Description

Technical Field

[0001] The invention relates to the technical field of aluminum silicon carbide carbon brick preparation, in particular to an energy-saving aluminum silicon carbide carbon brick pressing device. Background Art

[0002] Aluminum silicon carbide carbon brick is a high-performance refractory material made of alumina, silicon carbide and carbon as the main raw materials, supplemented by binders such as phenolic resin or asphalt, and made by high-pressure molding and low-temperature drying. During the high-pressure molding process of aluminum silicon carbide carbon bricks, a special pressing device for aluminum silicon carbide carbon bricks is required.

[0003] Aluminum silicon carbide carbon bricks are commonly used refractory materials in iron-making blast furnaces. When they are used in specific parts of the blast furnace hearth, in order to achieve close interlocking between the aluminum silicon carbide carbon bricks and prevent molten iron from penetrating, the aluminum silicon carbide carbon bricks are usually made into a right-angled trapezoidal shape so that the aluminum silicon carbide carbon bricks that fit together can fully adapt to the annular side wall of the blast furnace hearth.

[0004] When using the aluminum silicon carbide carbon brick pressing device in the prior art to press aluminum silicon carbide carbon bricks in the shape of a right-angled trapezoid, a variety of raw materials are poured into the bottom mold, and then a hydraulic cylinder is used to drive the pressure head with an inclined bottom to move downward. Since the brick blank is a right-angled trapezoid, the unit area pressure borne by the thicker end and the thinner end of the brick blank in the pressing groove is different. Under the same pressure, the density of the thin end tends to be too high, while the density of the thick end may be insufficient, thereby generating a large density gradient. After subsequent demolding or heat treatment, layered cracks (lamination cracks) will occur due to uneven release of internal stress, causing the strength of the pressed aluminum silicon carbide carbon brick to drop significantly, which cannot meet the use requirements. In addition, since only one aluminum silicon carbide carbon brick can be pressed at a time, the pressing efficiency is low and the energy-saving and environmental protection effects are poor.

[0005] Therefore, an energy-saving aluminum silicon carbide carbon brick pressing device is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving aluminum silicon carbide carbon brick pressing device, which effectively increases the pressed area of ​​the billet by applying pressure to the billet from the top and side wall at the same time, and can produce multiple aluminum silicon carbide carbon bricks in a single pressing process. It solves the problems that when pressing right-angled trapezoidal aluminum silicon carbide carbon bricks, the billet is pressed from the inclined side, causing the aluminum silicon carbide carbon bricks to produce a large density gradient and layer cracking after demolding, and only a single aluminum silicon carbide carbon brick can be pressed at a time, resulting in low pressing efficiency and poor energy-saving and environmental protection effects. It has the advantages of significantly reducing the density gradient of the aluminum silicon carbide carbon bricks after pressing, thereby ensuring the pressing quality of the aluminum silicon carbide carbon bricks, and effectively improving the pressing efficiency and improving the energy-saving and environmental protection effects.

The movable mold and the pressing mold respectively apply pressure to the raw material filled between the reinforcement plates from the top and side walls of the reinforcement plates.

The sliding sleeve is slidably connected to the limit rod, the connecting seat is installed at the center of the sliding sleeve surface, and the side push structure is installed at the center of the bottom surface of the connecting seat. After the side push structure contacts the pressing mold, it continues to move downward and pushes the pressing mold to slide horizontally toward the inner side of the corresponding reinforcement plate. The four upper pressure structures are distributed in a circular array about the side push structure and are installed at the bottom of the connecting seat, and the upper pressure structure fits with the top of the corresponding reinforcement plate when the sliding sleeve moves downward.

[0015] Preferably, the pressing mold includes a side pressing mold, a top block, a vertical groove, a docking block and a positioning groove. The side pressure mold side wall is provided with a placement groove. The side pressure mold slides and fits between the corresponding U-shaped rib and the fitting plate.

[0016] Preferably, the side pressing die is provided with a pressing slope on the side away from the placement groove.

[0017] Preferably, the top of the docking block is flush with the bottom of the vertical groove, positioning blocks adapted to the positioning grooves are installed on both sides of the docking block, and the side walls of the docking block are provided with contact inclined surfaces adapted to the wedge blocks.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the present invention is applied to the production of aluminum silicon carbide carbon bricks with a right-angled trapezoidal cross-section, compared with the traditional pressing device that only presses the blank from one side, the present invention presses the blank from the top and side wall of the blank at the same time, which effectively increases the pressed area of ​​the blank, and the side pressure and top pressure are carried out synchronously, which can be regarded as the blank being subjected to horizontal pressure and vertical pressure at the same time, which can significantly reduce the density gradient of the aluminum silicon carbide carbon brick blank after pressing, thereby ensuring the pressing quality of the aluminum silicon carbide carbon brick, effectively avoiding the subsequent delamination phenomenon of the aluminum silicon carbide carbon brick, and effectively ensuring the strength of the aluminum silicon carbide carbon brick obtained by pressing; in addition, by converting the vertical pressure of the hydraulic cylinder into horizontal pressure and vertical pressure, it is possible to achieve a single simultaneous pressing of multiple aluminum silicon carbide carbon bricks, effectively improving the pressing efficiency, and reducing the hydraulic cylinder reset idle stroke to reduce energy consumption, thereby improving the energy saving and environmental protection effect of the aluminum silicon carbide carbon brick pressing operation.

[0020] 2. By setting the movable mold and the pressing mold, the side push structure in the movable mold cooperates with the side pressure mold and the docking block in the pressing mold to convert part of the vertical pressure of the hydraulic cylinder into horizontal thrust. When the upper pressure structure applies pressure to the billet from the upper side, the side pressure mold applies pressure to the billet from the side under the cooperation of the side push structure and the docking block, which effectively increases the pressure area of ​​the billet. By applying horizontal and vertical pressure at the same time, the pressure force of the billet is along the diagonal direction of the billet, which can significantly reduce the density gradient of the aluminum silicon carbide carbon brick after pressing, thereby avoiding the delamination phenomenon of the aluminum silicon carbide carbon brick after demoulding or heat treatment, and effectively ensuring the pressing quality and strength of the aluminum silicon carbide carbon brick.

[0021] 3. The inner side of the fixed mold is divided into multiple areas by the provided partitions, reinforcement plates and pressing molds, and the side thrust structure and docking block are used to provide lateral thrust for the pressing mold. When pressing aluminum silicon carbide carbon bricks, multiple aluminum silicon carbide carbon bricks can be pressed at the same time, which greatly improves the pressing efficiency of aluminum silicon carbide carbon bricks, thereby effectively improving the energy-saving and environmental protection effects during the pressing process of aluminum silicon carbide carbon bricks.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 , an energy-saving aluminum silicon carbide carbon brick pressing device includes a base 1, a limit rod 2, a top seat 3, and a hydraulic cylinder 4. Limit sleeves are provided at the four corners of the surface of the base 1, and the four limit rods 2 are respectively inserted into the limit sleeves at the four corners of the surface of the base 1. The top seat 3 is installed and fixed between the tops of the four limit rods 2. The hydraulic cylinder 4 is installed through the surface of the top seat 3, and the piston rod of the hydraulic cylinder 4 extends to the bottom of the top seat 3.

The four partitions 7 are respectively installed at the four inner corners of the fixed mold 6. The partition 7 is L-shaped, and the corners are chamfered with arcs. The four reinforcement plates 8 are respectively fitted on the four partitions 7 The edges of the reinforcement plates 8 fit tightly with the corners of the partitions 7, and the reinforcement plates 8 and the partitions 7 support each other to form a stable structure on the inner side of the fixed die 6, which can withstand a large horizontal pressure, and thus can effectively ensure the stability of the aluminum silicon carbide carbon brick during the pressing process; the four pressing dies 9 are respectively slidably connected to the four reinforcement plates 8, and the tension spring 10 is installed between the reinforcement plates 8 and the pressing die 9. During the downward movement of the movable die 5 driven by the hydraulic cylinder 4, the movable die 5 and the pressing die 9 gradually contact each other, and during the contact process between the pressing die 9 and the movable die 5, the movable die 5 and the pressing die 9 move toward the inner side of the corresponding reinforcement plate 8, and the movable die 5 and the pressing die 9 respectively pressurize the raw materials filled between the reinforcement plates 8 from above and on the side walls of the reinforcement plates 8. After the hydraulic cylinder 4 is reset, the pressing die 9 can be reset under the action of the tension spring 10, so that the blank raw material can continue to be put into the pressing space formed by the fixed die 6, the reinforcement plate 8 and the pressing die 9.

[0036] Reference Figure 4As an embodiment of the present invention, specifically, the movable mold 5 includes a sliding sleeve 51, a connecting seat 52, an upper pressure structure 53 and a side push structure 54. The sliding sleeve 51 is slidably connected to the limit rod 2. When the hydraulic cylinder 4 extends and contracts, the sliding sleeve 51 is driven to move along the limit rod 2. The sliding sleeve 51 and the limit rod 2 slide relative to each other. The connecting seat 52 is installed at the center of the surface of the sliding sleeve 51. A through groove is opened at the center of the sliding sleeve 51, and the edge of the through groove is stepped. The top of the connecting seat 52 is flush with the top of the sliding sleeve 51. The hydraulic cylinder 4 drives the sliding sleeve 51 to move together through the connecting seat 52. The side push structure 54 is installed at the center of the bottom surface of the connecting seat 52, and the side push structure 54 is installed at the bottom center of the connecting seat 52. After the pushing structure 54 contacts the pressing die 9, it continues to move downward and pushes the pressing die 9 to slide horizontally toward the inner side of the corresponding reinforcement plate 8. In this process, the side pressure on the blank is completed, and a slope is formed at the end of the blank, so that the side wall of the blank after pressing is in the shape of a right-angled trapezoid. The four upper pressing structures 53 are distributed in a circular array about the side pushing structure 54 and are installed at the bottom of the connecting seat 52. The number of the upper pressing structures 53 is the same as the number of the partitions 7 and the reinforcement plates 8, and the upper pressing structure 53 is in contact with the top of the corresponding reinforcement plate 8 when the sliding sleeve 51 moves downward. When the bottom of the upper pressing structure 53 is in contact with the top of the reinforcement plate 8, the side wall of the upper pressing structure 53 is in contact with the side wall of the partition 7.

[0037] Reference Figure 4 As an embodiment of the present invention, specifically, the upper pressing structure 53 includes a first bottom column 531 and an upper pressing plate 532. The first bottom column 531 is installed at the bottom of the connecting seat 52, and the upper pressing plate 532 is installed at the bottom of the first bottom column 531. The upper pressing plate 532 is made of 42CrMo material and has undergone surface nitriding treatment. When the upper pressing plate 532 moves downward under the action of the hydraulic cylinder 4, the two ends of the upper pressing plate 532 are respectively fitted with the side walls of the two partitions 7, one side of the upper pressing plate 532 is combined with the side wall of the reinforcement plate 8, and the other side is fitted with the inner wall of the fixed mold 6, thereby compacting the blank in the corresponding space formed by the fixed mold 6, the reinforcement plate 8 and the pressing mold 9, and the blank is pressed and shaped.

[0038] Reference Figure 5 As an embodiment of the present invention, specifically, the side pushing structure 54 includes a second bottom column 541, an auxiliary plate 542 and a pushing block 543. The second bottom column 541 is installed at the bottom of the connecting seat 52, and the auxiliary plate 542 is installed at the outer periphery of the second bottom column 541. The auxiliary plate 542 moves downward in accordance with the vertical groove 93 during the downward movement. Through the cooperation of the auxiliary plate 542 and the vertical groove 93, the stability of the aluminum carbide silicon carbon brick during the pressing process can be further improved. The pushing block 543 is installed at the bottom of the second bottom column 541. The pushing block 543 cooperates with the pressing die 9 during the vertical downward movement. When the pushing block 543 continues to move downward after contacting the pressing die 9, it will push the pressing die 9 to move horizontally, so that the pressing die 9 moves horizontally to apply pressure to the end of the blank.

[0039] Reference Figure 6 As an embodiment of the present invention, specifically, the push block 543 includes a cross seat 5431 and a wedge block 5432. The cross seat 5431 is screwed to the bottom of the second base column 541, and four wedge blocks 5432 are respectively installed at the four ends of the cross seat 5431. The wedge blocks 5432 act as "pressing heads" and are used to form an inclined surface at the end of the blank so that the cross-section of the side wall of the blank after pressing is a right-angled trapezoid.

[0040] Reference Figure 7 As an embodiment of the present invention, specifically, a sinking groove 61 is opened at the center position of the fixed mold 6, and the sinking groove 61 is located between the four pressing molds 9. The depth of the sinking groove 61 is consistent with the height of the cross seat 5431. When the cross seat 5431 is fitted into the sinking groove 61, the pressing mold 9 moves to the maximum horizontal displacement.

[0041] Reference Figure 7 As an embodiment of the present invention, specifically, the reinforcing plate 8 includes a U-shaped rib 81 and a bonding plate 82. The U-shaped rib 81 is bonded between the two partitions 7. A groove 811 is provided on one side of the U-shaped ribs 81 close to each other. The size of the groove 811 is larger than the diameter of the tension spring 10. The end of the tension spring 10 extends into the groove 811. The two bonding plates 82 are integrally connected to both sides of the U-shaped rib 81, and the two bonding plates 82 are bonded to the two partitions 7 respectively. The bonding plates 82 are bonded to the partitions 7. When the blank is pressed, the bonded partitions 7 and the bonding plates 82 can withstand the reaction force from the blank, thereby avoiding deformation of the bonding plates 82 and causing the straight edges of the aluminum silicon carbide carbon bricks to be curved after pressing.

[0042] Reference Figure 8 As an embodiment of the present invention, specifically, the pressing die 9 includes a side pressing die 91, a top block 92, a vertical groove 93, a docking block 94 and a positioning groove 95. The side wall of the side pressing die 91 is provided with a placement groove 912. The side pressing die 91 slides and fits between the corresponding U-shaped ribs 81 and the fitting plate 82. The bottom surface of the side pressing die 91 slides and fits with the inner bottom surface of the fixed die 6. The top block 92 is inserted into the top of the side pressing die 91. The groove 811 is adapted to the top block 92. The depth of the groove 811 is greater than the thickness of the top block 92. When the side pressing die 91 reaches the maximum horizontal displacement When the hydraulic cylinder 4 contracts, the tension spring 10 resets the top block 92 by pushing open the top block 92, so that the side pressure mold 91 is reset. The vertical groove 93 and the positioning groove 95 are both opened in the side wall of the side pressure mold 91, and the positioning groove 95 is located on both sides of the vertical groove 93. The bottom of the positioning groove 95 extends into the placement groove 912, and the docking block 94 is installed in the placement groove 912.

[0043] Reference Figure 8 As an embodiment of the present invention, specifically, a pressing slope 911 is provided on the side of the side pressing die 91 away from the placement groove 912, and the slope of the pressing slope 911 is consistent with the slope of the required pressed aluminum silicon carbide carbon brick.

[0044] Reference Figure 8 and Figure 9 As an embodiment of the present invention, specifically, the top of the docking block 94 is flush with the bottom of the vertical groove 93, and positioning blocks 941 adapted to the positioning groove 95 are installed on both sides of the docking block 94. The docking block 94 is conveniently placed in the placement groove 912 through the cooperation of the positioning block 941 and the positioning groove 95. The side wall of the docking block 94 is provided with a contact inclined surface 942 adapted to the wedge block 5432. The docking block 94 can be replaced to select a suitable docking block 94 with a suitable slope contact inclined surface 942. When the docking block 94 and the wedge block 5432 with different slope contact inclined surfaces 942 are replaced, the maximum horizontal displacement value of the side pressure mold 91 also changes accordingly.

[0045] Working principle: the mixed aluminum silicon carbide carbon brick blank is quantitatively placed in the "pressing groove" formed by the fixed mold 6, the bonding plate 82 and the side pressure mold 91, and then the hydraulic cylinder 4 is started. The hydraulic cylinder 4 drives the sliding sleeve 51, the upper pressure structure 53 and the side push structure 54 to move downward together through the connecting seat 52. The downward structure first contacts the pressing mold 9, and continues to move downward after the push block 543 contacts the positioning block 941. Under the cooperation of the push block 543 and the positioning block 941, the pressing mold 9 moves horizontally to the corresponding "pressing groove" side, and the tension spring 10 is in a compressed state, thereby applying pressure to the end of the blank to form an inclined surface at the end of the blank. When the bottom of the upper pressure structure 53 contacts the top of the reinforcing plate 8 directly below, the upper pressure structure 53 applies pressure to the blank from above. At the same time, the side push assembly stops moving downward, and the pressing mold 9 reaches the maximum horizontal displacement, completing the pressing operation of four aluminum silicon carbide carbon bricks at the same time.

[0046] Specifically, during the downward movement of the movable mold 5, the auxiliary plate 542 in the side pushing structure 54 first enters the vertical grooves 93 in the sidewalls of the side pressing mold 91, ensuring smooth downward movement of the side pushing structure 54, and then the push block 543 moves downward and contacts the positioning block 941, the sidewall of the wedge-shaped block 5432 contacts the contact slope 942 of the positioning block 941, and then during the continuous downward movement of the push block 543, through the cooperation of the wedge-shaped block 5432 and the contact slope 942, the cross seat 5431 pushes the side pressing mold 91 to move horizontally through the wedge-shaped block 5432 and the positioning block 941, while the upper pressing structure 53 moves downward synchronously, the upper pressing plate 532 compacts the fluffy blank downward, and when the cross seat 5431 and the wedge-shaped block 5432 fit in the sinking groove 61, the bottom surface of the upper pressing plate 532 fits with the top of the two fitting plates 82 in the corresponding reinforcing plate 8, the blank is simultaneously subjected to horizontal pressure and vertical pressure, thereby avoiding the formation of a large density gradient in the pressed blank, and further ensuring the strength of the aluminum silicon carbide carbon brick;

[0047] After the pressing is completed, the hydraulic cylinder 4 is retracted and reset, the upper pressing plate 532 is first separated from the top of the fitting plate 82, the tension spring 10 is then reset to open the top block 92, and then the side pressing mold 91 is pushed away from the pressed blank.

[0048] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
