Description
54) СПОСОБ ВОССТАНОВИТЕЛЬНОЙ ЭЛЕКТРОПЛАВКИ54) METHOD OF RESTORATIVE ELECTRIC Fusion
1one
Изобретение относитс к области черной металлургии, в частности к производству ферросплавов в элекропечах.The invention relates to the field of ferrous metallurgy, in particular to the production of ferroalloys in electric furnaces.
Восстановительна электроп авка ферросплавов осуществл етс при посто нных в течении цикла значени х напр$ жени и тока.The reduction electric current of ferroalloys is carried out at constant values of voltage and current during the cycle.
Доказано, что полезное сопротивление ванны В течение цикла плавки закономерно мен етс в 1,2-3 раза. При посто нном отношении тока к напр шнию эти измененн 1ФИВОДЯТ к значительному перемещению электродо). Известно, что дл поддержани оптимального распределени энергии между шихтой, дугой и расплавом необходимо удерживать электроды на некоторых посто нных уровн х погружени .The useful resistance of the bath has been proven during the melting cycle to regularly change by a factor of 1.2-3. At a constant current-to-current ratio, these are changed (FIRST to a significant movement of the electrode). It is known that in order to maintain an optimal distribution of energy between the charge, the arc and the melt, it is necessary to hold the electrodes at some constant immersion levels.
Пель изобретени - экономи электроэнергии и повьниение срока службы футеровкPel invention - save energy and increase the life of the lining
Дл достижени этой цели в течение О,О5-0,5 длительности цикла в его начале плавку ведут при пониженном в 1,О2-2,5 раза отношении рабочего тока к напр жению.To achieve this goal, for O, O5-0.5, the duration of the cycle at its beginning, the melting is carried out at a reduced ratio of 1, O2-2.5 times the ratio of operating current to voltage.

ii
Способ восстановительной электроплавки металлов и сплавов при переменных электрических параметрах в печах с цикличным выпуском , отличающийс тем, что, с целью экономии электроэнергии и повыше-Л ни срока службы футеровки, в течение 0,О5-О,5 длительности цикла в его начале плавку ведут при пониженном в 1,О2-2j5 раза отношении рабочего тока к напр жению.The method of reducing electric smelting of metals and alloys with variable electrical parameters in furnaces with cyclical release, characterized in that, in order to save electricity and increase the service life of the lining, during the 0, O5-O, 5 cycle times, at its start melting with a decrease in 1, О2-2j5 times the ratio of operating current to voltage.
