Description of the Related Art For example, in order to manufacture a so-called composite steel plate such as a vibration-damping steel plate or a light-weight steel plate in which two steel plates (skin materials) are laminated with a synthetic resin, first, a material for a skin material is cold-rolled respectively. A method is adopted in which a predetermined plate thickness is obtained, and thereafter, annealing or annealing and plating are performed if necessary, and the obtained skin material is laminated with a synthetic resin to form a composite steel sheet. Although the relationship between the plate thickness and the plate width of the rolled steel plate depends on the rolling equipment, the allowable limit of the plate width that can be manufactured becomes smaller as the plate thickness becomes thinner. With conventional general cold rolling equipment, it is not possible to roll wide and thin coils, and the limits are 5 strips or less for strip width and 0.4 for strip thickness.

できないという問題点があった。Recently, composite steel sheets such as vibration-damping steel sheets and lightweight steel sheets have been focused on their noise reduction and weight-reducing functions, for example, automobile roofs, bonnets, floors, railway vehicles, etc. There is an increasing demand for application to wide parts. However, for that purpose, a steel plate having a plate thickness of less than 0.4 mm and a plate width of 5 shank or more is required as a skin material, and there has been a problem that it is not possible to meet the needs in the past due to facility restrictions.

済である。In the method of manufacturing a wide and thin steel sheet material of the present invention, lap rolling is performed at all rolling stages from hot rolling to cold rolling. During hot rolling, two slabs are piled up and down. 1 to 3 show a slab overlapping method according to the present invention. First, a surface 1 of a lower slab 1 on the overlapping side.
A is scraped off by means such as surface grinding, leaving the peripheral portion, to form a recess 1b (FIG. 1 is a sectional view perpendicular to the longitudinal direction). The cutting allowance a depends on the size of the slab, etc., but is 0.05.
~ 5 mm. If it is less than 0.05 mm, the stripping agent required for separating the strips described later cannot be put in, and the stripping agent is insufficient, which hinders the separation. On the other hand, if it exceeds 5 mm, it is uneconomical because an excessively large amount of release agent is required.

If it is less than 3 mm, the upper and lower joining forces will be insufficient during hot rolling or cold rolling, resulting in separation. Further, since the joint surface is not finally removed and becomes a product, the material is wasted if the joint surface exceeds 200 mm. In addition,
It is desirable to grind the entire joint surface in order to remove the oxide film when forming the slab and promote the joint.

に応じてアーク溶接等により溶接する（図３）。The stripping agent 3 is supplied to the scraped recess 1b of the lower slab 1. As the release agent, oxide powder such as MgO or SiO 2 having a high melting point and stable at high temperature is preferable. The supply amount is preferably such that the concave portion 1b is just filled, and is sprayed evenly. After that, the upper slab 2 is superposed on the surface of the lower slab 1 on the superposing side (FIG. 2). At least a part of the boundary portions 4 on the four sides of the upper and lower slabs that are overlapped is welded by arc welding or the like, if necessary (FIG. 3).

Solid diffusion occurs at the portion of the joining surface 1a of the slab 5 that is overlapped, and the upper and lower slabs 1 and 2 are joined. After that, the superposed slab 5 is subjected to rough rolling, hot rolling, and cold rolling in sequence according to a normal rolling process using a normal rolling facility to obtain a predetermined plate thickness. In all of these rolling steps, a stack of two sheets is rolled as one sheet. In other words, this corresponds to rolling at a plate thickness twice as large as the plate thickness in normal single rolling, and the plate width limit at which rolling is possible is expanded accordingly, and wide width rolling becomes possible.

At this point, the double strip is separated into two single strips, and the release agent is removed. However, the release agent has a rust preventive function and can be used as a product as it is.
Alternatively, when the surface of the composite steel sheet is suitable for adhesion, it is not always necessary to remove the release agent.

From the double strip rolled to a wide width with a thickness of tmm, a strip made of a single steel plate with a thickness of 1/2 tmm and having the same width can be obtained, and can be used as a wide and thin steel sheet material 9 for various purposes.

樹脂を介して接合する。According to the method for producing a wide and thin steel plate material of the present invention, a conventional rolling equipment is used, and conventionally, for example, the plate thickness is 0.2 mm.
In the case where only a raw material product with a maximum plate width of 1000 mm was obtained, a product with a plate width of 1700 mm can be obtained.
In the method for manufacturing a composite steel sheet according to the present invention, the material 9 for wide and thin steel sheet is used as a skin material. Then, in the same manner as in the normal composite steel plate manufacturing process, the two skin materials are joined via a synthetic resin.

It is advisable to bond the surfaces that are left as they are to each other through a synthetic resin. The reason is that the surface rolled in contact with the release agent has unevenness due to the biting of the release agent particles, which increases the surface roughness, which increases the bonding strength with the resin film and increases the peel strength. This is because a steel plate can be obtained.

Therefore, it is possible to meet the needs of the market by providing composite steel sheets for wide parts such as automobile roofs, hoods, floors, etc., which could not be applied conventionally.

る。The wide thin steel sheet material obtained by the present invention is not necessarily limited to a wide composite steel sheet, but can be applied to other uses. Furthermore, if multiple strips of thin steel sheet material or composite steel sheet having a narrow width are taken from a single wide-width thin steel sheet material coil or wide-width composite steel sheet coil, there is an advantage that each product can be provided at a lower cost than when it is manufactured narrowly from the beginning. ..

場ニーズに応えることができるという効果が得られる。As described above, according to the method for producing a wide and thin steel sheet material of the present invention, the slab is subjected to the lap rolling from the stage of hot rolling, so that the conventional limit can be obtained by using the conventional rolling equipment. It is possible to obtain an effect that a wide and thin steel plate having a width of more than 5 can be manufactured at low cost. Further, according to the method for producing a composite steel sheet of the present invention, since the wide thin steel sheet material produced by the method for producing the wide thin steel sheet material is used as a skin material, it provides a wide and thin composite steel sheet which has not been available in the past. It is possible to meet the needs of the market.
