  • Patent number: 4615660
    Abstract: An electromagnetic metal melt pump for pumping and delivery molten metal from a furnace, having a ground plate, an inductor attached to the ground plate, an inductor attached to the ground plate and including a laminated iron body having slots in which a multiphase winding is placed. A metal melt tank made of magnetizable material is provided with heat insulation and is attached to the laminated iron body. A suction tube (7) is coaxially placed in the metal melt tank (3), the suction tube (7) comprises three main parts: the first part is a suction tube (7c) having a volume (V.sub.4) for closing the magnetic circuit of the inductor between points A and B which determine the immersing depth; the second part is a buffer tank (7b) having a volume (V.sub.1) to produce a reduced pressure space between points B and C; the third part is a suction tube (7a) having a volume (V.sub.2) for creating a reduced pressure in the suction tube (7) immersed into the metal melt of the furnace.

  • Patent number: 3941088
    Abstract: Standing-wave metallizing apparatus for coating a substrate with a molten metal of a melting point lower than that of the material of the substrate, comprising a tank with a bath therein for the molten metal, a pump outside the tank for heating the metal and for circulating the same to and from the bath, the pump having a magnetic circuit with an air gap therein, thereby to produce laminar flow of the molten metal in the pump, which results in a standing-wave pattern, by the aid of which the substrate is coated with the molten metal.
