description The invention relates to the technical field of cold processing of metallurgy and discloses a high-strength high-temperature alloy rod cold-drawing method. The method includes the steps that 1, solid solution heat treatment is conducted on rods; 2, lubricating is conducted on the rods obtained in step 1 before cold drawing; and 3, cold drawing is conducted on the rods obtained in step 2, wherein the total deformation rate of cold drawing treatment ranges from 35% to 40%, cold drawing treatment is conducted at least four passes, the deformation rate of the first pass ranges from 12% to 16%, the deformation rate of the second pass ranges from 13% to 16%, the deformation rate of the third pass ranges from 9% to 11%, and the deformation rate of the fourth pass ranges from 5% to 9%. The rod cold-drawing method is easy to implement, high in working efficiency, high in yield of finished products, and capable of effectively overcoming the surface defects that it is difficult to mold due to high strength of the rods, dies are destroyed easily, the surfaces are scratched easily, and bamboo joint type wear is generated, so that the rejection rate is high and working efficiency is low.
