Japanese Patent JPH0222621

B2

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 (V4) 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 (V1) to produce a reduced pressure space between points B and C; the third part is a suction tube (7a) having a volume (V2) for creating a reduced pressure in the suction tube (7) immersed into the metal melt of the furnace. The suction tube ( 7) is provided with controllable heaters (7d) and with heat insulation (7e). The ground plate (1) is fixed on a lever and tilting plate of a lever equipment (8a). The suction tube (7) is attached to a lever rod (8b) of the lever equipment (8), the lever rod (8b) can be rotated around its axis (FIG. 1).
