ABSTRACT
A roller for continuous casting machines is of a basical-
ly drum-shaped configuration and has a cylindrical surface. The
roller has a ductile, corrosion-proof buffer layer on its surface,
of a thickness not exceeding about 0.1 mm, a melting point in
excess of 1000°C, and an elongation at fracture exceeding 10%. An
outer, corrosion- and abrasion-resistant layer covers the buffer
layer and has a greater thickness than the buffer layer. The
buffer layer is made of nickel or a nickel alloy, and is an
electrolytically deposited layer, the outer layer being of a
sintered configuration.
