Self-Protection of Flux-Cored Wire Surfacing is Applied to the Enhancement of Chute Lining Board

Abstract:

Self-protection of flux-cored wire surfacing is a new way to improve mechanical parts surface properties, and can improve mechanical equipment in the harsh condition of wear-resisting, corrosion resistant, high temperature resistant and oxidation resistance abilities. This paper based on this technology, research on its reinforcement in the roof without bells chute board, first analyzes the board of chute working conditions, stress and aggrandizement requirements, and using ANSYS simulated the displacement field and the equivalent stress field during the impact process, to explain failure modes, Then from the view of experiment to research the effect of molybdenum and niobium self-protection of flux-core wire, the hard facing layer microstructure analysis show that hard facing layer can obviously increase the matrix micro hardness and impact toughness, The microstructure of Niobium surfacing layer is more delicate than molybdenum surfacing layer, impact toughness is higher and more suitable for strengthening chute lining board.
