Abstract: Apparatus for continuous casting of metals including a cooled axial mold wall defining at least part of a mold cavity and a wall structure extending transversely of the axial wall and located therein, provided with a solid cooled sealing element of resilient graphitic material extending therearound and internally abutting the axial wall which is moved on its axis relatively to the transverse wall. On the face thereof which contacts molten metal and covering a portion of the sealing element in overlapping relation, such transverse wall has a refractory element having an outer surface portion thereof adjacent the axial mold wall disposed at an angle to the last-mentioned wall. There is also provided a nozzle structure having improved thermal characteristics for delivering molten metal to a mold cavity for continuous casting.

Abstract: A tundish receiving a first molten metal and a closed-end mold are moved apart relative to each other so that the mold forms a solidified shell of a billet, molten metal flowing through the solidified shell to the mold. During the casting, a second or altered molten metal is introduced into the tundish to flow through the elongating billet so that a continuously cast billet is produced with a core of one metal, a layer of alloyed metals, and a shell of another metal. Billets may be produced with steel cores and stainless steel shells, ''''killed'''' steel cores and ''''rimmed'''' steel shells, and other combinations. Tubing may also be formed by the continued relative separation of the tundish and the mold after the source of molten metal is exhausted.
