Abstract | The present invention belongs to the field of coat plating in steel surface engineering, and relates to an industrialized whole continuous PVD production process of zinc magnesium alloy coating steel strip. The baseband of the zinc magnesium alloy coating steel strip is hot-dipped / electro-galvanized steel; a continuous PVD zone is arranged; in the zone, the steel strip enter into an inlet multi-stage differential pressure chamber (3); a baking degassing device (4) conducts vacuum degassing on the steel strip surface; a plasma bombardment device (5) conducts plasma bombardment on the steel strip surface; the steel strip enters into a DC magnetron sputtering unit (6), which is provided with a plurality of DC magnetron sputtering modules; the steel strip passes through an outlet multi-stage differential pressure chamber (7); the steel strip passing passed through to the continuous PVD zone is subjected to rapid diffusion annealing for 10-20s at 410-418 DEG C, so that zinc and magnesium generate reaction diffusion to obtain zinc magnesium alloy coating. The zinc magnesium alloy coating obtained by the whole continuous PVD production process provided by the invention has excellent corrosion resistance and comprehensive application performance. |
