slab casting

Slab casting is a metallurgical process used in continuous casting to solidify liquid steel into large, flat sections called slabs. This method involves feeding molten steel into a water-cooled copper mold, where it begins to freeze. As the solid shell forms, it is continuously withdrawn, along with the remaining liquid steel inside, and further cooled.123

Slab casters can produce sections up to 250 millimeters thick and 2,600 millimeters wide, with high production rates. This process is more efficient than traditional ingot casting, as it minimizes the need for reheating and rolling, leading to less raw material, energy consumption, and a higher yield of usable product. Advanced techniques like electromagnetic stirring and in-line rolling further enhance the metallurgical quality of the cast slabs.13
