"Coke" is an indispensable reduction material when processing iron from iron ore.
We have stably supplied high quality coke which in blast furnace is the "starting point" of various industries.
In our coke business, we aim to become a strong business entity that is not swayed by variations in the market.
Our Kitakyushu Coking Works is one of the best coke production bases in Japan (annual production capacity 2.1 million tons), and controls all processes, from receiving to production and shipment, through automation. It strives for automated, streamlined, and highly efficient operations, supplying coke for blast furnaces and foundry that is unrivaled in quality.
We have many years of accrued experience in material mixing and firing technology and an outstanding reputation within the market. We export to overseas blast furnace manufacturers, as well as to manufacturers in Japan.
Furthermore, in order to establish a "strong business entity" we actively promote reduced production costs and improved manufacturing technologies.
In our coke production, generated gases are converted to clean energy, then reused for coke firing. Surplus gases are supplied to Nippon Steel Corporation (Yawata Works).
Tar, diesel oil, and ammonia are extracted in the gas purification process, and are sold as byproducts. Generated heat is also collected as electric power. And, both resource recycling and CO2 reduction are achieved simultaneously.
Our mission is to lead the industry by our high quality coke production, while protecting the global environment.
