摘要:
An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.
摘要:
A method and device for the controlled tempering of a casting trough integrated between a supply vessel for a molten metal (e.g., copper or a copper alloy), and at least one continuous casting mold. The trough walls and the trough floor of the casting trough are at least partially provided with a lining layer having a specific electrical resistance between 10−1 &OHgr;·m to 10−6 &OHgr;·m and being resistant to the heat of the molten metal. The lining layer is inductively heated by an electrical heating device arranged around the lining layer.

Alloys are demonstrated based on copper, which have additions of manganese and sulfur and/or calcium as well as additional elements. The copper alloys are free from tellurium and lead, and are distinguished by high electrical conductivity and good machinability.
