This document provides an overview of the history and processes of continuous casting of metals such as steel, aluminum, and other alloys. It discusses some of the earliest developments in continuous casting in the 1840s and the commercialization of casting processes in the 1930s. The key types of continuous casting processes described include direct-chill casting, twin-roll casting, and casting of steel. Factors that influence casting such as mold depth and speed of solidification are also summarized.
