| description | FIELD: metallurgy. ^ SUBSTANCE: method for monitoring and controlling operation modes of scull vacuum electric arc furnace comprises steps of controlling voltage drop on arc and inter-electrode spacing; additionally creating in crucible volume sign-variable magnetic field whose intensity vector is directed normally relative to vector of electric arc discharge current; cyclically moving arc discharge along end of consumable electrode; monitoring electric arc discharge along end of electrode by means of program controlled video camera. Duration and intensity of pulses of sign-variable magnetic field is controlled by means of coils. Melt in crucible is agitated in horizontal and vertical planes due to interaction of coil magnetic field with electric currents spreading along scull. ^ EFFECT: improved explosion-proof properties of vacuum electric arc scull furnaces, enhanced uniformity of melt. ^ 2 dwg |
