Abstract
Since its beginnings in the second half of the 19th century ingot casting technology has undergone a dramatic evolution. After continuous casting was introduced in the 1960s, ingot casting production has concentrated increasingly on large-dimension and niche products, which either cannot be coped with by continuous casting or are needed only in very small quantities. Downhill casting was gradually replaced by uphill casting. Refractory materials and casting fluxes have been substantially sophisticated. The quality and cleanliness of ingots must keep pace with the constantly growing requirements. Here modern special remelting processes are of decisive importance, as they have the potential to further improve the cleanliness of cast ingots. The smart combination of the various processes enables steel grades to be produced which, also in the future, will make ingot casting the only choice in many applications.
keywords Ingot casting, remelting, continuous casting, downhill casting, steel, refractory materials.
