The pump is contained in a refractory block which is plunged into a melt of molten metal to be pumped. An electric current is induced to flow in the molten metal along a straight horizontal conduit in the block and the circuit is closed by the current flowing around the refractory block, within the melt. A magnetic field is induced horizontally at right angles to the current and a net upward pumping force is generated. By having only a part of the electric current circuit inside the refractory block it is relatively easy to clean out slag deposits after prolonged use. |
