ABSTRACT:
Installation comprising a reservoir crucible 11, 12 for molten cast-iron F with step-by-step extraction of a pipe T produced from the crucible comprising a cooled die. To obtain a cast-iron pipe of uniform thickness over its entire circular periphery, despite the absence of a core, the molten cast-iron F is set in slow rotation in the crucible by the tangential supply of molten cast-iron with a low rate of flow through a tangential orifice 18, by the rotation of a magnet 36 disposed in a hollow central relief 17 upstanding from the base of the crucible, by the rotation of paddle arms 44 disposed in the molten iron, or by the tangential injection of an inert gas.
