Abstract

The present invention relates to metallurgy and, in particular, the methods of the molten steel deoxidation and alloying with aluminium. According to the present invention there is provided a method of molten steel treating with Aluminium. Wherein the Aluminium is placed in the melt together with the Iron-based Alloy, and wherein the Aluminium and Iron-based Alloy are put into the Melt in the form of Composite with initial density which value is not less than 0.4, if compare to the molten steel's density, and which contain Al, C, Si, Mn and Fe, and wherein range of ingredients is as follows (% of mass): Al 25-50 C 0.05-0.90 Si 0.05-1.50 Mn 0.15-1.25 Fe the Rest, by the way, the composite contains Aluminium as the matrix component and other ingredients - in the form of Iron - based alloy and as the reinforced component by the way the Aluminium Dissolution in the molten steel is realized by the continuous increasing of the composite relative density to the value of 1.00-1.05. Application of the present invention ensures efficiency improvement of the molten steel treatment with Aluminium assimilation and aluminium losses decreasing.
