Abstract

The invention discloses a steel plate with a zinc-manganese-magnesium-silicon alloy hot-dip coating and a production method thereof. The steel plate with a zinc-manganese-magnesium-silicon alloy hot-dip coating includes a steel plate body and a zinc-manganese-magnesium-silicon alloy hot-dip coating; The zinc-manganese-magnesium-silicon alloy hot-dip coating covers the surface of the steel plate body; the composition of the zinc-manganese-magnesium-silicon alloy hot-dip coating contains 90-96 parts by weight of zinc and 1.0-5.0 parts of manganese , 0.5-1.2 parts of magnesium, 0.1-0.6 parts of silicon, 0.025-0.145 parts of vanadium, 0.008-0.105 parts of ruthenium, and the remainder includes unavoidable impurities. The coating of the steel plate with zinc-manganese-magnesium-silicon alloy hot-dip coating of the present invention, under the situation of the same coating thickness, has greatly improved the corrosion resistance of the traditional pure zinc coating, and the corrosion resistance has been several times higher It can meet the requirements of heavy anti-corrosion, such as the need for bridge steel wire in marine corrosive atmosphere environment, and has broad market prospects. In addition, the surface of the obtained coating is flat and smooth.

Description

technical field [0001] The invention relates to the field of steel plates, in particular to a steel plate with zinc-manganese-magnesium-silicon alloy hot-dip coating and a production method thereof. Background technique [0002] Metal parts of any type made of ferrous materials, more particularly parts made of steel, generally have applications requiring them to receive effective corrosion protection. In this regard, it is known practice to protect steel-based components from corrosion by galvanizing (galvanizing). In galvanizing, steel has a generally thin coating of zinc to protect the steel from corrosion. There are various galvanizing methods for galvanizing parts made of steel, in other words coating them with a metallic covering of zinc, including notably hot dip galvanizing, zinc metal spraying (zinc wire flame spraying), diffusion galvanizing (galvanizing), electrogalvanizing (electrolytic galvanizing), electroless galvanizing by means of zinc flake coating and mec...
