Copper moulds are critical components in the continuous casting of steel and the surface condition of the mould directly affects the product quality and premature failure/low wear life produce a detrimental effect on the output productivity of the continuous casting machine. This paper presents the failure analysis of a copper-based mould whose sides are coated with chromium. The performed analysis points out that the extended damage is due to two main causes: the failure origin is attributed to thermal stresses caused by working conditions and the copper wear is associated with the high zinc content of the liquid steel.

Abstract

Copper moulds are critical components in the continuous casting of steel and the surface condition of the mould directly affects the product quality and premature failure/low wear life produce a detrimental effect on the output productivity of the continuous casting machine. This paper presents the failure analysis of a copper-based mould whose sides are coated with chromium. The performed analysis points out that the extended damage is due to two main causes: the failure origin is attributed to thermal stresses caused by working conditions and the copper wear is associated with the high zinc content of the liquid steel.
