  • Blast Furnace Slag Granulation / Ironmaking / Our

    Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.

  • Dry Granulation of Blast Furnace Slag Steel360 News

    Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used
