1.1 Location in the steel industry
Steelmaking, from the iron-bearing raw material to the casting of the liquid metal in ingot moulds (now mainly in continuous casting ingot moulds (over 95% in France), can be represented by a graph (figure ), which attempts to describe the entire process, by following the evolution of the oxygen potential of the iron-bearing material.

Statistical and economic data
Since the early 1960s, the development of a large number of increasingly complex metallurgical processes that could not be carried out in the traditional steelworks reactor (oxygen converter or electric furnace, figure ) has given rise to a new type of metallurgy, known as "secondary" metallurgy, carried out in a steelworks ladle fitted with a range of equipment, including drawer nozzles...
