摘要： Edge-dam blocks assembled with their upstream faces in keyed mating interengagement with downstream faces of adjacent blocks form an endless edge dam revolvable in a preselected path for defining a boundary of a moving-mold casting region. The edge dam keeps molten metal in the casting region. Upstream and downstream faces of adjacent blocks have mutually complementary shapes for minimizing intrusion of molten metal between abutting blocks. Keying engagement between abutting blocks prevents relative translational slippage of blocks toward or away from molten metal. An abuttable face on each block has at least one protrusion such as an integral elongated key extending perpendicularly to a casting belt associated with the casting region, or the protrusion includes two round pins having projecting tapered ends. Another abuttable face has a recess such as a keyway for snugly receiving a key on an adjacent block or has two tapered recesses for snugly receiving two tapered projections of an adjacent block. External edges and root fillets of keys (and shoulders and root fillets of keyways) are radiused with radii in a range between about 1.2 and about 3 millimeters. Blocks' lower surfaces are shown having slots for receiving a tension member. A key's lower end may be undercut near the slot for relieving stress concentration. A pair of parallel undercut fillets are shown extending along opposite sides of a key. They have a radius in a range from about 3 to about 5 millimeters.

摘要翻译： 与其上游面组装的边缘坝块与相邻块的下游面的键合配合相互接合形成在预选路径中可旋转的无限边缘坝，用于限定移动模铸造区域的边界。 边坝在铸造区域保持熔融金属。 相邻块的上游和下游面具有相互互补的形状，用于最小化相邻块之间的熔融金属侵入。 相邻块之间的键合接合防止块朝向或远离熔融金属的相对平移滑动。 每个块上的可接合面具有至少一个突起，例如垂直于与铸​​造区域相关联的铸造带延伸的整体细长键，或者该突起包括具有突出的锥形端部的两个圆形销。 另一个可接合面具有凹槽，例如键槽，用于紧密地接收相邻块上的键或具有两个锥形凹槽，用于紧密地接收相邻块的两个锥形突起。 钥匙（和键槽的肩部和根部圆角）的外边缘和根圆角的半径在约1.2和约3毫米之间的范围内。 块的下表面被示出具有用于接收张力构件的槽。 钥匙的下端可能在狭槽附近被切削以减轻应力集中。 示出了一对平行的底切圆角，其沿着键的相对侧延伸。 它们的半径在约3至约5毫米的范围内。

摘要： A process for the continuous manufacture of copper wire rod presenting both the good ductility of oxygen-free copper and the annealing capacity of the tough pitch copper, in which liquid copper is prepared containing from about 0.006 to 0.0095% by weight of oxygen, the said liquid copper is cast via an open pouring spout in a continuous casting machine having an inclined straight molding cavity for producing a continuous copper bar containing 0.01 to 0.02% by weight of oxygen and which consists of a shell of solid copper and a core of liquid copper, the said bar on leaving the casting machine is cooled by repeated and direct contact with a cooling agent for complete solidification and the solidified bar is guided towards a horizontal rolling mill known "per se" along a curved path the maximum curvature of which is less than 0.25 m.sup.-1, and the said bar is rolled into wire rod.

摘要： A mold with a cooling jacket for the continuous vertical casting of metal billets, comprising between the lower part of the mold and the jacket a tubular wall the upper part of which is surrounded by ribs forming with the external side of the wall and with the internal side of the jacket a plurality of channels, said tubular wall forcing the cooling liquid introduced laterally into the jacket first to rise, then to divide itself regularly between the said ribs and to form simultaneously a laminar flow, then to flow down in that state along the mold and to leave in that state the cooling space through an annular slot.
