Abstract

Studies of welding and surfacing fluxes containing ladle slag of electric steel production of rail steel of EVRAZ ZSMK JSC were carried out. Welding under the flux was performed on the samples of sheet steel 09G2S by Sv-08GA wire using the welding tractor ASAW1250 at exhaust modes. Chemical compositions of welding fluxes and slag crusts were determined. Also, chemical composition of the studied welded samples was determined according to GOST 10543–98 by X-ray fluorescence method on XRF-1800 spectrometer and by atomic emission method on DFS-71 spectrometer. Metallographic studies were carried out with the use of an OLYMPUS GX-51 optical microscope. The content of total oxygen and surface oxygen was studied using the LECO TC–600 analyzer. The possibility of using technogenic waste products of metallurgical production is shown for the production of welding fluxes. The following components were used for production of welding flux: ladle slag of electric steelmaking of rail steel from EVRAZ ZSMK JSC; BSK barium-strontium modifier produced under the terms of 1717-001-75073896–2005 by NPK Metallotekhnoprom; slag of silicomanganese production from West Siberian steel plant; electro static dust of aluminum production from RUSAL (carbonfluor-containing supplement). The studies have shown the suitability of the use of ladle electric steel slag for welding and surfacing of alloyed metal. The introduction of various flux additives reduces the concentration of total oxygen in the weld metal, which in turn increases the toughness. From the point of oxygen concentration in weld metal and impact toughness, it is better to use silica-manganese slag and carbon-fluoride additive as flux additives.
