This invention relates to the field of alloy cold heading steel production technology, and discloses a pearlitic phase transformation process for alloy cold heading steel that reduces or eliminates annealing. The process includes S1 precise composition design, S2 converter smelting stage, S3 LF refining stage, S4 vacuum treatment stage, S5 continuous casting stage, S6 rolling stage, S7 core controlled cooling stage for pearlitic phase transformation, S8 heat preservation and channel strengthening stage, and S9 process monitoring and closed-loop adjustment. This process achieves sufficient pearlitic phase transformation and significant suppression of harmful phases: by precisely controlling the cooling rate at 0.25-1.0℃ / s in the core controlled cooling stage, combined with heat preservation synergy within the 620-746℃ pearlitic phase transformation range, the pearlitic content of the steel is stably maintained at ≥85%, the bainite content ≤5%, and the martensite content ≤2%, completely solving the problem of excessive hardness caused by excessive harmful phases in traditional processes, and providing core microstructure protection for reducing or eliminating annealing.
