の圧延エネルギー及び加熱エネルギーを要する。The most common method for manufacturing thin metal sheets, and still in use today, is to cast a thick slab using a continuous slab casting machine and roll it 5 to 10 times or more on a separate hot rolling line. It is thinned and wound up using a winder to form a hot coil, and then passed through a cold rolling line to form a final product as a cold rolled material. However, this method requires many rolling steps and a huge amount of rolling equipment, which increases equipment costs.Also, it is necessary to heat the slab and control it at a constant temperature, so it requires a large amount of rolling. Requires energy and heating energy.
このような背景の下に、近年、溶湯より直接金属薄板を

うにした薄板連続製造設備が提案されるに至った。Against this background, in recent years, twin-roll, belt-type, or caterpillar-type continuous sheet casting machines have been developed that can cast thin metal sheets directly from molten metal, and the sheets cast from these casting machines can be cast online. A continuous thin plate manufacturing facility has been proposed that allows rolling and finishing of thin sheets to a predetermined thickness.

置した構成を有する。The present invention provides continuous thin plate manufacturing equipment in which a plate material cast from a continuous plate casting machine is cooled by a cooling device and then rolled by a cold rolling machine installed online.
A non-oxidizing chamber in which N2 gas or the like is blown is formed to surround the line of the plate material between the casting machine and the cooling device, and a hot rolling device for light reduction is installed at an appropriate position within the non-oxidizing chamber. It has a configuration in which

きとしである。A cooling device (5) located upstream of the rolling mill (2) for cooling the plate material (4) cast from the casting machine (1) with a roller at a temperature (normal temperature) suitable for rolling in the rolling mill (2). A plate material (4) is provided between the cooling device (5) and the outlet of the casting machine (1).
A blocking duct (6) is arranged to surround the line, and an inert gas supply is provided to the duct (6) for supplying an inert gas such as N2, Ar, He, etc. into the duct (6). A device (7) is connected to form an oxidation-free chamber in the duct (6), and a cooling device (7) in the duct (6).
