FIELD: metallurgy.
SUBSTANCE: invention can be used in iron-foundry production during melting of iron melt. Method comprises cleaning of main lining of electric arc furnace from false acid lining from silicon dioxide by introducing on bottom of electric arc furnace, heated not lower than 700 °C, barium-strontium carbonate, which forms free-running slag phase between bottom and charge, preventing sticking of charge components to main lining, neutralizing silicon dioxide and increasing basicity of slag in unreacted state on surface of molten iron bath, improving desulphurisation and graphite assimilation.
EFFECT: invention makes it possible to separate already stuck slag from the furnace main lining walls and prevents its growth during melting process.
