The invention discloses a production method for a hot rolling acid pickling automobile plate. The hot rolling acid pickling automobile plate comprises chemical elements including, by weight, 0.02-0.04% of C, smaller than or equal to 0.05% of Si, 0.20%-0.30% of Mn, smaller than or equal to 0.020% of P, smaller than or equal to 0.020% of S, 0.010%-0.020% of Nb, 0.030-0.050% of Als, smaller than or equal to 0.008% of N and the balance Fe and inevitable impurities. The preparing method for the hot rolling acid pickling automobile plate sequentially includes the following steps of molten iron pre-desulfuration treatment, converter steelmaking, steel ladle LF refining, continuous casting, casting blank heating, rough rolling, finish rolling, laminar cooling, high-temperature coiling, flattening,acid pickling, rinsing, oil smearing and coiling. By means of the production method for the low-carbon, low-manganese and low-silicon component design is adopted, the carton equivalent is reduced onone hand, and the steel plate welding performance is improved; on the other hand, ferrous silicate which is hardly subjected to acid pickling is prevented from being formed on the surface of a steel plate in the hot rolling process, and the surface quality of the steel plate is improved; a proper amount of Nb alloys are added, so that the strengthening effect of the Nb alloys is sufficiently achieved, and low-cost component design is achieved; and high-temperature coiling is adopted, the laminar cooling control difficulty is lowered, the steel roll through roll technology is stability, and thesteel roll plate shape quality and the through roll performance stability are improved.
