    Encyclopædia Britannica Inc. In general the more reactive a metal is the more likely it is to undergo a chemical reaction and form a compound. A comparison of the reactions of metals with water oxygen and acid can be used to rank the metals in the order of their reactivity—from most to least reactive. This list is called a reactivity

  • Chapter 9 Oxygen Steelmaking Processes Semantic

    The oxygen steelmaking process rapidly refines a charge of molten pig iron and ambient scrap into steel of a desired carbon and temperature using high purity oxygen. Steel is made in discrete batches called heats. The furnace or converter is a barrel shaped open topped refractory lined vessel that can rotate on a horizontal trunnion axis. The basic operational steps of the process (BOF) are
