  • Basic oxygen furnace slag

    Basic oxygen furnace slag BOS (also called LDconverter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace. In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen. The slag is generated by the addition of fluxes, such as lime[stone] and/or dolomite that ...

  • Recycling of ladle furnace slags

    There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF). However, due to the fact that ladle furnaces(LF) have only been constructed in significant numbers since the 1980's, the relatively low slag volume in comparison to the other slags and also the high variability in slag chemistry, very few papers have ...

  • Blast Furnace

    The blast furnace process has been the primary method for producing iron for many decades. The blast furnace is a refractorylined circular shaft 100 to 200 feet high, with an internal diameter between 20 and 45 feet. The refractory wall lining typically measures two feet or more in thickness and contains more than 2,500 tons of refractories. Blast furnaces produce iron by exposing iron ore ...

  • Aircooled stainless steel slag

    The EAF slag has a lower density than steel and therefore floats on top of the molten steel. Once the steel has been tapped into a ladle, the slag is either poured from the furnace onto the floor where it is cooled and removed for further processing, or into slag pots where specially designed vehicles are used to transport the slag to purposebuilt lagoons, where it is tipped and cooled prior ...
