Density: Deoxidation iron from the roof into the furnace, must be able to pass through the slag layer, to stay in the slag / steel liquid interface, so you can ensure efficient heat transfer and chemical reactions. If Deoxidation iron density is too low, it will float on the surface of the slag; and high density of the liquid steel will wear to go.

To produce cast iron, the iron must be extracted from iron ore. The ore is smelted in a blast furnace where it separates into pig iron and slag. The furnace is heated to around 1800 degrees Celsius in an oxygen atmosphere and the slag formed rises to the top and can be removed. The molten pig iron below contains around 3 wt.% – 5 wt.% carbon.
For instance, ash from coal combustion contains considerable amounts of the oxides of silicon, iron, aluminium and other metallic oxides. Iron oxides can be separated magnetically, the ash can be melted to produce ferro silicon and the aluminium rich slag. The secondary sources containing metals also include slags, dross and flue dust.
