The invention discloses a short-process producing and processing technology for cold rolling ultrahigh strength steel. The short-process producing and processing technology comprises the following steps: hot rolled strip steel, serving as an incoming material, is treated by procedures before rolling such as acid pickling and the like, cold rolling, heat treatment and deformation and phase transition comprehensive treatment, enters a loop after the heat treatment and the deformation and phase transition comprehensive treatment, is suitable for changes of the rolling velocity and the punch velocity by regulating the loop capacity and can enter a punching and quenching technology after being shorn with fixed length; and after the ultrahigh strength steel is finished, a finished or semi-finished punching part is obtained. Short-process producing and processing equipment for cold rolling the ultrahigh strength steel comprises a cold continuous rolling unit, a degreasing device inlet frame, a degreasing device, a looping tower, an annealing furnace front tension controlling device, an annealing furnace, an annealing furnace back tension controlling device, a collecting box and the like. With the adoption of the short-process producing and processing process and equipment, the energy consumption is reduced, the energy is saved, and the production cost is lowered; and by adding the deformation technology in the heat treatment process of the ultrahigh strength steel, the purpose of synchronous deformation and phase transition of the ultrahigh strength steel is realized, and the using performance of the strip steel is improved.
