[0003] After annealing, the steel coil becomes loose and weak, and in the process of turning and hoisting, the steel coil is prone to deformation, increasing the difficulty of feeding the steel coil. Moreover, the tension leveling unit traditionally adopts a horizontal coil feeding mode, and for the loose steel coil after annealing, the interlayer slip phenomenon of the steel coil is relatively serious in the uncoiling process, causing an increase in the quality defects of the steel coil and a decrease in the yield.

[0013] Preferably, the magnetic force conveying belt is connected with a magnetic force generator.

[0014] Preferably, the convexity of the vertical tray is 5-10 mm, and the diameter of the vertical tray is 100-200 mm larger than the diameter of the steel coil.

[0015] Preferably, the top of the winding drum is conical, the winding drum is inflatable and shrinkable, and the length of the winding drum is not more than 60% of the width of the steel coil.

[0016] Preferably, the width of the magnetic force conveying belt is less than the width of the steel coil, and the length of the magnetic force conveying belt is 5-10 times the width of the steel coil.

[0017] Preferably, the first belt driving roller and the second belt driving roller are drum-shaped, and the center heights of the first belt driving roller and the second belt driving roller are the same.
