The invention relates to a technology and equipment for zinc impregnation in a non-vacuum environment. According to the technology, zinc impregnation treatment is performed on a metal workpiece in the gas shielding atmosphere with the preset concentration. With the technology, zinc impregnation treatment can be performed in the closed environment and can also be performed in the non-sealed environment. The equipment comprises an open zinc impregnation chamber and a shielding gas applying device; the open zinc impregnation chamber comprises a zinc impregnation space as well as an open workpiece inlet and an open workpiece outlet which communicate with the zinc impregnation space; and the shielding gas applying device is used for filling the zinc impregnation space with shielding gas, so that the gas shielding atmosphere is formed in the zinc impregnation space. With the equipment, the zinc impregnation treatment can be performed in the open environment, continuous industrial production of zinc impregnation can be realized, the production efficiency can be remarkably improved, and all that is required is to heat and cool the metal workpiece during continuous production, so that the energy consumption can be remarkably reduced, and the emission can be reduced.
