Liquid steel flows out of the ladle into the tundish, and then into a water-cooled copper mold. Solidification begins in the mold and continues through the caster and the strand, as it is now called, is straightened, torch-cut, and then discharged for intermediate storage or hot charged for finished rolling.

What is a Steel Mill? (with pictures)

A steel mill is a location where steel and iron are created from heating raw iron ore and other materials in a massive cauldron. Using large electric cauldrons to heat the iron ore, coke, calcium and a myriad of other materials into a red hot liquid, a steel mill pours the molten metal into molds where it cools.
