Description
Technical Field
[0001] The utility model relates to the technical field of refractory materials, in particular to a reinforced inlaid slide plate with a spiral structure. Background Art
[0002] Slide brick is an important functional refractory material used to control the flow rate of molten steel. It needs to be resistant to heat shock and erosion. Different areas of the slide brick are in different temperature conditions during use. Therefore, in actual production, a composite mosaic method is usually used to manufacture slide bricks.
[0003] The inlaid skateboard has higher safety and longer service life than ordinary skateboards. It mainly includes skateboard mother bricks and inlays inlaid on the skateboard mother bricks. The inlays are usually inlaid in the casting holes and slideway positions of the skateboard. According to different production requirements, the inlays can be designed into inlay rings, inlay plates, inlay tubes and other forms. In terms of materials, inlays are usually made of corrosion-resistant materials such as magnesium, magnesium carbon, zirconia, zirconium carbon, etc., while skateboard mother bricks are usually made of materials with good thermal shock resistance, and the requirements for corrosion resistance are relatively low, and generally the corrosion resistance is not as good as the inlays.
[0004] For inlaid skateboards, the mother bricks of the skateboards are usually pre-formed with grooves, which are inlay grooves for accommodating inlays, and the gaps between the inlays and the inlay grooves are filled with fire clay. During the use of the skateboard, the board surfaces slide against each other, and the friction is very large. However, for inlaid skateboards produced by traditional production methods, due to the shrinkage of fire clay and the pores of fire clay itself, the skateboard is prone to problems such as loosening of the inlay and steel seepage in the fire clay during the sliding process, which affects the use of the skateboard. Utility Model Content
[0005] To this end, the technical problem to be solved by the utility model is to provide a reinforced inlaid skateboard with a spiral structure, and the side facade of the inlay of the skateboard is provided with a threaded groove, so that the contact area between the inlay and the fire clay or the skateboard mother brick is increased, the contact is closer, and the bonding strength and bonding stability of the inlay and the skateboard mother brick are increased, thereby preventing the inlay from loosening when the skateboard slides.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0007] A reinforced inlaid skateboard with a spiral structure comprises a skateboard mother brick and an inlay, wherein an inlay groove for accommodating the inlay is provided around a casting hole in the middle of the skateboard mother brick, and the shape of the inlay matches the inlay groove; a thread groove is provided on the side elevation surface of the inlay opposite to the side wall of the inlay groove, the number of spiral turns of the thread groove is greater than or equal to 2, and the spiral axis of the thread groove is parallel to the axis of the casting hole.
[0008] The reinforced inlaid skateboard with a spiral structure has a pitch of 2-8 mm and a groove depth of 1-5 mm.
[0009] In the reinforced inlaid slide with a spiral structure, the thread angle of the thread groove is 0°-60°. When the parameters of the thread groove are within this range, a sufficiently large friction force can be generated between the thread groove and the object in contact with it, and the increased friction force is conducive to the fixation of the inlay.
[0010] The above-mentioned reinforced inlaid slide plate with a spiral structure, the thread of the thread groove is any one of a rectangular thread, a triangular thread, a trapezoidal thread and a serrated thread.
[0011] The reinforced inlaid slide plate with a spiral structure has a pitch of 3 mm and a groove depth of 3 mm. When the pitch is 3 mm and the groove depth is 3 mm, the number of spiral turns of the spiral groove can reach a more appropriate number, and the inlaid body and the object in contact with it can be fully pressed, which is conducive to improving the anti-molten steel leakage effect of the bonding area between the inlaid body and the slide plate mother brick.
[0012] In the above-mentioned reinforced inlaid slide plate with a spiral structure, the side wall of the inlaid groove is squeezed into the thread groove.
[0013] The reinforced inlaid slide plate with a spiral structure has a fire clay layer between the inlaid body and the side wall of the inlaid groove.
[0014] The above-mentioned reinforced inlaid skateboard with a spiral structure, the thickness of the fire clay layer is 1-6mm.
[0015] In the above reinforced inlaid slide plate with a spiral structure, the thread grooves are continuously distributed in the circumferential direction of the inlaid body. The continuously distributed thread grooves can achieve better sealing and impact protection effects.
[0016] The reinforced inlaid slide plate with a spiral structure, wherein the inlaid body is any one of an inlaid ring, an inlaid plate and an inlaid tube.
[0017] The technical solution of the utility model has achieved the following beneficial technical effects:
[0018] 1. In the traditional production method, the mosaic assembled with fire clay is prone to loosening. The utility model designs a threaded groove on the side wall of the mosaic, so that the side wall of the mosaic becomes an uneven surface, increasing the contact area between the mosaic and the fire clay, so that the fire clay firmly bonds the mother brick of the skateboard and the mosaic together, and forms multiple circles of meshing teeth between the fire clay and the mosaic, which can increase the friction between the side surface of the mosaic and the fire clay, greatly enhancing the overall structural stability of the skateboard.
[0019] 2. The threaded groove in the utility model is arranged around the inlay. When the inlay is in the shape of a circular ring, a circular tube or a circular plate, the inlay can be rotated in the inlay groove during installation, so that the fire mud is more evenly distributed in the threaded groove and better filled into every corner of the gap between the inlay and the inlay groove, thereby reducing the structural weakness of the inlay type slide plate caused by uneven distribution of fire mud.
[0020] 3. The utility model provides an inlaid skateboard that does not require the use of fire clay to fix the inlaid body. The joint between the inlaid body and the skateboard mother brick in this skateboard is threaded and tightly connected, which can effectively prevent molten steel from leaking from the connection. The threaded connection makes the inlaid skateboard have better impact and vibration resistance, and has higher safety and longer service life than ordinary inlaid skateboards.

[0026] The reference numerals in the figure are as follows: 1-slide plate mother brick; 2-inlay; 21-thread groove; 3-fire clay layer. DETAILED DESCRIPTION
[0027] Example 1
[0028] like Figure 1 and Figure 2 As shown, the reinforced inlaid skateboard in this embodiment includes a skateboard mother brick 1 and a plate-shaped inlay 2. An inlay groove for accommodating the inlay 2 is opened around the casting hole in the middle of the skateboard mother brick 1, and the shape of the inlay 2 matches the inlay groove.
[0029] like Figure 3 As shown, there is a fire clay layer 3 between the inlay 2 and the inlay groove. The side elevation of the inlay 2 opposite to the side wall of the inlay groove is provided with a thread groove 21, which is continuously distributed in the circumferential direction of the inlay 2. Figure 4 The spiral axis of the thread groove 21 is parallel to the axis of the casting hole.
[0030] In this embodiment, the thread of the thread groove 21 is a triangular thread with a tooth angle of 60°, the pitch of the thread groove 21 is 3 mm, the groove depth of the thread groove 21 is 3 mm, and the number of spiral turns is 6. The design of the thread groove 21 makes the contact area between the side elevation of the inlay 2 and the fire mud larger, and the fire mud can better bond the inlay 2 and the skateboard mother brick 1 together.
[0031] In some other embodiments, the specific values of the number of spiral turns, groove depth, pitch, thread shape and tooth angle of the thread groove 21 can also be adjusted according to actual needs, but the thread groove 21 should at least circle around the inlay twice.
[0032] In this embodiment, the thread groove 21 is integrally formed with the inlay 2, and the material of the inlay is magnesium oxide. In some other embodiments, the thread groove 21 can also be processed on the side surface of the inlay 2 with a tool after the inlay 2 is completed, and the material of the inlay 2 can also be magnesium carbon, zirconium oxide, zirconium carbon or other corrosion-resistant materials.
[0033] The size of the inlay groove in this embodiment is slightly larger than the inlay 2, and the thickest part of the fire mud layer 3 between the side surface of the inlay 2 and the side wall of the inlay groove is 4mm, and the thinnest part is 1mm. When installing the inlay 2 on the skateboard mother brick 1, first apply fire mud on the side and bottom of the inlay 2, and then put the inlay into the inlay groove so that the fire mud fills the gap between the inlay 2 and the skateboard mother brick 1, and then use special equipment or manual compression, dry naturally for 6-12 hours, and then push the skateboard brick into the drying cave to dry at 150-220℃. After drying, the bonding strength of the fire mud increases significantly, and the inlay 2 and the skateboard mother brick 1 can be firmly fixed together.
[0034] Example 2
[0035] In this embodiment, the structure of the reinforced inlaid slide plate is basically the same as that of the embodiment 1, but the side wall of the inlaid groove is squeezed into the thread groove 21, so that the inlaid body 2 and the slide plate mother brick 1 can be fixed together without the aid of fire mud. Figure 5 shown.
[0036] In this embodiment, since the side wall of the inlay groove is squeezed into the thread groove 21, the inlay 2 needs to be embedded in the skateboard mother brick 1 when the brick blank of the skateboard mother brick is pressed. When the granular blank for making the skateboard mother brick is placed in the metal mold for pressurization, the inlay 2 should be placed together and the position of the inlay 2 should be adjusted. When the brick blank of the skateboard mother brick 1 is pressed, the granular blank will be filled into the gap of the thread groove 21. The pressed brick blank is fired and formed to obtain a reinforced inlaid skateboard.
[0037] In Example 1, the fire clay in the fire clay layer 3 forms a spiral meshing tooth that meshes with the thread groove 21, and firmly fixes the inlay 2 in the inlay groove. When the inlay is in the shape of a ring, a tube or a disk, the inlay can be rotated in the inlay groove during installation, and a part of the fire clay can move in the thread groove 21 and be more evenly distributed between the thread groove 21 and the inlay groove.
[0038] Compared with Example 1, the inlaid skateboard in Example 2 does not use fire clay to fix the inlay, but embeds the inlay into the brick during the production stage of the skateboard mother brick, so that the side wall of the inlay groove of the manufactured skateboard mother brick 1 is squeezed into the thread groove 21, and a thread structure matching it is formed. The thread on the side wall of the inlay groove is pressed and formed with the thread groove 21 as a mold, which makes the thread on the side wall of the inlay groove of the inlaid skateboard in Example 2 and the thread on the side elevation of the inlay body press against each other, which can effectively prevent the formation of a gap between the inlay groove and the inlay, resulting in the loosening of the inlay in the radial direction of the casting hole in the inlay groove during the sliding process of the skateboard, and further causing problems such as steel leakage in the skateboard brick. Relatively speaking, the inlay 2 of the inlaid skateboard in Example 2 is less likely to be removed and replaced.
[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
