STOPPER ROD POSITIONING AND CONTROL APPARATUS FOR CONTROL OF MOLTEN METAL FLOW THROUGH A NOZZLE

摘要

A kind of stopper rod position control device provides a kind of for controlling flowing metal reservoir of the molten metal from bottom nozzle. Stopper can selectively rotate the structural arm that the biasing of a pair of rolls (ring) bearing mutual centre line extends around one end of first axle each other with the opening of nozzle can be with the opposite end at pivot, and arm holding stopper rod edge, which is parallel in the second axis of the first axle, to rotate. When a pair of of roller bearing of relative position appropriate is located at nozzle center's stopper, the second axial position of stopper is fixed on gear relative position appropriate and arrestment mechanism. In two nozzles of each offer of the container of twin-jet nozzle bottom pouring molten metal separated stopper rod positioning and control device, while twin-jet nozzle component can be used for being conveniently replaceable two nozzles at the distance between abrasion or change nozzle center.
