NOVEL SLIDE GATE PLATES WITH USABLE DUAL SURFACE AND NOVEL NOZZLES COMPATIBLE THEREWITH FOR SLIDE GATE ASSEMBLY.

摘要

The present invention aims at solving a longstanding problem of metal/alloy casting operation and achieve a considerable economic gain by providing novel slide gate plates with usable dual surface and nozzles compatible therewith for slide gate assembly, characterized in that both the surfaces of the said plates can be put to use, when working surface thereof erodes, the reverse non- worked surface may be turned over and utilized as an effective working surface, and is associated with nozzles of unique design which are compatible with said plates forming slide gate assembly.
