A process for continuously casting thin slabs, which comprises the steps of pouring a molten metal from a large-sized tundish through a sliding nozzle into a small-sized tundish, over-flowing the molten metal from the small-sized tundish to pour the molten metal into a continuous casting machine of the twin-belt type is disclosed. According to the process, a pouring rate into the small-sized tundish is calculated prior to overflow on the basis of a change in weight of the small-sized tundish and the degree of opening of the sliding nozzle is adjusted so as to make the calculated pouring rate come close to the target pouring rate into the small-sized tundish or into the casting machine.
