Have you ever wondered how molten steel becomes a neat billet? The answer lies in Continuous Casting. This is one of the most critical steps in modern steel production, completely replacing the labor-intensive and energy-heavy old ingot casting. The principle involves pouring refined molten steel from a ladle through a tundish into a water-cooled copper mold with an open bottom. The steel rapidly cools against the mold walls, forming a solid shell while the interior remains liquid. The machine then gradually withdraws the strand, and it is sprayed with water for secondary cooling until completely solidified. Finally, a torch cutter cuts it to specified lengths. This continuous process greatly improves metal yield and production efficiency, forming the basis for large-scale, low-cost steel manufacturing.
