The utility model relates to a prestressed anchorage pole heat treatment device, including mid -frequency induction hardening production line and the box tempering furnace that sets gradually. Compared with the prior art, the utility model discloses a method that online quenching of intermediate frequency response and box furnace tempering combined together, heat among the heat treatment process, cold technology cooperation is more reasonable, tempering temperature - is accurate, be favorable to reducing heat affected area and deformation, prestressed anchorage pole arbitrary cross section is tempered sorbite microstructure, total length within range mechanical properties and hardness are stable, tough performance balance, the deviation is no longer than 10%, workpiece surface sclerosis layer is more shallow, length direction's flat straightness is good, the deflection is no longer than 4%, the tip does not have crack phenomenon. Degree of automation is moderate for this thermal treatment method, and to the s
