The ceramic wear-resisting pipe is manufactured by the centrifugal method of self propagating high temperature synthesis. is to put the steel pipe in the centrifuge tube mold, add iron oxide and aluminum powder mixture in the steel pipe, this mixture in the chemical known as the aluminum heat agent, when the centrifuge tube mold rotation reached a certain speed, after a spark to ignite the aluminum heat agent, the thermite immediately burn themselves, burning waves spread rapidly, in the spread of the intense chemical reaction.
Ceramic wear-resistant pipe is based on Al2O3 as raw material, rare metal oxides as solvents, by 1730 ℃ High-temperature sintering made of special corundum ceramics, and then wear-resistant adhesive combination of wear-resistant ceramic patches, according to different needs of the choice of wear-resistant ceramic patches, to meet the special needs of users of technical conditions. Wear-resistant ceramic patch is 280 times times the wear resistance of manganese steel, is 180.5 times times higher chromium cast iron. Widely used in power plant pulverized coal conveying, steel sintering dust removal, cement plant and other enterprises related equipment, pipelines.
Ceramic wear-resistant pipe product performance:
1, wear Resistance: ceramic composite steel pipe lining ceramic layer in the Al2O3 content is greater than 95%, micro-hardness hv1000-1500, and thus has a very high wear resistance, its wear resistance than quenched the medium carbon steels 10 times higher than tungsten carbide drilling.
2, corrosion-resistant ceramics are neutral materials, stable chemical properties, with excellent corrosion resistance and acid resistance, can resist a variety of inorganic acids, organic acids, organic solvents, and its corrosion resistance is more than 10 times times the degree of stainless steel.
3, excellent heat resistance, can withstand temperature of more than 2000 ℃, in the scope of -50℃~900℃ long-term work.
4, easy to weld: ceramic wear-resistant pipe can be welded through the outer steel pipe to achieve the purpose of connection, ceramic wear-resistant pipe can be welded, flange, flexible quick connectors, such as coupling, installation is very convenient.
