摘要： The invention concerns an ingot mould comprising in succession, in the direction for extracting the metallic product to be cast (7): a preheater (5) made of non-cooled refractory material acting as reservoir for the melting metal to be cast and a standard cooled tubular metal element (6) for solidifying the metal. A slot (18) for injecting the shearing gas (for example Ar) is arranged between the preheater (5) and the metal element (6) so as to emerge on the ingot mould internal periphery. The injection slot comprises means (17) for reducing the gas flow in each of the ingot mould angles, preferably formed by obstructing elements. The invention enables to reduce, even eliminate, defects encountered along the edges of the solidified cast products.

摘要： The invention relates to a continuous casting installation for metals, particularly steel, in which the submerged nozzle (8) is surrounded by an annular electromagnetic inductor (1) with a magnetic field that rotates around the casting axis, which is intended to drive the molten metal in axial rotation therewith. The invention is characterised in that the aforementioned inductor is of the polyphase type with a magnetic field passing therethrough and is equipped with a pair of projecting poles (3) per phase. Moreover, the end of each projecting pole opposite the nozzle is provided with a lateral narrowing (12) which increases the distance separating the polar ends (4). In this way, the inductor is extremely compact and very powerful and can deliver an intense traversing field into the central part of the nozzle, using a high-frequency primary current, such as to produce the effective rotation of the molten metal moving therein. The invention is particularly suitable for the continuous casting of slabs, using a submerged nozzle with lateral outlets.
摘要翻译：本发明涉及一种用于金属，特别是钢的连续铸造设备，其中浸入式喷嘴（8）被环形电磁感应器（1）围绕，该环形电磁感应器具有围绕铸造轴线旋转的磁场，该磁场旨在驱动熔融金属与其轴向旋转。本发明的特征在于，上述电感器是多相型的，其磁场穿过其中，并且每相配备有一对凸极（3）。而且，与喷嘴相对的每个突出极的端部设置有横向狭窄部12，该横向狭窄部12增加了分隔极性端部4的距离。以这种方式，感应器非常紧凑并且非常强大，并且可以使用高频一次电流向喷嘴的中心部分提供强烈的横向场，从而产生在其中移动的熔融金属的有效旋转。本发明特别适合于使用具有侧向出口的浸入式喷嘴来连续铸造板坯。

摘要： The invention relates to a contact lens having at least two focal lengths, a single lower supporting element (1) enabling the lens to be moved in translation in relation to the eye and a region (9) in the lower part of the lens, which region (9) has an outer face connected to the rest of the outer face (E) of the lens by means of a recess and an inner face merging with the rest of the inner face (i) of the lens, said recess defining the lower supporting element (1). The lens is characterised in that the aforementioned region (9) is thin, having an average thickness (e4) of the same order of magnitude as the thickness (e1) of the upper edge (3) of the lens.
