Overview of Injection Technology, desulphurization, deoxidation, alloying, and inclusion shape control. One of the first ordinary ladle metallurgical processes was the Perrin process , in which steel was tapped into a ladle containing premelted slag. The kinetic energy of the steel was used to produce a large reaction surface and intensive stirring in the ladle.

The Fundamental Aspects of Injection Metallurgy,e practical and economic aspects of injection processes, with emphasis on “What can be accomplished?” and “At what cost?”, there are sound reasons for examining the theoretical basis of these operations.

Injection Practice in the Secondary Metallurgy of Steel,ical operating guidelines. In an ideal world, practice would be fully based on theory, and all the practices would have a complete fundamental explanation and justification. This would then represent a complete harmony between the material in this chapter and that given in Chapter 2.
