摘要： A stopper rod positioning and control apparatus is provided for controlling the flow of a molten metal out of a bottom nozzle in a metal reservoir. The stopper rod can be aligned with the nozzle's opening by selectively rotating a pair of roller (ring) bearings that are centerline offset from each other along a first axis around which one end of an extended structural arm can pivot where the opposing end of the arm retains the stopper rod along a second axis parallel to the first axis. When the appropriate relative positions of the pair of roller bearings are located for a nozzle-centered stopper rod, the second axial position of the stopper rod is fixed by retaining the appropriate relative positions with a brake mechanism. In a dual nozzle bottom pour reservoir of molten metal a separate stopper rod positioning and control apparatus is provided for each of the two nozzles while a dual nozzle assembly may be utilized to facilitate replacement of a worn nozzle or alter the distances between the centers of the two nozzles.
摘要翻译：提供一种塞杆定位和控制装置，用于控制熔融金属从金属容器中的底部喷嘴流出。可以通过选择性地旋转一对辊（环）轴承来选择性地旋转一对辊（环）轴承，所述一对辊（环）轴承沿着第一轴线彼此偏心，所述第一轴线围绕其延伸的结构臂的一端可枢转，沿着平行于第一轴线的第二轴线保持止动杆。当一对滚子轴承的适当的相对位置位于喷嘴中心的塞杆上时，通过用制动机构保持适当的相对位置来固定塞杆的第二轴向位置。在熔融金属的双喷嘴底部倾倒储存器中，为两个喷嘴中的每一个提供单独的塞杆定位和控制装置，而双喷嘴组件可用于便于更换磨损的喷嘴或改变磨损喷嘴的中心之间的距离两个喷嘴。
