This invention discloses a high-speed slitting device for cold-rolled steel sheets, relating to the field of cold-rolled steel sheet shearing technology. It includes a shearing assembly for cutting cold-rolled steel sheet coils, with a pre-treatment box mounted on the front surface of the shearing assembly. In operation, the invention starts an electromagnetic rod and a rolling motor. The rolling motor drives a drive gear to rotate, which in turn drives two driven gears to rotate in opposite directions. These gears, through a gear ring, drive two toothed rods to rotate, further rotating the upper and lower rolling rollers to electromagnetically roll the two sides of the cold-rolled steel sheet. Combined with an eddy current sensor and a PLC controller, the magnetic field force is intelligently and dynamically adjusted according to the edge conditions of different hardness levels, achieving "flexible de-hardening." Then, a U-shaped focusing induction coil is activated to achieve rapid localized heating of the hardened layer, restoring the hardness to near that of the substrate, thus eliminating work hardening. The combination of magnetic rolling and localized heating softening achieves "full-thickness softening."
