For iron and steel plants, Yaskawa offers optical control systems for various kinds of equipment, such as blast furnace facilities, continuous casting facilities, rolling equipment, and processing lines both inside and outside Japan. These systems contribute to stable continuous operation by virtue of their high reliability.
Yaskawa is using its drive technology to actively address the challenges of energy savings and reducing CO2 emissions at iron and steel
Unloads the iron ore or coal that was delivered by a raw material ship.
The unloaded raw materials are transported by conveyor and piled into separate hills.
The fine iron ore cannot be introduced directly into the blast furnace. Sintering converts and compacts the iron ore into large particles.
Heats coal to produce coke.
Cokes Dry Quenching
Coke is steamed and then cooled with nitrogen. The heat withdrawn is then
vaporized and sent to the furnace.
The iron ore and coke are charged into the furnace in layers and the iron ore is
melted by a hot blast of about 1,600°C to produce pig iron.
Pig iron is refined to produce steel (molten steel).
Molten steel is cast in molds to produce steel ingots, such as slabs or blooms.
Hot Rolling Mill
The slab is heated about 1000°C and rolled to produce a thin strip. The strip is
rolled into a coil.
Similarly, products such as H-beams or steel sheet piles can be produced from blooms and products such as wire rods can be produced from billets.
Cold Rolling Mill
The coiled strip can be cold-rolled to produce a strip.
The coil is automatically transported by a wide range of equipment.
Metal Processing Line
Processing, such as plating, annealing, or coating, is performed on the steel sheet.
