[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0058] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0059] In order to improve efficiency and accuracy, the present application provides a method for determining the robustness of a steel plate. The method for determining the robustness of a steel plate provided in the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0060] Please see attached Figure 1 , Figure 1 A schematic flow chart of a method for determining the robustness of a steel plate provided in an embodiment of the present application. The method may include the following steps:
[0061] Step S101: Obtain a steel plate of preset width.
[0062] In the present application, steel plates of a preset width may be sampled from the produced steel plates along the plate width direction to ensure that the preset width (eg, preset width ≥ 100 mm) is sufficient to represent the characteristics of the steel plate in the width direction.
[0063] Step S102: Divide a steel plate of a preset width into a plurality of steel plate segments along the width direction, and number each steel plate segment.
[0064] It should be noted that each steel plate segment includes an upper point, a midpoint and a lower point. The upper point indicates the top or upper surface of the steel plate segment. The midpoint indicates the center of the steel plate segment, usually located at the midpoint in the thickness direction. The lower point indicates the bottom or lower surface of the steel plate segment. The multi-point testing method helps to identify possible performance differences within the steel plate segment, such as performance fluctuations caused by production processes, material inhomogeneity, etc.
[0065] In the present application, a steel plate of a preset width can be divided into several equal steel plate segments along the width direction and numbered from one side to the other (such as 1, 2, 3, ..., 30). The upper point, middle point and lower point of the first steel plate segment can be marked as 1a, 1b, 1c respectively, and the upper point, middle point and lower point of the remaining steel plate segments continue to be marked in this way.
[0066] Step S103: Based on preset test conditions, a friction test is performed on the odd-numbered steel plate segments to obtain a first dynamic friction performance.
[0067] In the present application, based on preset test conditions, friction tests are performed on the upper point, middle point and lower point of the odd-numbered steel plate segments to obtain the first dynamic friction performance.
[0068] Specifically, a rotary friction testing machine can be used to perform friction tests on the upper, middle and lower points of the odd-numbered steel plate segments, and the preset test conditions can be a vertical force of 80N applied to the steel plate segment, a rotation speed of 50r / min, and a test time of 20s.
[0069] Step S104: Clean the steel plate segments with even numbers, and perform a friction test on the cleaned steel plate segments based on preset test conditions to obtain a second dynamic friction performance.
[0070] In the present application, based on preset test conditions, friction tests are performed on the upper point, middle point and lower point of the cleaned steel plate segment to obtain the second dynamic friction performance.
[0071] Specifically, the even-numbered steel plate segments can be first cleaned by oscillating for five minutes using an ultrasonic cleaner (using petroleum ether as a cleaning solution) to remove possible contaminants or grease on the surface. Then, the upper, middle and lower points of the cleaned steel plate segments are tested for friction using a rotary friction tester, and the test conditions are still 80N of vertical force applied to the steel plate segments, 50r / min of the rotary friction tester speed, and 20s of test time.
[0072] Step S105: Determine the robustness of the steel plate based on the first dynamic friction performance and the second dynamic friction performance.
[0073] In the present application, a kinetic friction coefficient curve is drawn based on the first kinetic friction performance and the second kinetic friction performance. The curve with a positive slope in the kinetic friction coefficient curve is fitted to obtain multiple kinetic friction coefficient rise rates. Based on multiple kinetic friction coefficient rise rates, the robustness of the steel plate is determined. Among them, ignoring the climbing flat area, the positive slope in the kinetic friction coefficient curve indicates that as a certain variable (such as speed, pressure, etc.) increases, the kinetic friction coefficient also increases. By fitting these positive slope parts, multiple kinetic friction coefficient rise rates can be obtained, which quantify the speed at which the kinetic friction coefficient increases with changes in conditions.
[0074] Specifically, based on multiple dynamic friction coefficient increase rates, the robustness of the steel plate is determined, including: drawing a dynamic friction coefficient increase rate curve based on the multiple dynamic friction coefficient increase rates. Obtaining the number of target dynamic friction coefficient increase rates in the dynamic friction coefficient increase rate curve, and the difference between the highest point of the dynamic friction coefficient increase rate and the lowest point of the dynamic friction coefficient increase rate, the target data being a dynamic friction coefficient increase rate greater than the preset data of the previous dynamic friction coefficient increase rate and the next dynamic friction coefficient increase rate, or a dynamic friction coefficient increase rate less than the preset data of the previous dynamic friction coefficient increase rate and the next dynamic friction coefficient increase rate.
[0075] The target data may be convex points or concave points that are significantly inconsistent with the overall trend.
[0076] When the number of target data is not greater than the first preset value, and the difference is not greater than the second preset value, the robustness of the steel plate is determined to be the first robustness. When the number of target data is greater than the first preset value and not greater than the third preset value, or the difference is not greater than the second preset value, the robustness of the steel plate is determined to be the second robustness. When the number of target data is greater than the second preset value, or the difference is greater than the second preset value, the robustness of the steel plate is determined to be the third robustness.
[0077] If there are ≤1 convex and concave points in the dynamic friction coefficient rising rate curve that are significantly inconsistent with the overall trend, and the difference between the highest point and the lowest point is ≤0.05, the robustness of the steel plate is excellent; if there are ≤2 convex and concave points in the dynamic friction coefficient rising rate curve that are significantly inconsistent with the overall trend, or the difference between the highest point and the lowest point is ≤0.05, the robustness of the steel plate is medium; in other cases, the robustness of the steel plate is poor.
[0078] It can also be judged based on the dynamic friction coefficient curve: if there are ≤1 convex points and concave points in the dynamic friction coefficient curve that are significantly inconsistent with the overall trend, and the difference between the highest point and the lowest point is ≤0.05, the robustness of the steel plate is excellent; if there are ≤2 convex points and concave points in the dynamic friction coefficient curve that are significantly inconsistent with the overall trend, or the difference between the highest point and the lowest point is ≤0.05, the robustness of the steel plate is medium; in other cases, the robustness of the steel plate is poor.
[0079] In summary, the present application provides a method for determining the robustness of a steel plate, which comprises obtaining a steel plate of a preset width; dividing the steel plate of the preset width along the width direction to obtain a plurality of steel plate segments, and numbering each steel plate segment; performing a friction test on the odd-numbered steel plate segments based on preset test conditions to obtain a first dynamic friction performance; cleaning the even-numbered steel plate segments, and performing a friction test on the cleaned steel plate segments based on preset test conditions to obtain a second dynamic friction performance; and determining the robustness of the steel plate based on the first dynamic friction performance and the second dynamic friction performance. This solution automatically performs friction testing through preset test conditions and equipment, which greatly saves time, avoids subjective errors, and improves accuracy.
