Production process of high-tensile-resistance super-flat and super-straight stainless steel flat wire

The invention discloses a production process of a high-tensile-resistance super-flat and super-straight stainless steel flat wire. The production process comprises the following steps of S1, bus selection; S2, first-stage rolling; S3, second-stage rolling; S4, third-stage rolling; S5, fourth-stage rolling; S6, cleaning and drying; and S7, winding and packaging, wherein a bus is processed through the steps S1-S5 and cleaned and dried in the step S6 to obtain a finished product of the stainless steel flat wire, and the finished product is wound through a winding set. Bright stainless steel soft round wires are selected for step-by-step rolling, the flat wire with the same specification and hardness is rolled, the working time is shortened, and the processing cost is reduced; by adjusting a tensioning adjusting structure, the phenomenon that the flat wire is bent to influence the qualified rate of the finished product due to the fact that tension is formed due to different rolling wire outlet time in the finish
