[0002] To ensure consistent management of cast iron material properties, pre-set standards are typically established to provide unified technical specifications for the production, inspection, and acceptance of cast iron materials. These pre-set standards specify the mechanical properties corresponding to different material grades, standardize the production of cast iron materials, and ensure the stability of production quality.

[0003] However, since the thickness of the cast iron material used in the product is not fixed, it may fall outside the preset thickness range required by the standard, making it impossible to accurately determine the mechanical properties of the cast iron material. To avoid errors in the mechanical properties of the cast iron material, it is necessary to perform material property calibration through actual dissection, which consumes a lot of manpower and resources. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, and equipment for predicting the performance of cast iron materials based on solidification time. It establishes a first performance relationship using a first cast iron material within a preset thickness range of a preset standard requirement, and predicts the mechanical properties of a second cast iron material outside the preset thickness range based on the verified first performance relationship. When determining the second cast iron material, it is not necessary to dissect the casting body, saving manpower and material costs, and saving mechanical performance testing time.

[0005] To address the aforementioned technical problems, embodiments of the present invention provide a method for predicting the performance of cast iron materials based on solidification time, comprising: establishing a first performance relationship for a first cast iron material; wherein the first performance relationship reflects the functional relationship between the mechanical properties of the first cast iron material and the solidification time, and the thickness of the first cast iron material is within a preset thickness range required by a preset standard; obtaining the solidification time of a second cast iron material; wherein the thickness of the second cast iron material is outside the preset thickness range; measuring the actual mechanical properties of the second cast iron material; predicting the predicted mechanical properties of the second cast iron material using the first performance relationship; comparing the actual mechanical properties and the predicted mechanical properties, and if the comparison result meets a preset condition, predicting the mechanical properties of the second cast iron material using the first performance relationship; otherwise, correcting the first performance relationship.

[0009] Compared to related technologies, this invention establishes a first performance relationship for a first cast iron material. This first performance relationship reflects the functional relationship between the mechanical properties of the first cast iron material and its solidification time, with the thickness of the first cast iron material falling within a preset thickness range required by a preset standard.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0019] The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with and referenced by each other without contradiction.

[0020] This invention relates to a method for predicting the performance of cast iron materials based on solidification time. The core of this method involves: establishing a first performance relationship for a first cast iron material; wherein the first performance relationship reflects the functional relationship between the mechanical properties of the first cast iron material and its solidification time, and the thickness of the first cast iron material is within a preset thickness range required by a preset standard; obtaining the solidification time of a second cast iron material; wherein the thickness of the second cast iron material is outside the preset thickness range; measuring the actual mechanical properties of the second cast iron material; predicting the predicted mechanical properties of the second cast iron material using the first performance relationship; comparing the actual mechanical properties and the predicted mechanical properties; if the comparison result meets preset conditions, then the mechanical properties of the second cast iron material are predicted using the first performance relationship; if the preset conditions are not met, then the first performance relationship is corrected. This saves manpower and material resources, and reduces mechanical property testing time. The implementation details of this method for predicting the performance of cast iron materials based on solidification time are described below. The following details are provided for ease of understanding and are not essential for implementing this solution.

[0021] The method for predicting the properties of cast iron materials based on solidification time in this embodiment is as follows: Figure 1 As shown, it specifically includes: Step 101: Establish the first property relationship of the first cast iron material; The first performance relationship is used to reflect the functional relationship between the mechanical properties of the first cast iron material and the solidification time. The functional relationship between mechanical properties and solidification time is usually linear, for example, a linear function in two variables. The mechanical properties of the first cast iron material can be tensile strength, yield strength, elongation, or hardness, etc.

[0022] In addition, the thickness of the first cast iron material is within the preset thickness range required by the preset standard. The preset standard can be EN1563, which specifies the mechanical property requirements for materials with a wall thickness of less than or equal to 200 mm, that is, the preset thickness range is less than or equal to 200 mm.

[0023] Step 102: Obtain the solidification time of the second cast iron material; Wherein, the thickness of the second cast iron material is outside the preset thickness range. In the case where the preset thickness range mentioned above is less than or equal to 200 mm, the thickness of the second cast iron material here is greater than 200 mm.

[0024] The solidification time of the second cast iron material is simulated using analysis software. Specifically, a geometric model of the second cast iron material is created and imported into the analysis software. Thermal properties, such as thermal conductivity and specific heat capacity, are selected within the software. The solidification process of the second cast iron material is simulated to determine the solidification time. To ensure the accuracy of the solidification time, multiple simulations can be performed, and the average value is taken.

[0025] Step 103: Measure the actual mechanical properties of the second cast iron material; Specifically, based on the thickness of the second cast iron material and the solidification time obtained from the simulation, a physical test block was designed and obtained. The test block was processed using the same melting and processing technology as the physical sample. Mechanical property tests were performed on the test block to obtain its actual mechanical properties, which can represent the actual mechanical properties of the second cast iron material.

[0026] Step 104: Predict the mechanical properties of the second cast iron material using the first performance relationship; Step 105: Compare the actual mechanical properties with the predicted mechanical properties. If the comparison results meet the preset conditions, the mechanical properties of the second cast iron material are predicted using the first performance relationship formula. If the preset conditions are not met, the first performance relationship formula is corrected.

[0027] Specifically, when the solidification time is the same, the actual mechanical properties and the predicted mechanical properties are compared. If the difference between the actual and predicted mechanical properties is small, the comparison result is deemed to meet the preset conditions; if the difference is large, the preset conditions are not met. The magnitude of the difference can be determined based on the error between the actual and predicted mechanical properties. For example, the preset condition could be set to: the error between the actual and predicted mechanical properties is less than 3%. Alternatively, the difference in solidification time under the same mechanical properties can be used to determine whether the preset conditions are met. For example, the preset condition could be set to: the difference in solidification time is less than or equal to 9000 seconds. Appropriate parameter values ​​for the preset conditions can be selected based on the actual situation. For example, if higher accuracy of mechanical properties is required, a smaller parameter value can be set for the preset conditions, and so on.

[0028] If the comparison results meet the preset conditions, the mechanical properties of the second cast iron material are predicted using the first performance relationship, which improves the prediction efficiency.

[0029] If the preset conditions are not met, the first performance relationship is corrected. Specifically, based on several actual mechanical properties of the second cast iron material measured at different solidification times, and several predicted mechanical properties obtained from the first performance relationship at the corresponding solidification times, a deviation coefficient is determined; the deviation coefficient is then used to correct the first performance relationship. For example, the first performance relationship is Y=k1X+b, where Y represents solidification time, X represents tensile strength, k1 represents slope, and b represents intercept. The deviation coefficient is deduced to be k2, so the corrected first performance relationship is Y=k2(k1X+b).

[0030] In addition, before predicting the mechanical properties of the second cast iron material of different thicknesses, it is necessary to compare the actual mechanical properties and the predicted mechanical properties, and to determine that the comparison results meet the preset conditions. Then, the first performance relationship is used to predict the mechanical properties to ensure the accuracy of the prediction results.

[0031] Compared to related technologies, this invention establishes a first performance relationship for a first cast iron material. This first performance relationship reflects the functional relationship between the mechanical properties of the first cast iron material and its solidification time, with the thickness of the first cast iron material falling within a preset thickness range required by a preset standard. The solidification time of a second cast iron material is obtained, with the thickness of the second cast iron material falling outside the preset thickness range. The actual mechanical properties of the second cast iron material are measured. The predicted mechanical properties of the second cast iron material are predicted using the first performance relationship. The actual mechanical properties and the predicted mechanical properties are compared. If the comparison result meets preset conditions, the mechanical properties of the second cast iron material are predicted using the first performance relationship. If the preset conditions are not met, the first performance relationship is corrected, and then the corrected first performance relationship is used to predict the mechanical properties. This improves the accuracy and reliability of the prediction results and saves manpower and time compared to the method of measuring each cast iron material individually. Furthermore, the prediction method using the relationship does not require damage to the physical material, saving material costs.

[0032] The mechanical property prediction method of the present invention is not affected by the thickness required by the preset standard, and can accurately predict the thickness of cast iron materials of any thickness.

[0033] In another embodiment of the present invention, the method for predicting the properties of cast iron materials based on solidification time, compared with the above embodiment, after establishing the first property relationship of the first cast iron material, verifies the first property relationship using test blocks. If the verification fails, the first property relationship is re-established to improve the accuracy of the first property relationship in predicting mechanical properties.

[0034] The method for predicting the properties of cast iron materials based on solidification time in this embodiment, such as... Figure 2 As shown, it specifically includes: Step 201: Use software simulation to determine the solidification time of the first cast iron material; Specifically, a geometric model of the first cast iron material is established, and then imported into the analysis software to simulate the solidification process of the first cast iron material and determine the solidification time. The material grades of the first cast iron material and the second cast iron material to be predicted can be GJS400 or GJS500, more specifically EN-GJS-400-18-LT and EN-GJS-500-140. The solidification time can be specifically the solidification time at the location where the solid material is sampled, and the mechanical properties are also the mechanical properties at that location.

[0035] Step 202: Establish the first property relationship based on the solidification time and the standard mechanical properties corresponding to the first cast iron material; Step 203: Verify the first performance relationship using a test block. If the verification fails, return to step 201 and re-execute steps 201 and 202 to re-establish the first performance relationship. Continue until the verification passes, then proceed to step 204 to complete the establishment of the first performance relationship.

[0036] Specifically, the test block is established based on the solidification time calculated in the simulation above and the thickness of the first cast iron material. That is, the solidification time of the test block is consistent with that of the first cast iron material in the software simulation, and the thickness (wall thickness) of the test block is also consistent with that of the first cast iron material in the software simulation. Tensile tests are used to determine the tensile strength, yield strength, and elongation of the test block, and hardness tests are used to check the hardness of the test block. The tensile strength, yield strength, elongation, and hardness mentioned above can all be used as mechanical properties. When testing the mechanical properties of the test block, multiple measurements can be taken and the average value is calculated to avoid the influence of accidental factors on the test results.

[0037] The actual solidification times of the test blocks were 1090s, 2420s, 3380s, 3245s, and 4718s, with corresponding measured tensile strengths of 517.5MPa, 515.25MPa, 514MPa, 506.25MPa, and 505.75MPa. Based on these measured data, the fitting function formula can be obtained as Y = -204.21X + 107474, where Y represents the solidification time and X represents the tensile strength. If the measured fitting function formula matches the established first performance relationship, the verification is successful. If the measured fitting function formula differs significantly from the first performance relationship, the verification fails. Alternatively, under the same solidification time, the measured mechanical properties are compared with the mechanical properties predicted using the first performance relationship. If the two differ significantly, the verification fails. If they are nearly identical or within the preset error range, the verification is successful. The successful verification indicates that the mechanical properties of the test block can substitute for those of the solid.

[0038] In addition, both the first and second cast iron materials can be ductile iron, and the test block can be a stepped-shaped test block.

[0039] In this embodiment, after establishing the first performance relationship, the first performance relationship is verified using a test block made of the first cast iron material to ensure that the first performance relationship can accurately reflect the mechanical properties of the first cast iron material, thereby providing an accurate reference benchmark for the subsequent prediction of the mechanical properties of the second cast iron material and ensuring the accuracy of the prediction of the mechanical properties of the second cast iron material.

[0040] This invention relates to a device for predicting the properties of cast iron materials based on solidification time, such as... Figure 3 As shown, it includes: a setup module, an acquisition module, a measurement module, a prediction module, and a comparison module.

The acquisition module is used to acquire the solidification time of a second cast iron material. The thickness of the second cast iron material is outside the preset thickness range. The measurement module is used to measure the actual mechanical properties of the second cast iron material. The prediction module is used to predict the predicted mechanical properties of the second cast iron material using the first performance relationship. The comparison module is used to compare the actual mechanical properties and the predicted mechanical properties. If the comparison result meets preset conditions, the mechanical properties of the second cast iron material are predicted using the first performance relationship; otherwise, the first performance relationship is corrected.

[0041] In addition, a module is established to determine the solidification time of the first cast iron material using software simulation; based on the solidification time and the standard mechanical properties corresponding to the first cast iron material, a first property relationship is established.

[0042] In addition, the cast iron material performance prediction device based on solidification time also includes: a verification module, which is used to verify the first performance relationship using a test block. If the verification fails, the first performance relationship is re-established; the test block is established based on the solidification time and thickness of the first cast iron material.

[0043] Furthermore, when the mechanical property is tensile strength, the first property relationship is: Y = -204.21X + 107474. Here, Y represents the setting time, and X represents the tensile strength.

[0044] In addition, the comparison module is also used to determine the deviation coefficient based on several actual mechanical properties of the second cast iron material measured at different solidification times, and several predicted mechanical properties obtained from the first performance relationship at the corresponding solidification times; and to correct the first performance relationship using the deviation coefficient.

Based on this relationship, the mechanical properties of a second cast iron material exceeding the preset thickness range are verified and predicted. This saves testing time and reduces manpower consumption. Mechanical property verification is performed using test blocks instead of destructive methods, saving casting resource costs. Verifying the first performance relationship before applying it to predict the mechanical properties of the second cast iron material exceeding the preset thickness range improves the accuracy and reliability of the prediction results.
