| description | The invention discloses a flux-cored wire for roller repair and a preparation method, the flux-cored wire comprises an outer skin and a flux core, and the outer skin is a low-carbon steel strip; the flux core is composed of, by mass, 12%-32% of high-carbon ferrochrome, 1.8%-4.6% of micro-carbon ferrochrome, 2.4%-4.1% of electrolytic manganese metal, 2.2%-4.5% of molybdenum metal, 0.5%-6.2% of ferrovanadium, 1.2%-2.5% of electrolytic nickel powder, 4%-6% of yttrium-based heavy rare earth ferrosilicon alloy, 5.0%-10% of ferroniobium, 20%-50% of reducing iron powder and 6%-12% of an active agent, and the filling rate of the powder is 20%-50%. The flux-cored wire for roller repairing has the advantages of being excellent in postwelding surfacing metal performance, good in high-temperature strength and high-temperature hardness and stable in performance, and the problems that in the prior art, after repairing is conducted, the rolling amount is not high, and the service life is short are solved.
