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.

Abstract: Method and apparatus for casting a metal article in a mold at least as long as the article, utilizing a cooled mold of elongated form having top and bottom portions. The method includes the steps of introducing molten metal from a source through the bottom portion of the mold, flowing molten metal into the mold so as to form a solidifying casting shell which during casting occupies at least 40% of the cross-sectional mold area and has a molten core, and flowing molten metal from the source through the core towards the mold top. The rate of solidification is effectively governed, thereby avoiding the undesirable growth of columnar dendrites which result in localized solute concentrations, segregated inclusions and centerline porosity, all undesirable in a casting micro-structure.

Abstract: A metal article is cast in an elongated mould of high thermal conductivity by introducing molten metal through the bottom portion of the mould. Molten metal is flowed into the mould so as to form a solidifying casting shell which during casting occupies >=40% of the cross-sectional mould area and has a molten core. The metal is flowed until the shell extends to the mould top and the core is subsequently solidified. Used for casting billets. The molten core sweeps the solid-liquid interface formed by the shell and inhibits columnar dendritic growth during filling of the mould. Several moulds may be filled simultaneously from a single molten metal source. The inclusions and impurities tend to be carried to the top of the mould. Centre line porosity is minimised.

Abstract: Continuous casting of metal in which molten metal contacts a cooled axial mold wall surface to form a skin increasing in thickness in a direction toward a discharge opening of the mold. At least a portion of the last-mentioned mold surface increases in cross-sectional size over its length in the direction of the discharge opening. The casting is relatively withdrawn from the mold at an average casting rate during the casting operation and also the casting and the mold are oscillated relatively to one another in a particular manner. The maximum velocity capability of oscillation is greater than the casting rate. During oscillation and relative movement of the mold in the casting direction, a substantially constant, compressive loading of the last-mentioned mold surface portion on the skin of the casting is maintained throughout a portion of the last-mentioned movement. Concurrently with the relative movement of the mold in the casting direction, the resistance of the casting to mold movement is allowed to slow the mold velocity to approximately that of the casting, so as to minimize hot tearing of the skin of the casting.

Abstract: Strain reduction or reversal technique for continuous casting of a metal billet element wherein there is provided an axial mold wall which is oscillatable, a plug element in the axial wall which may be solid in the sense that it closes one end of the mold or which may be of a type in which molten metal may flow therethrough into the mold, one of said elements being oscillatable with respect to the axial wall in a manner to relieve strain on metal newly freezing to the axial wall during oscillation of the axial wall.

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.
