Industrial Machinery
Steel Manufacturing Furnaces, Rolling Mills
IHI has constructed large blast furnaces, the symbols of steel mills, which have the capacity over 5,000 m3, and has developed the latest system in electric arc furnaces. IHI has also successfully developed and provided the first commercialized strip caster in the world, which contributes in energy saving and low CO2 emission, as well as low cost and less space. IHI is also supplying rolling mills and control systems for steel and nonferrous materials such as aluminum and copper.
Blast furnace
Blast furnaces are the symbols of steel mills. The height of large blast furnace plants with daily output of 10,000 tons is over 100m. Since 1941, IHI has built and relined over 90 blast furnace plants, which are now playing important roles not only in Japan but also in various countries such as Australia, Korea, Brazil, and Taiwan. IHI has also supplied over 25 bell-less top charging systems for feeding raw materials into these blast furnaces.

DC electric arc furnace
Electric arc furnaces produce steel, using scrap as raw material and have been supplied worldwide. A new furnace which significantly increases productivity by simultaneous preheating and feeding of raw material has been developed and available.
Plate mill facility
Plate mills produce steel plates with high accuracy in width, thickness and shape, which support the infrastructure such as shipbuilding, bridges and industrial machinery. IHI supplies various types including wide plate lines and compact lines for electric arc furnaces, in accordance with the requirements of the customers.
Strip caster
The strip caster is a revolutionary facility which can directly produce thin carbon steel sheets thinner than 2 mm by running molten steel through twin cooling rolls. Compared to the conventional thin steel sheet mill, because the milling process is much more less, the CO2 emission is 1/5, and the energy consumption is 1/9, making it an environment friendly facility. It is able to use low-grade scrap molten steel, making it also a resource friendly facility.
Hot strip mill
Hot strip mills feature high-speed continuous production of hot rolled steel strips of 1.2-25.4 mm in thickness. The Compact hot strip mill is one-half the length of a conventional line and has been supplied worldwide as well.
Nonferrous rolling mill
The aluminum hot strip mill equipped with TP rolls makes it possible to achieve excellent crown control, which is benefit for high accuracy and quality rolling. As for the rolling of copper foil, the X-mill, which set rolls X-shape, can stably produce ultrathin products. Various types of mills for nonferrous materials such as hot rolling mills, cold rolling mills and foil rolling mills are available.
Stepping cylinder
The stepping cylinder is a positioning cylinder with a built-in mechanical feedback function, and it controls precisely the speed and the position by electrical pulse signals.
