Description

Technical Field

[0001] This invention relates to the field of magnesia-carbon brick forming equipment technology, specifically to a magnesia-carbon brick forming equipment and method for preventing longitudinal cracking of steel ladle walls. Background Technology

[0002] Magnesia-carbon bricks are non-burning composite refractory materials made from high-melting-point alkaline oxide magnesium oxide (melting point 2800°C) and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and bonded with carbonaceous binders. Magnesia-carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladles. In order to prevent cracking of the brick blank during the extrusion molding of magnesia-carbon bricks, the hydraulic equipment usually moves the mold up and down after the material in the mold cavity is initially extruded by the extrusion equipment. This is to vent the extruded brick blank and prevent cracks from appearing. Since the material has already formed a brick blank in the mold cavity and the brick blank has already filled the mold cavity during the initial extrusion of the material by the hydraulic equipment, when the mold slides up and down on the surface of the brick blank to vent the air, the up and down sliding of the mold can easily cause sliding friction between the inner wall of the mold cavity and the surface of the brick blank. This can easily cause scratches on the surface of the brick blank and tearing or breakage during subsequent extrusion and demolding, affecting the molding quality and efficiency of the brick blank. Summary of the Invention

The output ends of the two hydraulic rods are fixedly connected to a mold frame, which is slidably connected to the outer wall of the main body.

[0009] Furthermore, several rectangular frames are installed inside the mold frame; The movable component includes four movable plates that are slidably connected inside the rectangular frame. An elastic plate is fixedly connected to the side of the movable plate near the rectangular frame, and two right-angled strips are fixedly connected to the side of the elastic plate near the movable plate. Two fixing strips are fixedly connected to the side of the movable plate near the elastic plate, and the side wall of the fixing strips has a notch.

[0010] Furthermore, the actuating component includes two spring plates slidably connected to the side wall of the movable plate near the elastic plate, with the elastic ends of the spring plates fixedly connected to the side wall of the movable plate; A fixing plate is fixedly connected to the side wall of the spring plate; An elastic ring is provided between the two spring plates, and a telescopic rod is fixedly connected to the side wall of the elastic ring. The top of the telescopic rod is slidably connected to the top inner wall of the inclined groove.

[0011] Furthermore, a return spring is fixedly connected to the outer surface of the telescopic rod, and the end of the return spring away from the telescopic rod is fixedly connected to the side wall of the inclined groove. The top inner wall of the inclined groove is fixedly connected with four spring support plates; The deformation assembly includes a second elastic ring rotatably connected to the top of the elastic ring. Two protruding rods are fixedly connected to the side of the second elastic ring near the elastic ring. A right-angle block is provided at the end of the protruding rod away from the second elastic ring. Two right-angled blocks are fixedly connected to the side wall of the elastic ring.

[0012] Furthermore, four right-angle frames are fixedly connected to the top inner wall of the inclined groove, and three conical holes are opened on the side wall of the right-angle frames; The active component includes a right-angle plate that is slidably connected inside the right-angle frame, and a tension spring that is fixedly connected to the top of the right-angle plate.

A right-angle block 2 is fixedly connected to the end of the horizontal plate away from the right-angle plate. A wave plate slides between the two right-angled frames.

[0013] Furthermore, a method for using a ladle wall anti-longitudinal cracking magnesia-carbon brick forming equipment, the method comprising the following steps: S1: Placing materials: First, place the materials to be formed into brick blanks between the four moving plates. Since the fixing strip is set in the area at the bottom of the four moving plates, when the materials are placed between the four moving plates, the materials will be between the four moving plates and the lower push frame. S2: Extruding Material: Then start the hydraulic press. When the hydraulic press is working, it will drive the upper push frame to slide down through the support frame. When the upper push frame slides down, it will insert between the four moving plates and perform preliminary extrusion on the material. S3: Final Forming: When the upper push frame initially compresses the material, the two hydraulic rods are activated and they drive the mold frame to slide up and down. When the upper push frame slides up and down, it can vent the initially formed brick blank. Then the hydraulic press is started again. When the hydraulic press is working, it will compress and form the material again through the upper push frame.

[0014] The present invention has the following beneficial effects: 1. In this invention, when the mold frame slides downward and the elastic plate slides into the area of ​​the inclined groove, the elastic plate will reset and press the spring support plate on the inner wall of the top of the inclined groove as the mold frame continues to slide downward. At this time, the spring support plate will be compressed and push the moving plate downward through the elastic plate as the mold frame continues to slide downward. At this time, the moving plate will cause the elastic plate to slide backward relative to the mold frame. At the same time, the friction between the moving plate and the brick blank will be reduced, thereby reducing the scratches caused by the mold frame to the surface of the brick blank during the venting process and the tearing and breakage during subsequent extrusion and demolding, thus improving the molding quality and efficiency of subsequent brick blank forming.

[0015] 2. The present invention, by deforming the elastic ring and locking it at the notch on the two fixed strips, can reduce the situation where the surface of the brick blank is pushed and dented when the moving plate and the elastic plate slide and separate from the inclined groove, due to the elastic plate pushing the side wall of the moving plate. This causes the moving plate to exhaust air on the surface of the brick blank and then slide back to its original position. In this way, the integrity of the brick blank surface forming can be further improved while improving the stability of the moving plate when exhausting air and when the material is squeezed.

[0016] 3. This invention, by slowing down the reset of the elastic ring and the second elastic ring, can reduce the situation where the brick blank collapses due to excessive pushing caused by the excessive reset speed of the moving plate under the elastic reset of the elastic plate when the upper push frame separates from the mold frame. This ensures that the brick blank can be stably demolded while improving the integrity of the brick blank demolding, thereby further improving the demolding efficiency during brick blank forming and demolding.

[0017] 4. In this invention, when the corrugated plate on the side wall of the moving plate is reset, the reset corrugated plate will reset the pushed moving plate, thereby ensuring that the moving plate can be reset synchronously after the brick blank is demolded, and ensuring that the right angle plate can be in the initial state after reset. This can improve the continuity of the moving plate in the subsequent forming of the brick blank and the synchronicity of the moving plate reset, thereby ensuring the forming efficiency of continuous forming of materials.

The sliding assembly 12 includes two hydraulic rods 121 bolted to the outer walls of the left and right sides of the main body 1.

[0028] Several rectangular frames 201 are installed inside the mold frame 122; The movable component 21 includes four movable plates 211 that are slidably connected inside the rectangular frame 201. An elastic plate 212 is fixedly connected to the side of the movable plate 211 near the rectangular frame 201.

Two fixing strips 213 are fixedly connected to the side of the movable plate 211 near the elastic plate 212. The side wall of the fixing strip 213 has a notch. When the material is squeezed by the upper push frame 112 between the four movable plates 211, the movable plate 211 will slide in the rectangular frame 201 under the pressure and squeeze the elastic plate 212. At this time, the elastic plate 212 will adhere to the movable plate 211 and the inner wall of the rectangular frame 201 under the pressure.

[0029] The pushing component 22 includes two spring plates 221 that are slidably connected to the side wall of the movable plate 211 near the elastic plate 212, and the elastic end of the spring plate 221 is fixedly connected to the side wall of the movable plate 211.

When the elastic ring 231 contracts, the middle part of the elastic ring 231 will slide with a convex shape. At the same time, when the elastic ring 231 contracts and the middle part deforms with a convex shape, the deformation of the elastic ring 231 will squeeze the side wall of the right-angled block 232 through the convex rod at the bottom.

[0031] Four right-angle frames 301 are fixedly connected to the top inner wall of the inclined groove 202, and three tapered holes are opened on the side wall of the right-angle frames 301; The active component 31 includes a right-angle plate 311 that is slidably connected inside the right-angle frame 301.

[0032] A method for using a molding equipment for anti-longitudinal cracking magnesia-carbon bricks for ladle walls, the method comprising the following steps: S1: Placing materials: First, place the materials to be formed into brick blanks between the four moving plates 211. Since the fixing strip 213 is set in the area at the bottom of the four moving plates 211, when the materials are placed between the four moving plates 211, the materials will be between the four moving plates 211 and the lower push frame 113. S2: Extruding material: Then start the hydraulic press 101. When the hydraulic press 101 is working, it will drive the upper push frame 112 to slide down through the support frame 111. When the upper push frame 112 slides down, it will be inserted between the four moving plates 211 and perform preliminary extrusion on the material. S3: Final Forming: When the upper push frame 112 initially extrudes the material, the two hydraulic rods 121 are activated and drive the mold frame 122 to slide up and down. When the upper push frame 112 slides up and down, it can vent the initially formed brick blank. Then the hydraulic press 101 is activated again. When the hydraulic press 101 is working, it will extrude the material again through the upper push frame 112.

[0033] In use, the material to be formed into brick blanks is first placed between the four movable plates 211. Since the fixing strip 213 is located at the bottom of the four movable plates 211, when the material is placed between the four movable plates 211, it will be positioned between the four movable plates 211 and the lower push frame 113. Then, the hydraulic press 101 is started. When the hydraulic press 101 is working, it will drive the upper push frame 112 to slide downwards via the support frame 111. When the upper push frame 112 slides downwards, it will insert itself between the four movable plates 211 and initially compress the material. During extrusion, two hydraulic rods 121 are activated, causing them to slide the mold frame 122 up and down. When the upper push frame 112 slides up and down, it can vent the initially formed brick blank. Then, the hydraulic press 101 is activated again. When the hydraulic press 101 is working, it will extrude the material again through the upper push frame 112. Then, the hydraulic press 101 drives the upper push frame 112 to slide upward. After that, the two hydraulic rods 121 drive the mold frame 122 to slide downward, thereby completing the demolding of the formed brick blank. This completes the molding of magnesia-carbon bricks while preventing longitudinal cracks in the brick blank.

[0034] When the material is squeezed by the upper push frame 112 between the four moving plates 211, the moving plates 211 slide within the rectangular frame 201 under pressure and squeeze the elastic plate 212. At this time, the elastic plate 212 adheres to the moving plates 211 and the inner wall of the rectangular frame 201 under pressure. Then, when the mold frame 122 slides down to vent the brick blank, the moving plates 211 drive the elastic plate 212 to not slide down with the mold frame 122 due to the adhesion between the elastic plate 211 and the brick blank. At the same time, when the mold frame 122 slides down and causes the elastic plate 212 to slide into the area of ​​the inclined groove 202, the elastic plate... 212 will reset and, as the mold frame 122 continues to slide down, it will press the spring support plate on the top inner wall of the inclined groove 202. At this time, the spring support plate will be compressed and, as the mold frame 122 continues to slide down, it will push the moving plate 211 to slide down through the elastic plate 212. At this time, the moving plate 211 will cause the elastic plate 212 to slide backward relative to the mold frame 122. At the same time, the friction between the moving plate 211 and the brick blank will be reduced. This will reduce the scratches caused by the mold frame 122 on the surface of the brick blank during the venting process and reduce the tearing and breakage during subsequent extrusion and demolding, thereby improving the molding quality and efficiency of subsequent brick blank forming.

[0035] When the movable plate 211 slides within the rectangular frame 201 and presses against the elastic plate 212, the elastic plate 212 moves closer to the side wall of the movable plate 211 as it slides and presses against the inclined part of the side wall of the spring plate 221 through the right-angle bar. When the side wall of the spring plate 221 is pressed by the right-angle bar, the sliding of the spring plate 221 will push the end of the elastic ring 223 through the fixed plate 222. When both ends of the elastic ring 223 are pushed by the fixed plate 222, the fixed plate 222 will undergo a contraction deformation and both ends will be stuck. The notches on the two fixing strips 213, through the deformation of the elastic ring 223 and its locking in the notches on the two fixing strips 213, can reduce the situation where the moving plate 211 and the elastic plate 212 slide and separate from the inclined groove 202, and the moving plate 211 pushes the side wall of the moving plate 211, causing the surface of the brick blank to be pushed and dented when the moving plate 211 is vented and then reset and slides. This can further improve the integrity of the brick blank surface forming while improving the stability of the moving plate 211 when venting and the material is squeezed.

[0036] When the two ends of elastic ring 223 are compressed and undergo contraction deformation, the contraction deformation of elastic ring 223 will cause elastic ring 231 to contract synchronously. When elastic ring 231 contracts, the middle part of elastic ring 231 will slide with a convex shape. At the same time, when elastic ring 231 contracts and the middle part undergoes convex deformation, the deformation of elastic ring 231 will compress the side wall of right-angle block 232 through the convex rod at the bottom. At this time, the convex rod will cause elastic ring 231 to rotate upward under the guidance of the inclined surface of right-angle block 232. When elastic ring When the elastic ring 231 rotates upward, the rotation of the elastic ring 231 and the outward deformation of its central part will cause the central part of the rotated elastic ring 231 to hook onto the top area of ​​the protruding structure of the C-shaped frame 312. Then, when the upper push frame 112 separates from the mold frame 122 to demold the brick blank, the moving plate 211 will reset when the upper push frame 112 separates. At this time, the spring plate 221 will reset under the release potential energy of its own spring. When the spring plate 221 resets, it will press against the end of the elastic ring 223 through the inclined part of its side wall. When the push is initiated, elastic rings 223 and 231 will reset. When elastic ring 231 resets, it exerts a downward pull on the C-shaped frame 312. As the C-shaped frame 312 slides downward, it draws in external gas through the right-angle plate 311 and the conical hole at the top. This causes the right-angle plate 311 to slide downward. When the right-angle plate 311 slides downward, external gas enters the right-angle frame 301 through the small diameter of the conical hole, allowing the right-angle plate 311 to slowly move under the inflow of air. The downward sliding of the elastic ring 231 and the elastic ring 223 can slow down the reset speed of the elastic ring 223 and the elastic ring 231. By slowing down the reset of the elastic ring 223 and the elastic ring 231, the situation where the brick blank collapses due to excessive pushing caused by the excessive reset speed of the moving plate 211 under the elastic reset of the elastic plate 212 when the upper push frame 112 separates from the mold frame 122 can be ensured. This ensures that the brick blank can be stably demolded while improving the integrity of the brick blank demolding, thereby further improving the demolding efficiency during brick blank forming and demolding.

[0037] When the right-angle plate 311 slides downwards, it will cause the right-angle block 2 to slide downwards simultaneously. When the right-angle block 2 slides downwards, it will squeeze the side wall of the wave plate 314. Since the middle part of the wave plate 314 is initially in a bent state, when the two ends of the wave plate 314 are squeezed, the middle part of the wave plate 314 will undergo a bending deformation. Then, when the moving plate 211 separates from the brick blank and the mold frame 122 and the brick blank is completely demolded, the right-angle plate 311 will return to its original position under the action of the tension spring, and the right-angle block 2 will no longer squeeze the wave plate 314. At this time, the wave plate 314 will then reset, at which point the wave plate 314 will also reset. When the wave plate 314 on the side wall of the moving plate 211 resets, the reset wave plate 314 will reset the pushed moving plate 211, thereby ensuring that the moving plate 211 can be reset synchronously after the brick blank is demolded, while ensuring that the right angle plate 311 can be in the initial state after reset. This can improve the continuity of the subsequent brick blank forming by the moving plate 211 and the synchronicity of the reset of the moving plate 211, thereby ensuring the forming efficiency of continuous forming of materials.
