ABSTRACT:
The invention relates to a lateral basin for electromagnetic pumping in a foundry and in particular in a light metal foundry. The pump comprises a magnetic circuit (207) which is locally saturated and which is embedded in the ceramic of the said basin. The electrical excitation winding of the magnetic circuit (208) is located outside the basin, and the circuit is disposed to create a horizontal leakage field through an active portion (204) of a liquid metal turn which, together with electrical current induced in said active portion (204), sets up a magnetic pumping force which is upwardly directed and which urges liquid metal into a duct (206) leading away from the furnace to liquid metal receiving means. The liquid from the furnace (202) supplies the active portion of the liquid metal turn (204) via a passage (205) of height limited by a partition (209). The electromagnetic pumping basin enables almost any casting requirements in a foundry to be supplied with liquid metal.
