Description

Rare earth alloy wear-resistant multi-way pipe is made of rare earth wear-resistant alloy steel contains various alloy elements such as Cr, Ni, Mo, W, V, Cu, etc.

excellent welding performance, with cuttability and the possibility of on-site drilling.This process can avoid pores, slag inclusion, loose assembly and large deformation. and other common casting defects, the material composition is based on the original FeCr, FeMn, Ni, Re, FeSi and other alloy materials, and ferrovanadium (FeV), ferroniobium (FeNb), copper (Cu) are added, so that the material has both high alloy The wear resistance of casting has high mechanical strength and impact resistance, and at the same time improves the weldability of the material. Rare earth alloy wear-resistant elbows are used in coal grinding systems, pulverizing systems, slag and ash removal systems, heavy medium coal washing systems, and slag transportation pipelines in metallurgical systems.

Rare earth alloy wear – resistant tube is badly worn parts, such as pipe, elbow, reducer, and water intake place such as the model of integral casting, then mechanical processing method, especially the outer wear parts, especially in the elbow to the outer diameter change circle method is adopted to carry on the design, local thickening severe wear parts, but also according to various requirements, produce all kinds of irregular switch pipe fittings to meet the design requirements, straight tube is using centrifugal casting.Rare-earth wear-resistant alloy containing Cr, Ni, V, Mo, W, a variety of alloy element such as Cu, it not only has high hardness, but also has certain mechanical properties, at room temperature with good welding performance, and can be cut and the possibility of opening, also has certain corrosion resistance.
