iron slag management process

  • What is an Iron Slag Abrasive Definition from

    May 10 2017 · Calcium silicate another name for iron slag abrasive is formed from the smelting of iron ore. During the smelting process the iron is placed into a blast furnace that is also loaded with limestone. The heated limestone forms calcium oxide which then attaches to the silicon present in the iron

  • Slag Atomising Technology (SAT) Strategic management of

    Slag Atomising Technology (SAT) Slag Atomising Technology is a process that converts molten slag (ºC) into small spherical balls with a diameter range of 0.1 to 4.5mm. The process consists of a high speed air blowing system with catalyst and water exposed to the stream of falling molten slag out of a tundish into the yard.
