Mercerizing whole-drawing stabilization production method of zinc-aluminum-rare earth alloy steel for bridge cable

The invention is applicable to the technical field of bridge cables, and provides a mercerizing whole-drawing stable production method of zinc-aluminum-rare earth alloy steel for bridge cables, which comprises the following steps: S1, firstly, a steel wire passes through a first tension wheel and a second tension wheel to form tension, and meanwhile, the steel wire passes through a guide device and a drawing die box to be drawn to a set diameter; s2, the steel wire in the S1 passes through a rotary die box, and the surface of the plating layer is subjected to finishing again; s3, dust on the surface of the steel wire finished in the S2 is removed through a dust removal device, and the cleaned steel wire is fed into a medium-frequency induction furnace; s4, heating the steel wire in a medium-frequency induction furnace, and cooling the heated steel wire in a cooling water tank; and S5, the steel wire cooled in the step S4 is dragged to a take-up machine through a dragger to be taken up, and therefore stable pr
