    • The invention relates to the field of monocrystalline casting and more specifically to a mould (1) for monocrystalline casting, and to the manufacture and use of this mould. In particular, this mould (1) has a moulding cavity (7) comprising a first volume (7a), a second volume (7b) and a grain duct (4). The second volume (7b) is situated on top of the first volume (7a), in communication therewith, and comprises at least one horizontal projection with respect to the first volume (7a). The grain duct (4) has a lower end (4a) connected to the first volume (7a) and a top end (7b) adjacent to said horizontal projection of the second volume (7b). The mould (1) also comprises a divider (11) interposed between said second volume (7b) of the moulding cavity (7) and the top end (4b) of the grain duct (4).
    • 本发明涉及单晶铸造领域,更具体地涉及用于单晶铸造的模具(1),以及制造和使用模具。 特别地,模具(1)具有包括第一容积(7a),第二容积(7b)和谷物管道(4)的模腔(7)。 第二容积(7b)位于与第一容积(7a)连通的第一容积(7a)上,并且包括相对于第一容积(7a)的至少一个水平突出部。 谷物管道(4)具有连接到第一容积(7a)的底端(4a)和与第二容积(7b)的所述水平突出部相邻的顶端(7b)。 模具(1)还具有插入在模腔(7)的第二体积(7b)和颗粒通道(4)的顶端(4b)之间的分隔件(11)。
