A PROCESS OF WIRE INJECTION IN STEEL MELTS FOR ALUMINIUM WITH STEEL CLADDING

摘要

An improved wire injection process for introducing aluminium in liquid steel bath in which the bath temperature and the chemistry of the liquid steel being adjusted in a secondary treatment unit according to the desired quality, characterized in that a prefabricated aluminium wire is caused to move at a predetermined speed for injection in the steel bath such that the aluminium melts close to the bottom of the ladle, and in that the dimension of the aluminium wire including the moving speed of the wire being designed in corresponding with the superheat of the steel bath and the liquid column height.
