Continuous casting is a highly efficient process used in the steel industry to produce high-quality metal products. It involves the continuous pouring of molten metal into a water-cooled mold, which results in the formation of a solidified product. Continuous casting machines play a crucial role in this process, as they ensure the smooth and continuous flow of molten metal while maintaining the desired temperature and shape of the product. The working principles of continuous casting machines are based on a few key elements. The first is the mold, which is usually made of copper or steel and is water-cooled to facilitate rapid solidification of the molten metal. The mold is designed to have a specific shape and size, which determines the final product's dimensions. The second element is the tundish, a reservoir located above the mold, which holds the molten metal before it is poured into the mold.
