Abstract
A method of preparing a mold surface for a continuous casting machine includes steps of machining the mold surface to a substantially smooth surface, and work hardening the machine surface substantially throughout to impart a compressive stress to the surface. In the preferred embodiment, this work hardening is performed by applying a controlled shot peening process to the mold surface. The surface may then be buffed to a smooth finish, or coated with a material such as nickel or chromium. The residual compressive stress that is created by the work hardening stops cracks from forming or spreading in the moldface wall. This increases the life of the moldface, and makes the casting machine safer and more efficient to operate.
