Description

Technical Field

[0001] The utility model relates to the technical field of steel ingot casting, in particular to a high-efficiency steel ingot casting structure. Background Art

[0002] Molten steel is poured into a casting mold through a ladle and solidified to form an ingot. After the molten steel is smelted in the steelmaking furnace, it must be cast into an ingot or billet of a certain shape before it can be processed. The process of casting an ingot with a casting mold is referred to as ingot casting. When the ingot is cast, in order to protect the safety of the workers, a new ingot casting structure is generally required. In addition, the mold for casting a large number of ingots is relatively large. The temperature of the casting is too high just after casting. Due to the high temperature in the casting area, the cooling rate is slow, which affects the working efficiency of the device. At the same time, the bottom of the traditional ingot mold is closed. After the ingot is formed, the ingot can only be taken out from the top of the mold. This demoulding is more troublesome and inefficient. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0019] An embodiment of the present application provides a high-efficiency steel ingot casting structure. The high-efficiency steel ingot casting structure can be realized by combining four molds into a unit to form a module, thereby reducing the overall weight of the mold, making it easier to move the module to other areas for cooling, and the vacant casting area can be used for the next casting to improve work efficiency.

[0020] The following is a detailed description of the high-efficiency steel ingot casting structure. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0021] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0022] See also Figure 1-5 In this embodiment, a high-efficiency steel ingot casting structure is provided, comprising: a base 1, four demolding holes 11 distributed in a ring array are opened on the top of the base 1, forming cylinders 12 are respectively provided on the top of the four demolding holes 11, and the forming cylinders 12 are detachably connected to the base 1; a casting assembly, which is arranged on the top of the base 1 and is used to cast molten steel into the four forming cylinders 12; and a demolding assembly, which is arranged on the bottom of the base 1 and is used to unload the formed steel ingot from the forming cylinder 12. Example

[0023] On the basis of Example 1, the pouring assembly includes: a pouring frame 2 provided on the top of the base 1, a pouring port 21 corresponding to the four forming cylinders 12 is opened on the pouring frame 2, the bottom of the four pouring ports 21 are fixedly connected to a funnel 22, the four funnels 22 extend into the forming cylinder 12 respectively, a fixed block 23 fixedly installed at the center of the pouring frame 2, a liquid separation cavity 24 is opened inside the fixed block 23, a liquid injection cylinder 25 is fixedly connected to the top of the fixed block 23, and four equally spaced drainage pipes 26 are fixedly connected to the outside of the fixed block 23. The bottom end of the liquid cylinder 25 is communicated with the liquid separation chamber 24, and one end of the four drainage tubes 26 is communicated with the inside of the liquid separation chamber 24 respectively. The four drainage tubes 26 are all arranged to be inclined toward the casting port 21, and one end of the four drainage tubes 26 away from the fixed block 23 extends to the four casting ports 21, and the lower end of the drainage tube 26 is arranged vertically downward. The bottom ends of the four supporting feet of the casting frame 2 are fixedly connected to the support plate 27, and the bottom of the support plate 27 is fixedly connected to the positioning rod 28. The base 1 is provided with a positioning hole 29 for use with the four positioning rods 28.

[0024] When in use, the pouring frame 2 is installed on the base 1, and the positioning rod 28 at the bottom end of the supporting foot of the pouring frame 2 is inserted into the corresponding positioning hole 29. At this time, the four funnels 22 correspond to the four pouring ports 21 respectively. When the overall casting device is preheated, the four support plates 27 increase the contact area and improve the stability. Then the molten steel is poured into the liquid injection cylinder 25, and the molten steel enters the liquid separation chamber 24 along the liquid injection cylinder 25. The molten steel flows outward along the four drainage pipes 26 and flows into the four pouring ports 21, and then flows into the forming cylinder 12 along the funnel 22 for casting. The downward inclined design of the drainage pipe 26 can avoid molten steel retention, and the vertical design of the lower end can avoid excessive impact force when the molten steel flows out. In this way, four steel ingots can be cast at the same time, thereby improving the casting efficiency. After the casting is completed, the casting frame 2 is removed, and the base 1 can be moved to the cooling area for rapid cooling. Example

[0025] On the basis of Example 1, the demolding assembly includes: a mounting bracket 3 respectively arranged under the four demolding holes 11, the mounting bracket 3 is detachably connected to the base 1, and the four mounting brackets 3 are respectively provided with through holes, and threaded blocks 31 are respectively fixedly installed on the top of the four through holes, the threaded block 31 is internally threadedly connected to a threaded rod 32, the bottom end of the threaded rod 32 passes through the through hole and is fixedly connected to a handwheel 33, and the top of the threaded rod 32 is fixedly connected to a tray 34, the diameter of the demolding hole 11 is larger than the diameter of the internal cavity of the molding cylinder 12, the diameter of the tray 34 fits the demolding hole 11, and a blocking block 35 is fixedly connected to the top of the tray 34, and the diameter of the blocking block 35 fits the internal cavity of the molding cylinder 12.

[0026] After cooling is completed, the hand wheel 33 is turned to drive the threaded rod 32 to rotate and screw with the threaded block 31. Since the threaded block 31 is fixed, the threaded rod 32 will be driven to move when screwing. The threaded rod 32 can be controlled to rise or fall by controlling the rotation direction of the threaded rod 32. When demoulding, the threaded rod 32 is controlled to drive the tray 34 to move downward, and the tray 34 drives the blocking block 35 to move and separate from the bottom end of the formed ingot. The bottom of the ingot is separated from the adhesion surface of the blocking block 35 by screwing until the blocking block 35 is removed from the inside of the forming cylinder 12. Then the mounting frame 3 is removed from the base 1 After it is removed, the molded ingot is pushed downward from the inside of the molding cylinder 12 using a demoulding device provided with an external device or by knocking, so as to demould the molded ingot. When casting the steel ingot, the mounting frame 3 is installed correspondingly on the base 1, and then the hand wheel 33 is turned to drive the threaded rod 32 to move upward, pushing the tray 34 to move upward. Since the diameter of the tray 34 is larger than the diameter inside the molding cylinder 12, the maximum rising range of the tray 34 can be limited. When the tray 34 moves to the top, the blocking block 35 is just pushed into the molding cylinder 12 to complete the installation.
