We toured the facilities of JFE Engineering Tsurumi Seisakusho, which is located on the coast of the Keihin Industrial District. JFE Engineering's business is mainly engineering work such as planning and procurement of plants such as steel structures and waste treatment facilities. is a factory with a long history that manufactures and repairs shield machines, steam turbines, and marine engines.On the other hand, in recent years, the factory has also been working on the latest systems that consider energy conservation and the environment, such as the pursuit of new manufacturing equipment using 1912D printers, the development of biomass power generation systems, and smart agriculture that effectively utilizes exhaust heat and CO2. was
The inside of the factory is fully equipped with production equipment such as cranes, and the factory building is over 600m from north to south.It is an overwhelming scale that you do not usually see.Inside the building, the production areas were divided for each process, such as welding, machining, and assembly.
Regarding shield machines, multiple shield machines are produced simultaneously from the machining process to the trial run process for domestic government offices and Southeast Asia where infrastructure construction is booming, and I was able to learn about the internal structure and operation method.
In the case of steam turbines, even though they are only a few megawatts in size, I saw firsthand the need for precision machining such as wire-cut electric discharge machines and technology to assemble them with a clearance of several hundred micrometers.In particular, the rotors of multi-stage steam turbines have rotation speeds exceeding 10,000 rpm. I understood that setting and assembly skills are necessary to realize it.
In the case of marine diesel engines, we got a glimpse of the difficulties and ingenuity involved in manufacturing and assembling cylinder blocks for 9,000-horsepower, 12-cylinder engines, as well as test run methods that take environmental regulations into account, and mass production of large products.
As described above, we were able to learn about the important heavy industrial products and their production processes that are used to realize the infrastructure that we take for granted, although we do not often see them in our daily lives.
I would like to express my sincere gratitude to Mr. Sagara and Mr. Ban of JFE Engineering Co., Ltd. for guiding us, and to Mr. Minami for setting up a facility tour for JSPE members.
