    • A molding device for vacuum casting a metal ingot is provided. The mold includes a mold cavity defined by an ingot mold, a core and a bottom. The mold is arranged inside a vacuum-cast enclosure and includes a source of introducing molten metal at the upper portion thereof. A distribution device for receiving and distributing molten metal, which is suitable for receiving the molten steel introduced into the vacuum-cast enclosure and for redistributing the molten metal in the mold cavity, is arranged at the upper portion of the mold cavity. The molten metal is introduced into the enclosure so as to form a first jet of molten steel under a vacuum, in order to pour the molten metal over the distribution device and to form at least one second jet of molten steel under a vacuum, which originates with the distribution device and terminates in the mold cavity so as to fill the mold cavity with molten metal.
    • 提供一种用于真空铸造金属锭的成型装置。 模具包括由铸模,芯和底部限定的模腔。 模具设置在真空铸造外壳内,并且包括在其上部引入熔融金属的源。 用于接收和分配熔融金属的分配装置设置在模具腔的上部,熔融金属适于接收引入真空铸造外壳中的钢水并将熔融金属重新分配在模腔中。 将熔融金属引入外壳中,以便在真空下形成第一钢液流,以便将熔融金属倾倒在分配装置上,并在真空下形成至少一个第二射流的钢水 与分配装置一起终止在模腔中,以便用熔融金属填充模腔。
