Metal surface efficient pickling process and equipment

The invention discloses a metal surface efficient pickling process which comprises the following steps of water washing, surface oil removal, blow-drying, pre-pickling, flushing, pickling passivation and follow-up treatment. Compared with the prior art, the metal surface efficient pickling process has the advantages that the pickling efficiency and the pickling effect are greatly improved, and the surface of a metal product obtained through pickling is provided with a layer of uniform and compact passivation film. The invention further discloses metal surface efficient pickling equipment which comprises an equipment body, a conveying support, a pre-pickling area, a washing area, a pickling passivation area, stirring motors and a conveying mechanism. Compared with the prior art, the manner that the plurality of stirring motors are arranged in the pre-pickling area and the pickling passivation area is adopted, in the pickling passivation process, a pickling solution and a pickling passivation solution are stirr
