Abstract
The present invention discloses an anti-corrosion flux-cored wire. The anti-corrosion flux-cored wire comprises a steel sheath and powder; and the powder is formed by mixing components including, by weight, 8-10% of iron powder, 25-30% of silicon manganese alloy, 18-20% of rutile, 3-5% of wollastonite, 15-17% of ferrochrome, 8-9% of quartz, 0.3-1.5% of fluorite and 1-2% of ferrotitanium. Through increasing proportions of the rutile and the quartz, welding technology performance can be effectively improved; viscosity, melting point and surface tension of slag can be adjusted by the added wollastonite; weld forming can be effectively improved by adding the silicon manganese alloy; deposition efficiency can be improved and the number of depressions and gas holes can be reduced by adding the iron powder; the ferrochrome is added mainly for transiting an alloy element to weld metal; physicochemical performance of the slag can be improved by calcium fluoride in the fluorite; and crystal grains can be refined by titanium contained in the added ferrotitanium, thereby facilitating improvement of weld metal toughness. The flux-cored wire prepared by the powder has the characteristics that slag removal is easy, arc is stable, the weld metal toughness is high, and corrosion resistance is strong.
