The invention discloses a soft magnetic material annealing thermal treatment method. The soft magnetic material annealing thermal treatment method comprises the following steps of: S1, performing rust-removal treatment on a soft magnetic material; S2, performing de-oiling rust-removal treatment on the soft magnetic material; S3, drying the soft magnetic material; andS4, adopting a chain type furnace to perform annealing treatment on the soft magnetic material, wherein a furnace hearth of the chain type furnace comprises a first heating area, a second heating area, a first heat-preserving area,a second heat-preserving area, a first cooling region, a second cooling area and a cooling warm area from an inlet to an outlet. Continuous annealing thermal treatment is performed on the soft magnetic material under an unsealed environment, so that annealing efficiency can be greatly improved; an annealing curve is formed in each warm area, so that a microstructure of the soft magnetic materialcan be improved, magnetic conductivity of the soft magnetic material is improved, and coercive force of the soft magnetic material is reduced; after being subjected to annealing thermal treatment, thesoft magnetic material has high magnetic conductivity and low coercive force, and can quickly respond to outer magnetic field changes; and under the low coercive force condition, the soft magnetic material improves sensitivity of an electromagnetic product.
