Rare earth wear-resisting pipe
Purpose: high strength and low alloy steel tube a rare earth wearable used in thermal power plant boiler system, send powder, at the coal ash discharge pipe.Product performance1 comprehensive peformance is goodNew type of rare earth resistant alloy pipe is the EPC lost foam casting of the new process vacuum, the process can prevent all casting defects (porosity, slag, organization loose, large deformation) material component 2 original precious material: FeCr FeMn FeMo Ni Re FeSi basis, and add vanadium iron (FeV niobium iron (FeNb copper (Cu make this material has both high alloy casting wear resistance, and has high mechanical strength and impact resistance, while improving the material of the weldability, this material in the power plant, coal milling system powder manufacturing system, slag draining ash system, dense medium coal washing system pipeline, metallurgy system pipeline blast furnace slag the use of the more safe and reliable.2 high wear resistanceRare earth resistant alloy tube material has good abrasion resistance energy, joined the Fev FeNb Cu later material metallurgical structure and change, grain size, intensity is more close higher, more strong, and plasticity metal substrate, so that the original further passivation material wear-resisting performance and improve. HV1500-18003, high temperature resistance
The alloy element, Cr element of the Ni directly determine the content of heat resistance performance. Data Cr element, Cu elements of the content decided the material of a corrosion resistant capability, these elements of the component of the reasonable collocation, make this new type of rare earth resistant alloy material and with several performance, can adapt to all kinds of bad working conditions of use.4, the craft is advanced, stable performanceEPC lost foam casting process, vacuum new dimension precision tooling, material organization even, high performance is stable, especially for straight and different caliber pipe, differ wall thickness tube, eccentric tube, tapered tube can do the whole casting. Ceramic composite pipe than more stable performance.5, pipeline system running small resistanceDue to the change of metallographic composition, make casting matrix grain more close. The advanced technology and the original porosity, slag, organization of loose phenomenon get eradication, through a period after the pipe inner surface transport medium smooth as a mirror, greatly reducing the pipeline operation resistance, improve the life cycle of the piping and enhance the material wear-resisting performance.6, installation is convenient to useCan use flange, fast connection, direct welding way installation. FeV FeNb Cu join make because of new material through the heat treatment, hardness is improved, but also ensures that the material of optional cut, lack of change, welding, and other installation method. Its characteristic is in the same conditions and high manganese steel materials, the unit is wear than 1/3 of high manganese steel, high manganese steel service life is more than three times. The bend and branch pipe can be and seamless steel tube period of supporting the use for conveying pipeline irregular, manufacturing, cutting, welding convenient maintenance.
