Power Systems
(1) thermal power plants, steel mills, cement plants and other large industrial coal / oil CFB boiler and coal boilers, "four" ( ie water wall tubes, superheater tubes, reheater tubes, economizer / fuel tubes ) variety of construction technology advanced nickel-chromium coating spray LX34 / chromium carbide, LX88A super-hard wear-resistant alloy coatings, wear-resistant ceramic coatings and other corrosion resistant ceramic chip and so on.
(2) thermal power plant turbine blades fan blades, long-term abrasive wear by a certain temperature, the use of nickel-based tungsten carbide spray intensive life can be greatly improved. Currently Beijing, Xian, Gansu, Sichuan, Shenyang and other places of power plant turbine blades using nickel -based tungsten carbide spray method has a lot of success stories.
(3) thermal power plant steam turbine cylinder head sealing surface repair;
(4) Water Gate hydropower, buck stop distribution equipment, high-voltage transmission towers and other zinc spray, spray coating long-term corrosion protection of aluminum and its alloys;
(5) Turbine hydropower sites such as overcurrent runner, water flowing leaves, bottom ring, cover, tail pipes and other anti-cavitation erosion spray layer;
(6) diesel generator repair of worn crankshaft;
(7) the base of the wind power spray.
Metallurgical systems ( high temperature resistant coating applied in a variety of hot-rolled tools )
(1) rolling seamless steel pipe rolling mill seamless former top general roll top of molybdenum-based alloys, to name Steel seamless tube plant, for example, the inner diameter of 160mm seamless pipe rolling head, at high temperatures (1000) work environment, the general use of 6 to 8 times, and now with 45 # forged steel for the substrate surface using plasma arc spray superalloy powder, manufacture of composite roll top, its life expectancy has increased to 30 to 38 times, has been in seamless Steel plant uses, substantial economic benefits. Major equipment: plasma spray equipment, investment several hundred thousand dollars.
(2) a variety of guide and guard rolled steel plates, tubes, rods and other steel products, guide and guard plate ( round), formerly general cast iron or steel, not high temperature corrosion, using 45 # for the substrate surface spray High temperature solder alloy powder, life can be greatly improved, this process has been in many other Shougang steel enterprise applications, belong to the large surface, it is worth developing applications.
(3) Strengthen caster cut leaf leaf-cutting steel casting machine, import parts to cut tens of thousands of times, thousands of times domestic scissors, using powder surface superalloys strengthened its leaf-cutting performance accessible or reach the level of imports, be vigorously developed.
(4) steel wire drawing machine reel in the drawing process, the wire and roll over the line is part of the long-term status of the hard surface wear, using a self -fluxing nickel-based super-hard wear-resistant tungsten carbide alloy powder oxyacetylene flame spray can strengthening its life than the original life expectancy has increased more than four times, the country has vigorously promoted by the spray and extend the life of the factory benefited large, spray benefited also large.
Nonferrous Industry
(1) copper processing plant, aluminum φ600 × 1100; repair φ850 × 1500 other rolls;
(2) Aluminum extrusion nozzle carbon electrodes repair;
(3) non-ferrous metallurgy, petrochemical tons or more water / hydraulic machine φ850 × 5500; φ280 × 2500 using the spray to reach all kinds of plunger wear surface enhanced;
Coal system
(1) mine shaft equipped with spray zinc, aluminum, plastic corrosion coating;
(2) coal scraper conveyor middle groove with alloy spray resistant coating;
Oil System
(1) oil derrick, the anti-corrosion coating sprayed aluminum surface in large steel oil storage tanks;
(2) enhanced oil drill pipe joints spray coating and large valve repair;
(3) a variety of pumps, plunger repair.
Preservative market
(1) the metal coating various containers, tanks, etc., using ordinary (A3) or steel surface coating 1Cr18Ni9Ti 0Cr, 00Cr steel and other materials, and then subjected to a sealing treatment, instead of the overall manufacturing stainless steel, there are many application examples; fertilizer the inner surface of carbonation tower plant, gas cabinets, wine storage tanks, beer fermentation tank, distilled tower, various chemical containers sprayed aluminum, tin, zinc, lead, stainless steel and other corrosion-resistant coating and large valve, butterfly valve repair;
(2) ceramic coating pharmaceuticals, biochemistry, food, chemical and steel enterprises to adopt the new system within the A3 reactor surface coating of alumina, titanium, chromium and other ceramic coating of vitreous enamel coating or replace the reactor partially repair the enamel coating off; enamel reactor or mixing pulp, leaves, partial destruction, can not be used, the use of ZK1532 cermet HVOF gun powder sprayed ceramic coating, and then sealing treatment, repair as new reactor is generally a value of at least a few one thousand to ten million, restoration and considerable benefits.
(3) plastic coated plastic powder flame spraying referred flame spray, mainly used for the purpose of powder coating to prevent corrosion. Is characterized by a thick coating, the coating is simple, light and easy to carry equipment can be made to the construction site, the direct spraying acid, alkali, salt various plastic coating, no heat curing device, particularly suitable for on-site construction of a large area of flame spray in terms of corrosion resistance, operating process, the operating environment can be partially replaced by heavy-duty coating and FRP Lining.
