Abstract
The invention relates to an electric arc spraying cored wire, in particular to a B-C compound hard phase wear-resistant electric arc spraying cored wire for protecting abrasion-prone areas of a utility boiler. The cored wire comprises the following raw materials in percentage by mass: 60-70% of ferroboron powder, 5-10% of Cr3C2-NiCr powder, 1-3% of Mo powder, 1-5% of Mn-Fe powder, 1-2% of Si-Zr-Fe powder, and Al powder and Mg powder in balancing amount. The electric arc spraying cored wire is based on a boride and carbide hard phase compound system, has favorable wear resistance when the boron-carbon ratio ranges from 8:1 to 10:1, endows a spraying coating with excellent high-temperature property through the addition of Mo, is free from obvious reduction of rigidity and wear resistance caused by temperature increase under 200 DEG C, and make up for performance deficiencies of like products during used in high-temperature environment. The cored wire has high bonding strength and low porosity and is far lower in cost than the traditional high nickel-chrome thermal spraying cored wire.
Description
Technical field
The present invention relates to a kind of electric arc spraying flux-cored wire, specifically for station boiler area protection easy to wear containing B, the wear-resistant arc spraying cored wires of C composite ganoine phase.
Background technology
The coal of power boiler burning mostly is meager coal or mixes coal, the SO2 producing in process of coal combustion, SO3, H2S, HCl, an alkali metal salt and vanadic salts class, the complicated Dynamic Corrosion process that number of chemical thing carries out tube wall at various temperatures jointly, the also erosive wear to boiler tube surface with ash particles of high-temperature flue gas.The temperature range that pulverized coal firing boiler eroded area is corresponding and wear form.Superheater tube skin temperature reaches 650 ℃, can reach 750 ℃ during tube wall coking, and the V-bar that flying dust impacts boiler tube is 15～40m/s, very easily suffers high temperature erosion/oxidation and high temperature corrosion.The high nickel chromium triangle hot spray wire that tradition protectiving scheme adopts, cost is expensive and to make a material processing requirement high.
Summary of the invention
In order to overcome above-mentioned defect, the object of the present invention is to provide a kind of B of containing, the wear-resistant arc spraying cored wires of C composite ganoine phase, prepares gained arc spraying coating and substantially reach traditional high nickel chromium triangle hot spray wire performance index, and cost reduces greatly.High-temperature behavior is superior, and bonding strength is high, and porosity is low.
To achieve these goals, the present invention adopts following technical scheme:
A kind of containing B, the wear-resistant arc spraying cored wires of C composite ganoine phase, the mass percent that each raw material of this material accounts for powder core is: ferro-boron powder: 60-70%, Cr3C2-NiCr powder: 5-10%, Mo powder: 1-3%, Mn-Fe powder: 1-5%, silicon ferrozirconium powder: 1-2%, Al powder and Mg powder: surplus.
In described ferro-boron powder, boron weight part content is more than 19%.
In described Mn-Fe powder, manganese element weight part content is more than 75%.
When in final mixed powder, the mass ratio of boron and carbon is between 8:1 to 10:1, this compound system has very strong wear resistance
In final mixed powder, Mo content, at 1-3%, makes spray-on coating have good high-temperature behavior, at 200 ℃, with interior, can Yin Wendu rising not cause lower hardness, and wear resistance declines, and has made up the performance deficiency that like product is used under 150-200 ℃ of environment.
Al in final mixed powder, the quality of Mg is between 5-10%, and during by spraying, exothermic heat of reaction makes coating have higher bonding strength and lower porosity.
Beneficial effect of the present invention:
This electric arc spraying flux-cored wire be take the compound system of boride and carbide hard phase and is basis, in boron carbon ratio example within the scope of 8:1-10:1, there is good wear resisting property, by the interpolation of Mo, make spray-on coating there is good high-temperature behavior, at 200 ℃, with interior can Yin Wendu rising, cause the remarkable decline of hardness and wear resistance, made up the performance deficiency that like product is used under hot environment.Bonding strength is high, and porosity is low, and cost is far below traditional high nickel chromium triangle hot spray wire.
