Manufacturing And Processing Of Iron And Steel Slags

  • IRON SOURCE – SCB International

    Steel Slag is a non-metallic byproduct of the steel making industry and consists of calcium, magnesium, aluminum and iron silicates. This slag Is formed when molten Iron, scrap metals and various fluxes, are oxidized by injecting large amounts of pure oxygen into the molten iron mix to create molten steel and molten slag.
