Abstract
A fully instrumental continuous casting funnel mold emplyed Online at Algoma's thin slab casting machine has helped operating personnel gain valuable insight into shell behavior during casting. The effects of several process upsets - steady state and transient - on the solidifying shell, such as broad face crack, detachment of off-corner broad face from the mold wall, loss of taper, SEN rupture and detachment of narrow fance, can be readily observed in-situ during casting. In this paper, some of these phenomena are demonstrated in a series of video files. The information obtained from the instrumented mold, coupled with breakout prediction algorithms and heat flux data, have provided the operators with a powerful diagnostic tool to monitor the shell behavior in the mold and to restore steady state conditions if and when the process upsets occur.
