Abstract

The invention relates to a three-component alloy plating material for coated steel products with high corrosion resistance and the manufacturing method thereof. The three-component alloy is composed of Zn, Al, Si or a rare earth element. The plating material further contains a trace element as additive, wherein the trace element is selected from Fe, B, Pb, Mn, Ca, Cu, Sb, Sn, Ni, Bi, Ti, or a combination thereof; and the total amount of the trace element is below 0.5 percent. The manufacturing method is also disclosed, which comprises compounding the components at the given ratio, smelting in a smelting furnace at a smelting temperature of 750-800 DEG C, stirring in a non-contact manner, refining, slagging off, and casting to obtain an alloy ingot. The inventive coated steel product has high corrosion resistance, excellent fatigue resistance and strong ability of binding with matrix metals; and is widely used in the industries of household electronic appliances, construction materials and automobiles.

Description

Technical field [0001] The invention relates to a ternary alloy plating material and a manufacturing method thereof, in particular to a ternary alloy plating material of high corrosion resistance plated steel materials and a manufacturing method thereof. Background technique [0002] In the current domestic and foreign markets, due to the increasing demand for hot-dip galvanized or hot-dip galvanized alloy steel sheets in the fields of home appliances, building materials, automobiles, etc., most manufacturers are still producing and using traditional hot-dip galvanized steel sheets (with ) Or a hot-dip galvanized steel sheet (strip) containing only 0.1 to 0.2% Al. This product has many defects, short service life, only about 10 years of rust defects, and poor mechanical processing performance, the coating is easily damaged due to stretching, especially poor corrosion resistance under the condition of higher than room temperature. The joint between the plating layer and the base m...
