As previously mentioned, in existing boiler water-wall tube abrasionproof etching method, using wearing-resistant tile be also known as anti-abrasion cover, wear strip,
Anti-friction protecting watt, abrasion-proof cover plate, corrosion protection cover board, boiler climb the methods of pipe, abrasionproof pressing plate, the laser with other water screen tube Wear-proofs
Cladding, build-up wear-resistant anti-corrosion and thermal spraying wear-and corrosion-resistant coating process are compared at low cost, and easy to operate, Wear-proof effect is preferable,
But heat exchange efficiency is lower.In consideration of it, the present inventor be directed to using wearing-resistant tile carry out boiler water-wall tube Wear-proof technology into
Numerous studies are gone.
The present inventor is the study found that because of the wearing-resistant tile internal diameter usually big 1-5mm of water screen tube outer diameter than used in, between tube wall
There are the heat exchange efficiencies that gap can seriously affect water screen tube.Further study show that wearing-resistant tile is consolidated by doubling fixation
It is scheduled on water screen tube the gap that can eliminate wearing-resistant tile Yu water-cooling wall tube wall, can significantly mitigate water-wall corrosion and abrasion is existing
As extending the service life of water-cooling wall, while increasing substantially the heat exchange efficiency for hanging the water-cooling wall of wearing-resistant tile.The present invention is exactly base

Water screen tube heating surface anti-erosion performance is directly detected using the actual consumption rate in production in the present invention.
IV, beneficial effect
(1) metal scuff-resistant coating is high-quality: wearing-resistant tile raw material be rolled plate and micro- melting welding, laser melting coating, CMT built-up welding etc. its
The coating of his water-cooling wall abrasionproof etching method preparation is fine and close compared to material, defect is few, cohesive strength is high, long service life.
(2) stock utilization is high, and environmental protection and energy saving: micro- melting welding had not only polluted environment but also power consumption by sandblasting, thermal spraying, remelting three
Technique composition.Wherein thermal spray deposition rate is 70% or so.Wearing-resistant tile is that press machine compression moulding is pollution-free, and leftover pieces can press
At wearing-resistant tile snap ring, 98% or more stock utilization, power consumption is small, environmental protection and energy saving;
(3) at low cost good in economic efficiency: abrasionproof tilt sickness and material can need any adjustment according to user.With micro- melting welding etc.
Technique is compared, if selecting identical Wear-proof material and identical coating layer thickness, since present invention process is simple, equipment investment
It is few, it is high-efficient, the cost of Wear-proof is carried out well below techniques such as micro- melting welding, CMT, laser melting coatings using the technology of the present invention.
(4) the high-efficient long service life of boiler heat exchange: existing water-cooling wall pipe hanger wearing-resistant tile guard technology, wearing-resistant tile and water
There are gap, boiler heat exchange low efficiencys between cold wall pipe.Remarkable advantage of the invention is the high-temperature plastic with SiC particles reinforced
Stick fills its gap.Silicon carbide is a kind of thermally conductive and good thermal stability wear-resistant material.Its thermal coefficient 83.6W/m.K,
And the thermal coefficient of ordinary carbon steel is 45W/m.K or so, stainless steel thermal coefficient is only 16W/m.K.Boiler heat exchanger is done, it can
Burnup reduces 20%, saves fuel 35%, and productivity is made to improve 20-30%.In addition, can after wearing-resistant tile is worn through as interlayer
To play the role of Wear-proof, extend membrane wall service life, improves economy of power plant benefit.With the high temperature resistant of SiC particles reinforced
Adhesive density is low, light-weight, stable chemical performance, microhardness 2840-3320kg/mm2, hardness high abrasion, specific gravity is
3.20-3.25 is light-weight, and rub proofness is 6-7 times of common wear-resistant material.Gap carbonization between wearing-resistant tile and water screen tube
The high-temperature resistance adhesive filling of silicon particle enhancing, is compressed by wearing-resistant tile snap ring, is tightly combined, heat exchange efficiency is high, service life
It is long;
(5) scuff-resistant coating bond strength is high: for the high temperature resistant gluing for preventing SiC particles reinforced after wearing-resistant tile abrasion failure
Agent falls off, and the sandblasting of water screen tube heating surface is roughened before gluing, and the stainless-steel sheet network pressure of 3-5mm thickness is welded at wearing-resistant tile shape
On membrane wall fin, the high-temperature resistance adhesive of SiC particles reinforced fills the hole of expanded metal lath with pressure.Wearing-resistant tile is fixed
After also compressing wearing-resistant tile by wearing-resistant tile snap ring in addition to the high-temperature resistance adhesive of SiC particles reinforced is Nian Jie with membrane wall, abrasionproof
Watt snap ring and membrane wall fin reinforcement of weld.
(6) simple process productivity is high: wearing-resistant tile, expanded metal lath and clip forming can mechanization high speed mass production.
Wherein by expanded metal lath be pressed into wearing-resistant tile shape can the compacting of large area, and can disposable large-area welding on fin.?
Between wearing-resistant tile and membrane wall snearing silicon carbide particle reinfored composite material adhesive and weldering wearing-resistant tile snap ring operating procedure it is simple,
Maturation, speed are fast.Membrane wall is indeformable in work progress, does not need subsequent shaping, daily achievable square meters up to a hundred.With it is existing
The technologies such as micro- melting welding are compared, and daily yield is about its several times or more.
(7) maintenance of coke oven is good with high-temperature agglomerant high-temperature behavior: product is nontoxic, tasteless, and hot adaptability can be strong;Mechanical strength
It is high: can be used under 1100 DEG C of high temperature.High, wear-resisting antidetonation anti-strip, firm and durable with silicon carbide bond strength;Site operation side
Just: construction is not influenced by seasonal climate and temperature, efficient and convenient;Long service life.Its service life is domestic tradition used at present
7-10 times of high-temperature plastic;Refractoriness: 1790 DEG C;Wet molten amount: 2300-2600Kg/m3;Bulk density: 3.22g/cm3;Loading is soft
Change temperature: 1420 DEG C;Thermal stability >=20:(800-950 DEG C);Apparent porosity 19%: (500 DEG C of compression strength MPa:80.2
×2h)42.3(1000℃×2h)38.3(1400℃×2h);Tack time: 35 seconds;Adhesion strength: 0.3MPa (900 DEG C ×
24h)0.2MPa(1100℃×3h);Maximum linear expansivity: ± 0.26%.The characteristics of adhesive is that high temperature resistance is good, can
Resistance to 1100 DEG C of high temperature.
Compared with existing water-cooling wall pipe hanger wearing-resistant tile guard technology, it is simple easy for construction that present invention utilizes its structures
Advantage overcomes biography by the high-temperature resistance adhesive of the snearing SiC particles reinforced between wearing-resistant tile and membrane wall heating surface
The low deficiency of system wearing-resistant tile heat exchange efficiency.Wear-resisting watt of bond strength and service life with water screen tube are increased substantially, is reduced
The frequency and cost of maintenance, improve the economic benefit of enterprise.
