The function of each component of flux-cored wire of the present invention is:
Rutile: rutile is the main component that slag is formed, and can improve the spreadability of slag and the removability of slag of postwelding.Rutile has preferably impact to all positon, and the addition of its main component titanium oxide can significantly reduce high temperature viscosity and the surface tension of slag, and the decline of viscosity coefficient of dross can improve high-temperature slag breathability, thus face of weld speckle reduces.
Iron powder: its effect is to improve flux-cored wire deposition rate, the composition of regulation deposited metal forms weld metal.
Silicomangan: mainly deoxidizer, it is possible to decrease the oxygen content of weld metal.When its addition is less than 5%, deoxidation is deteriorated, and impact flexibility is deteriorated；Addition is more than 20%, then intensity is too high, and impact flexibility reduces, and can cause splashing.
Quartz: its Main Function is slag making.
Zircon sand: zircon sand acts primarily as slag making, adjusts the physical and chemical performance of slag, adds in right amount so that droplet size diminishes, and welding bead both sides are neat, can improve the all-position welding technique of welding wire.
Fluoride: it is arc stabilizer, dehydrogenation agent.When the addition of fluoride is less than 2%, arc stability is not enough, and dehydrogenation scarce capacity is easily generated weld porosity load mould；Addition is more than 6%, and electric arc is elongated, flue dust and increase of splashing.
Rare metal: be properly added rare metal in formula, the mechanical property making deposited metal is more stable, particularly low temperature impact properties, is not only greatly improved, but also makes impact property more stable.
The present invention has positive effect: flux-cored wire of the present invention is by coordinating slag making component and the addition of other function ingredients in medicated core, by controlling the addition of silicomangan, reduce the addition of alloying element, reduce the scaling loss of alloying element, accurately controlling in formula the trace element such as boron, the mechanical property making deposited metal is more stable, particularly low temperature impact properties, not only it is greatly improved, but also makes impact property more stable.
