Stable rolling production system for special alloy ultra-thin strip

The invention relates to a stable rolling production system for a special alloy ultra-thin strip, which comprises a cross-domain traceability system and a rolling mill control system, and rolling of a target strip to be rolled is controlled according to rolling process data calculated by the cross-domain traceability system; the edge finding and thickness measuring system is used for detecting the thickness of the target strip to be rolled; the belt breakage early warning system is used for detecting and judging whether the to-be-rolled target belt material has belt material edge cracks or not; and if the strip breakage early warning system judges that the to-be-rolled target strip has edge cracks, the rolling mill control system controls the rolling mill to stop. The method comprises the following steps: automatically retrieving first-pass empirical data of a rolled process according to the specification of a raw material to be rolled, calculating, issuing and finishing rolling of a first-pass unsteady accel
