PCT No. PCT/EP94/02619 Sec. 371 Date Feb. 16, 1996 Sec. 102(e) Date Feb. 16, 1996 PCT Filed Aug. 6, 1994 PCT Pub. No. WO95/05487 PCT Pub. Date Feb. 23, 1995Fresh gas is blown into the ring-shaped space between the annealing charge and the hood as an upwardly directed high-speed jet (9) at a velocity of approximately 80 m/s. The gas mixture which forms is evacuated through a gas outlet (10) arranged in the pedestal and diametrically opposite to the gas inlet. At a volume flow rate of about 130 m3/s, rinsing takes about 6 minutes.
