The invention discloses a producing and processing technology of a superplastic pure iron material. The producing and processing technology comprises the following steps: (1) selecting a material: selecting a material which is produced in China and of which the type is CH1T as a base material; (2) performing drawing: drawing the material by a roller die drawing technique to obtain steel wires; and (3) performing annealing: using an isothermal recrystallization annealing technology, placing the steel wires in a heat treatment furnace, inflating the heat treatment furnace with inert gas, increasing the temperature in the heat treatment furnace to 660- 680 DEG C, keeping the temperature for 1- 2 hours, then performing cooling to 580-600 DEG C at a cooling rate of 15-20 DEG C/h keeping the temperature for 2-3 hours, and then performing cooling to room temperature at a cooling rate of 30-50 DEG C/h. The wire obtained by the processing of the producing and processing technology disclosed by the invention is high in plasticity, the wire does not crack after cold heading tests of deformation of 1/4 or above, and the wire has high elongation which is greater than or equal to 90%, ultra low hardness HV which is less than or equal to 90, refined grains with an average grain size level being greater than or equal to 11, uniform grain size, equiaxed grains and grain area difference being less than or equal to 5%.
