  • Process for producing pipe blooms
    Patent number: 4091524
    Abstract: A process is provided for producing long tubular blooms, generally having a length to diameter ratio in excess of 20:1 in which molten material is rapidly poured into a chill mould whose axis is transverse to the horizontal, sealing the mould and immediately tilting the mould to a generally horizontal axial position while rotating about its axis, inserting a mandrel axially of the viscous center axis of the material and processing the material around the mandrel to form a tube after which the mandrel is removed.

  • Thin-wall molds for casting elongate ingots
    Patent number: 4078762
    Abstract: A casting chill mold is provided for producing elongate metal ingots having a length to diameter ratio in excess of 10:1 in which the wall thickness of the mold is substantially no greater than that required to enable the walls to withstand the hydrostatic pressure of the melt upon the occurrence of thermal stress. Preferably the mold is surrounded by a spaced supporting framework contacting the outer surface of the mold at spaced discrete small area points of contact.
