CASTING THIN STRIP AND DELIVERY NOZZLE THEREFOR

摘要

A method of casting metal strip and equipment therefor where an elongated metal delivery nozzle extending along in a continuous caster with at least one segment having a main portion adapted to deliver molten metal in the casting pool above the nip along the metal delivery nozzle and an end portion adjacent side dams having a reservoir portion with first and second pairs of passages adapted to deliver molten metal into a molten metal pool adjacent the side dams while shells are forming on the casting rolls. The first pair of passages adapted to deliver molten metal into the casting pool adjacent the side dams, and the second pair of passages adapted to deliver molten metal into the casting pool adjacent the molten metal from the first pair of passages adjacent the side dams to inhibit formation of skulls during the formation of the cast strip during a casting campaign.
