Description

Technical Field

[0001] This utility model relates to the field of casting device technology, specifically to an automatic casting device for carbon ferrochrome ingots. Background Technology

[0002] Ferroalloy casting is the production process for the vast majority of ferroalloys, which is a pyrometallurgical process. Except for products produced by the aluminothermic process, ferrotungsten reduction, and vacuum solid-state decarburization, the pyrometallurgical process for ferroalloys ultimately yields a liquid ferroalloy. Aside from granulation, casting is the most common method for transforming liquid ferroalloys into solid ferroalloys. The equipment used typically includes ladles, ingot molds, and casting machines.

[0003] The existing Chinese utility model patent with publication number CN203018735U discloses an automatic casting device, including a support frame, a crossbeam fixedly welded to the support frame, a vertical boom fixedly welded to the crossbeam, a casting barrel rotatably mounted at the bottom end of the boom, a hinge seat at the bottom of the casting barrel wall, a mounting base fixedly welded to the support frame, and a downwardly tilting cylinder mounted on the mounting base. The end of the cylinder piston rod is hinged to the hinge seat. This utility model has a simple structure, and the casting barrel can be automatically tilted by the downwardly tilting cylinder, eliminating the need for manual tilting, greatly improving production efficiency and providing a reliable guarantee for safe production.

[0004] Currently, in the steel and other metal smelting industries, casting workpieces often generates smoke and water vapor. Furthermore, with existing casting methods, the smoke easily diffuses to the surroundings, resulting in a poor working environment in the casting area. During casting, water vapor condenses and flows back, affecting the casting quality. Utility Model Content

[0009] As a preferred embodiment of this utility model, the drive motor and the reducer are fixedly connected at their power input ends. The drive motor and the reducer are mounted in a mirror-symmetrical configuration on the left and right sides of the top of the support frame. The connecting ring and the support block are rotatably connected. The reducer can increase the rotational torque of the connecting ring to facilitate the rotation of the ladle.

[0011] As a preferred embodiment of this utility model, the receiving frame is located within the central plate-shaped structure of the support frame, the electric push rods are symmetrically installed on the left and right sides of the inner wall of the support frame, and the receiving plate is movably connected to the support frame through the electric push rods; the receiving frame is capable of receiving molten iron.

[0012] As a preferred embodiment of this utility model, a horizontal tubular structure is provided at the center of the connecting plate, and the exhaust motor is installed inside the tubular structure of the connecting plate through a fixing bracket; the exhaust motor can drive the fan blades to rotate and generate forward airflow.

[0015] Compared with the prior art, this utility model provides an automatic casting device for carbon ferrochrome ingots, which has the following advantages:

[0016] 1. This utility model, through the setting of the exhaust hood, can restrict gas from entering the tubular structure of the connecting plate from the rear end of the exhaust hood. The exhaust motor is installed in the center of the tubular structure of the connecting plate by the fixing bracket. When the exhaust motor starts, it drives the fan blades to rotate and generate forward airflow, which reduces the air pressure inside the tubular structure of the connecting plate. External air will enter the tubular structure of the connecting plate from the rear end of the exhaust hood, thereby driving the flue gas and water vapor generated during casting through the connecting plate into the condenser tube, avoiding the diffusion of flue gas generated during casting and affecting the working environment.

The condenser plate is located inside the condenser tube and is vertically and equidistantly installed on the outside of the circulation tube. The bottom surface of the inner cavity of the condenser tube has an inverted triangular structure, and the drain pipe passes through the center of the bottom end of the condenser tube. The circulating water inside the circulation tube lowers the temperature of the condenser plate on the outside of the circulation tube. Water vapor and flue gas will pass through the space between the condenser plates under the restriction of the condenser tube wall, so that the water vapor will condense into water droplets on the surface of the condenser plate and gather on the bottom surface of the inner cavity of the condenser tube, and be discharged from the drain pipe, thereby preventing the condensate from flowing back and affecting the casting quality.

[0026] Please see Figure 1 - Figure 4 In this embodiment, an automatic casting device for carbon ferrochrome ingots includes: a support frame 1, a drive motor 11 and a reducer 12 fixedly mounted on the upper part of the support frame 1, a support block 13 fixedly mounted on the upper part of the support frame 1, a connecting ring 14 inserted inside the support block 13, a ladle 15 fixedly mounted at the center of the connecting ring 14, a receiving frame 16 fitted on the upper part of the support frame 1, a casting pipe 17 inserted at the center of the receiving frame 16, an exhaust hood 18 fixedly mounted on the front side of the support frame 1, and an electric push rod 19 fixedly mounted inside the support frame 1. A receiving plate 110 is fixedly installed at the front end of the rod 19. A connecting plate 111 is fixedly installed on the front side of the exhaust hood 18. A fixing frame 112 is fixedly installed inside the connecting plate 111. An exhaust motor 113 is fixedly installed at the center of the fixing frame 112. A fan blade 114 is fixedly installed on the outside of the shaft of the exhaust motor 113. A condenser pipe 115 is fixedly installed at the front end of the connecting plate 111. A circulation pipe 116 is inserted inside the condenser pipe 115. A condenser plate 117 is fixedly installed on the outside of the circulation pipe 116. A drain pipe 118 is fixedly installed below the condenser pipe 115.

[0027] The drive motor 11 and the reducer 12 are fixedly connected at their power input ends. The drive motor 11 and the reducer 12 are mirror-symmetrically mounted on the left and right sides of the top of the support frame 1. The connecting ring 14 and the support block 13 are rotatably connected. The left and right ends of the connecting ring 14 are fixedly connected to the output ends of the reducers 12 on the left and right sides of the top of the support frame 1, respectively. The steel ladle 15 is movably mounted on the top of the support frame 1 through the connecting ring 14. The receiving frame 16 is located inside the central plate-like structure of the support frame 1. The electric push rods 19 are symmetrically mounted on the left and right sides of the inner wall of the support frame 1. The receiving plate 1 10 is connected to the support frame 1 by electric push rod 19. A horizontal tubular structure is provided at the center of the connecting plate 111. The exhaust fan motor 113 is installed inside the tubular structure of the connecting plate 111 by fixing frame 112. The rear end of the condenser pipe 115 is fitted with the front end of the tubular structure of the connecting plate 111. The condenser plate 117 is located inside the condenser pipe 115 and is installed vertically at equal intervals on the outside of the circulation pipe 116. The bottom surface of the inner cavity of the condenser pipe 115 is an inverted triangular structure, and the drain pipe 118 passes through the center of the bottom end of the condenser pipe 115.

[0028] Specifically, the drive motor 11 is model SC17, the reducer 12 is model ZQH500, the electric actuator 19 is model NKLA22B, the exhaust motor 113 is model CH-28-0.4KW-1 / 50, the support frame 1 supports the support block 13, raising the position of the ladle 15 so that the casting mold is located below the ladle 15, the support block 13 restricts the position of the ladle 15, and the drive motor 11 drives the reducer 12 to increase the rotation of the connecting ring 14. The torque is adjusted so that the connecting ring 14 can rotate the ladle 15 to pour out the molten iron inside the ladle 15. The molten iron is received by the receiving frame 16, which restricts the flow of the molten iron down through the casting pipe 17 to the mold above the receiving plate 110. The position of the receiving plate 110 is adjusted by the electric push rod 19, thereby adjusting the position of the mold above the receiving plate 110. After casting is completed, the mold can be removed from below the casting pipe 17 for easy removal. The exhaust hood 18 restricts gas from entering the connecting plate 111 from the rear end of the exhaust hood 18. Inside the tubular structure, the exhaust fan 113 is mounted at the center of the connecting plate 111 tubular structure via a fixing bracket 112. When the exhaust fan 113 starts, it drives the fan blades 114 to rotate, generating a forward airflow. This reduces the air pressure inside the connecting plate 111 tubular structure, allowing external air to enter the connecting plate 111 tubular structure from the rear end of the exhaust hood 18. This, in turn, draws the flue gas and water vapor generated during casting through the connecting plate 111 into the condenser tube 115, and then through the circulating water in the circulation pipe 116. The temperature of the condenser plate 117 on the outside of the low circulation pipe 116 causes water vapor and flue gas to pass through the space between the condenser plates 117 under the restriction of the condenser pipe 115 wall. This causes water vapor to condense into water droplets on the surface of the condenser plate 117 and gather at the bottom of the inner cavity of the condenser pipe 115, and be discharged from the drain pipe 118. Flue gas will pass through the condenser pipe 115. The front end of the condenser pipe 115 is provided with a flange structure. After connecting the condenser pipe 115 to the dust removal equipment, the flue gas will enter the dust removal equipment from the end of the condenser pipe 115 for dust removal.

[0029] In use, the exhaust hood 18 restricts gas from entering the tubular structure of the connecting plate 111 from its rear end. The exhaust motor 113 is mounted at the center of the tubular structure of the connecting plate 111 via the mounting bracket 112. When the exhaust motor 113 starts, it drives the fan blades 114 to rotate, generating a forward airflow. This reduces the internal air pressure of the tubular structure of the connecting plate 111, allowing external air to enter the tubular structure of the connecting plate 111 from the rear end of the exhaust hood 18. This, in turn, draws the fumes and moisture generated during casting through the connecting plate 111 into the condenser tube 115, preventing the fumes from spreading and affecting the working environment. The rear end of the condenser tube 115 is connected to the connecting plate 111. The front end of the structure is fitted with a condenser plate 117 located inside the condenser tube 115, and the condenser plate 117 is vertically and equidistantly installed on the outside of the circulation tube 116. The bottom surface of the inner cavity of the condenser tube 115 has an inverted triangular structure, and the drain pipe 118 passes through the center of the bottom end of the condenser tube 115. The circulating water inside the circulation tube 116 lowers the temperature of the condenser plate 117 on the outside of the circulation tube 116. Water vapor and flue gas will pass through the space between the condenser plates 117 under the restriction of the tube wall of the condenser tube 115, so that the water vapor will condense into water droplets on the surface of the condenser plate 117 and gather on the bottom surface of the inner cavity of the condenser tube 115, and be discharged from the drain pipe 118, thereby preventing the condensate from flowing back and affecting the casting quality.
