Description

Technical Field

[0001] This invention belongs to the field of inspection and testing, and relates to a template ruler for recording parameters of hot working curves and a testing method thereon. Background Technology

[0002] Hot working generally uses curve recording to reflect the actual situation of process parameters, requiring the detection of whether the real-time parameters of the hot working process meet the requirements. Traditional curve recording parameter detection methods cannot provide intuitive measurement conclusions, so common hot working parameters are generally calculated using formulas (1) and (2):

[0003]

[0004]

[0005] Among these, the vertical length of the curve is usually measured using a ruler or a flat ruler, which introduces a certain degree of error; the temperature difference is usually calculated based on the horizontal temperature scale on the curve record, which is dense and prone to miscounting; and the time parameters of common heat treatment processes are in min and the speed is in ℃ / h, while the paper feed speed of the curve record is in mm / h, making unit conversion prone to errors.

[0006] Currently, the detection of parameters for recording thermal processing curves requires calculations according to formulas. These calculations are susceptible to human error, necessitating skilled personnel and a relatively long testing cycle. Therefore, finding an efficient and accurate tool for detecting curve recording parameters is an urgent problem to be solved. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a template ruler and detection method for recording parameters of hot working curves.

[0008] To achieve the above objectives, the present invention employs the following technical solution:

[0010] The heat preservation time measurement scale is based on minutes, and the distance between adjacent scale lines is:

[0011]

[0012] The unit for the paper feed rate of the hot processing curve is mm / h, and the unit for the distance is mm.

[0013] The heating rate measurement scale uses the heating rate as the unit, and the slope angle of each scale line is:

[0018] The scale lines of the heating rate detection scale are labeled with heating rate sequence numbers;

[0019] The heating rate sequence number correspondence table is used to show the correspondence between heating rate sequence number and heating rate.

[0020] Optionally, the test template ruler body is made of transparent plastic.

[0021] Optionally, the left boundary line of the heating rate detection scale is a straight line, and the right boundary line is an arc.

[0022] Optionally, the temperature rise rate difference between adjacent scale lines of the temperature rise rate detection scale is 10℃ / h.

[0023] Optionally, the scale lines of the heating rate detection scale and the holding time detection scale are numbered every four scale lines.

[0024] Optionally, both the heat preservation time detection scale and the heating rate detection scale are located below the heating rate sequence number correspondence table, and the heat preservation time detection scale is located to the left of the heating rate detection scale.

[0025] Optionally, both the heat preservation time detection scale and the heating rate detection scale are marked on the right side of the scale line.

[0026] Optionally, the line width of the scale lines of the heat preservation time detection scale and the heating rate detection scale is smaller than the line width of the heat treatment curve, the drawing deviation of the slope angle of the scale line of the heating rate detection scale is less than 0.007°, and the drawing deviation of the line length between adjacent scale lines of the heat preservation time detection scale is less than 0.01mm.

[0027] Optionally, the line width of the scale lines of the heat preservation time detection scale and the heating rate detection scale is 0.1 mm.

[0028] In a second aspect, the present invention provides a method for detecting the recording parameters of a heat treatment curve based on the above-mentioned heat treatment curve recording parameter detection template, comprising:

[0029] The heat preservation time test procedure is as follows: Cover the heat preservation time test scale of the test template ruler onto the heat preservation section of the heat treatment curve, align the 0 mark of the heat preservation time test scale with the starting position of the heat preservation section curve, and read the scale of the heat preservation time test scale corresponding to the ending position of the heat preservation section curve to obtain the heat preservation time of the heat treatment curve.

[0030] Quantitative detection steps for heating rate: Cover the heating rate detection scale onto the heating segment of the heat treatment curve, and align the left boundary line of the heating rate detection scale with the temperature grid line of the heat treatment curve. Read the serial number of the scale line of the heating rate detection scale that coincides with the heating segment curve to obtain the target heating rate serial number; look up the heating rate serial number in the heating rate serial number correspondence table to obtain the heating rate of the heat treatment curve.

[0031] Qualitative testing steps for heating rate: Obtain the heating rate of the heat treatment curve, and refer to the heating rate sequence number correspondence table according to the heating rate of the heat treatment curve to obtain the target heating rate sequence number of the heat treatment curve; cover the heating rate detection scale onto the heating segment of the heat treatment curve, and align the left boundary line of the heating rate detection scale with the temperature grid line of the heat treatment curve, and determine whether the heating segment curve is within the scale line range corresponding to the target heating rate sequence number of the heat treatment curve. When the heating segment curve is within the scale line range corresponding to the target heating rate sequence number of the heat treatment curve, the heating rate of the heat treatment curve is qualified; otherwise, the heating rate of the heat treatment curve is unqualified.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings:

[0038] See Figure 1 In one embodiment of the present invention, a heat treatment curve recording parameter detection template ruler is provided, including a detection template ruler body made of transparent material; the detection template ruler body is provided with a heat preservation time detection scale, a heating rate detection scale, and a heating rate sequence number correspondence table.

[0039] The heat preservation time measurement scale is based on minutes, and the distance between adjacent scale lines is:

[0040]

[0041] The unit for the paper feed rate of the hot processing curve is mm / h, and the unit for the curve length is mm.

[0042] The heating rate measurement scale uses the heating rate as the unit, and the slope angle of each scale line is:

[0043]

[0044]

[0045]

[0046] The unit for the horizontal temperature difference of the hot working curve is ℃, the unit for the heating rate is ℃ / h, the unit for the temperature difference of the small grid of the hot working curve is ℃, and the unit for the horizontal length of the small grid of the hot working curve is mm.

[0047] The scale lines of the heating rate detection scale are labeled with heating rate serial numbers; the heating rate serial number correspondence table is used to show the correspondence between the heating rate serial number and the heating rate.

[0048] This invention relates to a heat treatment curve recording parameter detection template. By setting up holding time and heating rate detection scales, calculations are eliminated during heat treatment curve recording parameter detection. The scales are simply placed over the corresponding positions of the recorded parameters, and the detection conclusion is directly obtained by comparing them with the heat treatment curve. This reduces human intervention and solves the problems of wasted time and high error rates in traditional curve recording detection calculations. The use of this heat treatment curve recording parameter detection template significantly improves inspection efficiency and ensures accurate and reliable test results. Furthermore, since adjacent scale lines of the heating rate detection scale are close together, they are distinguished by serial numbers. The scale lines of the heating rate detection scale are numbered using heating rate serial numbers, and a heating rate serial number correspondence table is set up to show the relationship between the heating rate serial number and the heating rate, effectively simplifying the heating rate detection scale.

[0049] In one possible implementation, the test template ruler body is made of transparent plastic.

[0050] Specifically, the test template ruler measures parameters by comparing the scale lines with the heat treatment curve. During testing, the scale lines of the test template ruler are directly placed over the heat treatment curve for comparison and conclusion. Therefore, in this embodiment, a heat treatment curve recording parameter test template ruler is made by plotting the test scale and other relevant information on a transparent plastic material with good transparency.

[0051] In one possible implementation, the left boundary line of the heating rate detection scale is a straight line, and the right boundary line is an arc.

[0052] Optionally, the temperature rise rate difference between adjacent scale lines of the temperature rise rate detection scale is 10℃ / h.

[0053] Optionally, the scale lines of the heating rate detection scale and the holding time detection scale are numbered every four scale lines.

[0054] Specifically, since the distance between scale lines that differ by multiples of ten on the heating rate detection scale is relatively short, heating rate serial numbers are used to distinguish them. In addition, considering the high density of scale lines, every 5 scale lines are numbered. The heating rate detection scale is used in conjunction with the heating rate serial number correspondence table.

[0055] In one possible implementation, both the holding time detection scale and the heating rate detection scale are located below the heating rate sequence number correspondence table, with the holding time detection scale located to the left of the heating rate detection scale. Optionally, both the holding time detection scale and the heating rate detection scale are numbered to the right of the scale line.

[0056] Specifically, the information required for the test template includes: a holding time test scale, a heating rate test scale, and a heating rate sequence number correspondence table. These scales are added to the test template body. In this embodiment, the test template body is made to A4 size. The layout is determined based on the size of the test template body, the proportion of each type of information, and ease of testing. Both the holding time test scale and the heating rate test scale are located below the heating rate sequence number correspondence table, with the holding time test scale to the left of the heating rate test scale.

[0057] In one possible implementation, the line widths of the scale lines of the heat preservation time detection scale and the heating rate detection scale are both smaller than the line width of the heat treatment curve, the drawing deviation of the slope angle of the scale line of the heating rate detection scale is less than 0.007°, and the drawing deviation of the line length between adjacent scale lines of the heat preservation time detection scale is less than 0.01mm.

[0058] Optionally, the line width of the scale lines of the heat preservation time detection scale and the heating rate detection scale is 0.1 mm smaller than the line width of the heat treatment curve.

[0059] Specifically, the scale lines of the heat preservation time detection scale and the heating rate detection scale are drawn with thin solid lines with a width of 0.1mm, which are narrower than the heat treatment curve. The drawing deviation of the slope angle of the scale line of the heating rate detection scale is less than 0.007°, and the drawing deviation of the line length between adjacent scale lines of the heat preservation time detection scale is less than 0.01mm, so as to ensure the accuracy of the detection results of the precision of the manufactured test template scale.

[0060] In one possible implementation, the heat treatment curve recording parameter detection template is made in the following manner:

[0061] (1) Collect and organize technical data. Different specification parameters can be collected and organized based on the data from the heat treatment curve to determine the specifications of the heat treatment curve recording and testing template. Common specifications are: 1. Heat treatment curve with a horizontal temperature difference of 300℃, and paper feed rates of 50mm / h, 120mm / h, and 150mm / h respectively; 2. Heat treatment curve with a horizontal temperature difference of 600℃, and paper feed rates of 50mm / h, 120mm / h, and 150mm / h respectively. In this embodiment, the most commonly used heat treatment curve with a horizontal temperature difference of 300℃ and a paper feed rate of 150mm / h is selected as an example for the production of the heat treatment curve recording parameter testing template. Other specifications can be implemented with reference to this method.

[0062] By using the corresponding specifications and formulas, the curve length corresponding to one minute of the heat preservation time detection scale and the slope angle of each scale line of the heating rate detection scale are obtained under different specifications.

[0063] (2) Draw the heat preservation time detection scale and the heating rate detection scale.

[0064] The main parameters that need to be tested in the hot working curve are the holding time and the heating rate. Therefore, the main task of making the test template is to draw the holding time test scale and the heating rate test scale.

[0065] Heat preservation time test scale: For heat processing curves with a horizontal temperature difference of 300℃ and a paper feed rate of 150mm / h, the vertical length on the curve record corresponding to 1 minute of heat processing time is 2.5mm. The heat preservation time test scale is drawn with 2.5mm as one small grid, and the unit of the scale is min.

[0066] Heating rate detection scale: The maximum horizontal temperature difference of the heat treatment curve is 300℃, the small grid temperature difference is 3℃, and the horizontal length of the small grid is 2.5mm.

[0067] Based on the above, the angles of the slopes of the scales for heating rate detection scales with heating rates ranging from 270 to 700℃ / h and differing by 10℃ / h are shown in Table 1.

[0068] Table 1. Slant angles of each scale line on the heating rate detection scale.

[0069]

[0070]

[0071] The heating rate detection scale is drawn according to the slope angle of each scale line in Table 1. Since scale lines differing by 10℃ / h are close together, they are distinguished by serial numbers. Considering the high density of scale lines, every 5 scale lines are numbered. The heating rate detection scale is used in conjunction with the heating rate serial number correspondence table shown in Table 2.

[0074]

[0075] (3) Fabrication of a template ruler for recording parameters of hot working curve.

[0076] The information required for the heat treatment curve recording parameter test template includes: a holding time test scale, a heating rate test scale, and a heating rate sequence number correspondence table. This information is added to the test template body. The test template is made to A4 size, and the layout of each type of information is arranged according to the size of the test template body and for ease of testing.

[0077] The test template ruler body can be made of transparent plastic material with good permeability.

[0078] In another embodiment of the present invention, a method for detecting parameters of a heat treatment curve recording is provided, which can be implemented based on the above-mentioned heat treatment curve recording parameter detection template. Specifically, the method for detecting parameters of a heat treatment curve recording includes the following steps:

[0079] The heat preservation time testing procedure is as follows: Cover the heat preservation time testing scale of the test template ruler onto the heat preservation section of the heat treatment curve, align the 0 mark of the heat preservation time testing scale with the starting position of the heat preservation section curve, and read the scale of the heat preservation time testing scale corresponding to the ending position of the heat preservation section curve to obtain the heat preservation time of the heat treatment curve.

[0080] Quantitative detection steps for heating rate: Cover the heating rate detection scale onto the heating segment of the heat treatment curve, aligning the left boundary line of the heating rate detection scale with the temperature grid lines of the heat treatment curve. Read the serial number of the scale line that coincides with the heating segment curve to obtain the target heating rate serial number. Look up the heating rate serial number in the heating rate serial number correspondence table to obtain the heating rate of the heat treatment curve.

[0081] Qualitative testing steps for heating rate: Obtain the heating rate of the heat treatment curve, and refer to the heating rate sequence number correspondence table according to the heating rate of the heat treatment curve to obtain the target heating rate sequence number of the heat treatment curve; cover the heating rate detection scale onto the heating segment of the heat treatment curve, and align the left boundary line of the heating rate detection scale with the temperature grid line of the heat treatment curve, and determine whether the heating segment curve is within the scale line range corresponding to the target heating rate sequence number of the heat treatment curve. When the heating segment curve is within the scale line range corresponding to the target heating rate sequence number of the heat treatment curve, the heating rate of the heat treatment curve is qualified; otherwise, the heating rate of the heat treatment curve is unqualified.

[0082] For example, in a heat treatment curve with a transverse temperature difference of 300℃ and a paper feed rate of 150mm / h, the technical document requires a heating rate of 510~580℃ / h. Consulting the heating rate sequence number correspondence table, we find that the target heating rate sequence numbers for the corresponding heating rate detection scale are 25 and 32. Applying the heating rate detection scale to the heating segment of the heat treatment curve, the heating segment of the heat treatment curve falls within the range of the corresponding sequence number's diagonal line. Therefore, the heating rate of the heating segment of the heat treatment curve is qualified.

[0083] In summary, the hot working curve recording parameter detection template and detection method of this invention eliminate the need for calculations when detecting hot working curve recording parameters. Simply place the detection template over the corresponding position on the curve record, and the detection conclusion is obtained directly by comparing it with the curve. This reduces human intervention and solves the problems of wasted time and easy calculation errors in traditional curve recording detection processes. The use of this comparison template significantly improves inspection efficiency and ensures the accuracy and reliability of the detection results.

[0084] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of the claims of this invention.
