Abstract
The invention discloses a flux-cored wire with high abrasion resistance and high performance/cost ratio, an external wrapper of which adopts H08A low carbon steel. The invention is characterized in that: a filling rate of the wire is 30 to 70 percent, percentages by weight of components of the wire and other components are: powdered graphite is 2 to 12 percent, high carbon ferrochromium is 25 to 85 percent, mid-carbon fe-mn is 2 to 15 percent, 45 ferrosilicon alloy is 1 to 7.5 percent, ferrovanadium is 1 to 26 percent, ferromolybdenum is 1 to 10 percent and reduced iron powder accounts for the residual percentage. The beneficial effects of the invention are that: the wire is processed through ordinary metal alloy powder lot, no pure metal or compound is needed, and the cost is relatively lower but the abrasion resistance is relatively higher, thereby being favorable for popularizing and applying widely.
Description
Background technology
Flux-cored wire is that the basis from flux-cored electrode tubular electrode grows up.Because flux-cored wire has arc stability, it is little to splash, it is attractive in appearance to be shaped, adjust medicine core prescription according to the needs of weld properties, can make in enormous quantities with actual welding in the superiority used continuously.Compare with solid core welding wire, stick electrode, the production efficiency height, welder's operating environment improves, and the comprehensive advantage of flux-cored wire is subjected to people's welcome deeply.Flux-cored wire has been widely used in building, bridge, chemical industry, metallurgy, electric power etc. and has made and repaired industry at present.
The ubiquitous problem of abrasion-proof overlaying welding flux-cored wire is at present: the flux-cored wire that price is low wears no resistance, and the import flux-cored wire price that wearability is good is too high.
Summary of the invention
The flux-cored wire that the purpose of this invention is to provide a kind of high abrasion high performance-price ratio.Its main component is elements such as carbon, chromium, silicon, vanadium, molybdenum and manganese, has high cost performance.
The present invention realizes with following technical scheme: a kind of flux-cored wire of high abrasion high performance-price ratio, and outer foreskin adopts H08A mild steel, and the filling rate of medicine core is 30-70%, and the component of medicine core and the percentage by weight of each component are as follows:
Powdered graphite 2-12%
High carbon ferro-chrome 25-85%
Mid-carbon fe-mn 2-15%
45 ferrosilicon 1-7.5%
Vanadium iron 1-26%
Molybdenum-iron 1-10%
The reduced iron powder surplus.
Utilize the filling rate of the flux-cored wire that the present invention makes between 30%-70%, to adjust according to on-the-spot applying working condition.Show that through practical application this flux-cored wire overlay cladding wearability height, good toughness, stress release are thorough, in service incrust, fall piece, with its development product overlay cladding average hardness HRC40-62, wearability be the 45# steel 4-25 doubly.Comparing cost with other similar products at home and abroad reduces more than 35%.Adopt the consumable accessory after this project is repaired, be more than 1.5 times of new accessory service life, but cost has only the 40-50% that buys new accessory, can save the great deal of steel and the duplication of labour simultaneously, has high economic benefit and social benefit.
The invention has the beneficial effects as follows: this core wire adopts the processing of ordinary metallic alloys powder, does not need simple metal or compound, and cost is lower, but has higher wearability, is convenient to large scale application.
The specific embodiment
Further specify the solution of the present invention and effect below in conjunction with embodiment.
Embodiment 1
