ABSTRACT:
A process for controlling the molten metal level in continuous thin slab casting in which molten metal poured from a large-sized tundish into a small-sized tundish through a sliding nozzle is caused to overflow from the small-sized tundish for casting through a tiltable casting spout into a twin-belt-type continuous casting machine is disclosed. The process comprises measuring the level of molten metal on the casting machine to provide a deviation signal representative of a deviation of the level of the molten metal from a target value; and adjusting a directly influencing factor on the molten metal level, such as a pouring rate of the molten metal into the mold and a pulling speed of the molten metal according to the deviation signal. Preferably, the process further comprises measuring the directly influencing factor to provide a deviation signal representative of the directly influencing factor relative to the normal value, and adjusting the degree of opening of the sliding nozzle of the large-sized tundish according to the deviation signal to regulate the pouring rate into the small-sized tundish.
