Feeding molten metal, esp. steel, into continuous casting plant - part of metal in large ladle being fed into sec ladle for reheating and adjustment of its compsn.

摘要

A main ladle (I) is filled with molten metal, and the characteristics of the metal, e.g. its compsn and temp., are adjusted. Part of the metal in ladle (I) is then transferred to a smaller, sec ladle (II). The metal remaining in ladle (I) is then poured into a continuous casting plant, while the metal in ladle (II) is reheated and possibly subjected to a metallurgical treatment. After ladle (I) has been emptied, the metal in ladle (II) is poured into the continuous casting plant. Ladle(II) pref has a capacity of 1/3-2/3 of that of ladle(I); and more than one ladle (II) may be employed. Ladle (I) is pref provided with one or more bottom outlets. When using large main ladles (I), e.g. of 200-300 t capacity, a long time is needed to empty the ladle into the continuous casting moulds, so the metal in the ladle (I) cools and may alter in compsn. The invention eliminates these problems.
