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

Basic oxygen process Article about basic oxygen process
Basic Oxygen Process. a type of conversion of pig iron into steel without the consumption of fuel by blowing the pig iron in the converter from above with industrial-grade oxygen. The expediency of using oxygen in the production of steel by the converter method was pointed out as early as 1876 by the Russian metallurgist D. K. Chernov.

Other options are the Q-BOP process relying on bottom-blown oxygen steelmaking or a combination of top and bottom blowing. In all cases the refractories that line the vessel holding the molten steel are basic rather than acidic—hence the name.
