Undertake electricity resistant ceramic engineering

Introduction I undertake wear wear corrosion engineering, the main products are wear-resistant ceramics, wear-resistant ceramic coating, hardfacing plate, wear wear and anti-corrosion coating, etc., and provides construction. Wear-resistant ceramic coating is Wuhan East Zhen Technology Co., developed in cooperation with scientific research institutions, which is mainly composed of aggregates and ultrafine powder combined two-phase composition, particle closely packed, so there is no large macroscopic defects, bulk density, which at room temperature Under strength up to 200Mpa above. Ordinary pouring concrete and refractory materials can not match. Raw materials used mainly ionic compounds and some synthetic covalent compounds, based on solid theory, ionic and covalent bonds is a strong, and combined with the system due to the use of composite strengthening measures and special treatment, the formation of chemical bonding, so great strength and stiffness can effectively resist the high-speed impact and shear stress of the material. The use of special materials acid and alkali, stable performance, and the media does not react, but wear-resistant ceramic coating materials are mostly high-temperature composite materials, good crystal growth, structural integrity is not affected by environmental factors, it is the most One good inert material, which can protect against environmental effects and a variety of chemical corrosion medium. Wear-resistant ceramic coating wear resistance: To illustrate the wear-resistant ceramic coating wear resistance, to do a comparison test. (1) Comparative material: wear-resistant ceramic coating, 16Mn wear-resistant steel, 65Mn wear-resistant steel, refractory castable and wear-resistant ceramic. (2) Test conditions and procedure: Time: 15min; media: 0.5 ~ 1mm of corundum; Speed: 120m / s; spout to specimens of distance: 230mm; sample block vents and angle: 90 °. (3) Conclusion: room temperature resistant ceramic coating is 10 times the wear resistance of steel 16Mn, 65Mn steel 9 times, 50 times the refractory castable, with the change of the use of temperature increase wear resistant ceramic coating is very small. Wear-resistant ceramic Features 1. hardness Rockwell hardness HRA80-90, hardness only to diamond, far more than the wear resistance of wear-resistant steel and stainless steel. 2. Excellent abrasion wear resistance equivalent to 266 times the manganese steel, high chromium cast iron 171.5 times. Based on our 10 years of client follow-up survey in the same condition, it can extend the life of the equipment, at least ten times more. 3. light weight having a density of 3.5g / cm3, only half of steel, can greatly reduce the equipment load. The bonding firm, good heat resistance strength wear-resistant ceramic heat-resistant glue in the inner wall of the device. Long-term operation without aging at 350 ℃, temperature inorganic binder for cement products in 750 ℃. Adhesive heat resistance and adhesion performance indicators in the country ahead. 5. The wide range of applications for thermal power, steel, metallurgy, machinery, coal, mining, chemical, cement, coal ports and other enterprises, conveying systems, milling systems, ash, dust removal system and all wear and mechanical equipment on, you can choose different types of products according to different needs. My company has first-class construction team wear, Seiko secret agents, wear resistant ceramic works are carried out good quality, for the emergence of ceramic burst and off phenomenon, completely solve the ceramic wear fit is not the old technical problems. Hardfacing plate. Our company is the world's most advanced wearable surfacing technology, high wear-resistant alloy layer of plain carbon steel or stainless steel surface of the composite certain thickness, wear layer thickness uniformity and surface roughness of the double-metal composite anti- surfacing wear plate. Composite surfacing wear plate has can curl, cutting (plasma) and welding workability, the minimum can be rolled tubes do DN150-200 almost be used for various components of ordinary steel can be processed. The company can produce double-sided processing requirements sided abrasion resistant steel wear parts, such as the mill, vertical mill separator inverted cone like. Composite wear-resistant steel welding is characterized by a two-part general base and wear layers, wear layer and the substrate is completely metallurgical bonding, do not worry about the problem of wear layer off. The total thickness of the wear layer is generally 1 / 3-2 / 3, wear-resistant layer of the composite process, so that the state of anti-friction layer was cracked, and the crack does not extend to the base of the body, otherwise affect the carrying capacity of the matrix. But can not exist between the wear layer and the substrate cracks, deformation or wear layer will fall off during processing or in use, will not achieve wear in. Crack crack composite wear-resistant steel can be deformed as possible. Wear-resistant steel plate thickness of the standard series selection, generally have 3,4,5,7,9,11 like (open flat and thin thickness, such as the actual thickness of only 6mm thick steel plate 5.7-5.8mm, as a substrate by 5mm series of supply), wear-resistant layer thickness series: 3,4,5,6,9,11,15. In principle can be any combination of processing different specifications of dual-metal composite wear plate, but since the substrate is too thin and wear layer is too thick will cause wear plate deformation processing capacity drops, we recommend wear layer thickness of not more than two Select internal / 3 complex wear plate thickness range. We recommend Delivery Series: total thickness (thickness of the base material thickness + surfacing layer): 6 (3 + 3), 7 (3 + 4), 7 (4 + 3), 9 (5 + 4), 11 (5 + 6), 11 (7 + 4), 13 (7 + 6), 12 (7 + 5), 15 (6 + 9), 14 (9 + 5), 15 (9 + 6), 15 ( 6 + 9), 16 (11 + 5), and so on. Surfacing layer thickness error: + 0.5 / -0.00mm, steel base plate wear-resistant temperature of 350 ℃, stainless steel substrate can highest temperature 800 ℃.
