Steel - Electric-arc steelmaking: About one-quarter of the world’s steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
In steelmaking, the formation of a lime-based desulphurising slag is promoted by adding, with the lime, an additive including at least 20% by weight Al.sub.2 O.sub.3 and including one or more of oxide of iron, magnesium, manganese and titanium, and melting below 1600.degree.C.
