This utility model discloses an annealing heat treatment device for alloy bars, relating to the field of bar annealing heat treatment devices. The utility model includes a feeding mechanism, a transmission mechanism, and an annealing mechanism. The annealing mechanism includes a heating coil base. The utility model incorporates a collection mechanism, a collection box, a slag guiding surface, support legs, a dark baffle, and a blower.
