Abstract In view of much uncertainty in the process of continuous casting, based on the introduction of fuzzy technology, the expert system of continuous casting slab quality justification was developed. Taking surface longitudinal cracks as example, the continuous casting slab knowledge database is set up with industrial operation data acquired in one medium plate plant as samples. The continuous casting slab quality is justified、reasoned and decided offline by positive reasoning system, the HMI is built up by VC++6.0 and oracle is adopted as database. The debugged result showed that the system has the higher justification accuracy (more than 95.6%),which provides the base for its online application.
