Реферат: 1521194 Tundishes VEREINIGTE ÍSTERREICHISCHE EISENUND STAHLWERKEALPINE MONTAN AG 23 Feb 1976 [25 Feb 1975] 7053/76 Heading F4B [Also in Division B3] Steel being poured into a mould 2 from a tundish 1 is flushed with gas such as N 2 or Ar from a lance 10 urged, as by a spring 15 or hydraulically, into a lateral bore 9 (of 2-10 mm) in a casting tube 3 so that the lance end seals against the bore wall or tube wall adjacent the tube. Inclusions 13 are entrained by bubbles 12 and carried to a slag layer 8. The outlet end of the lance, possibly with a refractory cap, may be rounded to make a circular line contact in a conical lateral bore, or it may have a straight cut end, possible with a reduced portion as in Fig. 6, for seating in a counterbore, or it may abut against the outer casing of the casting tube 3 around the inlet end of the bore 9. In any case, sealing material 21 is used.
