[0001] This application relates to the technical field of evaluating and testing the technological properties of casting alloys, and particularly to a method for determining the properties of die-casting alloys and a pattern. Background Art

[0002] Casting alloys are important engineering materials and play a quite important role in industrial and agricultural production, national defense construction, and people's daily life. The casting performance of casting alloys has an important impact on aspects such as part structure design, casting process adjustment, product quality, and cost control.

[0003] The fluidity and hot cracking tendency of alloys under casting processes are the two most important indicators for evaluating the casting performance of casting alloys. Currently, the common method for evaluating the fluidity of casting alloys is to judge the fluidity by observing the flow length of the alloy liquid in a single spiral specimen or a horizontal straight bar specimen. The common method for evaluating the hot cracking tendency of casting alloys is to evaluate the hot cracking performance by observing the length and critical size of the generated hot cracks. However, the above methods can only evaluate the fluidity and hot cracking tendency of alloys formed under gravity casting, and cannot evaluate the fluidity and hot cracking tendency of alloys formed under die-casting processes. Summary of the Invention

[0004] Based on this, in view of the above technical problems, it is necessary to provide a method for determining the properties of die-casting alloys and a pattern that can evaluate the fluidity and hot cracking tendency of die-casting alloys.

[0011] In one embodiment, the diameters of the hot cracking balls in different flow channels are the same, and the diameter of the hot cracking ball is greater than the diameter of the cross-section of the largest flow channel.

[0015] Obtain die-cast samples;

[0016] The properties of the die-casting alloy are determined based on the alloy filling length of the flow channel and the state of the hot cracked spheres in the flow channel of the sample corresponding to the pattern.

[0017] In one embodiment, determining the die-casting alloy properties based on the alloy-filled length of the flow channel corresponding to the sample pattern and the state of hot-cracked spheres in the flow channel includes:

[0018] Obtain the alloy filling length of the flow channel corresponding to each sample;

[0019] When the alloy filling length of the flow channel corresponding to the first sample is greater than the alloy filling length of the flow channel corresponding to the second sample, the fluidity of the alloy corresponding to the first sample is better than the fluidity of the alloy corresponding to the second sample.

[0020] When the alloy filling length of the flow channel corresponding to the first sample is greater than the alloy filling length of the flow channel corresponding to the second sample, the fluidity of the alloy corresponding to the first sample is better than that of the alloy corresponding to the second sample in a channel with a predetermined cross-section.

[0021] In one embodiment, determining the die-casting alloy properties based on the alloy filling length of the flow channel corresponding to the sample pattern and the state of hot cracked spheres in the flow channel further includes:

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The method for determining the properties of die-casting alloys provided by the embodiments of the present application can be applied to a die-casting alloy property determination pattern as shown in Figure 1 and Figure 2 wherein Figure 1 is a schematic structural diagram of the die-casting alloy property determination pattern, Figure 2 and Figure 1 is the sectional view taken along line A-A in . The die-casting alloy property determination pattern includes a pattern center 11, a flow channel 12 and a hot crack ball 13, and the overall structure of the pattern is similar to the character "卍". A die-casting inlet gate is provided in the pattern center 11, the flow channel 12 extends from the pattern center as a starting point, and the hot crack ball 13 is located in the flow channel, wherein the flow channel 12 includes a horizontal channel 121 and a vertical channel 122.

[0039] In some embodiments, there are multiple flow channels 12, and the diameters of the cross-sections of the flow channels 12 are different. For example, the pattern has 4 flow channels, and the diameters of each flow channel are 6 mm, 10 mm, 14 mm and 16 mm respectively. In other embodiments, the diameters of the flow channels can be other values, and specific limitations are not made here. In some embodiments, the cross-section of the flow channel 12 is circular, and in other embodiments, the cross-section of the flow channel 12 can be other shapes.

[0040] In some embodiments, the flow channel 12 extends in a "回" (Chinese character for "return") shape starting from the pattern center 11, and the horizontal channel 121 and the vertical channel 122 of the flow channel 12 are connected by the hot crack ball 13. The center of the hot crack ball 13 is located at the intersection center of two adjacent horizontal channels 121 and vertical channels 122. The horizontal channel 121 of each flow channel 12 is perpendicular to the vertical channel 122, and the horizontal channels 121 of all the flow channels 12 are parallel to each other, and the vertical channels 122 of all the flow channels 12 are parallel to each other.

[0041] In one embodiment, the diameters of the hot crack balls 13 in different flow channels 12 are the same, and the diameter of the hot crack ball 13 is greater than the cross-section diameter of the largest flow channel. For example, the diameters of the 4 flow channels of the pattern are 6 mm, 10 mm, 14 mm, 16 mm respectively, and the diameter of the hot crack ball in the flow channel can be 18 mm.

[0042] In one embodiment, the pattern center 11 has a centrally symmetrical structure, the flow channel 12 has a cross-sectional diameter of 2mm to 20mm, the thermally splitting sphere 13 has a diameter of 3mm to 60mm, the distance between two adjacent horizontal channels 121 is 4mm to 100mm, the distance between two adjacent vertical channels 122 is 4mm to 100mm, the number of horizontal channels in each flow channel 12 is 1 to 10, the number of vertical channels in each flow channel 12 is 1 to 10, and the total length of each flow channel 12 is 100mm to 5000mm.

[0043] In one embodiment, the pattern center 11 is a cylindrical structure, the flow channel 12 has a cross-sectional diameter of 3mm to 16mm, the thermally splitting sphere 13 has a diameter of 6mm to 30mm, the distance between two adjacent horizontal channels 121 is 10mm to 60mm, the distance between two adjacent vertical channels 122 is 10mm to 60mm, each flow channel 12 has 2 to 5 horizontal channels, each flow channel 12 has 2 to 5 vertical channels, and the total length of each flow channel 12 is 300mm to 3000mm.

[0044] In one embodiment, the pattern center 11 is a cylindrical structure, the flow channel 12 has a cross-sectional diameter of 3mm to 12mm, the thermally splitting sphere 13 has a diameter of 10mm to 30mm, the distance between two adjacent horizontal channels 121 is 15mm to 40mm, the distance between two adjacent vertical channels 122 is 15mm to 40mm, each flow channel 12 has 2 to 4 horizontal channels, each flow channel 12 has 2 to 4 vertical channels, and the total length of each flow channel 12 is 600mm to 2000mm.

[0045] In one embodiment, such as Figure 3 As shown, a method for determining the properties of die-casting alloys is provided, which can be applied to... Figure 1 Taking the appearance in the image as an example, the following steps are included:

[0046] S301, Obtain the die-cast sample.

[0047] In this step, the die-cast sample is... Figure 1 The model consists of alloy samples formed using different alloys or different die-casting processes.

[0048] S302, the properties of the die-casting alloy are determined based on the alloy filling length of the flow channel corresponding to the sample pattern and the state of the hot cracked spheres in the flow channel.

[0049] In this step, the properties of the die-casting alloy include its fluidity, filling properties, hot cracking resistance, shrinkage, and tendency to produce shrinkage cavities and porosity. In other embodiments, the properties of the die-casting alloy can be different and are not specifically limited. For example, the filling properties of the alloy can be quantitatively assessed by measuring the filling length of the alloy in the flow channel, and the shrinkage and tendency to produce shrinkage cavities and porosity can be qualitatively assessed by analyzing the internal defects of the hot cracked spheres.

[0050] The method provided in this embodiment first obtains a die-cast sample, and then determines the properties of the die-cast alloy based on the alloy filling length of the flow channel corresponding to the sample pattern and the state of the hot crack spheres in the flow channel. This method can evaluate the fluidity and hot cracking properties of the alloy formed under the die-casting process.

[0051] Reference Figure 4 , Figure 4 This is a flowchart illustrating an alloy fluidity evaluation step provided in an embodiment of this application. This embodiment relates to an optional implementation method for evaluating alloy fluidity. The die-casting alloy properties are determined based on the alloy filling length of the flow channel corresponding to the sample pattern and the state of hot-cracked spheres in the flow channel, including:

[0052] S401, obtain the alloy filling length of the flow channel corresponding to each sample.

[0053] In this step, all samples are first designated as Sample A, Sample B, etc. Then, the alloy filling length in each flow channel corresponding to each sample is measured, and the alloy filling length of each sample is denoted as L according to the flow channel diameter from largest to smallest. 1A L 2A L 3A L 4A L 1B L 2B L 3B L 4B …

[0054] S402, when the alloy filling length of the flow channel corresponding to the first sample is greater than the alloy filling length of the flow channel corresponding to the second sample, the fluidity of the alloy corresponding to the first sample is better than the fluidity of the alloy corresponding to the second sample.

[0055] In this step, the first sample refers to... Figure 1 The pattern shown refers to the sample formed using the first alloy or the first die-casting process; the second sample refers to the sample formed using the first alloy or the first die-casting process. Figure 1 The flow channels of the sample shown are formed using a different alloy or a different die-casting process.

[0056] For example, the alloy fill length of all flow channels corresponding to sample A is greater than the alloy fill length of all flow channels corresponding to sample B, that is, L is satisfied simultaneously.1A >L 1B L 2A >L 2B L 3A >L 3B L 4A >L 4B This indicates that the fluidity of the alloy or die-casting process represented by sample A is better than that of the alloy or die-casting process represented by sample B.

[0057] S403, when the alloy filling length of the flow channel corresponding to the first sample is greater than the alloy filling length of the flow channel corresponding to the second sample, the fluidity of the alloy corresponding to the first sample is better than that of the alloy corresponding to the second sample in the predetermined cross-section channel.

[0058] In this step, for example, due to the influence of factors such as gravity, inclusions, pouring and mold conditions during die casting, the alloy filling length of the flow channel corresponding to sample A may only be partially greater than the alloy filling length of the flow channel corresponding to sample B, that is, L cannot be satisfied simultaneously. 1A >L 1B L 2A >L 2B L 3A >L 3B L 4A >L 4B This indicates that the alloy or die-casting process represented by sample A has better fluidity than the alloy or die-casting process represented by sample B, only under specific cross-sectional channels.

[0059] The method provided in this embodiment has multiple flow channels of different diameters in the pattern. Compared with the existing single spiral channel pattern, it is superior in terms of data consistency, stability and data reproducibility when verifying the flow performance of die-cast alloys. The flowability can be quantitatively evaluated by measuring the filling length of the alloy in the four flow channels.

[0060] In some embodiments, determining the die-casting alloy properties based on the alloy filling length of the flow channel of the sample corresponding to the pattern and the state of the hot cracked spheres in the flow channel further includes: obtaining the diameter of the flow channel of the sample corresponding to the pattern; obtaining the distance between the hot cracked spheres of the sample corresponding to the pattern and the center of the pattern; determining the number of the hot cracked spheres based on the diameter and the distance; and determining the hot crackability of the die-casting alloy based on the state and number of the hot cracked spheres.

[0061] In this step, Figure 1 The four flow channels of the pattern shown are labeled L1, L2, L3, and L4 in descending order of diameter. The thermally fractured spheres on each flow channel are numbered L in descending order of distance from the center of the pattern. 11 L 12 L 13 L14 ...; L 21 L 22 L 23 L 24 ...; L 31 L 32 L 33 L 34 ...; L 41 L 42 L 43 L 44 ...

[0062] Assigning values ​​to hot-cracked spheres: aligning with L 41 L 42 L 43 L 44 ...the thermal cracking spheres are assigned values ​​increasing by 1 sequentially, 1, 2, 3, 4...; for the marker L... 31 L 32 L 33 L 34 ...the thermal cracking spheres are assigned values ​​increasing by 1 sequentially, followed by values ​​2, 3, 4, 5...; for the marker L... 21 L 22 L 23 L 24 ...the thermal cracking spheres are assigned values ​​increasing by 1 sequentially, then 3, 4, 5, 6...; for the marker L... 11 L 12 L 13 L 14 ...The thermal cracking spheres are assigned values ​​increasing by 1 in sequence, for example, 4, 5, 6, 7...

[0063] For example, in Figure 1 The die-cast sample in the pattern shown has three cracks. The hot crack ball closest to these three crack locations is assigned a value of 2, 4, and 5 respectively. Adding the values ​​of these three hot crack balls gives the quantitative value of the hot crackability of the alloy.

[0064] The method provided in this embodiment allows for a more thorough evaluation and verification of the hot cracking properties of the die-cast alloy by having the pattern intersect with the hot cracking sphere through four flow channels of different diameters and lengths. By analyzing whether cracks or fissures exist in each flow channel and at the intersection of the flow channel and the hot cracking sphere, the hot cracking performance of the alloy can be quantitatively evaluated. A single die-casting process can simultaneously evaluate the fluidity and hot cracking performance of the alloy, saving on mold opening costs and the number of verification samples.

[0065] In some embodiments, determining the hot crackability of the die-cast alloy based on the state and number of the hot cracking spheres includes: determining the hot cracking factor of each flow channel based on the state and number of the hot cracking spheres; and determining the hot crackability of the die-cast alloy based on the hot cracking factor.

[0066] In this step, the cracking status of all thermally cracked spheres in the sample at the intersection with the corresponding horizontal and / or vertical channels is statistically analyzed. If there is no cracking at the intersection, the thermal cracking factor at that location is 0. If cracking exists at the intersection, the thermal cracking factor at that location is equal to the maximum value assigned to the thermally cracked spheres at both ends of the cracked horizontal or vertical channel. The statistically analyzed thermal cracking factors on the sample are then summed to obtain the thermal cracking degree value H.

[0067] The higher the calculated H value, the greater the hot cracking resistance of the corresponding alloy or die-casting process. For example, if the H value of the die-cast sample of the first alloy is 10 and the H value of the die-cast sample of the second alloy is 15, then the hot cracking resistance of the second alloy is greater than that of the first alloy.

[0068] The method provided in this embodiment uses the numerical value of hot cracking degree to characterize the magnitude of hot cracking in alloys, making the evaluation of hot cracking in alloys more accurate and intuitive.

[0069] In one embodiment, the pattern center is a cylindrical structure with a diameter of 70 mm, a height of 20 mm, and a draft angle of 1.5°. The cross-sectional diameters of the four flow channels of the pattern are 4 mm, 6 mm, 8 mm, and 10 mm, respectively, and the diameter of the hot cracking sphere is 20 mm. The center distance between two adjacent horizontal channels and vertical channels is 30 mm, and each flow channel has 3 to 4 horizontal and vertical channels. The lengths of the horizontal or vertical channels of each flow channel, from closest to furthest from the pattern center, are: 60 mm, 120 mm, 180 mm, 240 mm, 300 mm, 360 mm, and 420 mm, respectively, with a total length of 1680 mm for a single flow channel. Using this pattern, YL113 alloy samples were produced by die casting at 670°C. The flow and hot cracking properties of the die-cast YL113 alloy samples are statistically shown in Table 1. The determination of the hot cracking degree is based on the following... Figure 5 As shown.

[0071]

[0072] In another embodiment, the pattern center is a cylindrical structure with a diameter of 70 mm, a height of 20 mm, and a draft angle of 2°. The diameters of the four flow channels of the pattern are 3 mm, 6 mm, 9 mm, and 12 mm, respectively, and the diameter of the hot cracking sphere is 30 mm. The center distance between two adjacent horizontal channels and vertical channels is 40 mm. Each flow channel has 3 to 4 horizontal and vertical channels. The lengths of the horizontal or vertical channels of each flow channel, from closest to farthest from the pattern center, are: 50 mm, 130 mm, 210 mm, 290 mm, 370 mm, 450 mm, and 530 mm, respectively, with a total length of 2030 mm for a single flow channel. Using this pattern, YL113 alloy samples were produced by die casting at 670°C. The flow and hot cracking properties of the die-cast YL113 alloy samples are statistically shown in Table 2.
