NIPPON STEEL CORPORATION x PIGMENT TOKYO - Exploring Nippon Steel Corporation East Nippon Works Naoetsu Area, a hub of the world's finest technology and manufacturing -②

As I mentioned in the first part, Pigment Tokyo is in collaboration with Nippon Steel Made in Corporation, which pursues the power of the world's finest technology, and for painting for painting using the company's design titanium Titanium Titanium Titanium. The base material has been released.

Design Titanium Titanium TrantixXII® Series requires a variety of processes, from the purification and casting of raw materials to special surface finals such as polishing. The core of the process is Niigata Prefecture, Nippon Steel Made in Joetsu City.

Located in the center of the Hokuriku region, it has been a key point of transportation since ancient times, and has created historical figures such as Kenshin Uesugi. In addition, it is known in one of the world's leading snowfall areas surrounded by steep mountains and steep mountains, and due to the abundant power of hydroelectric power generation using snow from the mountains. It is also a prosperous town. The Naoetsu area has also developed as a core base of the world's unique luxury material dungeon Titan Titan Titanium Titan Titan Titanium Titanium Titanium, which is the source of stainless steel manufacturing using electricity.

The Sea of ​​Japan is right next to the factory. The snow is blowing sideways due to the sea breeze!



In order to approach the site where the product grown in such a heavy snowfall area is manufactured, we have specially covered this time. It is the first time that an interview camera has entered the factory. Let's get close to the secrets of the hidden titanium.


First of all, Kazuhiro Arai, General Manager of the East Nippon Steel Maker Maker Maker Maker Milling Co., Ltd., Titan Management Office, explained the process until titanium was formed.




It seems that the design titanium handled by Pigment Tokyo this time is manufactured by the following processes.


extraction

Extract titanium metal from sandy ore to manufacture stone lumps (sponge chitan)

② Missing

Titanium dissolves using sponge titanium to generate a huge titanium mass (ingot)

③ Characteristics

Forged the ingot and divided the lumps to adjust the size and shape (hidden body) (slab) suitable for the next step.

④ Heat rolling

By softening the titanium under a high heat and extending it with pressure, a thin titanium plate with a roll -shaped (scroll shape like a toilet paper) is used.

⑤ Cold rolling

By applying pressure at room temperature and extending, it is a thinner and precise roll -like titanium plate.

⑥ Design

Create textures by titanium color development and special processing by oxide film, etc.


Instead of all of these factories, the process is shared by Japanese steelmaking companies and related companies all over Japan, and high -quality products have been created by close cooperation and construction. 。


Among this process, the Naoetsu area, the core base, is responsible for the main process of (2) ③⑤, and plays the role of the command tower to the process of ①④⑥ outside the district.

Let's take a look at the site where titanium is actually born.


First, the drums with sponge chitan, which are lined up in the factory. The freshly extracted sponge chitan (shape before the shape is adjusted in a stone -shaped shape) is an irregular form as if it was foamed. It's like an abstract sculpture.

The sponge chitan in the drum can be finely crushed, and is solidified in the form according to the melting process, creating a giant sponge chitan grain.

Then, put the crop into a huge electric kettle. After dissolving, a cylindrical titanium lump is created called ingot.

Next, the ingot is to the ③ duty process. Here, the process of extending a thin extension after ④ is forged with a huge machine (tapping and deforming the shape), and it is set to a rectangular shape of about 1.5 m in diameter called a slab of a lid. 。

After cooling, the slab is sent to the thermal rolling process, which is responsible for another base.

By sandwiching the huge hot -rolling process of the steelmaking station where steel is made, it is returned to the Naoetsu area in a roll -shaped shape, leading to ⑤ cold rolling process.

Unlike the heating process, the cold rolling process is used to use a huge roller at room temperature and extend it over and over again until the roll -like titanium is required by the client. It seems that 20 rollers are combined up and down. The main thickness of the titanium panel handled in Pigment this time is 0.3mm.


Eventually, a special surface processing is applied to adjust the color and texture in the design process, and TrantixXII® is completed.


This time, as a control tower of the manufacturing of the series, Kohei Nishiwaki and Kohei Fujita, the technical department of the Naoetsu area, who are involved in planning and research, have been created by repeated trial and error and research. I showed you the color sample.

Titans with a wide variety of expressions, made by various manufacturing conditions and secret recipes, which could be said to be the result of the accumulation so far, were filed, and the variation was overwhelmed by the spread of its variations.

From the fine color gradation to the complex texture, there is a rich design that does not seem to be the same titanium.


This time, while covering Nippon Steel Made in Corporation and Naoetsu area, I felt that many people were really involved in this titanium business.

Please try the painting base material using the world -class design, Titan Titan Titanium, which is carefully created in the Naoetsu area, the world's finest technology and manufacturing area.
