Processing method of multi-layer hot rolled steel coil core

The invention relates to the technical field of steel coil treatment, in particular to a multi-layer hot rolled steel coil core treatment method which comprises the following steps: (1) making a cutting mark on the end face of a multi-layer hot rolled steel coil; (2) cutting a traction hole in the innermost ring of strip steel; (3) placing a metal bar on the inner surface of the innermost ring of strip steel close to the traction hole, enabling one end of a steel wire rope to penetrate through the traction hole to be firmly tied on the metal bar, and enabling the other end of the steel wire rope to be firmly tied on a movable heavy object; (4) part of the roll core is pulled out, a movable heavy object is used for pulling the steel wire rope, and then the innermost ring of strip steel and part of the roll core are pulled out till the strip steel at the position where the cutting mark is located is pulled out; (5) the pulled-out strip steel is cut off along the cutting marks; and (6) resetting the cut roll cor
