The total energy consumption on smelting from converter slime was analyzed by two process flow sheets of the recycling: 1. pelletising - metallization in rotary furnace - melting in blast furnace. 2. briquetting - melting in blast furnace. The total energy consumption was calculated by using the results of mathematic modeling & material & thermal balance. Minimal gas emissions & energy consumption on iron smelting from slime can be accomplished during its recycling by means of briquetting. The energy consumption on iron smelting from mill scale during its recycling was analyzed according to the same pattern: 1. agglomeration - melting in blast furnace. 2. briquetting - melting in blast furnace. By total energy consumption, scale briquetting has an advantage over its agglomeration. Realized research shows the energy advantages of recycling technology by briquetting & melting in blast furnace.
