Abstract
An electromagnetic conduction pump for liquid metal, including a part of refractory material; two magnetic circuits each including a horizontal arm embedded in the refractory material, the first having a gap and the other being closed; a rising channel arranged in the refractory material for pumping of the liquid metal passing through the gap in the first magnetic circuit and a closed turn of liquid metal communicating with the rising pumping channel at the place where it passes through the gap. The turn consists of a channel of inverted-U shape the legs of which dip into the bath of metal, one of the legs consisting of a section of the rising channel and the other leg partially interlacing the horizontal arm of the second magnetic circuit.
Claims3
An electromagnetic conduction pump for liquid metal, comprising
- (a) a part of refractory material which can be submerged in a bath of liquid metal;
- (b) a first magnetic circuit including a horizontal arm embedded in said refractory material and having a gap;
- (c) a second closed magnetic circuit having a feed coil and including a horizontal arm embedded in said refractory material;
- (d) a rising channel in said refractory material for pumping of said liquid metal passing through said gap in said first magnetic circuit and a closed turn of liquid metal communicating with said rising pumping channel at the location where it passes through said gap;
- (e) said turn comprising a channel of inverted-U shape the median plane of which is a vertical plane passing through said gap in said first magnetic circuit, the legs of said U dipping into said bath of metal in order to close said turn, one of said legs consisting of a section of said rising channel and the other leg partially interlacing said horizontal arm of said second magnetic circuit.
