The production method comprises the steps of molten iron desulphurization, converter smelting, alloying, continuous casting, heating, rolling and alloying continuous hot galvanizing. In the alloying continuous hot galvanizing process, after galvanizing and zinc pot delivery are carried out, the cooling speed of an upstream section is controlled to be higher than or equal to 40 DEG C / s, and the cooling speed is controlled to be higher than or equal to 30 DEG C / s after alloying. The deep-drawing zinc-iron alloy plated steel plate in which zinc-iron alloy plating surface grains are fine, distribution is even in size, the plating structure is compact (the area ratio of surface holes is smaller than or equal to 5%), and the surface is free of obvious microcracks is obtained on the premise that the mechanical performance of the steel plate is guaranteed. The anti-pulverization performance of the zinc-iron alloy plated steel plate is improved, the 60-degree V bending test grade reaches the first level, and the phenomena of pulverization and falling of a plating are not likely to happen in the steel plate punching molding process; and accordingly the purposes of quality and production of zinc-iron alloy plated steel plate workpieces are achieved.
