Rare earth alloy tube
The material is the eighties by my unit and North Jiaotong University jointly developed a wear-resistant alloy materials.Through continuous improvement over the years, this alloymaterial has been serialized, the plant can meet various working conditions.
1. Powder feeding wear elbow boiler plant, ash slagging tube, after nearly two decades of use, won recognition.
2.The wear-resistant material with a number of other materials can not be universal advantages, such as bi-metallic materials can not produce coal grinding plant,
Milling, ash, slag system some equipment accessories. Such as slag scraper, coal mixer, spiral, etc., can use this material for power plant operation, maintenance and management, a great convenience.
3. Ingredients designed with multi-carbon alloy system to ensure that the material holding the comprehensive performance indicators. This material combined with our resources Characteristics, using a small amount of multi-alloy body, in the original alloy FeCr, FeMn, Ni, Re, again on the basis of FeSi added FeV, FeNb, Cu, and other alloying elements to ensure product performance.
4. Mechanical properties using improved detection methods, ensure the stability of the material properties.
5. Wear resistance, high wear-resistant alloy of rare earth material has a strong anti-wear performance,joined the FeV, microstructure FeNb, Cu took place after the material change, microstructure of lath martensite Belleville body. More fine grains, higher strength, more plasticity, and further passivated metal substrate, so that the wear resistance of the original material has been improved.
6. High temperature, corrosion resistance, abrasion resistance is improved. Ni alloy elements Cr content elements directly determines the temperature performance of the material. The elements Cr, Cu element determines the content of the corrosion resistance of the material, components of these
elements. Reasonable, so that the new wear-resistant alloys of rare earth materials also have several properties, such as both have high wear resistance, but also have high corrosion resistance, it can adapt to the harsh working conditions.
7. Advanced technology, stable performance, centrifugal casting, resin sand molding basis, the company introduced the EPC EPC vacuum suction casting new process based on product structure, purpose, use and quantity of tooling, high dimensional accuracy, uniform material structure, stable performance ,especially wear-resistant spiral, coal mixers, fork tubes, and export hopper, hemispherical dome joints, such as the cone shaped pieces done fighting the whole cast, uniform wall thickness.
8. Welding performance, can be cut, the implementation of low-carbon steel butt for operation and construction of various workplace environments, and easy to install.
9. Good hardenability properties, due to the wear-resistant alloy material Biaoliruyi under air quenching conditions, internal and external surface hardness of HRC difference of 1 to 2, to ensure that the wear performance.
