    • Apparatus for pouring molten metal comprises a water cooled copper crucible 15 which has a recess adjacent its top and a pouring spout 16 positioned in the recess just below the level of the surface of the melt. The recess defines a lip above the spout which helps to ensure that there is a constant pressure head above the spout. Pivotally mounted on the lip, and biased to assume a horizontal position irrespective of the angle of tilt of the crucible is an induction coil 21. The coil induces currents in the surface of the melt and thereby moves the dross away from the pouring spout. The crucible 15 pours into a constant head hopper 22 and the opening and closing of the crucible pouring spout 16 and the angle of tilt of the crucible are controlled to ensure constant pressure head in the hopper.
    • 用于浇注熔融金属的设备包括水冷铜坩埚15,其具有邻近其顶部的凹部和位于刚好在熔体表面的水平面下方的凹部中的倾倒口16。 凹口限定出口上方的唇缘,这有助于确保在喷嘴上方有恒定的压力头。 偏心地安装在唇缘上并被偏置以呈现水平位置,而与坩埚的倾斜角度无关的是感应线圈21.线圈在熔体的表面中引起电流,从而将浮渣从倾倒口移出。 将坩埚15倒入恒定的顶部料斗22中,并且控制坩埚倾倒咀16的打开和关闭以及坩埚的倾斜角度以确保料斗中的恒定压力头。

    • A teapot ladle has an interior lining of low thermal capacity, low thermal conductivity refractory material which in contact with molten metal poured into the ladle forms an erosion resistant surface, and means for retaining the lining in place when the ladle is tilted.The lining material comprises inorganic fibrous material, particulate refractory material and an organic binder and the retaining means may be a refractory or metal ring which clips over the outer wall of the ladle and the inner wall of the lining, a series of clips or a rod shaped to fit over the top of the ladle and hold the lining in one place at one point on its perimeter.
    • 茶壶钢包具有低热容量的内部衬里,低导热性耐火材料,其与浇注到钢包中的熔融金属接触形成抗侵蚀表面,以及当钢包倾斜时将衬里保持在适当位置的装置。 衬里材料包括无机纤维材料,颗粒耐火材料和有机粘合剂,并且保持装置可以是夹在钢包的外壁和衬里的内壁上的耐火或金属环,一系列夹子或杆 形状适合于钢包的顶部,并将衬垫保持在其周边的一个位置的一个位置。
