Abstract
The invention provides a surfacing welding electrode for a sealing face of a valve, comprising H1Cr17 steel core wire and a coating, wherein the coating comprises the following components: 41-44% of marble, 17-20% of fluorite, 10-13% of quartz, 3-4% of titanium white, 9-10% of ferrotitanium, 3-4% of high carbon ferrochrome, 0.5-1.0% of ferrosilicon, 4.5-5.0% of metal chromium, 1.5-2.0% of nickel powder, 1.5-2.0% of ferromolybdenum, 2.0-2.5% of metal manganese and 1.0-2.0% of carboxyl methyl cellulose. The surfacing welding electrode is mainly used for surfacing the sealing face of a large valve and ensures that the surface of a surfacing layer is provided with alloy material components and hardness, therefore, the erosion from liquid pressure, temperature and chemical corrosion can be borne, the service life of the valve is prolonged, and meanwhile, the manufacturing cost of the valve can be reduced by adopting the surfacing welding electrode for surfacing.
Description
Technical field
The present invention relates to solder technology, more particularly, relate to the valve sealing face surfacing welding.
Background technology
The housing of valve and hydrodynamic reciprocating sealing face all adopt the manufacturing of cast steel technology, general material all adopts carbon foundry goods among ZG270-500, the ZG310-570 etc., the flow through fluid (gas or liquid) of valve, the branch that normal pressure, middle pressure, high pressure are arranged, the temperature of fluid has normal temperature, middle temperature, high temperature properties, fluid has the stronger ability to metal erosion, therefore in order to improve the service life of valve, need be coated with a kind of heap layer of alloy material to two sealing surface surface spraying welds, make the surface have higher hardness and abrasion resistance.The chemical composition of alloy material is related to again whether sealing surface can bear the impact of mesohigh or middle high temperature fluid and to the erosiveness degree of corrosive fluids.
At present the popular sealing surface surfacing of industry be coated with technology commonly used be plasma welding powder and two processes of welding rod built-up welding, have their own characteristics each at different occasion performance requirements, it is big to be coated with area for the sealing surface surfacing of large-scale valve, in batches after a little while, when being coated with technology with plasma spray, the one, the cost height, the 2nd, therefore the inhomogeneous easy generation distortion of being heated greatly of sealing surface area will adopt the surfacing welding bead-welding technology.But be not applied in the surfacing welding of large-scale valve sealing face in the market, make overlaying surface promptly will bear high-temperature, high pressure fluid and impact, the surfacing welding that has stronger corrosion resistance again is badly in need of the market development.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of at large-scale valve sealing face, makes the cladding alloying metal of sealing surface have surfacing welding of reasonable chemical composition and case hardness and preparation method thereof.
In order to address the above problem, the invention provides a kind of valve sealing face surfacing welding, comprise H1Cr17 steel core wire and coating, the component of described coating is as follows:
Weight percentages of components
Marble 41-44%;
Fluorite 17-20%;
Quartzy 10-13%;
Titanium dioxide 3-4%;
Ferrotianium 9-10%;
High carbon ferro-chrome 3-4%;
Ferrosilicon 0.5-1.0%;
Crome metal 4.5-5.0%;
Nickel powder 1.5-2.0%;
Molybdenum-iron 1.5-2.0%;
Manganese metal 2.0-2.5%;
Carboxymethyl cellulose 1.0-2.0%.
The above-mentioned valve sealing face preparation method of surfacing welding, coating makes up according to the above ratio, add binding agent, described binding agent is the potassium of high mode and the mixing water glass of sodium, is coated in H1Cr17 steel core wire surface after stirring, the moulding of welding rod extrusion, naturally dry behind the bistrique, 100～120 ℃ of low-temperature bakes 1～1.5 hour carried out 350～400 ℃ of high-temperature bakings 1.5 hours again, cool to 100 ℃ with the furnace and come out of the stove, treat that the welding rod temperature is reduced to below 40 ℃ to get final product.
(1) technical indicator of cladding metal level is as follows:
| C | Cr | Si | Ni | Mo | Mn |
| 0.20-0.40% | 12.0-15.0% | ≤0.9% | 1.0-1.5% | 0.5-1.5% | ≤1.0% |
(2) overlay cladding cladding metal hardness: HRC35-44.
The invention has the beneficial effects as follows: the present invention is mainly used in the sealing surface weld deposit of large-scale valve, make its overlay cladding surface have alloy material composition and hardness, can bear the erosion of pressure, temperature and the chemical attack of fluid, improved the service life of valve, use the surfacing welding built-up welding simultaneously, can reduce the manufacturing cost of valve.The present invention does not need when valve sealing surface build-up welding matrix heating, and weld deposit process does not have bubble, do not have fission, after the built-up welding matrix distortion little, the cladding metal level crystal grain thinning of overlaying surface has advantages of good abrasion, corrosion-resistant, high-temperature stability.
