Abstract
A tubular refractory channel (2) that can be inserted as a flowthrough for liquid metal into a thermally insulating outer lining (10) and can be connected with the outer lining (10) by a refractory mortar layer (9). In order to prevent liquid metal from penetrating into the mortar layer (9), even if the mortar layer contracts, the outer lining (10) overlaps the metal inflow-side of a front face (4) of the channel (2).
Claims19
An outlet structure for liquid metals, said outlet structure comprising:
- a tubular refractory channel having a front face at an inflow-side of said tubular refractory channel;
- an inductor disposed outwardly of said tubular refractory channel;
- and
- a thermally insulating outer lining positioned along an outer wall of said tubular refractory channel and overlapping the front face of said tubular channel, said outer lining being disposed between said inductor and said tubular refractory channel, wherein said outer lining and said tubular refractory channel are connectable by a refractory mortar or a cement layer.
A method of packing joints between first and second refractory parts to inhibit penetration of liquid metal into the joints, the method comprising:
- applying a refractory tape or a refractory cord around the second refractory part;
- and
- inserting the second refractory part into the first refractory part such that a joint is formed therebetween and an inflow-side front face of said second refractory part is overlapped by said first refractory part, wherein the first refractory part forms a thermally insulating outer lining.
