METHOD OF PRODUCING VERMICULAR GRAPHITE CAST IRON BY THERMAL DROSS FORMATION ELECTRIC ARC PROCESSING Russian patent published in 1994 - IPC

Abstract RU 2016074 C1

FIELD: producing vermicular graphite cast iron at iron foundries of mechanical engineering plants. SUBSTANCE: charge is smelted in a electric arc basic furnace, the smelt is overheated to 1560-1580 C with basicity of slag ranging from 1,5 to 1,8 and the smelt modifying in the furnace through reducing magnesium and calcium from slag and lining. EFFECT: enhanced efficiency of process. 1 tbl
