Effect of MgO content in refining slag on the non-metallic inclusions in tire cord steel
Journal of Materials Research and TechnologyIn order to weaken the corrosion of refractory during the refining process of tire cord steel, the MgO content in the low basicity (w(CaO)/w(SiO2)≈1.0) slags was increased from 7.9% to 12.6% in industrial experiments.

Slag Refining of Iron with Respect to Phosphorus [PDF]
, 2014 TiZir Titanium and Iron produces high purity pig iron and titania slag from ilmenite. However, new ilmenite ores from Grande Côte Mineral Sands Project mine contain high level of phosphorus, which will contaminate the final iron product produced at the smelter in the future. As a result, a solution to remove the phosphorus from iron was needed.
