METHOD FOR MAKING THIN METALLIC SHEET OF THIN CAST STRIP AND AUTOMATIC MANUFACTURING LINE FOR PERFORMING THE METHOD Russian patent published in 2005 - IPC

FIELD: metallurgy, namely production of thin steel sheet from thin cast strip.

SUBSTANCE: method is realized due to matched operation of melting and single-roll aggregates in condition of automatic control of processes of melting, feeding melt metal for casting, casting thin strip, rolling strip to thin sheet and discharging commercial product. Method comprises steps of supplying metal to cooled roll from lower side; providing necessary area of its contact with roll due to raising metal meniscus in casting chamber of single-roll aggregate; raising metal meniscus by rotating melt metal in melting chamber due to action of electromagnetic field and lifting metal relative to walls of melting chamber and in vertical duct of additional vessel. Melt metal is fed into vertical duct of additional vessel from melting chamber through lower horizontal metal conduit. Melt metal is fed from vertical duct of additional vessel to casting chamber of single-roll aggregate through upper horizontal metal conduit in which metal is supplied at controlling its level over metal conduit. Remaining melt metal is removed out of casting chamber after termination of casting due to interrupting metal rotation in melting chamber and it is poured to melting chamber of melting aggregate.

EFFECT: lowered investment expense, reduced maintenance cost, enhanced efficiency of line.
