ABSTRACT:
Method and apparatus for continuously casting metal tubing, utilizing an oscillatable mold, which lends itself to the casting of tubing of relatively large internal diameter. Molten metal is poured directly into the mold having a chilled axial wall structure, and then a starting bar, having at least an annular end portion immersed in the molten metal in the mold, is moved relatively to the mold to withdraw the solidifying cast metal tubing adhering thereto, during oscillation of the mold, the molten metal for such tubing being supplied from the mold. The supply of molten metal in the mold may be replenished by pouring additional molten metal directly into the mold through the annular starting bar without contact of the molten metal with either the starting bar or the solidifying tubing prior to the entry of such molten metal into the mold.
