Development of Flux Cored Wire Using Concentrates and Mining Industry Waste Products in the Far East

Abstract

The paper considers the problem of the development of new flux cored wires manufactured from concentrates and waste products of the mining industry of the Far Eastern Region. The authors provide the results of the analysis of the phase and chemical compositions of mineral raw materials, and experimental research. We have developed diagrams that offer a selection of different compositions of charge mixtures depending on the properties demanded from the weld deposited metal. We have also developed a flux cored wire for deposit welding of the automatic coupling locks of the rolling stock that ensures the hardness of the weld metal 500 НВ retaining high parameters of notch toughness (impact strength).

Investigation on Producing the Flux Cored Wire Modified with Concentrated Complex from Tomtor Mineral Assets

“…At the same time, research is being carried out on the possibility of the integrated use of mineral raw materials and the development of welding materials based on concentrates and wastes from mining production. [5,6] In this paper, electrometallization coatings from the developed experimental flux cored wires modified with a complex REM concentrate isolated from the Tomtor rare-metal deposit of the Republic of Sakha (Yakutia) were selected as comparative studies [7].…”

Intermetallides in the Structure of Gas-Thermal Coating With Additives of Complex Concentrate of Rare-Earth Element

“…At the same time, the search for new ways of complex use of mineral raw materials and the development of welding materials on the basis of concentrates and mining waste is carried out [6,7].…”
