METHOD OF MONITORING FOR DAMAGE TO SOLIDIFIED SHELL OF METAL CASTING PRODUCE DURING REMOVAL OF CASTING FROM HORIZONTAL CONTINUOUS CASTING MACHINE.

摘要

This method monitors for damage within a horizontally mounted mold to a solidified shell of a casting of molten metal produced by the horizontal and continuous removal of the casting from the mold, by a plurality of clamping rods, via a brake ring, on a feed nozzle mounted horizontally in an opening in the lower part of a side wall of a tundish containing molten metal. The method comprises the steps of continuously measuring the strain on any of at least one of said plurality of rods and a sleeve engaging with at least one of said plurality of rods, and monitoring for damage within the mold to the shell of the casting by taking an abrupt change in the measured strain to be due to damage to the shell of the casting within the mold.
