Description

Technical Field

[0001] This utility model relates to the field of thermal shock resistance measurement technology, and more specifically, to a thermal shock resistance measurement device. Background Technology

[0002] The ability of a material to withstand rapid temperature changes without being damaged is called thermal shock resistance. Thermal shock resistance is an important property of inorganic non-metallic materials (glass, ceramics, refractories, etc.). When a material is suddenly heated (or cooled) and expands (or contracts), thermal stress is generated because the deformation of its various parts is mutually restrained. When this thermal stress exceeds the material's ultimate strength, it will crack, peel, or fracture, resulting in failure. Besides being affected by heat transfer conditions, a material's thermal shock resistance mainly depends on its coefficient of thermal expansion, thermal conductivity, fracture toughness, specific heat, and strength, and is also related to its microstructure, shape, and dimensions.

[0003] Currently, there are not many devices specifically designed for thermal shock resistance testing. The traditional method involves placing the sample to be tested in a conventional high-temperature furnace, heating it to the required experimental temperature, manually opening the furnace door, and removing the sample piece by piece from the furnace chamber and placing it into a cooling medium container.

[0004] However, with the furnace door open, the temperature inside the furnace decreases, and the temperature of the sample being tested also decreases. The material handling process also takes time, and the sample absorbs heat when it comes into contact with the fixture, further lowering its temperature. This results in different temperatures for the samples when they enter the cooling medium container, meaning that each sample experiences a different temperature difference, and each operator operates at a different speed. Consequently, the test repeatability is poor, and the accuracy of the test is low. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To address the problem of low accuracy in measuring the thermal shock resistance of materials under temperature changes in existing technologies, this invention provides a thermal shock resistance measurement device.

[0030] Please refer to Figure 1 As shown, the present invention provides a thermal shock resistance measurement device, including a furnace body 10, a heating component 20, a cooling component 30, and a movable component 40. The furnace body 10 has a first cavity 11 and a second cavity 12 spaced apart, which are connected by a through hole 13, which is closable. The heating component 20 is disposed in the first cavity 11 to heat the temperature in the first cavity 11 to a preset temperature. The cooling component 30 is disposed in the second cavity 12 and is used to contain a coolant 31 at a set temperature. The movable component 40 includes a support part 41 for containing a sample 1 to be tested. The support part 41 is disposed in the first cavity 11 and is movably disposed between the first cavity 11 and the second cavity 12, so that after the first cavity 11 is heated to the preset temperature, the support part 41 moves the sample 1 to be tested into the second cavity 12 and into contact with the coolant 31.

[0031] By applying the technical solution of this embodiment, the heating component 20 can be placed in the first cavity 11 to precisely control the preset temperature that the sample 1 needs to withstand during testing. Simultaneously, by placing the cooling component 30 in the second cavity 12, the coolant 31 can be kept at a constant low temperature, thereby enabling accurate measurement of the thermal shock resistance of the sample 1 under rapid temperature changes from high to low. The support component 41 can move rapidly between the first cavity 11 and the second cavity 12, allowing the sample 1 to contact the coolant 31 immediately after reaching the preset temperature in the first cavity 11. This rapid temperature transition can simulate the extreme temperature changes that the sample 1 may encounter in practical applications, improving the accuracy of the test and thus solving the problem of low accuracy in measuring the thermal shock resistance of materials under temperature changes in the prior art. Furthermore, the design of the movable component 40 automates the testing process, reducing direct operator intervention, improving testing efficiency, and lowering safety risks during operation.

[0032] In this embodiment, the sample to be tested, 1, is glass.

[0033] It should be noted that this invention can be used not only in the glass industry, but also for other applicable test materials. Furthermore, depending on the characteristics of the test material, different materials can be selectively designed for the device, and the thermal shock resistance temperature can reach 1600℃ or even higher.

[0034] To control the opening and closing of the through-hole 13, the thermal shock resistance measurement device also includes a heat insulation component 50. At least a portion of the heat insulation component 50 is movably disposed within the first cavity 11 or the second cavity 12 and located at the through-hole 13 for opening or closing the through-hole 13. Thus, the heat insulation component 50 effectively isolates the temperatures of the first cavity 11 and the second cavity 12 during the test, preventing the influence of the low temperature of the second cavity 12 or the high temperature of the first cavity 11 on the temperature of the other cavity when the sample under test 1 has not undergone temperature transition, ensuring the independence and accuracy of the heating and cooling processes. Furthermore, since the heat insulation component 50 can move quickly to open or close the through-hole 13, the sample under test 1 can be rapidly transitioned from a heating environment to a cooling environment. This is particularly important for the response of the test material under extreme temperature changes, enabling the simulation of a more realistic thermal shock environment.

[0035] Specifically, the heat insulation component 50 includes a heat insulation element 51 and a connecting rod 52; the heat insulation element 51 is located at the through hole 13; one end of the connecting rod 52 is connected to the heat insulation element 51, and the other end of the connecting rod 52 extends to the outside of the furnace body 10 and is provided with an operating part 53 for controlling the connecting rod 52 to drive the heat insulation element 51 to move; a first limiting member 54 is provided on the connecting rod 52, and the first limiting member 54 is used to limit contact with the outer wall of the furnace body 10; wherein, the heat insulation element 51 is made of high zirconium material.

[0036] The operator can control the connecting rod 52 via the operating unit 53 to move the heat insulation component 51, precisely opening or closing the through hole 13 to achieve effective isolation or connection between the first cavity 11 and the second cavity 12. The first limiting component 54 makes limiting contact with the outer wall of the furnace body 10, ensuring the precise position of the heat insulation component 51 during movement and preventing temperature leakage due to inaccurate movement causing incomplete sealing of the through hole 13. High zirconium material is selected as the material for the heat insulation component 51 because it has excellent heat insulation performance, effectively preventing heat transfer and ensuring temperature isolation between the first cavity 11 and the second cavity 12 in the closed state, thus improving the accuracy of the test. High zirconium material not only has good heat insulation performance but also high high temperature resistance and corrosion resistance, which can improve the durability of the heat insulation component 51 and the safety of the entire equipment, extending the service life of the equipment. Furthermore, the high thermal resistance of the heat insulation component 51 can significantly reduce heat exchange between the first cavity 11 and the second cavity 12 during the test, reducing heat loss and improving energy utilization efficiency.

[0037] Alternatively, the portion of the connecting rod 52 located within the first cavity 11 may also be made of high zirconium material.

[0038] To enable the support part 41 to move between the first cavity 11 and the second cavity 12, the furnace body 10 is provided with a mounting hole 14 communicating with the first cavity 11. The movable component 40 includes a first movable rod 42 and a second movable rod 43. The first end of the first movable rod 42 extends into the first cavity 11 through the mounting hole 14, and the support part 41 is disposed on the first end of the first movable rod 42. The second movable rod 43 is arranged perpendicular to the first movable rod 42, and the first end of the second movable rod 43 is rotatably connected to the second end of the first movable rod 42. The first movable rod 42 is made of platinum.

[0039] Platinum was chosen as the material for the first movable rod 42, significantly improving the thermal stability and thermal conductivity of the movable component 40. Platinum possesses excellent high-temperature stability, is not easily oxidized or corroded, and can withstand the high-temperature environment within the first cavity 11. Simultaneously, its thermal conductivity ensures uniform temperature distribution on the support portion 41, improving the accuracy and reliability of the test. The vertical arrangement and rotatable connection between the first movable rod 42 and the second movable rod 43 allow the support portion 41 on the first movable rod 42 to move between the first cavity 11 and the second cavity 12 by controlling the movement of the second movable rod 43, thereby allowing precise position adjustment of the sample 1 under test in both directions. This design allows the sample 1 to be quickly and accurately moved into the second cavity 12 after reaching the preset temperature in the first cavity 11 and being heated to the preset temperature, ensuring rapid and stable contact between the sample 1 and the coolant 31. This reduces time delay and temperature fluctuations during temperature transition, improving the accuracy of the test.

[0040] It is evident that the design of the first movable rod 42 and the second movable rod 43, made of platinum, being vertically and rotatably connected not only improves the stability and accuracy of the thermal shock resistance measurement device in high-temperature environments, but also simplifies the operation process, enhances equipment safety and long-term operational reliability, and plays an important role in improving the accuracy and efficiency of material thermal shock resistance testing.

[0041] Specifically, the movable component 40 also includes a first controller 44, and the second end of the second movable rod 43 is rotatably connected to the first controller 44 so that the first controller 44 controls the rotation of the second movable rod 43 to drive the bearing part 41 on the first movable rod 42 to move between the first cavity 11 and the second cavity 12. In this way, the movement of the second movable rod 43 can be precisely controlled, thereby ensuring the accuracy and stability of the movement of the bearing part 41 on the first movable rod 42 between the first cavity 11 and the second cavity 12, which helps to reduce the temperature change of the sample during the movement process, thereby improving the accuracy of the thermal shock resistance test.

[0042] A buffer 15 is provided on the furnace body 10 at the edge of the opening of the mounting hole 14, and a second limiting member 420 is provided on the first movable rod 42. The second limiting member 420 is used to limit contact with the buffer 15.

[0043] By cooperating with the buffer 15 and the second limiting member 420, the impact energy of the first movable rod 42 when it contacts the furnace body 10 during movement can be absorbed, reducing mechanical impact, protecting the first movable rod 42 and the furnace body 10 from damage, and extending the service life of the equipment. At the same time, it limits the range of motion of the first movable rod 42, ensuring that the movement of the bearing part 41 between the first cavity 11 and the second cavity 12 does not exceed the predetermined range, improving the accuracy and safety of the testing process. Therefore, the limiting contact ensures the accuracy of each test sample 1 moving to the designated position, reduces the impact of positional changes on the test results, and improves the repeatability and comparability of the test.

[0044] Specifically, the heating assembly 20 includes two heating elements 21, which are respectively disposed within the first cavity 11 and connected to the inner wall of the furnace body 10; wherein the heating element 21 is a silicon molybdenum rod. Using a silicon molybdenum rod as a heating element provides high heating efficiency and uniform heat distribution, which helps to achieve precise temperature control within the first cavity 11, ensuring that the sample 1 under test is uniformly heated during the heating process and improving the accuracy of the test results. Furthermore, the silicon molybdenum rod has good high-temperature stability, capable of operating at temperatures up to 1700℃ without significant performance degradation. This allows the device to perform thermal shock resistance tests under high-temperature conditions, expanding the device's testing range.

[0045] It is evident that using a silicon molybdenum rod as the heating component 21 of the heating assembly 20 not only enables rapid and uniform heating of the sample 1 to be tested, but also ensures testing stability and safety under high-temperature conditions, extends equipment life, and improves testing accuracy and flexibility.

[0046] To simulate extreme temperature changes experienced by the sample 1 under test, the cooling assembly 30 includes a cooling tank 32 and a second controller 33. The cooling tank 32 contains a coolant 31. The second controller 33 is connected to the cooling tank 32 via a connecting pipe 34 to control the temperature of the coolant 31 in the cooling tank 32 at a set temperature. The coolant 31 is deionized water, and / or the set temperature is 25°C.

[0047] In this way, the second controller 33 can precisely adjust the temperature of the coolant 31 to maintain it at the set temperature of 25°C, thus providing a stable cooling environment, which helps to simulate extreme temperature changes and improves the repeatability and accuracy of test results. Deionized water, as the coolant 31, has excellent heat transfer performance and cooling capacity, and can quickly cool the high-temperature test sample 1 to room temperature or lower, simulating extreme temperature changes from high to low temperatures, thereby testing the material's thermal shock resistance. Furthermore, the use of deionized water avoids contamination or corrosion of the test sample 1 or the inside of the device by impurities in the cooling tank 32, ensuring a pure testing environment. At the same time, the rapid cooling capacity of deionized water combined with precise temperature control can greatly shorten the testing cycle, improve testing efficiency, and compared to other cooling media, it is lower in cost, easier to obtain, and has relatively lower long-term maintenance costs.

[0048] Specifically, the thermal shock resistance performance measuring device also includes a temperature measuring component 60, which is disposed within the first cavity 11 to detect the real-time temperature value within the first cavity 11. In this way, the temperature measuring component 60 can monitor the temperature within the first cavity 11 in real time, providing continuous temperature data. It can cooperate with the heating component 20 to achieve closed-loop control of the heating process within the first cavity 11, ensuring that the temperature within the first cavity 11 accurately reaches the set value and remains stable, thus improving the accuracy of temperature control. This significantly improves the temperature control accuracy, testing process reliability, and automation level of the thermal shock resistance performance measuring device, while also supporting data recording and analysis and safety monitoring.

[0049] Specifically, the thermal shock resistance measurement device also includes a control and recording system 70. The temperature measuring component 60, the moving component 40 and the cooling component 30 are respectively connected to the control and recording system 70 via connecting lines, so that the control and recording system 70 can record the real-time temperature value in the first cavity 11, the temperature value of the coolant 31 and control the movement of the bearing part 41.

[0050] The control and recording system 70 allows for centralized control and recording of various key parameters within the device, such as the real-time temperature value within the first chamber 11, the temperature value of the coolant 31, and the control of the movement of the support unit 41. This significantly simplifies the operation process, improves the level of automation in testing, reduces human error, and enhances the accuracy of sample position movement and the repeatability of the testing process. Therefore, the control and recording system 70 greatly improves the automation level of the thermal shock resistance measurement device, the accuracy of data recording and analysis, and the controllability and safety of the testing process.

[0051] In this utility model, the specific usage process is as follows:

[0052] Open the furnace body 10, place the sample 1 to be tested on the support part 41 of the first movable rod 42 at room temperature, close the furnace body 10, control the temperature rise in the first cavity 11, and when the required temperature is reached, control the heat insulation component 51 to open the through hole 13, and then quickly send the sample 1 to be tested into the cooling tank 32 via the support part 41 of the first movable rod 42 through the first controller 44. At the same time, turn off the heating in the first cavity 11, record the temperature in the first cavity 11 detected by the temperature measuring component 60 and the temperature of the coolant 31 in the cooling tank 32 controlled by the second controller 33, and finally observe whether the sample 1 to be tested is damaged. If it is not damaged, repeat the previous steps until the sample 1 to be tested is damaged. The difference between the highest temperature in the first cavity 11 that the sample 1 to be tested can withstand without damage and the constant temperature of the coolant 31 is the thermal shock resistance of the sample 1 to be tested. The larger the temperature difference, the better the thermal shock resistance.

[0053] The following formula is used to calculate the thermal shock resistance of a material:

[0054]

[0055] Where ΔT is the maximum temperature difference that the sample can withstand, i.e., the thermal shock resistance of the material; n is the number of samples; and ΔTn is the maximum temperature difference that the i-th sample can withstand.

[0056] The table below shows the relevant records of thermal shock resistance tests for glass materials A and B. Based on the characteristics of these two types of glass, the temperature control in the first chamber 11 starts from 225℃, which means the temperature difference starts from 200℃, with an interval of 20℃.

[0057] Example 1

[0058] Thermal shock resistance test of glass A:

[0059]

[0060] In the diagram, √ indicates no damage, × indicates damage, and ○ indicates no testing.

[0061] Example 2

[0062] Thermal shock resistance test of glass B:

[0063]

[0064] In the diagram, √ indicates no damage, × indicates damage, and ○ indicates no testing.

[0065] Therefore, glass B exhibits better thermal shock resistance than glass A. It should be noted that to improve the accuracy of thermal shock resistance testing, the testing interval temperature can be reduced, and the number of tests can be increased.

[0066] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0067] The thermal shock resistance measurement device includes a furnace body 10, a heating component 20, a cooling component 30, and a movable component 40. The furnace body 10 has a first cavity 11 and a second cavity 12 spaced apart, which are connected by a through hole 13, which is openable and closable. The heating component 20 is disposed in the first cavity 11 to heat the temperature inside the first cavity 11 to a preset temperature. The cooling component 30 is disposed in the second cavity 12 and is used to contain a coolant 31 at a set temperature. The movable component 40 includes a support part 41 for containing the sample 1 to be tested. The support part 41 is disposed in the first cavity 11 and is movably disposed between the first cavity 11 and the second cavity 12, so that after the first cavity 11 is heated to the preset temperature, the support part 41 moves the sample 1 to be tested into the second cavity 12 and into contact with the coolant 31. By placing the heating component 20 in the first chamber 11, the preset temperature that the sample 1 needs to withstand during testing can be precisely controlled. Simultaneously, by placing the cooling component 30 in the second chamber 12, the coolant 31 can be kept at a constant low temperature, thus enabling accurate measurement of the thermal shock resistance of the sample 1 under rapid temperature changes from high to low. The support component 41 can move rapidly between the first chamber 11 and the second chamber 12, allowing the sample 1 to contact the coolant 31 immediately after reaching the preset temperature in the first chamber 11. This rapid temperature transition simulates the extreme temperature changes that the sample 1 may encounter in practical applications, improving test accuracy and solving the problem of low accuracy in measuring the thermal shock resistance of materials under temperature changes in existing technologies. Furthermore, the design of the movable component 40 automates the testing process, reducing direct operator intervention, improving testing efficiency, and lowering safety risks during operation.
