Q-BOP

Several variations of the oxygen steelmaking process have been developed. They include bottom-blown converters (e.g., the OBM process, the Q-BOP process and the LSW process) and the top-blown converters (e.g., the LD process, its variant the LD-AC process, the Kaldo process and the Oberhausen process) [27.3,27.8]. 

The chemical requirements for the injection grade quicklime used in steelmaking processes such as the LD-AC and the Q-BOP, are similar to those in Table 27.3. The lime is groimd to suit the requirements of the injection system (e.g., Table 27.1). 

Energies are in a.u., charges q) and BOPs in electrons, distances in A and angles in degrees.
