For example, building materials such as a roof plate, a wall plate, and a deck plate formed by roll-forming colored tin and galvanized steel sheets, and home electric appliances such as a refrigerator body formed by roll-forming pre-painted steel sheets are well known. Since roll-formed products using these surface-treated steel sheets are thin and wide products, various problems are likely to occur during the forming. For example, "Plasticity and processing" vol.20, (1979)
225, P933 and "Plasticity and Processing", vol. 23, (1982) 259, P779, describe the occurrence and countermeasures such as pocket waves, edge waves, and waist breaks as defective phenomena in roll forming.

る。[0003] The pocket wave is a phenomenon in which a plastic shrinkage in the longitudinal direction remains in a flange portion or a corner portion formed by roll forming, and a surplus length escapes to generate loose irregularities in a central flat portion. It is effective to make the yield point of the material sufficiently high so that all deformation during molding is within elastic deformation, and it is said that it is difficult to occur when the yield elongation is large. Regarding the influence of the leveler, it is possible to increase the flatness of the base material, but on the contrary, the yield point is greatly reduced, so that pocket waves are likely to occur, which is considered to be negative.

As a countermeasure, it is most effective to reduce the yield elongation by applying a leveler or the like. ing. The edge wave is a phenomenon in which an outer flat portion of a steel sheet roll-formed into a mountain cross section expands and contracts and undulates. As a countermeasure, it is preferable to increase the yield point of the material.

トに用いれば床面の衝撃音を大幅に緩和できる。On the other hand, recently, as a material of a roll forming plate such as a shutter material, a roof plate, a deck plate and the like, an attempt has been made to use a damping steel plate instead of the above-mentioned general steel plate. Vibration-damping steel sheets made of two steel sheets as original sheets and laminated in a sandwich by bonding the original sheets together with an adhesive cause shear deformation of the viscoelastic adhesive when bending vibration is applied, converting vibration energy into thermal energy Therefore, it has a great vibration and soundproof effect. The shutter material roll-formed from this damping steel plate has less noise when opening and closing,
Roofing can reduce the sound of rain, and if used on the deck plate of a gymnasium, can significantly reduce the impact sound of the floor.

の鋼材の使用等が有効とされている。The roll formability of the damping steel sheet having such advantages is described in, for example, "Plasticity and Working" vol. 30, (1989).
347, P1618 states that shape defects such as bending of a flange and peeling are likely to occur during molding. Flange bending is caused by the shear force generated in the process of generation and elimination of the longitudinal deviation of the front and back steel sheets seen during roll forming and the compressive shear force generated by bending of the sheet. Prevention of longitudinal displacement of the steel sheet, use of a steel material having a low yield point, and the like are effective.

トウエーブが発生し易くなる。However, in order to improve the roll formability of the damping steel sheet, when a steel sheet having a low yield point is simply used as the original sheet, the bending is improved but the pocket wave and the edge wave are opposite. Easily occur.
In order to suppress the occurrence of the pocket wave, it is conceivable to use a steel plate having a large yield elongation, but in this case, the flange is likely to break. If the yield elongation is reduced by using a leveler as a countermeasure against the buckling, a pocket wave is likely to occur.

The present invention is intended to solve such contradictory and contradictory problems, and it is difficult to bend or peel off and to obtain a roll formed product having good dimensional and shape precision, which is a vibration control for roll forming. It is an object to provide a steel sheet and a method for manufacturing the same.

て本発明をなすに至った。The inventors of the present invention have conducted intensive studies on vibration-damping steel sheets having good roll formability, for unknown reasons. As long as the yield ratio (YR) in the direction (YR) is 90% or more and the yield elongation (YEl) satisfies the condition of 5% or more, the characteristic value in the longitudinal direction (hereinafter referred to as L direction) is not specified, The present invention has been found to be able to effectively prevent the occurrence of pocket waves and edge waves during roll forming, and to prevent defects in size, shape, and adhesion from occurring in roll-formed products.

な条件を満たすことが必要である。Here, when the yield ratio in the C direction is less than 90%, pocket waves and edge waves occur. If the yield elongation in the C direction is less than 5%, the springback of the roll forming is too large, and the dimensional and shape accuracy of the product is poor. Also, peeling is likely to occur at the end of the molded product. In manufacturing the damping steel sheet for roll forming of the present invention, the following conditions must be satisfied in order to secure the mechanical properties in the C direction of the damping steel sheet within the above range.

なった。In producing the original sheet for damping steel sheet of the present invention, the steel sheet annealed after cold rolling is not subjected to temper rolling, but is subjected to tension and repeated bending only by a tension leveler. Apply shape correction. When temper rolling is performed in the production of a master sheet, the yield point and the yield elongation in the L direction and the C direction decrease below desirable limits. On the other hand, when the shape was corrected using only the tension leveler, the yield point and the yield elongation in the C direction were small, and the yield ratio was 90% or more and 5%.
Experiments have revealed that a yield elongation of at least 10% can be obtained.

この点からも、本発明にあっては原板の製造時に調質圧
延を行わないことが条件の一つといえる。The original sheet serving as the skin material of the damping steel sheet of the present invention is not limited to a cold-rolled steel sheet or a surface-treated steel sheet. But,
For example, it is desired to cope with a material used in applications where a complicated bending process is repeatedly performed, such as a damping steel plate for a shutter material, since the end portion is easily peeled off during the bending process.
In that case, an alloyed hot-dip galvanized steel sheet is particularly preferable.
The reason for this is that the alloyed hot-dip galvanized steel sheet has a large surface roughness when not temper-rolled, and particularly has a large PPI (peak per inch) value of 400. This is because an extremely large adhesive force can be secured as a result of promoting the adhesive effect. By the way, when the temper rolling is performed, the value of PPI is halved to 200, and accordingly, the anchoring action of the adhesive is sharply reduced.
From this point, it can be said that one of the conditions in the present invention is that temper rolling is not performed during the production of the original sheet.

When the base plate of the damping steel sheet is bonded with an adhesive, it receives a heat history of 180 to 200 ° C., and when a large amount of N is contained as much as 50 ppm or more, aging due to the heat causes the obtained damping steel sheet to This is because the yield point becomes high, and the yield ratio of 90% or more and the yield elongation of 5% or more are easily achieved. An amount of N exceeding 200 ppm causes a problem in brittleness.

There is No. 59.

It is excellent and has excellent adhesive performance required during molding, and also has extremely high performance in adhesive stability and durability at high temperatures after molding. By using this in the adhesive of the present invention, a vibration-damping steel sheet for roll forming having high damping properties and adhesive strength and having no end surface peeling can be easily obtained.

Each steel material having the composition shown in Table 1 was hot-rolled as usual, pickled and then cold-rolled to produce three types of wide-width steel sheets having a thickness of 0.3 mm. These steel sheets were sent to a hot-dip galvanizing line to produce hot-dip galvanized steel sheets to be used as base sheets for damping steel sheets. In the original plate manufacturing process, the product of the present invention was subjected to shape correction using only a tension leveler, and was not subjected to skin pass by a temper rolling mill. On the other hand, comparative products 1,
For Comparative Product 2, a 1.5% skin pass by a temper rolling mill and a tension leveler were used in combination. Subsequently, three types of damping steel plates were manufactured using these three types of steel plates as original plates by a damping steel plate manufacturing line. As the adhesive for the damping steel sheet, a thermosetting polyester resin to which Ni particles for imparting conductivity were added was used, and the resin coating thickness was 25 μm.

られるという効果を奏する。As described above, according to the present invention,
The steel sheet annealed after the cold rolling is passed through a tension leveler without passing through a temper rolling step, and the steel sheet whose shape has been corrected is used as an original sheet. The yield ratio in the width direction (C direction) of roll forming is 90. and yield elongation at least% was assumed to achieve 5% or more roll forming damping steel plate. Therefore, the roll forming of the damping steel plate, which has been difficult in the past, becomes easy, and as a result, the vibration damping and soundproofing properties are high, the bending and the peeling are hard to occur, and the dimensions and the shape accuracy are good.
This has the effect that roll-formed products such as roofs, walls, and curtain rails can be easily obtained.
