Description
Technical Field
[0001] The utility model relates to the technical field of ladle cover production, and more specifically, to a high-strength ladle cover. Background Art
[0002] As a casting tool commonly used by steel-producing enterprises, the improvement and research and development of ladle has intensified in recent years. At present, many enterprises have improved the ladle to reduce the temperature drop of molten steel or give the ladle a basic smelting function, adding electric heating, multi-layer insulation and other structures, aiming to heat and keep the molten steel warm during the transportation of the ladle, or directly optimize some small heating processes and complete the heating directly in the ladle, thereby avoiding frequent and unnecessary steps such as pouring and transferring molten steel, shortening the production cycle.
[0003] This leads to a problem. In order to keep the molten steel in the ladle warm and to facilitate simple heating operations, the ladle cover used in conjunction with the ladle is a simple cover body. Neither the structural strength nor the functionality can meet these optimization improvements. Therefore, the ladle cover must also be redesigned. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a high-strength ladle cover to solve one or more of the above-mentioned problems.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A high-strength ladle cover comprises a cover body, a self-locking docking piece is provided at the front end of the cover body, a pressure relief port is provided at the rear end of the top surface of the cover body, a reversible sealing plate is provided at the pressure relief port, a stopper is provided at the rear end of the pressure relief port, a lifting ear is also provided at the top of the cover body, and a plurality of V-shaped reinforcements with warped edges are embedded inside the cover body.
[0007] Furthermore, the lifting lug is obtained by welding four L-shaped frames, and the corners of the L-shaped frames are chamfered.
[0008] Furthermore, a turning cylinder is provided on the cover body, and the turning cylinder drives the blocking plate to turn.
[0009] Furthermore, the front end surface of the stopper has a slope, and the slope of the slope is not higher than 40°.
[0010] Furthermore, the pressure relief port is a sink structure as a whole, and the bottom surface of the sink structure is provided with at least one pressure relief through hole, and the pressure relief through hole is an upward-spraying expansion through hole.
[0011] Furthermore, the slot of the docking piece is tilted, the notch of the slot is open at the rear, and a reinforcing rib is provided between the docking piece and the cover body.
[0012] In summary, the utility model has the following beneficial effects: by setting up a special pressure relief structure to cooperate with the temporary heating operation of the ladle, the defect of the existing ladle cover being insufficient in function is compensated; at the same time, a modified reinforcement member is embedded inside to improve the overall structural strength of the ladle cover; the lifting ear structure of the ladle cover is improved to make the lifting process more stable; the self-locking part structure of the ladle cover docking with the ladle is improved to prevent the cover body from being rushed open when the pressure is released.

[0018] Example:
[0019] The following is combined with Figure 1-4 The utility model is described in further detail.
[0020] High-strength steel ladle cover, the main body is the cover body 10, with Figure 1 The viewing angle is based on Figure 1 As shown, a self-locking docking piece 11 is provided at the front end of the cover 10, and the slot of the docking piece 11 is inclined, specifically, the slot opening is offset and opened backwards. Compared with the docking slot opened vertically, this slot structure can effectively prevent the internal pressure from being too large, and the cover 10 is directly separated from the ladle by being flushed. A reinforcing rib is also provided between the docking piece 11 and the cover 10 to improve the structural strength.
[0021] like Figure 2 and Figure 3As shown, a pressure relief port 20 is provided at the rear center of the top surface of the cover body 10. The pressure relief port 20 can be a simple through groove. Preferably, the pressure relief port 20 is set as a sink structure, and a pressure relief through hole is provided at the center of the inner bottom surface of the sink structure, and the aperture of the pressure relief through hole does not exceed one-half of the width of the sink structure and is not less than one-fifth of the width of the sink structure. The pressure relief through hole is an upward spraying expansion through hole, that is, the pressure relief through hole is a smooth structure with a wide top and a narrow bottom, and the internal heat and pressure are fully dissipated outward and released. A reversible plugging plate 21 is provided at the pressure relief port 20, and a reversing cylinder 23 is provided at the rear of the setting position of the plugging plate 21. The reversing cylinder 23 is connected to the plugging plate 21, and the reversing cylinder 23 can drive the plugging plate 21 to flip, so as to realize the opening and blocking of the pressure relief port 20. In case of temporary failure, the plate can also be manually unsealed by other means. In the later stage, the temporary heating function of the ladle is cooperated to carry out automatic pressure relief, and the function is more abundant.
[0022] A stopper 22 is provided at the rear end of the pressure discharge port 20. The front end surface of the stopper 22 has a slope, which extends to the position bordering the cover body 10, and the slope is not higher than 40°, in order to take into account both the discharge and guidance of hot air.
[0023] The top of the cover 10 is also provided with three lifting ears 30, which are arranged in a triangular shape, one at the center of the front end and two symmetrically arranged at the rear end. The lifting ears 30 are welded from four L-shaped frames, and the corners of the L-shaped frames are chamfered. When the hook is hooked, the forces on both sides are evenly distributed, and there is no obvious warping end when the cover 10 is in the lifting state, and the stability is better.
[0024] like Figure 4 As shown, a plurality of V-shaped reinforcements 12 arranged in an array are embedded inside the cover body 10. The V-shaped reinforcements 12 are arranged in different directions to expand the level of the embedded mechanism. Compared with ordinary reinforcements, the top of the V-shaped reinforcement 12 has horizontal warping to both sides. The cover body 10 mechanism formed after casting the metal is more stable from the perspective of internal force or overall structural strength.
[0025] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
