Abstract

The invention relates to the field of flux-cored wires, in particular to a wear-resisting flux-cored wire. The flux-cored wire comprises the following components of, in percentage by mass, 30-42% of rutile, 4-7% of quartz, 2-5% of magnesia, 3-6% of potassium fluoride, 11-14% of nickel powder, 5-8% of medium-carbon ferrochromium, 6-9% of silicon-manganese alloy, 8-11% of feldspar, 1-5% of fluorite,4-7% of graphite and the balance of hafnium powder. Compared with a conventional flux-cored wire, the flux-cored wire is more wear-resisting.

Description

technical field [0001] The invention relates to the field of flux-cored welding wires, in particular to wear-resistant flux-cored welding wires. Background technique [0002] Flux-cored wire is a new type of welding material, which has the advantages of high benefit, low cost, high quality, etc. It inherits the adjustable electrode composition, overcomes the shortcomings of non-continuous and automatic welding of electrodes, and has high efficiency. , Welding seam forming is smooth and beautiful, and a series of advantages. Compared with solid cored wire, flux cored wire has the following characteristics: high production efficiency, flexible composition adjustment, energy saving and low pollution. For example, in the shipbuilding industry, flux-cored welding wire has replaced manual welding rods and solid welding wires, and has become the most consuming welding material. With its excellent properties of high strength, high toughness, crack resistance, and porosity resistanc...
