmetrically along the length direction of the flipping base.

[0012] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: When using this invention, first place the billet-turning device flat in the designated position, then place the billet to be turned flat on the support assembly. Next, connect the lifting execution assembly via a crane hook and slowly raise the hook. As the hook rises, the billet-turning device and the billet to be turned gradually stand upright until they are nearly vertical. At this point, due to the narrow width of the support assembly, the billet to be turned flips to the other side under its own weight, thus achieving the billet turning operation. The structure is simple, the operation is convenient, it can utilize scrap steel billets, it is inexpensive, and it can quickly and safely achieve billet turning, making it highly practical.

[0014] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0015] See Figures 1-3 A slab turning device for a continuous casting machine includes a turning base 1, a support component 2, a hoisting connection component 3, and a hoisting execution component.

[0016] The flipping base 1 is composed of a steel billet, the length of which is less than the length of the slab to be flipped, between 1 / 2 and 2 / 3 of the length of the slab to be flipped, the width is greater than or equal to the width of the slab to be flipped, and the thickness is greater than or equal to 100mm.

[0017] The support assembly 2 includes two symmetrically welded support members on the wide side of one side of the flipping base 1. The support members are plate-shaped structures, and their width is less than half the width of the narrow side of the slab to be flipped. This ensures that when the slab to be flipped is flipped into an upright position, the center of gravity is located on the side of the support member away from the flipping base 1, and the bottom surface is strictly flush with the narrow side of the flipping base 1. The support members and the flipping base 1 are connected by a bevel weld, and the weld height must meet the strength requirements.

[0018] The lifting connection assembly 3 includes two symmetrical lifting points welded to a narrow surface on the other side of the flipping base 1. The distance between the lifting points is less than the length of the flipping base 1. The lifting points and the flipping base 1 are connected by bevel welding, and the welding area meets the strength requirements.

[0019] The lifting assembly includes a lifting ring 6, a connecting chain 4, and a U-shaped shackle. The lifting ring 6 is sized to fit the overhead crane hook. The connecting chain 4 is connected to the lifting ring 6 and the lifting connection assembly 3 via U-shaped shackles 5. The rated loads of the lifting ring 6, connecting chain 4, and U-shaped shackles 5 are all greater than or equal to three times the total weight of the slab turning device and the slab to be turned.

[0020] In use, place the billet flipping device flat in the designated position, place the billet to be flipped flat on the support component 2, connect the lifting ring of the lifting execution component through the crane hook, and slowly raise the hook. As the hook rises, the billet flipping device and the billet to be flipped gradually stand upright to a near-vertical state. At this time, due to the small width of the support component, the billet to be flipped flips to the other side under its own weight, completing the flipping operation.

[0021] With its simple structure and convenient operation, it can utilize scrap steel billets for reprocessing, resulting in low cost. It can also quickly and safely achieve slab flipping, making it highly practical.

[0022] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
