Intensification of the electro slag process exothermic mixtures (fluxеs)

It is established that an effective way to improve performance is to use the electro slag processes exothermic mixture (mechanical mixture scaling of aluminum powder and а standard flux) or flux exothermic (mechanical scaling mixtures, alloys, aluminum powder and a flux standard) in amounts sufficient for the exothermal reaction. Experimentally is defined the presence of the electrically conductive layer exothermic flux, allowing to carry out the electro slag process mono, bifilar or three-phase circuit using a "solid" start. The influence of the exothermic metal-flux mixtures to hold electro slag processes. Submitted exothermic flux composition consisting of a mixture of dross and aluminum powder, the alloying additives are calculations of thermal effects, and the optimal ratios and electrode coating formulation with the exothermic mixture. The results of investigation of influence of particle size distribution of ferroalloys on solubility in reducing metal when the exothermic reaction and the chemical composition of electro-metal. The dependence of the electro-chemical composition of the metal particle size distribution of ferroalloys and method of melting exothermic flux. The optimum particle size. When the exothermic process and the mixture of aluminum dross occurs to change the chemical composition of the slag at the expense of additional content of aluminum oxide formed, but it does not reduce the ability of fluoride desulfurizing flux used in the electro slag processes. The results of studies of formation of the metal structure using ekzosmesi content of nonmetallic inclusions. The results of technical and economic parameters ways start ESR. It is proved that the use of exothermic alloyed flux does not affect the quality of melted metal. The use of exothermic alloyed flux allows more efficient use flux melting furnace and put them in the manufacture of parts for various purposes. Introduction exothermic mixture or exothermic flux can increase productivity electro slag process
