The refractory fiber integral module can be produced by a fully automated continuous production line, eliminating the complicated module folding and extrusion process, improving the working environment of workers and improving the level of automation. Compared with traditional modules, the fiber structure inside the integral module is complete, easy to cut and modify on site, and can form a high-strength integral module after calcination. The module surface has better wear resistance and airflow erosion resistance, and also has excellent durability. In short, the integral module has excellent overall performance and high temperature performance, and is the development trend of refractory fiber modules.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Figure 1 is a structural diagram of a testing device for the anchoring strength of a refractory fiber integral module provided in an embodiment of the present application. As shown in Figure 1, the testing device for the anchoring strength of a refractory fiber integral module includes: a tensile test fixture 1, a tensile testing machine, a test module 2, a protective sheet 3 and a strapping tape 4; protective sheets 3 are respectively provided on both sides of the test module 2, and the strapping tape 4 is bundled around the test module 2 and the protective sheet 3 to clamp the test module 2 between the protective sheets 3 on both sides, and the test module 2 is in an extruded state, two sets of tensile test fixtures 1 are respectively anchored at both ends of the test module 2, and the tensile testing machine is respectively connected to the two sets of tensile test fixtures 1.

The anchoring strength of the test module 2 is tested by pulling the two sets of tensile test fixtures 1 apart by the tensile testing machine, which can be used to guide the optimization of production technology and provide data support for judging the installation firmness of the module; in addition, the test module 2 is extruded to the designed installation extrusion size by using the protective sheet 3 and the strapping tape 4, which can simulate the extrusion state of the test module 2 during use, thereby improving the accuracy of the anchoring strength detection of the test module 2.

[0038] Based on the above embodiments, Figure 2 is a structural diagram of a tensile test fixture provided by an embodiment of the present application. As shown in Figure 2, the tensile test fixture 1 of the embodiment of the present application includes a screw 101, a connecting rod 102, an anchor assembly 103 and a through-rib 104. The connecting rod 102 is connected to the middle part of the screw 101, and the connecting rod 102 is provided with a positioning hole 1021. The positioning hole 1021 is used to connect to the tensile testing machine through a positioning pin. Two groups of anchor assemblies 103 are respectively connected to the two ends of the screw 101, and the two ends of the through-rib 104 are respectively detachably connected to the anchor assemblies 103 connected to the two ends of the screw 101. Both ends of the test module 2 are provided with through-rib holes 201, and the through-rib holes 201 are used for allowing the through-rib 104 to pass through from one side of the test module 2 to the other side of the test module 2.

[0039] The connecting rod 102 in the embodiment of the present application can be welded to the middle part of the screw rod 101. There is no limitation on the specific way in which the through-rib 104 and the anchor assembly 103 can be detachably connected, and can be connected by threading or plugging, etc. Both ends of the test module 2 are provided with through-rib holes 201, and the aperture of the through-rib holes 201 is the same as the outer diameter of the through-rib 104. The tensile test fixture 1 is anchored at both ends of the test module by matching the through-rib holes 201 with the through-rib 104, which can be easily installed and disassembled. In addition, the embodiment of the present application does not limit the number of through-ribs 104 on each group of tensile test fixtures 1, and can be set as needed.

[0040] Based on the above embodiments, the anchor assembly 103 of the embodiment of the present application includes a connecting plate 1031 and an anchor 1032, one end of the connecting plate 1031 is connected to the anchor 1032, and the other end of the connecting plate 1031 is provided with a through hole, the connecting plate 1031 is sleeved on the screw 101 through the through hole and can slide along the screw 101, and the two ends of the screw 101 are respectively provided with a spacing adjuster 105, and the spacing adjuster 105 is used to adjust the distance between the two anchors 1032.

[0041] The embodiment of the present application does not limit the structure of the spacing adjuster 105. For example, the spacing adjuster 105 can be a limit block arranged on the outside of the connecting plate 1031. The limit block is adjustable on the screw rod 101. By changing the distance between the limit blocks at both ends of the screw rod 101, the maximum distance between the two anchors 1032 can be changed. Since the anchor assembly 103 can slide along the screw rod 101, the distance between the two anchors 1032 can be adjusted according to the length of the rib hole 201. The distance between the two anchors 1032 can be adjusted to be consistent with the length of the rib hole 201. When the rib 104 passes through the rib hole 201, the two anchors 1032 just abut against the two sides of the test module 2, thereby preventing the test module 2 from sliding on the rib 104.

[0042] Based on the above embodiment, the spacing adjuster 105 of the embodiment of the present application includes a first nut 1051 and a second nut 1052 connected to the screw rod 101 by threads, and the connecting plate 1031 is sandwiched between the first nut 1051 and the second nut 1052. As shown in FIG2, the connecting plate 1031 can be locked at the set position of the screw rod 101 by adjusting the positions of the first nut 1051 and the second nut 1052 on the screw rod 101. The provision of the first nut 1051 and the second nut 1052 makes it more convenient to adjust the distance between the two anchors 1032.

[0043] Based on the above embodiments, each set of tensile test fixtures 1 in the embodiments of the present application has two through-ribs 104, the anchor 1032 is a U-shaped connector, the bottom of the U-shaped connector is connected to the connecting plate 1031, and both ends of the U-shaped connector are bent to form hooks. The two ends of each through-rib 104 respectively pass through the hooks of the two U-shaped connectors, and the two through-ribs 104 are arranged parallel to each other, and two through-rib holes 201 are provided at both ends of the test module 2.

[0044] Since each set of tensile test fixture 1 is provided with two through-ribs 104, that is, each end of the test module 2 is anchored with two through-ribs 104, the connection firmness between the tensile test fixture 1 and the test module 2 can be provided. The connection mode in which both ends of the through-rib 104 are passed through the hooks of the two U-shaped connectors is convenient for installation and disassembly. Among them, the distance between the two through-ribs 104 of each set of tensile test fixture 1 is the same as the distance between the two through-rib holes 201 at each end of the test module 2.

[0045] Based on the above embodiments, Figure 3 is a structural diagram of a test module provided in an embodiment of the present application, Figure 4 is a schematic diagram of a cotton blank provided in an embodiment of the present application, and Figure 5 is a schematic diagram of a protective sheet provided in an embodiment of the present application. As shown in Figures 3 to 5, the test module 2 is assembled from multiple cotton blanks 202, and the multiple cotton blanks 202 are clamped between two protective sheets 3. Recesses 301 are provided at the edges of both ends of the protective sheets 3, and the rib holes 201 pass through the multiple cotton blanks 202 in sequence and are connected to the recesses 301 of the protective sheets 3 on both sides.

[0046] As shown in FIG3 , the test module 2 is assembled from two cotton blanks 202, one protective sheet 3 is attached to the outside of one cotton blank 202, and the other protective sheet 3 is attached to the outside of the other cotton blank 202, and the two protective sheets 3 sandwich the two cotton blanks 202. Considering that two rib holes 201 are provided at each end of the test module 2, two notches 301 are provided at the edge of each end of the protective sheet 3, and the opening of the notch 301 faces the force direction of the rib 104. The reason for providing the notch 301 on the edge of the protective sheet 3 is that when the rib 104 passes through a plurality of cotton blanks 202 in sequence through the rib holes 201, and the two ends of the rib 104 pass through the notches 301 of the protective sheets 3 on both sides respectively, when the anchor strength test is performed, the protective sheet 3 will not generate resistance to the rib 104, thereby improving the accuracy of the anchor strength test of the test module 2. For example, if a hole is drilled on the protective sheet 3, the protective sheet 3 will produce resistance to the through-rib 104 during the anchor strength test, resulting in an inaccurate anchor strength test of the test module 2. In addition, the opening position of the test module 2 corresponds to the notch 301 on the protective sheet 3, which can also ensure that the protective sheet 3 can effectively maintain the extruded state of the module.

[0047] Based on the above embodiments, the rib hole 201 of the embodiment of the present application is parallel to the end face of the test module 2, and the vertical distance between the end face close to the rib hole 201 and the center of the rib hole 201 is the same as the vertical distance between the rib and the cold surface of the module during actual use.

[0048] As shown in FIG4 , the two ends of the test module 2 refer to the top surface and the bottom surface. Two rib holes 201 are provided at one end close to the top surface of the test module 2, which are denoted as K1 and K1´, and two rib holes 201 are provided at one end close to the bottom surface of the test module 2, which are denoted as K2 and K2´. The vertical distance between the K1 rib hole and the top surface, the vertical distance between the K1´ rib hole and the top surface, the vertical distance between the K2 rib hole and the bottom surface, and the vertical distance L between the K2´ rib hole and the bottom surface are the same, and the vertical distance L is the same as the vertical distance between the rib and the cold surface of the module during actual use. The purpose is to simulate the state and installation position of the module installed in the kiln to the maximum extent, so as to improve the accuracy of the anchor strength detection of the test module 2 and provide reliable data support for judging the installation firmness of the module. Among them, the cold surface of the module refers to the side with lower temperature close to the furnace wall.

[0049] Based on the above embodiment, as shown in Figure 5, the length of the recess 301 in the embodiment of the present application is the vertical distance L+m, and the width of the recess 301 is the hole diameter D+n of the rib hole 201; wherein, m is 10 mm to 30 mm; n is 5 mm to 20 mm; the vertical distance L is 20 mm to 100 mm, and the dimensional deviation is controlled within ±2 mm; as shown in Figure 4, the hole diameters of the four rib holes 201 are the same, the hole diameter D is the same as the outer diameter of the rib 104, and the D deviation is controlled within ±2 mm.

[0050] FIG6 is a flow chart of a method for testing the anchorage strength of a refractory fiber integral module provided in an embodiment of the present application.

[0052] S11: Record the tensile force data detected by the tensile testing machine, and draw a tensile force variation curve based on the tensile force data.

[0053] S12: Determine the anchoring strength of the test module according to the tension variation curve.

[0054] Before the two sets of tensile test fixtures are respectively anchored at the two ends of the test module and the tensile testing machine is respectively connected to the two sets of tensile test fixtures, it also includes: obtaining the water-cutting drawings and inputting the water-cutting drawings into the water-cutting equipment; using the water-cutting equipment to cut and drill the cotton blank according to the water-cutting drawings. The accuracy of the module size, drilling position and aperture size is guaranteed, and the accuracy of the test results is guaranteed. The anchoring strength of the test module is determined according to the tensile change curve. Specifically, the tensile value corresponding to the critical point where the tensile data on the tensile change curve drops can be used as a reference value reflecting the anchoring strength.

[0055] The present application provides a method for testing the anchoring strength of a refractory fiber integral module, which is applied to the above-mentioned testing device for the anchoring strength of a refractory fiber integral module, including: after two sets of tensile test fixtures are respectively anchored at the two ends of the test module, and the tensile test machine is respectively connected to the two sets of clamps for the tensile test fixtures, the tensile test machine is controlled to separate the two sets of tensile test fixtures; the tensile data detected by the tensile test machine is recorded, and a tensile change curve is obtained according to the tensile data; the anchoring strength of the test module is determined according to the tensile change curve. This method is used to test the anchoring strength of the test module, which provides a basis for determining the optimal production technology and provides data support for judging the installation firmness of the module.

[0056] In order to better understand the present application, the following example introduces a test method for the anchoring strength of a refractory fiber integral module.

[0057] A series of tests were conducted to investigate the effect of a certain production process parameter on the anchoring strength of the overall module. During the series of tests, except for the test parameter, all other parameters remained unchanged. The test parameters were adjusted to different values, numbered as: Test 1 to 5, indicating that there were 5 kinds of cotton blanks with different production process parameters.

[0058] In each test, an integral module blank with a thickness of 155 mm to 165 mm was prepared for module cutting. After each process test, 6 cotton blanks with a length of 300 mm and a width of 300 mm were cut, and two rib holes were drilled on both sides of the insulation thickness direction of the cotton blank. The designed hole diameter was 12 mm, and the actual hole diameter after cutting was 11.5 mm to 12.5 mm. The vertical distance between the designed hole and the edge of the module was 40 mm, and the actual vertical distance was 39.5 mm to 40.5 mm.

[0059] Two cotton blanks are combined into an integral module, and three module test samples are prepared by extruding a protective sheet and a strapping tape for the anchor strength test. The notch length of the protective sheet is 60mm and the notch width is 30mm. The final prepared module has a cutting length of 300mm, an extrusion width of 300mm, and an insulation thickness of 300mm.

[0060] Two sets of tensile test fixtures were used, one end was connected to the tensile test machine through the positioning hole, and the other end was connected to the module and the anchor on the fixture through a 12mm diameter rib. After the connection was completed, the tensile test was started, and the anchor strength data of the prepared integral module samples from Tests 1 to 5 were measured, as shown in Table 1. According to the test results of the anchor strength, it was finally determined that the production process parameters corresponding to Test 4 were the optimal parameters, and the product produced by this process was nearly 30 times its own weight, which can ensure that the module does not fall off. It provides guidance for production process optimization and practical application.
