Description

Technical Field

[0001] The present application belongs to the technical field of alloy material emissivity detection, and in particular, relates to an alloy material emissivity detection platform and detection method. Background Art

[0002] In electric heating devices such as heating furnaces, resistance furnaces and diffusion furnaces, alloy materials are usually used as electric heating elements. The electric heating elements can convert electrical energy into thermal energy and radiate it to achieve a heating effect. The emissivity of the alloy material is an important indicator for evaluating the radiation capacity of the alloy material. If the emissivity of the alloy material is greater, the radiation capacity of the alloy material is stronger, and the heat transferred to the outside will be more. If the emissivity of the alloy material is smaller, it means that the radiation capacity of the alloy material is weaker, which will cause the electric heating device to heat up more slowly and increase power consumption. Therefore, detecting the emissivity of the alloy material is an important step in judging the quality of the alloy material. In the prior art, since the traditional testing device is not resistant to high temperatures, it is impossible to detect the emissivity of the alloy material within a higher temperature range. Based on this, how to improve the temperature range of the emissivity detection of the alloy material is a technical problem that needs to be solved urgently. Summary of the invention

[0029] In order to enable those skilled in the art to better understand the present application, the emissivity of the alloy material proposed in the present application will first be briefly described.

[0030] In electric heating devices such as heating furnaces, resistance furnaces and diffusion furnaces, alloy materials are usually used as electric heating elements. The electric heating elements can convert electrical energy into thermal energy and radiate it to achieve a heating effect. The emissivity of the alloy material is an important indicator for evaluating the radiation capacity of the alloy material. If the emissivity of the alloy material is larger, the radiation capacity of the alloy material is stronger, and the heat transferred to the outside will be more. If the emissivity of the alloy material is smaller, the radiation capacity of the alloy material is weaker, which will cause the electric heating device to heat up more slowly and increase the power consumption. Therefore, detecting the emissivity of the alloy material is an important step in judging the quality of the alloy material. In the prior art, the traditional testing device is not resistant to high temperature. Based on this, the present application proposes an emissivity detection platform and detection method for alloy materials to improve the temperature range of emissivity detection of the alloy material.

[0031] Next, we will combine Figure 1 The emissivity detection platform of alloy materials proposed in this application is briefly described.

[0032] See also Figure 1 , showing a schematic diagram of an emissivity detection platform for alloy materials in one embodiment of the present application.

[0033] like Figure 1 As shown, the platform may at least include a heating device, an infrared temperature measuring device and a data processing device (not shown), the heating device may include a box 101, a heating element, a heat-insulating element and a temperature controller, the box 101 is provided with a hole 102, which can be used to heat the alloy material to a preset temperature; wherein, the box 101 can be used to place the alloy material 104, the heating element can be arranged inside the box, can be used to generate heat to heat the alloy material 104, the heat-insulating element can be arranged outside the box, can be used to prevent heat loss, and the temperature controller can be used to control the temperature inside the box 101.

[0034] In the present application, the heating device may specifically be a muffle furnace, which is a high-temperature electric furnace with good high-temperature resistance and a heating temperature of up to 1300°C; the heating element may specifically be a high-temperature alloy wire or a resistance wire, which has good high-temperature resistance and can maintain a stable resistance value in a high-temperature environment, thereby maintaining the heat supply of the heating element stable; the insulation element may specifically be ceramic fiber or asbestos, which not only has good high-temperature resistance but also has good insulation performance, and can cover the outside of the box of the heating device to prevent heat loss in the box, thereby accelerating the heating speed of the box and maintaining the temperature of the box stable; the temperature controller may detect the temperature of the box in real time to accurately control the temperature of the box, thereby ensuring that the temperature of the box remains stable, and can also adjust the temperature of the box to meet the needs of different experimental conditions.

[0035] In the present application, the alloy material is heated by the heating device, so that the alloy material can be heated to a relatively high temperature, thereby being able to increase the temperature range for detecting the emissivity of the alloy material to a certain extent.

[0036] Continue to refer to Figure 1 As shown, the infrared temperature measuring device at least includes an infrared radiation receiver 105 and a radiation signal processor 103, wherein the infrared radiation receiver 105 can be used to receive the infrared radiation signal emitted by the alloy material. Specifically, the infrared radiation receiver 105 can gather the infrared radiation signal emitted by the alloy material 104 on the radiation sensor through its internal optical system; the radiation signal processor 103 can be used to process the infrared radiation signal received by the infrared radiation receiver and output the measured temperature of the alloy material. Specifically, the radiation signal processor 103 can convert the infrared radiation signal received by the radiation sensor into an electrical signal, and then output the test temperature of the alloy material after being processed by the radiation signal processor 103.

[0037] In the present application, by separating the heating device and the infrared temperature measuring device, damage to high temperature-sensitive components in the infrared temperature measuring device can be avoided, thereby ensuring that the infrared temperature measuring device can operate normally, thereby increasing the temperature range for detecting the emissivity of the alloy material.

[0038] In addition, the data processing device can be used to determine the emissivity of the alloy material at the preset temperature based on the measured temperature. Specifically, the data processing device can be used to adjust the correction coefficient to correct the measured temperature until the measured temperature is corrected to the same as the preset temperature. The correction coefficient when the corrected measured temperature is the same as the preset temperature is used as the emissivity of the alloy material.

[0039] In order to make those skilled in the art better understand the present application, Figure 2 , the emissivity detection method of alloy materials proposed in this application is elaborated in detail.

[0040] See also Figure 2 , shows a flow chart of an emissivity detection method for an alloy material in one embodiment of the present application, the method can be applied to the platform as described above, and the emissivity detection method for the alloy material can be performed at least according to the following steps 210 to 250:

[0041] Step 210: placing the alloy material inside a box of a heating device, with the distance between the alloy material and the hole on the box being a first preset spacing distance, and heating the alloy material by the heating device.

[0042] Step 220, adjusting the position of the infrared temperature measuring device so that the distance between the infrared temperature measuring device and the heating device is a second preset spacing distance.

[0043] Step 230, adjusting the height of the infrared temperature measuring device so that the infrared radiation receiver of the infrared temperature measuring device and the hole on the box body are maintained at the same height.

[0044] Step 240: After the heating device heats the alloy material to a preset temperature, the infrared temperature measuring device is used to determine the measurement temperature of the alloy material.

[0045] Step 250: Determine the emissivity of the alloy material at the preset temperature by a data processing device according to the measured temperature.

[0046] In the present application, the first preset interval distance may be specifically 3 cm, and the second preset interval distance may be specifically 2 cm. According to actual needs, the first preset interval distance and the second preset interval distance may also be other values, and the present application does not make any specific limitation on this.

[0047] In the present application, the diameter of the hole on the box body may specifically be 1.5 cm. According to actual needs, the diameter of the hole may also be other values, and the present application does not make any specific limitation on this.

[0048] In the present application, the preset temperature may specifically be 600° C.<T≤1300° C., wherein T represents the preset temperature.

[0049] In the present application, the alloy material can specifically be an iron-chromium-aluminum alloy. Before the emissivity of the alloy material is detected, the alloy material needs to be processed according to preset specifications. Specifically, the alloy material needs to be processed into a 2×20mm or 1×20mm flat strip shape so as to increase the focusing range of the infrared temperature measuring device on the infrared radiation signal emitted by the alloy material at a preset temperature.

[0050] In the present application, the heating device, the infrared temperature measuring device and the data processing device are separated, so that the high-temperature-resistant components in the infrared temperature measuring device and the data processing device can work normally during the emissivity detection process, thereby improving the temperature range of the emissivity detection of the alloy material. In addition, by heating the alloy material with the heating device, the alloy material can be heated to a preset temperature, and it can also avoid affecting the infrared temperature measuring device and the data processing device, thereby effectively improving the temperature range of the emissivity detection of the alloy material.

[0051] In the above step 250, the emissivity of the alloy material at the preset temperature is determined by a data processing device according to the measured temperature, which can be specifically performed according to the following steps 251 to 253:

[0052] Step 251, traversing the correction coefficients within a preset coefficient range through the data processing device.

[0053] Step 252, correcting the measured temperature by traversing the obtained correction coefficient until the measured temperature is corrected to be the same as the preset temperature.

[0054] Step 253: Correct the measured temperature to a correction coefficient equal to the preset temperature as the emissivity of the alloy material.

[0055] In the present application, the preset coefficient range may specifically be 0.6 to 1.0. According to actual needs, the preset coefficient range may also be other numerical ranges. The present application does not impose too many limitations on this.

[0056] In the present application, the test temperature is the infrared radiation signal generated by the infrared temperature measuring device through the alloy material at a preset temperature. Since the emissivity of the alloy material is not 1, the test temperature and the preset temperature are not equal. The data processing device can use a built-in algorithm to correct the test temperature to be equal to the preset temperature according to the emissivity of the alloy material. Therefore, the correction coefficient when the test temperature is corrected to be equal to the preset temperature is the emissivity of the alloy material. In this way, the measured temperature can be corrected by traversing the correction coefficient within the preset coefficient range on the data processing device, and the measured temperature can be corrected to the correction coefficient when it is the same as the preset temperature as the emissivity of the alloy material.

[0057] It should be noted here that the built-in algorithm of the data processing device can be obtained from the existing technical documents, and this application will not go into details about it.

[0058] In the present application, the data processing device is used to traverse the correction coefficient within the preset coefficient range, correct the measured temperature, and correct the measured temperature to the correction coefficient when it is the same as the preset temperature. This is used as the emissivity of the alloy material, which can improve the accuracy of the emissivity detection of the alloy material to a certain extent, thereby improving the rationality of the design of the alloy material emissivity detection platform, ensuring that the platform can ensure the accuracy of the emissivity detection while improving the temperature range of the alloy material emissivity detection.

[0059] Next, we will combine Figures 3 to 6 , the alloy material emissivity platform and detection method proposed in this application are explained with a specific embodiment.

[0060] In a specific embodiment of the present application, the emissivity detection platform and detection method of the alloy material are used to detect the emissivity of the APM alloy material, the SGHT alloy material, the A-1 alloy material and the HRE alloy material at different temperatures, and a relationship diagram between the emissivity and temperature of various alloy materials is obtained, as shown in the following example. Figures 3 to 6 See Figure 3 , which shows the relationship between the emissivity and temperature of the APM alloy material in one embodiment of the present application; see Figure 4 , which shows the relationship between the emissivity and temperature of the SGHT alloy material in one embodiment of the present application; see Figure 5 , which shows the relationship between the emissivity and temperature of the A-1 alloy material in one embodiment of the present application; see Figure 6, shows a graph showing the relationship between the emissivity and temperature of the HRE alloy material in one embodiment of the present application; from the graph, it can be concluded that the relationship between the emissivity and temperature of the APM alloy material, SGHT alloy material, A-1 alloy material and HRE alloy material at 700°C to 1200°C, respectively, and as the temperature increases, the emissivity of the alloy material will also increase.

[0061] In the present application, the emissivity detection platform and detection method of the alloy material are used to detect the emissivity of the APM alloy material, SGHT alloy material, A-1 alloy material and HRE alloy material at different temperatures. The specific data are shown in Table 1, which shows the emissivity of different alloy materials at different temperatures in the present application.

In this way, the alloy material emissivity detection platform and detection method proposed in the present application can effectively improve the temperature range of the emissivity detection of the alloy material, and can be applicable to a variety of alloy materials.

[0066] Based on the technical solution proposed in the present application, the heating device, the infrared temperature measuring device and the data processing device are separated, so that the high-temperature-resistant components in the infrared temperature measuring device and the data processing device can work normally during the emissivity detection process, thereby improving the temperature range of the emissivity detection of the alloy material. In addition, by heating the alloy material with the heating device, the alloy material can be heated to a preset temperature, and it can also avoid affecting the infrared temperature measuring device and the data processing device, thereby effectively improving the temperature range of the emissivity detection of the alloy material.
