Bolotova Y. Development of rational conditions for melting of aluminium alloy ingot on iron base during deoxidation of steel in ladle

On the grounds of results of mathematical modelling are determined regulatories of progress heat and mass exchange processes during assimilation aluminium alloy ingot on iron base in steel teeming ladle in fusing period. The calculation method is designed bearing in mind of interaction processes of space moving of aluminium ingots under the influence of hydrodynamics melting and its melt with further ho-mogenizing of melted adding in ladle. Rational progresses of working out the metal bath of aluminium alloys on iron base were developed and confirmed; all that ensure reduction of aluminium applica-tion during deoxidation of steel, decrease of process duration of out-furnace deoxida-tion and rise of uniformity of devision of addition in ladle. The results of the work were accepted with Ukrainian metallurgical mills for improvement of out-furnace technology of metal finish with the purpose of safe for energy and resourses.
