Title:
STOPPER ROD POSITIONING AND CONTROL APPARATUS FOR CONTROL OF MOLTEN METAL FLOW THROUGH A NOZZLE
Document Type and Number:
WIPO Patent Application WO/2010/132361
Kind Code:
A4
Abstract:
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.
