In the Duplex steel making process, treatment is carried out in two vessels/furnaces one after the other without any major break. Originally steel was first
in metallurgy, a steel-making process that is carried out in two successive steel-melting units (the process is sometimes also used to smelt cast iron,
The Duplex refining process which is composed of electric arc furnace melting, followed by converter refining, can be extended to a Triplex refining route by
This is merely a combination of the Bessemer and open-hearth processes. Pig metal is blown in an acid Bessemer converter until silicon, manganese, and part or

The meaning of DUPLEX PROCESS is a process for making steel in which the material is partially treated in a furnace of one type, originally a Bessemer,
A two-step procedure in which steel is refined by one process (usually the Bessemer process) and finished by another process (usually open-hearth or electric-
