Steel - Casting of steel | Britannica
Steel - Steel - Casting of steel: The simplest way to solidify liquid steel is to pour it into heavy, thick-walled iron ingot molds, which stand on stout iron plates called stools. During and after pouring, the walls and bottom of the mold extract heat from the melt, and a solid shell forms, growing approximately with the square root of time multiplied by a constant.
