![]() ![]() ![]() Suharno, Bambangįerrochrome is an important alloy in stainless steel making due to its contribution to high strength and corrosion resistance. ![]() It is shown that the rate of charge melting and the depth of submergence of arc discharges in the slag and metal melt can be monitored by measuring the vibrational characteristics of furnaces and using them in a universal industrial process-control system, which was developed for EAFs.Įffect of basicity on beneficiated chromite sand smelting process using submerged arc furnace The shielding of the acoustic energy fluxes onto water-cooled wall panels by a charge is experimentally studied. Acoustic vibrations are shown to transform into mechanical vibrations in the furnace laboratory. The processes occurring in arc discharges are analyzed as the sources of acoustic radiation in an electric arc furnace (EAF). New algorithm for controlling electric arc furnaces using their vibrational and acoustic characteristicsĬherednichenko, V. On average, the arcing is much less at 3% in SiMn and 5% in HCFeMn production. Plant-based measurements from a device called "Arcmon" indicated that in silicomanganese (SiMn) production, at times up to 15% of the electrical energy used is transferred by arcing, 30% in high-carbon ferromanganese (HCFeMn) production, compared with 5% in ferrochromium and 60% in ferrosilicon production. In processes where a crater forms between the charge zone and the reaction zone, electrical energy is dissipated mainly through arcing, e.g., in coke-bed based processes, through resistive heating. Electrical energy is dissipated to the process via a combination of arcing and resistive heating. Submerged-arc furnace technology is applied in the primary production of ferroalloys.
