Abstract
A method for smelting cast iron, including loading charge materials, melting and introduction into the melt of vanadium, titanium and magnesium oxides and high-polymer waste compounds, characterized in that, simultaneously with the introduction of oxides and waste, the exhibit cathodic polarization of the cast iron melt at a constant current load, component 0.1-10 A/dm2 calculated on the surface of the melt mirror, while As a counter electrode, a graphite electrode with an end area of up to 0.8 is used area of the melt mirror, which is under mechanical load and under electrical under tension, immerse in slag at a distance of 30-70 mm from the surface of the melt, with In this case, the ratio of cathode and anode current densities is 0.9-1.2.
