Abstract

The continuous casting process is used for most steel products. However, product sections of large size are still manufactured by the ingot casting process. A large semi-continuous casting process has been developed with a maximum mold size of 700×1400 mm to replace the large-sized ingot casting process. Extra low casting speed (0.05–0.10 m/min) and direct pouring from ladle to mold improves steel quality and simplifies the structure of the machine. With this caster, high quality steel has been obtained which has finer and more uniform internal quality than that of ingot casting.
