摘要： A continuous casting furnace for manufacturing an elongated cast product, for example, of copper or its alloy includes a housing defining a chamber. A crucible is accommodated within the chamber for holding a casting material. A heater is mounted on the crucible for melting the casting material. A generally vertically-disposed elongated casting nozzle hermetically extends into the chamber. One of the casting nozzle and the crucible is movable toward the other for immersing a lower end of the casting nozzle in the molten casting material in the crucible. The housing is connected to an inert gas source for introducing inert gas into the chamber when the casting material in the crucible is melted. When the lower end of the casting nozzle is immersed in the molten casting material, the molten casting material is moved along the casting nozzle by the pressure of the inert gas in the chamber. A cooling device is associated with the casting nozzle for solidifying the molten casting material when it is passed through the casting nozzle, thereby forming the elongated cast product.
