Calculation and Analysis of Energy Parameters of Meltings in Eafs of Conventional and Consteel Design

详细

The calculation and analysis of the efficiency of various methods of heat introduction into a metal bath of the DSP-120 Consteel and conventional design furnaces were performed. The most effective method is the introduction of heat by way of electric arcs having an efficiency of 0.69 to 0.78. Heating of metal charge by gas-oxygen burner torches is less effective, and has the efficiency of 0.45 to 0.55. When heating metal bath by oxidation of coke, which is continuously introduced into slag for the purpose of foaming thereof, the efficiency constitutes 0.28 to 0.36.
