Benefits of technology
The production method in this patent makes it easy to make a metal sheet with raised lines on both sides. This metal sheet can be used to make a reinforced structural component, where the entire area is strengthened. This makes the metal sheet ideal for use as a material for a part-reinforced structural component.
Problems solved by technology
Accordingly, a welding process must be separately carried out to partly reinforce the structural component 20, which results in an increase in manufacturing cost.

Embodiment Construction
[0043]Some embodiments of the present invention will hereinafter be described with reference to the drawings.
[Producing of Metal Sheet with Raised Lines]
[0044]FIG. 2 is a schematic diagram of an example of a production facility used for the production of a metal sheet with raised lines according to an embodiment of the present invention. The present embodiment describes the production of a steel sheet 10 with raised lines as an example of the production of a metal sheet with raised lines. Specifically, in the following, the production of a metal sheet with raised lines with a steel slab 30 used as a material for the metal sheet with raised lines will be described.
[0045]The production facility illustrated in FIG. 2 includes a heating furnace 1, a rough-rolling mill 2, a finish-rolling mill 3, a cooling device 4, and a coiler 5 that are arranged in this order. The heating furnace 1 heats the slab 30. The heated slab 30 is first fed to the rough-rolling mill 2. The rough-rolling mill 2...

Abstract
A method for producing a metal sheet with raised lines uses a rolling mill including a roll stand and produces a metal sheet including, on each of an upper surface and a lower surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, an incorporating step, and a forming step. In the preparing step, grooved rolls are prepared, each of the grooved rolls including a plurality of grooves in an outer peripheral surface. In the incorporating step, the grooved rolls are incorporated in the roll stand as an upper roll and a lower roll, respectively. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved rolls.
Description
TECHNICAL FIELD[0001]The present invention relates to a metal sheet such as a steel sheet suited to be used in structural components of automobiles, various kinds of vehicles other than automobiles, home appliances, vessels, construction materials and so on. In particular, the present invention relates to a metal sheet including, on each of the upper surface and the lower surface, one or more raised lines extending in the rolling direction, a method for producing the metal sheet with raised lines, and a structural component produced by use of the metal sheet with raised lines.BACKGROUND ART[0002]Pressed parts are used in general structural components. The material of a pressed part is a metal sheet such as a steel sheet. A structural component is formed from a single pressed part or formed by joining a plurality of pressed parts. For example, the structural components for automobiles disclosed in Japanese Patent Application Publication No. 2013-189173 (Patent Literature 1) and Japan...
