Abstract
The invention discloses a gas-shielded overlaying flux cored soldering wire for repairing a hot-forging mould, which is manufactured by taking SPCC-SD cold-rolling low-carbon steel belts as raw materials of a soldering wire and utilizing a conventional flux cored transient alloy way, a universal flux cored standard and a flux cored soldering wire manufacturing technique. The soldering wire flux core contains fluoride, calcium carbonate, feldspar, magnesia and alloy powder according to a proportion, wherein the fluoride comprises calcium fluoride, sodium fluoride and barium fluoride, and the alloy powder contains iron powder, high-carbon ferrochrome, electrolytic manganese, ferrosilicon, ferromolybdenum, ferrovanadium, nickel powder, tungsten powder and cobalt powder. The invention has the following beneficial effects: because the gas-shielded overlaying flux cored soldering wire takes CO2 or a gas mixture with volume percentage ratio of 80% Ar and 20% CO2 as the protective gas, the gas-shielded overlaying flux cored soldering wire has the advantages of great soldering technique, stable electric arc, less splash, easy deslagging, good crack resistance, great high-temperature hardness and thermal fatigue resistance, continuous soldering and improvement on production efficiency.
Description
Technical field
The invention belongs to the welding material technology of preparing, particularly a kind of gas shiled flux-cored wire that is used for the reparation of forge hot pressing mold tool.
Background technology
The forge hot pressing mold will be repaired mold cavity after using several thousand times.Mould after the reparation can meet or exceed the life cycle before repairing.At present domesticly carry out the reparation of forge hot pressing mold tool and mainly adopt surfacing welding, efficient is lower.The employing flux-cored wire is repaired, and can realize continuous welding, enhances productivity.The welding slag of flux-cored wire is less than the welding slag of welding rod far away, has improved deposition rate, has reduced the workload of scarfing cinder.
Summary of the invention
The objective of the invention is to above-mentioned existing problems; A kind of gas shiled flux-cored wire that forge hot pressing mold tool is repaired that is used for is provided; Adopt the gas shiled built-up welding of this flux-cored wire to repair 5CrNiMo, 5CrMnMo forge hot pressing mold tool; Welding procedure is good, arc stability, splash little, be prone to take off slag, can realize continuous welding, enhance productivity.
Technical scheme of the present invention:
A kind of gas shiled flux-cored wire that is used for the reparation of forge hot pressing mold tool; With SPCC-SD cold-rolled low carbon steel steel band is the welding wire raw material; Adopt conventional medicine core transition alloy mode and general medicinal powder specification and the manufacturing of flux-cored wire production technology; The prescription of welding wire medicine core is made up of fluoride, calcium carbonate, feldspar, magnesia and alloyed powder, and said alloyed powder comprises iron powder, high carbon ferro-chrome, electrolytic manganese, ferrosilicon, molybdenum-iron, vanadium iron, nickel powder, tungsten powder and cobalt powder.
Said fluoride comprises the combination of calcirm-fluoride, sodium fluoride and any mass ratio of barium fluoride.
Be iron powder for fluoride 5%-10%, calcium carbonate 5%-10%, feldspar 1%4%, magnesia 1%-4%, high carbon ferro-chrome 15%-20%, electrolytic manganese 10%-15%, molybdenum-iron 4%-8%, vanadium iron 2%-5%, nickel powder 4%-8%, tungsten powder 5%-10%, cobalt powder 2%-5%, surplus in the percentage by weight of the prescription of said welding wire medicine core.
Formulation analysis of the present invention:
Said gas shiled flux-cored wire mainly is applicable to the reparation of 5CrNiMo, 5CrMnMo forge hot pressing mold tool, and this welding wire uses steel band to be ordinary carbon steel steel band SPCC-SD, adds wearability and temper resistance that high carbon ferro-chrome can increase steel.Addition through the adjustment high carbon ferro-chrome is controlled at 0.20%-0.35% with carbon content, and carbon content is low excessively, can not form enough Cr3C2 and WC, has reduced the hardness of deposited metal, influences the life cycle of repairing mould; And 5CrNiMo, 5CrMnMo belong to medium carbon low alloy steel, and the deposited metal carbon content is too high, very easily cracks in the welding process.In the slag making composition of welding wire medicine core, the adding of fluoride and calcium carbonate can increase the cracking resistance of deposited metal.
Good effect of the present invention: this gas shiled flux-cored wire; Adopting CO2 or percent by volume is that the gaseous mixture of 80%Ar and 20%CO2 is as protective gas; Welding procedure is good, arc stability, splash little, be prone to take off slag, the welding wire crack resistance is good; Have good high temperature hardness and heat-resistant anti-fatigue performance, can realize continuous welding, enhance productivity.
The specific embodiment
Embodiment:
