FIELD: processing of metal during continuous casting. SUBSTANCE: method involves supplying molten metal from pouring ladle to evacuator; creating residual pressure in evacuator; processing metal in evacuator; supplying metal intermediate ladle through branch pipe and further to crystallizers, with being supplied from evacuator to intermediate ladle through auxiliary branch pipe; providing circulatory vacuum processing of metal in intermediate ladle by supplying inert gas into one of branch pipes, when metal level in intermediate ladle is higher than lower ends of branch pipes and when evacuator is sealed by molten metal. When predetermined residual pressure is created in evacuator, vacuum processing of metal in evacuator is conducted simultaneously with circulatory vacuum processing of metal intermediate ladle, with metal mass in intermediate ladle being divided into three zones: middle zone and two end zones. Circulatory vacuum processing is effectuated in middle zone. Ratio of volumes of metal on evacuator bottom and in the middle zone of intermediate ladle is set to be within the range of 0.4-0.6. EFFECT: increased capacity and high quality of metal. 1 tbl, 1 dwg
