Abstract
At Company «Zaporozhstekloflyus» the technology of two-stage melting of flux (duplex-process) was mastered, where firstly the charge is melted in separate melting unit, and then the melt is finally melted in another unit. This allowed decreasing the content of harmful impurities in melt: oxides of iron and sulphur by 2-3 times, phosphorus - by 4-6 times, and, thus, improving the flux quality. In addition, raw base for production of fused fluxes was widened that is extremely important under conditions of deterioration of raw material quality. Due to the double refining of melt of fluxes the duplex-process solved in principle the problem of utilization of slag crust, formed in submerged-arc welding. Production of fused semi-products designed for application in charge of welding consumables (covered electrodes, flux-cored wires and agglomerated fluxes) was mastered. 5 Ref., 1 Table, 1 Figure.
