Study on Alloy Particles and its Deposited Metal Microstructure and Properties

Abstract:

A technology conception of producing filled metal particles which use steel scraps of steelworks as the main raw materials for welding was proposed in this paper. It provides a new resource for raw materials which are used to process welding material and the steel scraps are used sufficiently, reasonably and in high value-added at the same time. According to the wearing conditions of loader when it exploits and loads the river sand, the Fe-Cr-C alloy particles were designed. The technology of medium frequency induction furnace - centrifugal atomizer was used to get the alloy particles in 0.1~5.0mm diameter. Melt alloy particles by submerged arc welding and study the microstructure and properties of the deposited metal. Engineering application tests were also carried out and yield highly desirable results.
