Abstract

Process for the continuous casting of a molten steel to form high-quality billets or blooms, utilizing a device of the type comprising a buffer tank, an immersion pipe, a casting mould, and a line for feeding the molten metal to the buffer tank, the immersion pipe being connected to the bottom of the buffer tank and, during operation, extending as far as into the casting mould, the buffer tank being designed so that it can be closed off in a gastight manner and being provided in or in the vicinity of its top wall with a suction opening, and the feedline opening into the buffer tank in the vicinity of its bottom, while the other end of the feedline is connected to the bottom of a tundish, which bottom lies at a higher level than that of the buffer tank, and means being present for injecting a flush gas into the molten steel at the location of the feedline, in which method argon is injected as the flush gas, and gas is extracted from the buffer tank via the suction opening until an absolute gas pressure of < 15 mbar is established in the top of the said buffer tank, and argon is injected in a volume of > 25 l STP (volume at standard temperature of 0 DEG C and standard pressure of 1 atmosphere) per tonne of cast steel. <IMAGE>
