Claim:
1. A cold state metal plate strip surface treatment system, used for high-pressure jet-flow descaling and rinsing metal plate strips, comprises a high-pressure jet-flow descaling section, characterized in that, a tension unit and a stabilizing roller are provided in front of the high-pressure jet-flow descaling section, and a stabilizing roller, a compressed air drying device and a tension unit are provided after the high-pressure jet-flow descaling section; at least one descaling unit is provided in the high-pressure jet-flow descaling section, wherein the descaling unit comprises: first and second bending rollers used for bending a metal plate strip, and correspondingly first and second jet-flow descaling nozzles, and first and second rinsing nozzle sets, the second bending roller being disposed on an opposing side of the metal plate strip from the first bending roller and having an outer diameter smaller than that of the stabilizing roller in the front of the descaling section, such that there is an offset in height between an upper surface of the second bending roller and a lower surface of the stabilizing roller in the front of the descaling section between about 1 mm and 50 mm, the offset in height forming a wrap angle bending a surface of the metal plate strip between 1 and 10 degrees, wherein the first and second bending rollers disposed in the jet-flow descaling unit form stress cracks in the metal plate strip, which promotes the jet-flow descaling.
