HOW A BLAST FURNACE WORKS

2018-7-10 · The CaS becomes part of the slag. The slag is also formed from any remaining Silica (SiO 2), Alumina (Al 2O 3), Magnesia (MgO) or Calcia (CaO) that entered with the iron ore, pellets, sinter or coke. The liquid slag then trickles through the coke bed to the bottom of the furnace where it floats on top of the liquid iron since it is less dense.

Slag aggregates | Tarmac

Unbound steel slag in contact with groundwater initially increases the pH-value of groundwater to about 11–12 but this ''first flush finite'' effect diminishes once lime and magnesia have been washed from the surface. Similarly, blast furnace slag increases the pH-value and may also de-oxygenate stagnant groundwater.
