Fan blade surfacing flux-cored wire and preparation method thereof

The invention provides a fan blade surfacing flux-cored wire and a preparation method thereof, and relates to the field of welding materials, the fan blade surfacing flux-cored wire comprises a steel belt sheath and a flux-cored material, the steel belt sheath is filled with the flux-cored material, and the flux-cored material comprises, by mass, 5-10% of flux-cored wire powder and 5-10% of flux-cored wire powder. The flux core material comprises the following raw materials of, by mass, 70%-82% of high-carbon ferrochrome, 4%-8% of manganese-silicon alloy, 3%-6% of silicon carbide, 2%-7% of carbonized ferrochrome, 0.8%-1.3% of ferrotitanium, 5.2%-6.0% of graphite, 1.3%-1.7% of ferrosilicon, 0.6%-0.9% of quartz and 3%-5% of cobalt powder. According to the wear-resistant flux-cored wire and the preparation method thereof, the high-chromium alloy cast iron is selected as a welding material, so that welded deposited metal is mainly composed of metallographic structures of martensite and alloy carbide, the characte
