jatkuvainkjettekniikkaa

Jatkuvainkjettekniikkaa, often translated as continuous casting or strand casting, is a process used in metallurgy to solidify molten metal into a semi-finished billet, bloom, or slab for subsequent rolling into products like rebar, structural steel, or sheet metal. This method offers significant advantages over traditional ingot casting, primarily in terms of efficiency and quality.

In continuous casting, molten metal is poured into a water-cooled mold. As the metal passes through the mold, its outer shell solidifies, forming a continuous strand. This strand is then supported and further cooled by a series of rollers and water sprays as it moves horizontally or at an angle. Once sufficiently solidified, the strand is cut into desired lengths.

The key benefit of continuous casting is its ability to produce a more uniform and defect-free product compared to ingot casting. The rapid and controlled cooling leads to finer grain structures and reduced segregation of impurities. Furthermore, it eliminates the need for reheating ingots before rolling, saving energy and reducing oxidation. This process is widely adopted in the steel industry and is also used for casting other metals like aluminum and copper.
