Description

Technical Field

[0001] This invention relates to the field of crystallizer drying technology, and in particular to a crystallizer baking and drying apparatus and its usage method. Background Technology

[0002] A crystallizer is a continuous casting equipment that receives molten steel poured from an intermediate ladle and solidifies it into a solid billet shell according to a specified cross-sectional shape. In the remelting electroslag furnace production process in the iron and steel metallurgical industry, the manual disassembly and assembly of the electroslag furnace takes a long time, and the crystallizer is exposed to the air, making it prone to absorbing moisture. During the smelting process, the heating will generate water vapor, causing porosity in the electroslag ingot. A crystallizer baking and drying device is usually used to remove the moisture inside the crystallizer and keep the inside of the crystallizer dry to solve the problem of porosity in the electroslag ingot.

[0003] Currently, hot air blowers or baking electrode tips are commonly used to dry the inside of the crystallizer to ensure its dryness. However, these baking methods cannot evenly transfer heat to the entire crystallizer, resulting in insufficient drying and poor baking effect. Furthermore, the baking process cannot be sustained, and the dried crystallizer is prone to re-dampening, affecting its normal use. Therefore, it is extremely necessary to invent a crystallizer baking and drying device and its usage method to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a crystallizer baking and drying device and its usage method, which solves the problem that the prior art cannot uniformly transfer heat to the entire crystallizer, resulting in insufficient drying of the crystallizer, and achieves the purpose of improving the baking effect of the crystallizer.

[0009] Preferably, the lifting assembly includes a support slider slidably disposed on the support frame and connecting vertical rods fixedly disposed on both sides of the top of the support slider. The movable horizontal plate is fixedly connected to the two connecting vertical rods on both sides of one end. Sliding vertical grooves are provided on both sides inside the support frame. Limiting blocks are fixedly disposed on both sides of the support slider and are slidably connected to the two sliding vertical grooves respectively. A threaded vertical rod is rotatably disposed on the inner side of the support frame through a bearing, and the threaded vertical rod passes through the support slider and is threadedly connected to it.

[0010] Preferably, a transmission belt is provided at the top of the threaded vertical rod via a pulley, a servo motor two is fixedly installed on the side of the support vertical frame away from the movable horizontal plate, a rotating shaft two is fixedly installed on the output shaft of the servo motor two, and the transmission belt passes through the support vertical frame and is connected to the rotating shaft two via a pulley.

[0011] Preferably, the sealing mechanism includes a sealing cover one and a sealing cover two slidably disposed on both sides of the top of the crystallizer body, and a limiting housing fixedly disposed on the side of the crystallizer body away from the supporting vertical frame. Two intersecting L-shaped slide rods are slidably disposed at both ends of the limiting housing, and the sealing cover one is fixedly connected to one of the L-shaped slide rods. A limiting vertical rod fixedly disposed at both ends of the bottom of the sealing cover two is fixedly fixed to the other L-shaped slide rod.

[0012] Preferably, a gear is provided between the two L-shaped slide rods, and movable racks fixed to the two L-shaped slide rods are respectively meshed on both sides of the gear. A movable shaft is fixed at the axis of the gear and rotatably connected to the limiting housing through a bearing. The sealing mechanism also includes a drive assembly disposed inside the limiting housing for driving the movable shaft to rotate.

[0013] Preferably, the drive assembly includes a second gear fixedly disposed at one end of the movable shaft, and a drive rack meshing with the bottom of the second gear, with positioning seats slidably disposed at both ends of the bottom of the drive rack and fixed to the limiting housing.

[0014] Preferably, a cylinder is fixedly installed inside the limiting housing, a movable push rod is fixedly installed on the output shaft of the cylinder, and an L-shaped block fixed to the drive rack is fixedly installed at one end of the movable push rod.

[0015] A method for using a crystallizer baking and drying apparatus includes the following steps:

[0016] S1: After the crystallizer body has finished working, the cylinder is turned on. The output shaft of the cylinder pushes the movable push rod to move. The movable push rod pushes the drive rack to move through the L-shaped block. The two ends of the drive rack slide on the two positioning seats respectively. The drive rack pushes the second gear to rotate. The second gear drives the movable shaft at its center to rotate. The movable shaft drives the first gear at one end to rotate. The first gear drives the movable racks on both sides to move to both ends respectively. The two movable racks drive the L-shaped slide rods on one side to move to both ends respectively. The two L-shaped slide rods drive the sealing cover one and the sealing cover two to move to both ends respectively, opening the crystallizer body;

[0017] S2: Next, start servo motor two. The output end of servo motor two drives the rotating shaft two on it to rotate. The rotating shaft two drives the transmission belt to run through the pulley. The transmission belt drives the threaded vertical rod to rotate through the pulley. At the same time, the threaded vertical rod rotates and drives the support slider to move downward inside the support vertical frame. The support slider drives the connecting vertical rod to move downward. The connecting vertical rod drives the lifting frame to move downward through the movable horizontal plate. The lifting frame and the heater on it are completely inserted into the crystallizer body.

[0018] S3: Then start servo motor one and start the heater at the same time. The heater generates heat in the crystallizer body. The output end of servo motor one drives drive shaft one to rotate. Shaft one drives the worm at one end to rotate. The worm drives the worm wheel meshing with it to rotate. The worm wheel drives the connecting shaft at its center to rotate. The connecting shaft drives the winding reel at one end to rotate. The winding reel winds up the movable steel rope. The movable steel rope rotates on the fixed pulley. The movable steel rope pulls the heater upward.

[0019] S4: When the heater moves to the top of the inner side of the crystallizer, the output end of servo motor one starts to reverse. Through a series of transmissions, it drives the winding reel to reverse, loosening the movable steel rope. The heater moves downward by gravity and moves up and down inside the crystallizer body to more thoroughly dry the water vapor inside the crystallizer body.

[0020] By employing the above technical solution, the present invention provides a crystallizer baking and drying apparatus and its usage method, which, compared with the prior art, has at least the following beneficial effects:

[0021] 1. This invention uses a drying mechanism to bake and dry the interior of the crystallizer body. A lifting assembly extends the lifting frame and its heater into the crystallizer body. A pulling assembly drives the heater to move up and down on the lifting frame, generating heat to remove moisture from the crystallizer body. This facilitates more thorough drying of the moisture inside the crystallizer body, improves the baking and drying effect of the crystallizer, and keeps the inside of the crystallizer completely dry. This helps to solve the problem of porosity in electroslag ingots and avoids the situation in existing technologies where heat cannot be evenly transferred to the entire crystallizer, resulting in insufficient drying of the crystallizer.

[0022] 2. This invention uses a pulling component to drive the heater to move up and down on the lifting frame. The output of servo motor one drives the rotating shaft one to rotate, which in turn drives the worm gear and worm wheel to rotate, thereby driving the connecting shaft and the winding reel to rotate, winding up the movable steel rope and driving the heater to move upward. When the heater moves to the top of the inner side of the crystallizer, the output of servo motor one reverses, and the heater moves downward by gravity, thus driving the heater to move up and down stably, so as to more fully dry the water vapor in the crystallizer body.

[0023] 3. This invention uses a lifting assembly to drive the lifting frame and its heater in the vertical direction. When moisture needs to be removed from the inside of the crystallizer body, the crystallizer body is opened, and the second servo motor is started, which drives the second rotating shaft to rotate. The second rotating shaft drives the threaded vertical rod to rotate through the transmission belt, thereby driving the support slider to move downward on the support vertical frame. The support slider drives the lifting frame to move downward through the connecting vertical rod and the movable horizontal plate. Then, the heater bakes the inside of the crystallizer body. The operation is convenient, and the lifting frame is more stable when it moves up and down, making it easy to use.

[0024] 4. This invention seals the crystallizer body by setting a sealing mechanism. The drive assembly drives the movable shaft and gear one to rotate. Gear one drives the movable racks on both sides to move towards the center. The two movable racks drive the L-shaped slide rods on one side to move towards the center, thereby driving sealing cover one and sealing cover two to move towards the center, sealing the crystallizer body. This makes it easier to open and close the crystallizer body, improves the sealing performance of the crystallizer body, and facilitates its use. Attached Figure Description

[0042] The drying mechanism 3 includes a lifting frame 31 located inside the crystallizer body 1 and a movable horizontal plate 32 located on the top of the lifting frame 31. A heater 33 is slidably mounted on the lifting frame 31. The heater 33 is common knowledge to those skilled in the art, and its internal structure will not be described in detail in this solution. Limiting sliders 34 are fixedly mounted at the four corners of the heater 33. Limiting vertical grooves 35 are opened at the four corners of the inner side of the lifting frame 31 and are slidably connected to the limiting sliders 34. When the heater 33 moves, the heater 33 drives the limiting sliders 34 to slide inside the limiting vertical grooves 35, which helps the limiting sliders 34 to move more stably. Connecting plates 36 fixed to the movable horizontal plate 32 are respectively fixed at both ends of the top of the lifting frame 31. A pulling component 37 for driving the heater 33 to move upward is mounted on the movable horizontal plate 32. A lifting component 38 for driving the movable horizontal plate 32 to move vertically is mounted on the supporting vertical frame 2.

[0043] The drying mechanism 3 is used to bake and dry the inside of the crystallizer body 1. The lifting frame 31 and the heater 33 on it are extended into the crystallizer body 1 by the lifting component 38. The heater 33 is driven to move up and down on the lifting frame 31 by the pulling component 37. The heater 33 generates heat to remove the water vapor in the crystallizer body 1, which helps to improve the baking and drying effect of the crystallizer and keep the inside of the crystallizer completely dry to help solve the problem of porosity of electroslag ingots.

[0044] The pulling assembly 37 includes a movable steel rope 371 fixedly mounted on the top of the heater 33, with the top of the movable steel rope 371 passing through and slidably connected to the movable horizontal plate 32, and a fixed pulley 372 fixedly mounted on the top of the movable horizontal plate 32 and tactilely connected to the movable steel rope 371. A take-up reel 373 fixedly connected to one end of the movable steel rope 371 is provided on one side of the fixed pulley 372. A limiting seat 374 fixed to the movable horizontal plate 32 is rotatably mounted on the take-up reel 373. A servo motor 375 is fixedly mounted on one top end of the movable horizontal plate 32. A rotating shaft 376 is fixedly mounted on the output shaft of the servo motor 375. A worm gear 377 is fixedly mounted on one end of the rotating shaft 376. A worm wheel 378 is meshed and driven on one side of the worm gear 377. A connecting shaft 379 is fixedly mounted on one end of the take-up reel 373, with one end of the connecting shaft 379 passing through the limiting seat 374 and fixedly connected to the worm wheel 378.

[0045] The specific implementation process is as follows: When drying the crystallizer body 1, the servo motor 375 is started simultaneously with the heater 33. The heater 33 generates heat inside the crystallizer body 1. The output end of the servo motor 375 drives the drive shaft 376 to rotate. The shaft 376 drives the worm gear 377 at one end to rotate. The worm gear 377 drives the worm wheel 378 meshing with it to rotate. The worm wheel 378 drives the connecting shaft 379 at its axis to rotate. The connecting shaft 379 drives the winding reel 373 at one end to rotate. When rotation occurs, the take-up reel 373 winds up the movable steel rope 371, which rotates on the fixed pulley 372. The movable steel rope 371 pulls the heater 33 upward. When the heater 33 moves to the top of the inner side of the crystallizer, the output end of the servo motor 375 starts to reverse. Through a series of transmission belts 386, the take-up reel 373 reverses, loosening the movable steel rope 371. The heater 33 moves downward by gravity. The heater 33 moves up and down inside the crystallizer body 1, which dries the water vapor inside the crystallizer body 1 more thoroughly.

The method of using a crystallizer baking drying apparatus of claim 5, wherein, Includes the following steps: S1: After the crystallizer body (1) has finished working, the cylinder (494) is turned on. The output shaft of the cylinder (494) pushes the movable push rod to move. The movable push rod pushes the drive rack (492) to move through the L-shaped block (495). The two ends of the drive rack (492) slide on the two positioning seats (493) respectively. The drive rack (492) pushes the gear two (491) to rotate. The gear two (491) drives the movable shaft (48) at its axis to rotate. The movable shaft (48) drives the gear one (46) at one end to rotate. The gear one (46) drives the movable racks (47) on both sides to move to both ends respectively. The two movable racks (47) drive the L-shaped slide rod (44) on one side to move to both ends respectively. The two L-shaped slide rods (44) drive the sealing cover one (41) and the sealing cover two (42) to move to both ends respectively, opening the crystallizer body (1). S2: Then start the servo motor 2 (387). The output end of the servo motor 2 (387) drives the rotating shaft 2 (388) on it to rotate. The rotating shaft 2 (388) drives the transmission belt (386) to run through the pulley. The transmission belt (386) drives the threaded vertical rod (385) to rotate through the pulley. While the threaded vertical rod (385) rotates, it drives the support slider (381) to move downward inside the support frame (2). The support slider (381) drives the connecting vertical rod (382) to move downward. The connecting vertical rod (382) drives the lifting frame (31) to move downward through the movable horizontal plate (32). The lifting frame (31) and the heater (33) on it are completely inserted into the crystallizer body (1). S3: Then start the servo motor (375) and start the heater (33) at the same time. The heater (33) generates heat in the crystallizer body (1). The output end of the servo motor (375) drives the rotating shaft (376) to rotate. The rotating shaft (376) drives the worm (377) at one end to rotate. The worm (377) drives the worm wheel (378) meshing with it to rotate. The worm wheel (378) drives the connecting shaft (379) at its axis to rotate. The connecting shaft (379) drives the winding reel (373) at one end to rotate. The winding reel (373) winds up the movable steel rope (371). The movable steel rope (371) rotates on the fixed pulley (372). The movable steel rope (371) pulls the heater (33) upward. S4: When the heater (33) moves to the top of the inner side of the crystallizer, the output end of the servo motor (375) starts to reverse. Through a series of transmissions, the winding reel (373) reverses, loosening the movable steel rope (371). The heater (33) moves downward by gravity. The heater (33) moves up and down inside the crystallizer body (1) to more thoroughly dry the water vapor inside the crystallizer body (1).
