Abstract
A continuous casting apparatus comprises a mold and a tundish connected to each other by means of a refractory conduit capable of withstanding several cycles of casting operations. Used on the continuous-casting apparatus is a dummy bar assembly whose head is bevelled on both sides thereof adjoining the mold wall. The bevelled portions of the dummy-bar head and the mold wall define a gap expanding in the direction of the withdrawal of the ingot. A sealing material, such as asbestos string, is placed in the gap and tamped therein by a special means.
Claims3
A continuous casting apparatus comprising a tundish;
- a mold connected to said tundish by a refractory conduit capable of withstanding a plurality of casting cycles;
- a dummy-bar fed into said mold and equipped with a head section packed with a heat-resistant material on its surface adjacent the mold walls, sides of said dummy-bar head adjoining the mold wall being formed with bevelled portions decreasingly tapering in the direction of withdrawal of the cast ingot from the mold, said bevelled portions together with the mold wall forming a gap expanding in the direction of withdrawal of the cast ingot;
- and a sealing material placed in said gap and means for tamping the seal into position, said means for tamping being disconnectable relative to the dummy-bar head and located behind the dummy-bar head.
