℃；
(3) ball blast: carrying out Shot Blasting to the oxide layer of steel surface, and the bullet that diameter is 0.2~3.0mm is thrown to workpiece
Surface makes the surface of workpiece reach certain roughness；
(4) cold rolling: successively carrying out pickling, rolling, degreasing, annealing and finishing to steel, steel with a thickness of 10- after cold rolling
30mm；
(5) phosphorus saponification process: by the steel elder generation phosphatization after cold rolling, then carrying out saponification process, is washed after the completion of saponification process with clear water
And it is dry, it takes the lead after dry；
(6) cold-drawn: steel are cooled to room temperature, and carry out drawing using drawbench, modification amount must not exceed the 10% of raw material；
(7) secondary heat treatment: control hardening heat is 600-630 DEG C, and 300-320 DEG C of tempering temperature, quenching oil temperature control exists
30-50℃；
(8) secondary cold-drawn: steel are cooled to room temperature, and carry out redraing using drawbench, modification amount must not exceed raw material
5%；
(9) pack: the band steel after secondary cold-drawn is cut off, is aligned, packaging.
Preferably, the phosphorus content of heretofore described steel is no more than 1.5%.
