Molten steel refined in the converter is solidified in this process to produce billets of a given shape. The molten steel discharged from the converter is continuously poured with a ladle into a mold below for cooling. After the steel is cooled and solidified, it is cut to a given length before it is conveyed to the rolling process for shaping.
