Description

Technical Field

[0001] This invention relates to a composite sliding plate brick pressing mold and its pressing process, belonging to the field of sliding plate brick production technology. Background Technology

[0002] With the refractory materials market becoming increasingly competitive, there is a global shortage of non-renewable raw materials, and high-grade, high-performance raw materials are in short supply and expensive. Using uniform high-grade raw materials for whole sliding plate bricks puts increasing cost pressure on businesses, making it difficult to maintain good profits and sustainable development.

[0003] Meanwhile, as a functional refractory material used in steelmaking, sliding plate bricks are subject to harsh operating conditions. Therefore, their service life and safety are important evaluation indicators. The molding process is a key step in the production of sliding plate bricks. The density and uniformity of different parts of the sliding plate brick during molding have a significant impact on its performance and application. In traditional brick-pressing molds, especially when producing sliding plate bricks with a lower boss (this type of sliding plate brick is mainly used in sliding gates with a male-female joint), more material needs to be piled up at the lower boss. However, currently, this is done manually, mostly by pressing and piling material by hand. Firstly, the material piling requires manual control, making it difficult to achieve precise control. Secondly, the material is added to the lower boss in stages, and the different stress conditions during addition can lead to inconsistent density. Summary of the Invention

[0004] To overcome the above problems, the present invention provides a composite sliding plate brick pressing mold and its pressing process. The composite sliding plate brick pressing mold has a simple structure and can effectively reduce the manufacturing cost of sliding plate bricks.

[0011] Furthermore, the upper end of the core rod is flush with the upper end of the floating mold frame.

[0012] Furthermore, the upper end of the core rod is inserted into the lower end face of the upper model cover.

[0014] A brick pressing process for a composite sliding plate brick pressing mold, the specific steps of which are as follows:

[0015] Step 1, First Fabric Preparation:

[0016] The floating mold frame is raised; then, the second drive mechanism drives the floating plate to move up until the upper end face of the top tube is flush with the upper end face of the floating mold frame; then, the first drive mechanism drives the floating lower mold to move up, so that the upper end face of the lower mold core is separated from the upper end face of the floating mold frame; finally, ordinary peripheral material is evenly filled into the space formed by the upper end of the lower mold core and the inner circumference of the floating mold frame to complete the first material placement.

[0017] Step 2: Pre-compression;

[0018] The floating mold frame is raised again; then, the second drive mechanism drives the floating plate to move up until the upper end face of the top tube is flush with the upper end face of the floating mold frame; then, the pre-pressing mechanism is driven to move the contour upper mold core above the ordinary outer material, and then the pre-pressing mechanism is driven to press down, the contour upper mold core presses down on the ordinary outer material, and the pre-pressing work is completed; finally, the pre-pressing mechanism is driven to reset.

[0019] Step 3, second layer of fabric;

[0020] The second drive mechanism drives the floating plate to move down, and the jacking pipe to move down, leaving a compensation section between the upper end face of the jacking pipe and the lower end face of the guide cone; then, the floating mold frame is raised again; finally, the composite material is evenly filled above the ordinary outer material to complete the second material placement.

[0021] Step 4: Pressing the sliding block;

[0022] The floating upper mold is driven to move the upper mold cover above the composite material, and then the floating upper mold is driven to press down, and the upper mold cover presses down on the composite material; then the floating plate and the floating lower mold gradually descend under the pressure of the floating upper mold until the floating lower mold presses on the support base; then the floating upper mold applies maximum pressure until the slide block body is pressed and formed.

[0023] Step 5: Demolding;

[0024] The upper floating mold is driven to move upward and reset; then, the second driving mechanism drives the floating plate to move upward, so that the top tube completely pushes the slide block body out of the floating mold frame; then, the floating mold frame and the lower floating mold are driven to reset, waiting for the next pressing operation.

[0025] The present invention has the following beneficial effects:

[0026] 1. The composite sliding brick pressing mold has a simple structure, which can effectively reduce the manufacturing cost of sliding bricks; at the same time, the four-axis linkage method ensures a good secondary material distribution effect.

[0027] 2. The sliding block body only uses high-temperature resistant composite material in the part that comes into contact with molten iron, while the rest of the body uses ordinary outer material, which can effectively reduce the manufacturing cost of the sliding block.

[0028] 3. A four-axis linkage method is adopted, with the first hydraulic cylinder as one axis, the second hydraulic cylinder as one axis, the floating mold frame as one axis, and the upper mold cover as one axis. The four axes are linked during the brick pressing process to achieve a good secondary material distribution effect.

[0029] 4. During the second material feeding process, a compensation section is set up so that when high-temperature resistant composite material is added to the pre-compressed ordinary outer material, even if the two have different densities and stress conditions, the predetermined compression ratio can still be achieved after the subsequent brick pressing process. This improves the density of the composite material in the sliding brick and avoids the problem of insufficient performance of the entire sliding brick due to the poor strength of the composite material.

[0045] According to the above description, the composite sliding plate brick pressing mold includes a floating upper mold 2, a mold box 3, a floating plate 4, and a floating lower mold 5; the floating upper mold 2 is provided with an upper template 21 and an upper mold cover 22, the upper mold cover 22 is mainly used to provide pressure from above to press the sliding plate brick body 1; the mold box 3 includes a floating mold frame 31, a support plate 32, a core rod 33, and a support rod 34, the floating mold frame 31 restricts the outer periphery of the sliding plate brick body 1, while the core rod 33 is used to restrict the inner periphery of the sliding plate brick body 1 (mainly used to restrict the composite material 12 during secondary material distribution); the floating plate 4 is provided with a top tube 41, and a transverse through groove is opened in the middle of the top tube 41. The support plate 32 is slidably fitted in the groove, allowing the mold box 3 to move up and down. In addition, the top tube 41 is also used to restrict the inner circumference of the slide block body 1 (mainly to restrict the ordinary outer material 11 during the first material feeding). The floating lower mold 5 includes a lower template 51, a lower mold base 52, and a lower mold core 53. The lower mold core 53 is mainly used to provide pressure from below to press the slide block body 1. At the same time, the upper end of the lower mold core 53 is provided with a guide cone surface 54 on the outer circumference of the top tube 41 (that is, it is provided corresponding to the lower boss 15 of the slide block body 1).

[0046] Furthermore, the lower end of the upper mold cover 22, the inner periphery of the floating mold frame 31, the upper end face of the lower mold core 53, the inner side of the guide cone surface 54, the upper end face of the top tube 41, and the outer periphery of the core rod 33 together form a cavity for pressing the sliding brick body 1; the sliding brick body 1 includes ordinary outer material 11 and composite material 12; the composite material 12 includes a horizontal brick surface 13 and a vertical hollow brick protrusion 14 fixed at the lower end of the brick surface 13; the ordinary outer material 11 is horizontally arranged and sleeved on the outside of the brick protrusion 14; the portion of the ordinary outer material 11 near the brick protrusion 14 gradually narrows downward to form a lower protrusion 15; the lower end of the lower protrusion 15 is flush with the lower end of the brick protrusion 14.

[0047] As described above, the pressed sliding plate brick body 1 includes ordinary outer material 11 and composite material 12. Since only the upper surface and inner ring of the brick blank come into contact with molten iron during use, and the remaining parts do not require high-temperature resistance, to save costs, only the parts in contact with molten iron can use the high-temperature resistant composite material 12, while the remaining parts can use the ordinary outer material 11.

[0049] Furthermore, a support base 73 is provided below the lower template 51; the support base 73 is located below the jacking pipe 41, and the size of the support base 73 is larger than the outer diameter of the jacking pipe 41; the lower end of the support base 73 is fixed to the ground, and the upper end is attached to the lower end of the lower template 51.

[0050] Furthermore, the upper end of the core rod 33 is flush with the upper end of the floating mold frame 31. The flushness of the upper end of the core rod 33 with the upper end of the floating mold frame 31 is mainly to ensure that during the material laying process, both the ordinary outer material 11 and the composite material 12 are outside the core rod 33, thus ensuring that the hole in the middle of the slide block body 1 is left open.

[0051] Furthermore, the upper end of the core rod 33 is inserted into the lower end face of the upper model cover 22, mainly to further ensure that the hole in the middle of the slide block body 1 is left open.

[0052] Furthermore, the first driving mechanism is a first hydraulic cylinder 71; the second driving mechanism is a second hydraulic cylinder 72; the first hydraulic cylinder 71 is vertically set on the ground, and its upper piston rod is fixed to the lower end of the lower template 51; the floating plate 4 extends through the clearance groove at both ends; the second hydraulic cylinder 72 is vertically set on the ground, and its upper piston rod extends through the lower template 51 and is fixed to the lower end of the floating plate 4.

[0053] A brick pressing process for a composite sliding plate brick pressing mold, the specific steps of which are as follows:

[0054] Step 1, First Fabric Preparation:

[0055] The floating mold frame 31 is raised; then, the second drive mechanism drives the floating plate 4 to move upward until the upper end face of the top tube 41 is flush with the upper end face of the floating mold frame 31; then, the first drive mechanism drives the floating lower mold 5 to move upward, so that the upper end face of the lower mold core 53 is separated from the upper end face of the floating mold frame 31, ensuring space for the first material placement; finally, the ordinary peripheral material 11 is evenly filled into the cavity through the material cart in the space formed by the upper end of the lower mold core 53 and the inner circumference of the floating mold frame 31, completing the first material placement.

[0056] Step 2: Pre-compression;

[0057] The floating mold frame 31 is raised again; then, the second drive mechanism drives the floating plate 4 to move upward until the upper end face of the top tube 41 is flush with the upper end face of the floating mold frame 31; then, the pre-pressing mechanism 6 is driven to move the contour upper mold core 61 above the ordinary peripheral material 11, and then the pre-pressing mechanism 6 is driven to press down, the contour upper mold core 61 presses down on the ordinary peripheral material 11, and the pre-pressing work is completed; finally, the pre-pressing mechanism 6 is driven to reset.

[0058] Step 3, second layer of fabric;

[0059] The second drive mechanism drives the floating plate 4 to move down, and the jacking pipe 41 to move down, leaving a compensation section between the upper end face of the jacking pipe 41 and the lower end face of the guide cone surface 54; then, the floating mold frame 31 is raised again; finally, the composite material 12 is evenly filled above the ordinary peripheral material 11 to complete the second material placement.

[0060] Two materials were used to save costs, resulting in differences in the materials of the composite material 12 and the ordinary outer material 11, thus their compression ratios are also different. After the ordinary outer material 11 has completed one pre-compression, it has reached the predetermined compression ratio. At this point, if the lower end face of the composite material 12 is directly flush with the lower end face of the ordinary outer material 11, then during the pressing process, either the lower end face of the composite material 12 will remain flush with the lower end face of the ordinary outer material 11, causing the brick protrusion 14 to fail to reach the predetermined density and thus not meet the usage requirements; or the brick protrusion 14 will reach the specified density, but due to "shrinkage" during the pressing process, there will be a material shortage at the lower end of the brick protrusion 14, which also fails to meet the usage requirements. Therefore, during the secondary material distribution, a compensation section L needs to be specifically set to address the "shrinkage" of the composite material 12 to prevent insufficient density or material shortage.

[0061] Specifically, the sum of the compression stroke of the compensation section L and the ordinary peripheral material 11 (i.e., the total compression stroke of the brick protrusion 14 in the corresponding composite material 12) should meet the compression ratio requirements of the brick protrusion 14. In actual production, the compensation section L can be initially calculated based on the compression ratio and compression stroke of the ordinary peripheral material 11 and the brick protrusion 14; then, through several trial moldings and fine adjustments, the appropriate compensation section L can be finally determined.

[0062] Step 4: Pressing the sliding block;

[0063] Drive the floating upper mold 2 to move the upper mold cover 22 above the composite material 12, and then drive the floating upper mold 2 to press down, and the upper mold cover 22 presses down on the composite material 12; then the floating plate 4 and the floating lower mold 5 gradually descend under the pressure of the floating upper mold 2 until the floating lower mold 5 presses on the support seat 73; then the floating upper mold 2 applies the maximum pressure until the slide block body 1 is pressed and formed.

[0064] Step 5: Demolding;

[0065] The upper floating mold 2 is driven to move upward and reset; then, the second driving mechanism drives the floating plate 4 to move upward, so that the top tube 41 completely pushes the slide block body 1 out of the floating mold frame 31, and the slide block body 1 can be taken out; then, the floating mold frame 31 and the lower floating mold 5 are driven to reset, waiting for the next pressing operation.

Step 4: Pressing the sliding block; Drive the floating upper mold (2) to move the upper mold cover (22) above the composite material (12), then drive the floating upper mold (2) to press down, and the upper mold cover (22) presses down on the composite material (12); then the floating plate (4) and the floating lower mold (5) gradually descend under the pressure of the floating upper mold (2) until the floating lower mold (5) presses on the support base (73); then the floating upper mold (2) applies the maximum pressure until the slide block body (1) is pressed and formed; Step 5: Demolding; Drive the floating upper mold (2) to move upward and reset; then, the second drive mechanism drives the floating plate (4) to move upward, so that the top tube (41) completely pushes the slide block body (1) out of the floating mold frame (31); then, drive the floating mold frame (31) and the floating lower mold (5) to reset, waiting for the next pressing operation.
