は見当らない。In recent years, demands on steel sheets for workability and drawability have increased, and in order to meet these demands, steel sheet manufacturers conduct various material tests and commercialize products that meet the requirements. By the way, the above-mentioned material tests include tensile tests, formability tests, etc., and generally "value (Lankford)
, CCV (conical cup test value), EJ2 (total elongation), and YP (yield point) are measured as indicators of workability and drawability. In addition, it is known that the crystal texture has a good correlation with these material values, especially the r value, and in order to evaluate workability and drawability, it has been conventionally known that the crystal texture and r [
Research is being conducted regarding this. Methods for investigating this texture include general measurement methods using X-rays, and in recent years,
A measurement method using ultrasound has been developed as proposed in . However, in order to perform these 44'R tests on steel plates passing through a steel plate manufacturing line, it is necessary to temporarily stop the line and perform sample collection and testing by a large number of operators. Therefore, there are problems in that it is inefficient and unproductive, and also increases labor costs. Therefore, as a method of adjusting the texture of a steel sheet without stopping the production line, a method using parallel beam characteristic X-rays has been proposed in Japanese Patent Application Laid-Open No. 77250/1983. [Problem 1 that the invention seeks to solve: However, using the above-mentioned X-rays! Since this method detects diffracted X-rays, the surface of the steel sheet must be flat, and even on a flat surface, there is a problem that measurement is impossible if the steel sheet is being photographed during passing. Furthermore, if cooling water or rolling oil adheres to the steel plate, there is a problem that the attenuation rate of X-rays becomes large and measurement becomes impossible. Therefore, due to these problems, there are no examples of this method being used in actual production.

集合組織の変化を定量化できるものである。The present invention was created by researching the magnetism of steel sheets using the electromagnetic induction method and discovering that the induced electromotive force changes as the texture of the steel sheet changes. First, the present invention will be explained (experimental results obtained).The present inventors prepared cold rolled sheets annealed at various soaking temperatures as shown in Table 1, and As shown in the figure, the induced electromotive force was measured by electromagnetic induction. When an alternating current magnetic field is applied to the sample 1 by generating an alternating current magnetic field at 1 A and 2, the magnetic flux passing through the sample 1 is determined as an induced electromotive force by N magnetic induction using a detection device I!3 consisting of a coil located at the bottom of the sample 1. Figure 3 shows the relationship between induced electromotive force E and annealing soaking temperature T measured using this experimental equipment, with induced electromotive force E on the vertical axis and annealing soaking temperature T on the horizontal axis. This diagram is not shown as a graph.As shown in Fig. 3, as the soaking temperature T increases, the induced electromotive force E decreases.
It was found that it reaches a minimum value at about 800°C and increases thereafter. On the other hand, the texture of the same sample was investigated by XWA diffraction method. Fig. 4 is a diagram showing the relationship between the X-ray diffraction intensity I of the Miller index display (222) plane and the soaking temperature T, with the xi diffraction intensity 1 on the vertical axis and the lower annealing soaking temperature on the *@. Shown as From FIG. 4, it was found that the diffraction intensity I increased as the temperature T increased by an average of 1.1%, and this relationship also showed a maximum value at 800° C., similar to the above. Therefore, when we investigated the relationship between the induced NftE and the X-ray diffraction intensity, we found that there was a one-to-one correspondence as shown in FIG. Such a result is [22
2) This is thought to be due to the fact that the development of surface texture reduces the magnetic properties of the steel sheet, particularly the magnetic permeability, making it difficult for magnetic flux to pass through and reducing the induced electromotive force. Therefore, by applying an alternating am field to the steel plate, detecting the amount of magnetic flux passing through the steel plate, and measuring the induced electromotive force,
It is possible to quantify changes in texture.

いても使用可能であり、汎用性に優れる。Example 1 An example of the present invention will be described in detail below with reference to one drawing. Steel plate manufacturing line to which the embodiment of the present invention is applied
j Shear line is uncoiler 2 as shown in Figure 6.
0, a processor roll 22, a trimmer 24, a skin bath mill 26, a leveler 28, a shear 30, and a steel plate 10
After the shape is corrected through these devices, it is cut into predetermined dimensions. Between the leveler 28 and shear 130 of the shear line constructed in this way, there is a device 11 that applies an alternating magnetic field to the steel sheet 1o and measures changes in the amount of magnetic flux generated from the steel sheet, that is, a steel sheet texture development degree measuring device 11. to be placed. This texture development degree measuring device 11 has the same configuration as the experimental device described above, as shown in FIG. 7, for example. That is, when an alternating current magnetic field is applied to the steel plate 10 by the alternating current magnetic field generator 12, which is an excitation coil disposed below the pass line of the steel plate 10, the magnetic flux passing through the steel plate 10 is caused by the coil disposed below the pass line of the steel plate 10. The electromotive force is determined as an induced electromotive force by electromagnetic induction in the detection @@14, and this electromotive force is expressed as the X-ray diffraction intensity related to the mirror index display (222) in the steel plate 10.
A computer measures changes in the amount of magnetic flux generated from the steel plate 10 obtained by applying an alternating magnetic field to the steel plate 10, and stores in advance the measurement results regarding the (222) plane and the changes in the amount of magnetic flux. The XS+ diffraction intensity measurement result corresponding to this electromotive force is processed by an arithmetic unit 16, and is selectively outputted as information regarding the (222) shape of the steel plate. In addition, 13 in FIG. 7 indicates an AC excitation device, and the measurement results measured using this measuring device 11 are expressed as mm8.
As shown in the figure. This measurement result was obtained as a continuous change in the induced electromotive force E over the entire longitudinal direction of the steel plate 10. The part where the induced electromotive force E is high in Fig. 8 is the part where the texture of the Miller index (2223 plane) is not sufficiently developed and the workability is poor.The broken line in Fig. 8 indicates the product tolerance range. This fracture 1g indicates the induced electromotive force E and the part 1 determines the material that can be used as a product. Conventionally, when investigating the texture of the steel plate 10, the production line is The conventional method was stopped and a sample was taken at position A-E in Fig. 8.Next, based on this detection result, the part that did not fall within the product tolerance was cut off using a shear.Therefore, this conventional method As a result of locally measuring the texture of the steel sheet, it is found that positions A and E shown in Figure 8 are outside the product tolerance range, but on the other hand, the It is not possible to detect the part outside the product tolerance range of 1ffF as shown in Fig. 8.Therefore, in the conventional method, the above WIF part is also turned into a product.According to the present invention, the steel plate 10 Since information on the degree of development of the texture in the steel sheet can be obtained continuously over the entire longitudinal direction of the steel sheet, the above-mentioned conventional disadvantages can be solved and only the parts of the steel sheet that are within the product tolerance range can be reliably manufactured. Although the present embodiment describes the case where it is adopted in a shear line, it is not limited to this, and it can be used in places where cooling water or rolling oil is used, such as in a hot cooling zone or a tandem mill. Alternatively, it can also be applied in high-temperature locations such as in a continuous annealing furnace.In addition, in this example, the induced electromotive force measuring device was configured with two coils, an excitation coil and a detection coil. but,
For example, without being limited to this, the induced electromotive force is affected by the distance between the coil and the steel plate, so in order to eliminate this effect, one excitation coil and two detection coils are connected to each other. The measurement device may be configured to eliminate the influence of the measurement distance by arranging the distances of the detection tiles to be different and determining the ratio of the electromotive forces induced in the respective detection tiles. [Effects of the Invention] As explained above, according to the present invention, the following effects can be obtained. (1) Information on the texture of a steel plate can be obtained non-destructively and at low cost. (2) Information on the texture of the TS plate can be obtained instantly. (3) By installing it on the $1 plate production line, it is possible to obtain information on the continuous texture of the steel plate throughout the longitudinal direction without stopping the line. Therefore, the portion of the steel plate that is outside the product tolerance range can be reliably detected, the portion outside the product tolerance range will not be made into a product, and the reliability of the product can be improved. (4) It can be used in places where cold pepper water or rolling oil is used, or in places with high temperatures, and is highly versatile.
