Raw material of electric steel making sponge iron

Product: Sponge iron

Color: Black/ blue

Usage: Steel making

Packing: 25 kg/bag or ton bag


Sponge iron, iron content less than 90% is used for blast furnace or electric furnace iron making. It can remove sulfur, phosphorus and other harmful impurities and non-ferrous metal content is conducive to the electric furnace smelting high-quality steel. More than 97% iron content also belongs to sponge iron.

Advantage of Sponge Iron

  • Low backwash frequency
  • High compressive strength
  • Large surface area
  • High activity
  • Good regeneration effect

Application of Sponge Iron

  • Steel making
  • Counter weight
  • Hot boiler
