In Kashima Steel Works hot slabs supplied from two continuous casting machines are rolled at a hot strip mill in one rolling cycle.
Hence, in order to realize efficient casting and rolling operations while syncronizing these two processes under many equipmental and operational constraints, we have developed a consistent production control system, which includes the integrated cast and roll scheduling system and the instruction system for proper actions in case of abnormal occurrences.
In this paper we describe the concept of the mixed rolling schedule system(its aims, functions and features), and also its operational problems, improved points and a view for the future.
