Main Equipment and Production Processes
Raw Materials and the Manufacture of Steel
The blast furnace turns the iron ore into pig iron, the chief ingredient used to make the steel. Inside the blast furnace, coke and iron ore are alternately poured in from above, while air heated to 1,000-1,200 degrees Celsius is blown in from below. The iron ore melts and reduces to give pig iron, which is then conveyed to the next process by a torpedo car or molten iron ladle.

The Steelmaking Process
The molten pig iron is treated by preparative equipment to separate impurities such as sulfur and phosphorous, then further refined by removing carbon with the use of a steel converter. Once the impurities are removed by these methods, the viscose substance remaining is known as "steel." Next, the molten steel is transported to the continuous caster and cast into billets (slabs, beam blanks, and blooms) that can be easily rolled.

Rolling
Rolling is the process by which billets are converted into sheets with thicknesses ranging from less than 1 mm to 400 mm. JFE's rolling technology is a product of long-running research and development. Rather than simply "rolling" the steel, the process actually changes the crystal structure of the metal, allowing JFE to determine the strength, flexibility, and other properties of the final product.

Coating and Plating
  Steel sheets with a beautiful sheen and high rust resistance can be manufactured by applying different platings to the surfaces of cold rolled sheets.
The production line at the West Japan Works is equipped with facilities for all kinds of plating, including continuous galvanizing electrolytic galvanizing, lacquering, paint plating for a variety of purposes, and tin plating (as well as a tin-free steel line).
