METHOD AND APPARATUS FOR COMBINATION PROCESS OF CONTINUOUS CASTING AND ROLLING OF COPPER ALLOYS Russian patent published in 2002 - IPC

FIELD: metallurgy, possibly processes for combination continuous casting and rolling of copper alloys. SUBSTANCE: method comprises steps of preparing melt, accumulating it in mixer, removing oxygen from melt copper, alloying it by alloying component in the form of rod, feeding melt to receiving bath of casting machine in which heel of melt is covered with baked petroleum coke and(or) graphite lumps; forming continuously cast billet in mold; discharging hot cast billet and feeding it to continuous rolling mill. Before starting casting process at heating bath, pouring pipe is covered with lid of graphite at side of stop device. Graphite plug is inserted to lower portion of pouring pipe. After heating bath directly before casting process lid and plug are removed. At inlet of stream into receiving bath of casting machine stream is directed to opening of graphite plate arranged on surface of melt and simultaneously inert gas is supplied through opening of graphite plate to zone of introducing alloying component. Then stream of melt is directed to mold through pouring pipe of receiving bath. EFFECT: enhanced efficiency of continuous casting and rolling processes of copper alloys, improved quality of rolled rods. 5 cl, 2 dwg, 1 ex
