(speciality "Electric metallurgy")

chiefs: A. Ponomarenko

     A purpose of master's degree work is: Rise of going of suitable metal out at melting in super-power furnace and decline of stake of evaporating for melting.
     For achievement of the indicated purpose in the master's degree work the following tasks are decided:

• Drafting of material and power balances of melting
• Determination of stake of the heat expended on evaporation
• Determination of the optimum power entered from the furnace transformer at melting of wells in charge
  
• Determination of the optimum power entered from the furnace transformer in the period of finish melting charge
• Determination of the optimum power entered from the furnace transformer in the oxidizing period
• In the master's degree work the researches are conducted and got to dependence of stake of evaporating metal on the entered power for all melting and on separate its periods
  
• Are also collected dependences of intensity of evaporation of metal from the entered power at melting in electric furnace on periods and for all melting
