Bei Zhi * structure of the plate manufacturing method for the use of steel plate for the structure of the medium. A record that is inexpensive and has excellent mechanical characteristics [Embodiment] The following describes the present invention in detail. For example, the recording medium of the present invention is formed as shown in FIG. 1. The structure of the recording medium is to be formed for the first time CD users, and it is made into a type 4 box shape with the structure of the recording medium 2 to accommodate CD_ROM3 inside. The overall shape of the structure j of the recording medium Normally, a rotation drive C is formed on one of the two side portions 4, 4. The driving device and reading device (not shown) of the D-ROM 3 (not shown) ^ The recessed portion 5 for access is provided with other necessary shutters (shown), etc. Second, The steel plate for the architecture of the recording medium is explained. The composition of the steel plate for the architecture of the recording medium of the present invention is, by weight, c · 0.08 ~ 0.60%, Si: 2.0 ~ 3.0%, Μη: 0.5 ~ 3.0%, P: $ 〇 · 〇〇〇 / ο, s · < 〇〇6%, A1: $ 0.1%, N: 0.0010 ~ 0.0150%, the balance of Fe and unavoidable impurities formed. C factor is to make the recording medium The steel plate for architecture is added with a high degree of quenching and tempering, so it is preferably 0.08% by weight. On the other hand, if it exceeds 0.60% by weight, the amount of carbide precipitation will increase, which will cause the structure of the recording medium The workability of the steel sheet is reduced, and at the same time, it causes the deterioration of the shape of the cold rolled 1240006, which hinders the permeability of the steel sheet in the continuous annealing step, etc., and therefore, the upper limit of the C component is 0.60% by weight in the present invention.

When it is the same as C too much, it will become A board field (butter cracks, deterioration of shape, impediment to the continuous steel plate's permeability, etc., and lower productivity. Therefore, the upper limit is set to 30 weight. Refining the composition and increasing the strength of the steel plate used for the structure of the recording medium, it is clear that: ': 6, t added in the above example', but on the other hand, it will hinder the corrosion resistance. As for the hair demon t μ the right p exceeds °. When the resetting temperature is 65 ° C, the smartness, especially the resistance to digging, will be significantly reduced, so the upper limit is set to 0.06 wt.%. Cow ... If s is hot, the hot #L will generate red hot brittle impurities, It is better to reduce it as much as possible, but it can not stop at the origin of iron ore. It is also difficult to desulfurize in the process. There must be a residue of =. The red hot brittleness caused by a small amount of residue s, can be given by _ Subtraction: and the upper limit of the s component is set to 0. 06% by weight. 2. = At the time of steel making, it is treated with a deoxidizer. Add it to the steel bath, but if it becomes A1 in the heavy soil / JJ, it will be used as a mold powder towel to inhibit the oxidizing agent and to prevent the sintering and sticking agent from sticking when the casting is connected. Oxygen reacts and hinders the powder effect. Therefore, the amount of A1 is set to 0.10% by weight or less. N is the same as c and Mη, which gives a high degree of quenching and tempering to the steel plate for the structure of the recording medium. The required ingredients, but want to reduce to less than the weight percent of pay: = earning on steel production, and the other-more than 5Q weight added, will make wear ^ day: the yield of the added fabric is significantly reduced, lack of stability In addition, cracks are formed on the surface of the continuous casting sheet. Since t is a "defect," the N component of the present invention is set to be ~ 200% by weight. 0.0021 to 0.0150% by weight. 1 土 • The main characteristics of this I shape are A. Si is an element that has a large strengthening solid solution ability in steel towels and is effective in obtaining spring performance. Therefore, it must be above 2G% by weight. In addition, 1240006 More is better, but if it exceeds 3_〇 weight In this case, the load of cold rolling is increased, and the shape is deteriorated. Therefore, the upper limit is set to 3.0% by weight. The method of manufacturing the steel sheet for structural use according to the present invention is described below. Although the steel sheet heating temperature in the rolling step is not specified in the present invention, it is set to 1 丨 00 from the viewpoint of ensuring the 7% solid / valley of N and the stability of the hot rolling processing temperature. If the hot-rolling processing temperature is set to less than Ar3, the crystal structure of the hot-rolled steel strip will be mixed and granulated, and at the same time coarsened, but the intended strength cannot be obtained. Therefore, the hot-rolling processing temperature is set to Ar3. The above point is better. The coiling temperature is set to 450. (: ~ 650.) Considering the quality stability in the width direction and length direction of the coil during hot rolling, the lower limit is 450 ° C. If the coiling temperature exceeds 65 ° t, the crystal grain size will increase during hot rolling and continuous annealing. When the structure of the recording medium is processed, it becomes a bad cause, so the coiling temperature is set to 65 ( The following rc is preferred. Although the hot-rolled steel sheet having the above-mentioned composition system is pickled, it is cold-rolled, but the cold-rolling ratio and composition are both important strength factors of the present invention. It is carried out at 50 ~ 90%. As mentioned above, 50 ~ 90% of cold-rolled material has been applied, and it is subjected to degreasing plant treatment in the cleaning step, at 630 ~ 870 C, preferably 680 ~ 87〇t: Continuous annealing. Or batch annealing at 5⑻ ~ 75 ° C, preferably 600 ~ 750 ° C. If the annealing time can be within the range of pre-recrystallization, the rolling rate is 7% after annealing. The following secondary rolling or temper rolling is required. After that, it is necessary to provide surface roughness by temper rolling. Although the thickness of the plate is not specified, it is preferably from 0.1 mm to 0.5 mm. It is preferable that it is within the range of 0.2 to 0.35 mm. Next, as for the steel plate for the structure of the recording medium of the present invention thus produced, Examples include plate-shaped and coil-shaped steel plates, steel boxes, and those who have surface-treated these steel plates. In particular, nickel plating, galvanization, composite galvanized zinc_molybdenum, galvanized nickel alloy, and galvanized iron alloy , Molten zinc plating, molten zinc-aluminum alloy plating, and chemical treatment of these electroplating are excellent in terms of corrosion resistance. Chemical treatment can be applied to well-known ones, such as chromate treatment, phosphoric acid, etc. Salt treatment, electrolytic vanadium treatment, silicate treatment, or lithium silicate treatment. | 1240006 Examples As far as the examples and comparative examples of the present invention are concerned, Table 1 shows manufacturing conditions such as steel composition and rolling rate, and Table 2 shows Results of evaluation of characteristics. In Table 丨, those who did not perform secondary rolling and indicated “the surface roughness (represented by Ra in accordance with JXS b 0102 regulations) by surface rolling is 0-8 // m. Sample No. 1 ~ 2, 5 ~ 10 are applied with zinc-0.5% by weight and 0.01% by weight molybdenum composite electroplating (mine zinc content: 15g / m2) to plate thickness 0.3 mm, and then treated with complex acid to chromium (Cr) adhesion amount is 38 mg / m2. Sample Nos. 3 to 4, 11 to 14 are applied to the plate thickness of 0.2 mm -0.5% by weight cobalt_〇.〇1 weight! ^ After molybdenum composite plating (plating amount: 10 g / m2), electrolytic vanadium treatment was applied until the adhesion amount in terms of vanadium (ν) was 70 mg / m2. Table 2 It means that samples with a tensile strength (TS) of 500 MPa or more and an elongation (T.EL) of 15% or more are good, and the comprehensive evaluation is indicated by 0. From Tables 1 and 2, it can be seen that the samples of the examples Number 11 is superior in tensile strength and elongation, and can be used for the structural use of recording media. On the other hand, sample numbers 5 to 6, 10 are not strong enough due to the small tensile strength, and sample numbers 7 to 9 and 11 to 14 have a small elongation and are inferior in processability.
