Abstract
A high speed twin roll casting process is described in which molten metal is fed through a feeding nose into a convergent cavity formed between the walls of two rotating rolls with a meniscus of hot metal extending from the feeding nose tip in a casting zone and the metal strip formed in the casting zone is reduced in a rolling zone. According to the novel feature, the tendency of the metal strip to stick to the rolls is significantly inhibited by shrouding the hot metal meniscus with an oxygen enriched atmosphere. Also when the metal is an Al--Mg alloy, the sticking is greatly inhibited by adding to the alloy a small amount of at least one alloying element selected from nickel, lead, indium and bismuth.
