Abstract
The invention relates to alloy powder in the metallurgy industry for improving harness, erosion resistance and wearing resistance of a metallic surface material and prolonging service life of equipment, in particular to self-fusing powder of carbon vanadium cobalt alloy, the self-fusing powder is characterized in that 23% by weight of carbon, 35% by weight of vanadium and 42% by weight of cobalt are treated and synthesized to carbon vanadium cobalt powder, and 18% of the treated and mixed carbon vanadium cobalt powder is mixed with 82% of ferrous powder according to percent by volume. The self-fusing powder of carbon vanadium cobalt alloy disclosed by the invention has the advantages of making the hardness of the metallic surface material treated by carbon vanadium cobalt be larger than 58 HRC and improving the wearing resistance thereof for 30-50 times compared with that of the original metallic material.
Description
Technical field
The invention belongs to hardness, the raising corrosion-resistant and wearability of metallurgy industry in order to improve the metal surface material, the alloy powder that prolongation equipment uses is particularly about a kind of carbon vanadium cobalt alloy self-fluxing nature powder.
Background technology
Along with national economy is fast-developing, the coal industry also increases with the cement sectors demand day by day, and construction of coal mine is at large-scale development, the colliery with column demand every year all about up to ten thousand, cement plant roll more or less a hundred, so it is very big to keep in repair market.Increasing utilizes our alloy powder cladding and technique for overlaying; Column repair in the process use in the weld deposit process with roll carbon vanadium cobalt alloy powder have carbon vanadium cobalt dust proportion low weight in weld deposit process carbon vanadium cobalt dust fly upward the content that has reduced carbon vanadium cobalt and can not make it reach optimum performance, for this reason our specialize the welding block of carbon vanadium cobalt alloy self-fluxing nature powder.
Summary of the invention
The purpose of this invention is to provide a kind of carbon vanadium cobalt alloy self-fluxing nature powder, it can overcome above deficiency, improves hardness, corrosion and the wearability of metal surface material, prolongs the service life of equipment.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of carbon vanadium cobalt alloy self-fluxing nature powder is provided, it is characterized in that: it handles the synthetic carbon vanadium cobalt dust in back by carbon 23%, vanadium 35%, cobalt 42% raw materials by weight percent; By volume percentage will be handled mixed carbon vanadium cobalt 18% powder and the processing of 82% iron powder mix again.
Above-mentioned carbon vanadium cobalt alloy self-fluxing nature powder preparing process process is:
1) carbon vanadium cobalt is according to carbon 23%; Vanadium 35%; The weight percent of cobalt 42% was mixed, and mixed carbon vanadium cobalt dust is under-0.08 condition in vacuum, with insulation under 120 ± 5 ℃ the temperature two hours;
2) iron Fe powder was under-0.08 condition in vacuum also, with insulation under 120 ± 5 ℃ the temperature two hours;
3) get carbon vanadium cobalt mixed-powder percentage 18% preparation that accounts for cumulative volume by volume after the above-mentioned processing; Get the 82% iron Fe powder that accounts for cumulative volume again and put into three-dimensional rotation batch mixer mixing carbon vanadium cobalt dust and iron Fe powder 8-12 hours;
4) then with 3) powder put ball mill into-24 ℃ to-30 ℃ ball millings 8-10 hours;
5) the carbon vanadium cobalt alloy self-fluxing nature powder behind the taking-up ball milling is under-0.08 condition in vacuum, gets final product in two hours with insulation under 120 ± 5 ℃ the temperature.
The present invention compared with prior art, advantage and effect that the present invention has are following:
This carbon vanadium of the present invention cobalt alloy self-fluxing nature powder is that a kind of equipment corrosion that is applied to coal mining and cement sectors, wear-resisting, hardness improve greatly, and also the time of having practiced thrift has been improved production efficiency simultaneously, thereby has improved profit.
Technical parameter and performance indications compare:
Hardness: original metal material surface hardness is 40～45HRC;
Carbon vanadium cobalt alloy metal material surface hardness of the present invention is＞58HRC;
Wearability: improve 30～50 times than original metal material wearability.
The specific embodiment:

This carbon vanadium of embodiment cobalt alloy self-fluxing nature powder, it handles the synthetic carbon vanadium cobalt dust in back by carbon 23%, vanadium 35%, cobalt 42% raw materials by weight percent; By volume percentage will be handled mixed carbon vanadium cobalt 18% powder and the processing of 82% iron powder mix again.
Above-mentioned carbon vanadium cobalt alloy self-fluxing nature powder preparing process process is:
1) carbon vanadium cobalt is according to carbon 23%; Vanadium 35%; The weight percent of cobalt 42% was mixed, and mixed carbon vanadium cobalt dust is under-0.08 condition in vacuum, with insulation under 120 ± 5 ℃ the temperature two hours;
2) iron Fe powder was under-0.08 condition in vacuum also, with insulation under 120 ± 5 ℃ the temperature two hours;
3) get carbon vanadium cobalt mixed-powder percentage 18% preparation that accounts for cumulative volume by volume after the above-mentioned processing; Get the 82% iron Fe powder that accounts for cumulative volume again and put into three-dimensional rotation batch mixer mixing carbon vanadium cobalt dust and iron Fe powder 8-12 hours;
4) then with 3) powder put ball mill into-24 ℃ to-30 ℃ ball millings 8-10 hours;
5) the carbon vanadium cobalt alloy self-fluxing nature powder behind the taking-up ball milling is under-0.08 condition in vacuum, gets final product in two hours with insulation under 120 ± 5 ℃ the temperature.
