Magnesia-Carbon Refractories There is some confusion which can arise from the term magnesia (MgO) refractory. The American Society for Testing and Materials (ASTM) defines magnesia as ‘a dead-burned refractory material consisting predominantly of crystalline magnesium oxide’, but that is not the terminology used at every place. The terms magnesite, magnesia and MgO are sometimes used inter-changeably …
Read MoreFoaming of Slag in Basic Oxygen Furnace In basic oxygen furnace (BOF) steelmaking, a supersonic oxygen (O2) stream is injected onto the surface of the hot metal bath. The impurity elements in the bath such as carbon (C), silicon (Si), manganese (Mn), and phosphorus (P) are oxidized and removed from the bath in the form …
Read MoreSlopping of Slag in Basic Oxygen Furnace Steelmaking in basic oxygen furnace (BOF) is a batch process in which steel is made from liquid iron. The concentration of elements such as carbon (C), manganese (Mn), and phosphorous (P) have an impact on the steel quality. For the steel to be cast, it needs to be …
