pitkittäisvalaukseen

Pitkittäisvalaus, often translated as continuous casting or strand casting, is a metallurgical process used for the high-volume production of semi-finished metal shapes. This method allows molten metal to be solidified into a continuous strand of a specific cross-section, which is then cut into desired lengths. The process typically begins with molten metal being poured into a water-cooled copper mold. As the metal begins to solidify on the outer surface, it forms a shell. This partially solidified strand is then continuously withdrawn from the mold and further cooled by water sprays. As it moves through the secondary cooling zone, the core of the strand solidifies completely. Once the strand reaches a sufficient length and strength, it is cut into manageable pieces using an automated cutting torch or shear. The primary advantage of continuous casting is its efficiency and cost-effectiveness compared to traditional ingot casting. It eliminates the need for reheating and secondary forming operations like blooming or slabbing, leading to reduced energy consumption and higher yields. The process can produce various shapes, including slabs, blooms, and billets, which are then further processed into final products such as plates, structural shapes, and wire rods. Continuous casting is widely employed in the steel, aluminum, and copper industries.
