RT Special Compound Ceramic Wear Nozzle
RT special compound ceramic wear nozzle is a high-tech product of Henan province. It is developed and produced by our company, which has been granted three national patents. Its special structure and unique ceramics formulation are protected by law.
RT nozzle can provide customers with the normal service life of at least two cycles. It is widely used in all kinds of distributors, pressure-reducing orifice plates and critical velocity nozzles in the reverse recirculation system of catalytic devices in China. It has been recognized and promoted by LPEC, SEI and other domestic most famous design and engineering companies. More than 90% of customers in the domestic refining industry use RT ceramic nozzles of our company.
Application device: all kinds of distributor, pressure relief orifice plate, critical velocity nozzle.
Features of RT special compound ceramic wear nozzle
- RT nozzle uses AL2O3 as the matrix, which is composed of metal or alloy and ceramic. It has advantages of metal and ceramic, including high hardness, high strength, corrosion resistance, wear resistance, small linear expansion coefficient, and etc.
- As for the ceramics formulation of RT nozzle, polyvalent metals of the same lattice-type were added to improve the wettability of ceramics;
- In the manufacturing process of RT ceramics, metal additives react with the substrate to generate new ceramic phases at the interface, such as Cr2O3. AL2O3 solid solution and FeO.AL2O3 spinel, so as to connect the metal and ceramics together, and maintain the characteristics of impact resistance and thermal shock resistance.
- RT ceramics adopts staged calculations system, mix the oxide films and AL2O3 to form solid solution, so that the metal and ceramic solid two-phase are connected together as whole, reduce difference of two-phase linear expansion coefficient, avoid too much stress, especially the destruction from the metal phase to ceramic phase, achieve high strength and abrasion resistance.
