Abstract

1. Method of casting steels with more than 0.02 weight percent metallic aluminium by continuous billet casting plants with freewheeling, calibrated tundish jets, characterized in that from 0.8 to 0.1 weight percent aluminium is added to the ladle, dependent on the C-content, in an amount from 0.04 to 2.0 of the aluminium content, and that thereafter calcium alloys in an amount of 0.05 to 1.2 times the amount in the ladle, based on pure calcium, is added to the ladle.
